lcd panel rubbing cloth for sale

The good news is that cleaning a computer screen is more simple than you think. You only need a soft cloth, a tiny bit of water, and the most delicate of touches.

As you would expect, not all screens are created equal, and some are more delicate than others. The safest way to figure out the proper care for your screen is to search for the make and model of your device, find out if it has an LCD, LED, or some other type of display, and search for the manufacturer’s instructions on how to care for it.

If you want to skip all that, there’s an easy way to avoid making a mistake that might not only result in irreparable damage to your screen but to your entire device. According to Joe Silverman, owner of New York Computer Help, a tech repair center in New York City, no matter how much money you spent on your computer or tablet, it probably has an LED or an LCD screen if you bought it within the last three years—and neither type benefits from window cleaner or highly concentrated alcohol.

Caring for your screen is simple—it only takes a little bit of water and a dust-free cloth, such as a microfiber wipe or the piece of fabric that came with your glasses.

Pour a couple drops of water on your cloth. Forget paper towels or the sleeve of that soft cotton t-shirt you love—microfiber is your best bet. Still, no matter how soft it is, a dry wipe could always leave micro-abrasions on your screen. The moisture will also help gather dust and particles while lifting grease from your display.

Use circular motions starting in the center of your screen and moving outward, so you don’t leave any streaks. If you can see any droplets or water traces on the glass while you clean, you’ve used way too much water. Gently dab the residual H2O with an absorbent cloth or tissue paper and start again.

If you’re dealing with next-level gunk, you can use isopropyl alcohol at 70 percent or lower, Silverman says. “That percentage is very important,” he explains. “We’d only use 90 percent or higher on dummy parts that don’t have sensors, like top cases and keyboards.” In these extreme cases, spray the alcohol on the cloth, never directly on the screen, and wipe it gently.

The best way to avoid damaging your screen while cleaning it is to simply keep it from getting dirty in the first place. If you have a laptop, cover the keyboard with a thin microfiber cloth before closing it to prevent finger grease from transferring to the screen. If you have a touchscreen, wash your hands often before you use it, but make sure you let your hands dry completely before you start tapping—the soapy water or liquid hand cleanser from your fingers can easily end up on the screen and corrode it.

Silverman explains that most iPhones and Samsung phones, for example, have screens made out of one thick piece of glass. These, as opposed to computer screens, have all the LCD layers fused together, making them much more difficult to damage. Still, if you’re using alcohol, he recommends keeping the concentration at 70 percent or lower, using a soft cloth, and applying only low pressure to get rid of any accumulated gunk there.

Be especially careful with charging ports, as contact with water (also present in rubbing alcohol) can damage the electronics inside your smartphone. Newer models often are resistant to liquids, but there’s always a threshold to how much they can withstand. And you probably don’t want to know what that is.

The short version? Don"t use liquids, don"t press too hard, don"t use any traditional cleaners. Microfiber cloths are good, but be gentle. Modern TVs are predominantly plastic and therefore far easier to scratch than windows or your phone.

Want the longer version? Here"s what the top TV manufacturers say about cleaning their screens:Cleaning your 4K, OLED, or LED TV screen with a soft, dry cloth is recommended. The goal here is to avoid scratching the screen. Gentle, circular motions tend to give better results, since the circular motion hits each area from several angles in a single swipe.

To clean the frame and screen, gently wipe it with a microfiber cleaning cloth. Make sure to wipe the TV frame and screen as gently as possible. TV screens are fragile and can be damaged when pressed too hard.

Important: Never use any type of window cleaner, soap, scouring powder, wax, or any cleanser with solvents such as alcohol, benzene, ammonia, or acetone. Never use abrasive pads or paper towels. If you do, you can scratch the screen or strip the anti-glare coating off the screen and cause permanent damage. Never spray water directly onto the TV. Make sure to wipe the TV as gently as possible. TV screens are fragile and can be damaged when pressed too hard.Gently wipe the screen or the exterior with a dry, soft cloth, such as an eyeglass cleaner.

For inks from oil markers on the screen, soak a cloth in a non-soap synthetic cleanser diluted (by less than 1% ) with water. Squeeze the cloth tightly to eliminate excess liquid, then wipe gently to remove the ink. Use non-soap cleansers cautiously because it may cause environmental problems when disposed improperly.

At last count, I found a billion companies making TV screen cleaners. Almost all of these are something like 99 percent water, 1 percent other stuff. Years ago I tested a handful and found them, on average, to work well enough. If you don"t have luck with a simple cloth and possibly distilled water, a screen cleaner is worth a try, and as a bonus you can also use it for your laptop, tablet and cell phone screens. Plus, they come with a microfiber cloth. If they don"t clearly state they don"t contain alcohol and ammonia, however, I would skip them.

My advice? Get a nice microfiber cloth (if your TV didn"t come with one), and use that. If that doesn"t fix your smudges, try a cloth moist with water. Don"t press too hard. There"s less than a millimeter between your finger and a broken TV.

We asked a couple cleaning pros for the full rundown on how to clean TV screens of all types, including flat plasma and LCD screens, along with some common mistakes people make when cleaning their TV screens so you know exactly what to avoid.

Power down. Before breaking out any dust cloths or cleaners, make sure your TV is off. If you want to take an additional precaution, Cohoon says you can also unplug the TV, but it"s typically not necessary for modern TVs.

Dust the screen. Dry dusting your TV is a crucial step in the cleaning process. "Removing dry debris will ensure that you don"t accidentally create scratches by scrubbing a rough piece of dirt or buildup into the screen," Cohoon says. She recommends using a microfiber or soft cloth to gently dust the entire screen. If needed, flip the cloth over (or get a second cloth) in order to completely remove all dust, pet hair, and other loose debris. You can use a microfiber cloth to wipe down the speakers and cords as well.

Use screen-safe cleaner.Spray a small amount of screen-friendly cleaning product onto a soft cloth—never directly onto the screen itself—and wipe the TV down in a methodical, back-and-forth motion. Check that the cleanser is safe for the specific type of screen you are cleaning. Repeat as necessary to remove oily areas or fingerprint smudges. Also, don"t forget to gently wipe down the top and base of the TV.

Clean smudges on the screen."For tougher spots, make sure not to apply too much pressure, especially on more delicate screens," advises Leanne Stapf, the chief operating officer for The Cleaning Authority. "If microfiber cloth spot-cleaning doesn"t work, I recommend adding a bit of warm water to the cloth and then cleaning the spot with the dampened cloth."

Dust.Use a microfiber cloth to gently wipe away loose dust, dirt, or any other debris. You may need to turn the cloth over or get a second one to adequately remove everything.

Wipe down the screen."Since these screens are a bit sturdier, you can mix equal parts rubbing alcohol and lukewarm water to create a cleaning solution," Cohoon says. "Using a small amount of solution on a soft cloth, wipe the entire screen, base, and top." Spot-clean any stubborn areas with caked-on messes or heavy fingerprints. You can also remove fingerprints by rubbing with a microfiber cloth in a circular motion.

Scrubbing Too Hard:Modern TV screens are delicate and require a gentle touch. Wiping too vigorously or using a rough cloth can damage the screen quickly.

Spraying Solution Directly Onto the TV:All wet cleaners should be sprayed onto a cloth and then wiped over the TV. Spraying directly onto the screen can create spots that are hard to remove. It also puts you at risk of damaging the speakers.

Using Non-Approved Cleaners: Using store-bought glass cleaners on OLED or LCD TV screens is a big no-no. Stapf says, "These products contain harsh ingredients like alcohol and ammonia, which can damage the panels of the screen."

Start the remote control cleaning by removing the batteries. As with the TV screen recommendations, you’ll want to avoid spraying directly onto the surface, as this could cause the device to malfunction. Dampen a clean microfiber cloth and rub gently on the top and the underside of the remote control. For hard-to-reach gunk that’s jammed between the buttons, try a cotton swab dipped in a small amount of the cleaning solution. Make sure to let it dry thoroughly before replacing the batteries and using it again.

Williams likes TV cleaning kits for their ease of use. “A TV kit will be your safest option for cleaning a TV,” he says. “These kits will come with everything you need to get your TV looking new, like screen-cleaning solvent and a fast-drying microfiber cloth.” You can find TV cleaning kits and cleaning products designed for flat-screen TVs at electronics stores or on Amazon.

If you can picture the hulking tube TVs (also known as CRTVs) of yore, you may also remember how delightfully easy they were to clean—a few spritzes of window cleaner and some wipes with paper towels and you were good to go—no special microfiber cloth required. But modern TVs with fancier technologies like LCD, OLED, and plasma call for gentler techniques. “Avoid using chemicals like alcohol, ammonia or acetones when cleaning your TV. These cleaners were safe to use for previous generations of TVs with glass panels, but as the hardware changes with time, the cleaning methods do too,” says Williams. Since some multi-purpose and glass cleaners are made with ammonia, skip the Windex.

Modern TVs are often smart TVs but the cleaning tips are the same as the ones for LCD, OLED and plasma TVs. The microfiber cloth is your TV screen’s best friend. “The majority of TVs you purchase today will be smart TVs, and the cleaning process is the same as TVs without smart capabilities,” Williams says.

While you"ll find countless cleaning kits and specialty products marketed towards the flat-screen owner, most experts recommend using good old-fashioned water to clean your screen without damage. If your TV tends to collect lots of fingerprints, add about a teaspoon of isopropyl alcohol to a bowl of water to create your own homemade screen cleaner. Most rubbing alcohol is made from isopropyl alcohol, but always check the bottle before using this product to clean your TV. Some kinds of rubbing alcohol are actually made from ether alcohol, or ethanol, which isn"t the best choice for flat-screen televisions.

Whether you"re using an isopropyl alcohol blend or just plain water, keep in mind that you should never spray these materials directly onto the screen. Instead, dip a lint-free or microfiber cloth into your cleaning solution of choice, then wring it out until it"s just slightly damp. Many newer TVs come with an appropriate cleaning cloth, so check the box before you buy. You can also use a cloth designed for cleaning eyeglasses or camera lenses, as they"re made to clean without leaving lint or scratches behind. Wipe the screen very gently in smooth, even strokes to remove dust and other contaminants. Don"t apply excess pressure or scrub at your screen, as this could seriously damage your picture, and can even lead to dead or burnt-out pixels. When you"ve finished cleaning, carefully dry the screen using a soft, lint-free cloth. Never use a dirty cleaning cloth, as even tiny particles of dirt may become trapped in the fabric and can scratch your screen. While you may be tempted to use a clean paper towel, wood-based paper products are just too harsh for delicate flat-screens, and can leave behind ugly scratches that interfere with your viewing experience.

While many people use the terms "flat-screen" and "flat-panel" interchangeably, there are some significant differences between the two. Flat-screen refers to any TV with a curve-free screen, whether it"s a bulky cathode-ray unit or a sleek new LCD model. Flat-panel, on the other hand, refers to a TV with a flat, narrow body, and may include plasmas, LCDs and other advanced technology, but does not include classic cathode-ray units.

Flat screen monitors such as those found on your TV or computer are known as LCD monitors or high-definition flat-panel display. They"re very different from the screens found on old CRT or "tube" TV models. Those older models had thick glass which could easily be cleaned with window cleaner and a paper towel. Not so with an LCD or plasma screen. The LCD panel is made of specially designed flexible plastic and is very sensitive to chemicals. If you apply cleaners with chemicals in them, you may end up with a blank flat screen. Even using ordinary kitchen towels or paper towels may scratch the screen and leave lint.

Use a dry, soft cloth -- the kind you would use to clean your eyeglasses -- and very gently wipe the screen. If this doesn"t remove the oil or dirt, do not press down harder and try to remove the dirt. Pressing down on the screen will cause the pixels to burn out. Rather, proceed to the next step.

Make a solution of equal parts water and vinegar (or water with a tiny amount of dish soap). Dampen a cloth in the solution and gently wipe the screen. Again, rubbing and scrubbing will damage the screen.

It doesn"t hurt to wipe down the surface of your keys and your mouse at the same time you"re cleaning your screen, since many germs are housed on those surfaces. Using a dry microfiber cloth is always safest when it comes to removing dust.

Are there different considerations for cleaning a Mac screen versus a PC screen? In short, yes. We know that there are hundreds of different computer and monitor models to consider, but in general, screens are either backlit LED made with LCD (liquid-crystal display) pixels, or a non-LCD glass-coated surface. And just to note, some of the newer matte glass screens are nano-texture glass, which require a special polishing cloth from the manufacturer and should be cleaned with nothing else.

LCD screens are more susceptible to damage by cleaning agents, but because they’re commonly used on PC laptops and standalone computer monitors, there are lots of easy-to-use products available to clean them. It’s not that they’re hard to clean, but you’ll have to be careful and diligent so you don’t damage the surface or any of the LED elements. Any cleaners that include ammonia will leave a film. Soap and water can cause damage. It’s always safest and most effective to use an LCD cleaner free of alcohol, ammonia and acetone to clean an LCD screen, but if you need a DIY fix, you’ll be successful if you use a microfiber cloth that’s sprayed lightly with a mix of vinegar and distilled water.

Most Mac computer screens are glass-coated and can be cleaned and resolved streak-free more easily than LCD products using glass cleaners, like Windex, or a cloth lightly sprayed with rubbing alcohol. Nano-texture glass screens on products like the Apple Pro Display XDR or iMac require use of the special polishing cloth sold by Apple.

For fingerprints and smudges, spray 70% isopropyl alcohol onto a cloth, or use a pre-moistened alcohol wipe or a Clorox Disinfecting Wipe, to clean non-porous surfaces like the screen; do not use bleach.

To clean spots and streaks on the surface of the screen, mist an LCD cleaning spray onto a dust-free side of your microfiber cloth; an easy DIY solution is 1:1 parts of white vinegar and distilled water.

In the present invention, the pile of rubbing cloth material tilts at warp direction to the normal to a surface of cloth.The angle of inclination of this pile is preferably more than 5 ° below 45 ° with respect to the surface normal of cloth, more preferably more than 10 ° below 45 °.

The invention is characterized in,, be preferably shrinkage factor and be and (do ripe for 130～150 ℃) more than 10% or boiling water shrinkage (BWS) is synthon (dacron etc.) more than 8% as the synthon of highly shrinkable.In bottom line, use the advantage of the synthon of highly shrinkable, at first be by the thermal treatment bottom line after the system of knitting shrink can make organize closeer.Make the friction cloth that liquid crystal board is used,, produce the uneven possibility of friction owing to be related, so dense structure is better when between pile and the pile when gapped.Utilize this method, can form the dense tissue of knitting the system limit above loom.

In addition,, utilize thermal treatment that cloth is shunk, can increase the line density of the base fabric tissue of velveting, can reduce the elongation of relative organization"s tilted direction by using the high synthon that shrink in end warp and back weft line one or both.At this moment, the contraction of bottom line is influential to the inclination of pile.

In the cut-out of rubbing cloth material, to become the correct cut-out of desirable angle very important (with reference to No. 3155177 communique of Jap.P.) for warp.When the base fabric of rubbing cloth material is organized as solid color, be not easy correctly to set the cut-out angle of warp.At present, be to be that prerequisite is cut off with the right angle intersection with respect to warp with parallel, to wish crooked manyly yet on existing friction cloth, produce, this may be in every batch of grey cloth, the one of the main reasons of the LCD alignment characteristic changing after the friction.Therefore, the base fabric tissue of friction cloth, it is very important that the effect of employing temperature, humidity all is difficult to the material that is out of shape.In addition, in order easily to carry out the cut-out of correct significant angle, the part of the bottom line by will forming base fabric, the colo(u)r streak different with other bottom lines, put into the base fabric tissue at certain intervals, be to make one of preferred form that the cColor-cycling ground of base fabric tissue changes,, can use the black conductive synthon of rubbing into carbon dust as colo(u)r streak.

Using under the situation of hydrophobic synthetic fibre, can use base fabric and the pile that inweaves in the base fabric constitutes velveting under the fluffing state as rubbing cloth material.Pile is that long fibre or staple fibre are all passable.As the velvet tissue that in rubbing cloth material, uses, be generally the velveting (12: pile, 13: warp, 14: parallel) of fastening line pile shown in Figure 7.In addition, also can use the velveting (12: clipping, 13: warp, 14: parallel) that in pile, uses the V font pile (clipping) shown in Figure 8 of staple fibres such as cotton.In the present invention, in the warp and parallel or of these velveting base fabric tissues, use hydrophobic synthon, can obtain foregoing effect.

Secondly, the situation of melt process cloth end face is described.In this case, preferably will use the fiber of thermoplasticity such as dacron or hot melt property to make in the warp of base fabric tissue and in the parallel one or both.

Figure 12 for the direction of the end warp almost parallel of the velveting of knitting system by the tissue of Fig. 1 on the figure that makes with electron micrograph of cross section under the situation of normal temperature die cutting.Figure 13 is to the cross section under velveting fusion severing (melt process) situation identical with Figure 12, the figure that makes with electron micrograph.Specifically, Figure 12 and Figure 13 are based on after the normal temperature severing of rubbing cloth material of embodiment D1 described later and the electron micrograph of the end face after the fusion severing.

Melt process as the end face of rubbing cloth material has two modes preferably at least.A preferred form is the mode that heat is given the severing sword.Specifically, crush-cutting rubbing cloth material under the state of the temperature of rising severing sword, the end face of the fiber cut off of fusion thus, another preferably mode be to utilize the method for laser radiation.Specifically, utilize laser radiation to improve the temperature of tissue fibers, make fibers melt and severing.In addition, also have at normal temperatures the severing rubbing cloth material after, carry out the method for melt process as aftertreatment heating cutting surface.

The treatment temperature of melt process can suitably determine according to the kind of the bottom line of cloth, end fabric tissue, velvet head line.In the form that severing sword heat gives, in order to make line distortion and to cut off, usually its temperature preferably the fusing point with bottom line be the center in the scope of the low temperature of 50 ℃ high temperature to 20 ℃.In addition, in order to shorten break time, preferably the fusing point with bottom line is the center, in the scope of the low temperature of 15 ℃ high temperature to 10 ℃.In the form of laser radiation,, therefore do not need special design temperature owing to the direct fusion of cloth end face.

Under the situation of melt process cloth end face, as the warp and the parallel of the base fabric of rubbing cloth material, can use dacron, mekralon, polyamide fibre, polyvinyl chloride fibre, poly-inferior vinyl chloride fibers, vinylon fiber, fluorine fiber, aramid fibre etc.Particularly in the bottom, use thermoplasticity or hot melt property fiber to knit under the situation of system, utilize melt process that end face is melted, can reduce coming off of pile bits and bursting forth of warp or parallel.

In the rubbing cloth material (grey cloth) of above-mentioned tissue, utilize thermoplasticity or hot melt property fiber to constitute the base fabric parallel, if when cutting out or cut out after heat melt process end face, then can prevent coming off and bursting forth of pile fully by desirable size.

Velvet cloth compound is become with respect to 0 ° of the one-tenth of warp, and 5 °, 10 °, 15 °, 30 °, 45 cuts into wide 5cm, long 30cm makes test film.Under the situation of the drawing stress that adds 5kg on each test film, from each angle of the warp of each cloth, the elongation under expression standard state and the sucting wet state.Measure according to this, know the elongation dependence and the anisotropy of humidity (particularly to) of base fabric tissue.In table 1, implement A1 and A2 test portion tissue and the cuprammonium rayon of use Fig. 7 velvet organize identical.In addition, the test portion of embodiment A 1 and A2 all uses 84 dtex Triafol Ts in pile, uses the polyester of 110 dtexs in end warp.The length of pile is 1.8mm.In addition, the test portion of embodiment A 1 uses the polyester of 84 dtexs, the test portion of embodiment A 2 to use boiling water shrinkage to be about the high retract line of the polyester of 35% 84 dtexs in the back weft line in bottom line; Be coated with resin overleaf based on acrylic resin.

The test portion of Comparative examples A 1 uses cloth to use the rayon velvet of the cuprammonium rayon of market sale in bottom line as existing liquid crystal friction.

As a result, under standard state, for the elongation of the stress of 5kg/5cm, the angle of warp is 10 ° relatively, and embodiment A 1 and A2 and Comparative examples A 1 do not have big difference.When surpassing 15 °, significant difference obviously appears between embodiment A 1 and Comparative examples A 1 more.Elongation under the sucting wet state, the elongation of the embodiment A 1 of use dacron is lacked than the Comparative examples A 1 of using cuprammonium rayon significantly in bottom line.In all cases, demonstrate the test portion that in parallel, uses the embodiment A 2 of high retract line, than the difficult elongation of the test portion of embodiment A 1.Therefore, as the dimensional stability of rubbing cloth material, in embodiment A 1 and A2 and Comparative examples A 1, be preferably embodiment A 2＞embodiment A 1＞Comparative examples A 1 successively.

Table 2 is the angle of inclination (organizing the angle of vertical direction for base fabric) of the pile that utilizes velvet of the present invention and knit the system of the knitting condition of the velvet that pile that system tissue makes rubbing cloth material tilts and observe on opposite length direction.

After knitting system,, utilize common manufacturing procedures such as removing paste is purified, xeothermic, back side process of resin to carry out finishing, obtain rubbing cloth material velvet cloth 150 ℃ of down setting.

The level of the generation static of comparative evaluation rubbing cloth material of the present invention at first, is under 60% the state, with the alignment film of various friction cloth friction liquid crystal in humidity.At this moment, approach (d among Fig. 5) is 0.5mm, utilizes mensuration with voltage, the static content that produces on roller when estimating friction.

The material of embodiment A 9 is identical with embodiment A 8 in the back side of the test portion of embodiment A 7, and the electroconductive resin back of the body of sneaking into carbon particle (powder) in resin pastes processing.In the test portion of this embodiment A 9, the most pronounced effects of reduction with voltage, like this, static can more promptly be emitted to above-mentioned electroconductive resin, therefore can be from the whole discharge in the back side of rubbing cloth material.In addition, because the base fabric of the test portion of embodiment A 7 organizes length direction to have black muscle to expose, therefore cut off the size that is attached on the roller easily (promptly; Determine cutting direction easily).Use other advantages of dacron and the high retract line of polyester to be in bottom line, utilize the severing of the hot sword (～250 ℃) of base fabric tissue to carry out easily, section is bonding voluntarily not to need aftertreatment.

By in the parallel of base fabric tissue, using high (synthesizing) fiber that shrinks to knit the grey cloth of system, under the state of the distortion of restraining Width (weft direction), carry out dry heat treatment, can reduce the inclination of parallel, below this point of explanation.

The system of knitting test portion to embodiment A 10 and reference example A1 carries out under 150 ℃ 5 minutes heat treated.Embodiment A 10, contraction is limited in 5% with interior state under, handle to have the test portion that 12.3% character of shrinking is arranged under free state on the cloth Width.In reference example A1, produce this contraction hardly.Here, the degree of crook with parallel is following such definition as oblique value Z.That is: with reference to Fig. 6 (a), Fig. 6 (b), the height Y that parallel is entered in the degree of crook up and down of parallel of warp per unit length X is defined as oblique value Z

As described below, under the system of the knitting condition shown in the table 5, make rubbing cloth material of the present invention, measure its pile angle of inclination (organizing the angle of vertical direction for base fabric).

In the rubbing cloth material of the Embodiment B 1～B4 that makes under the above system of knitting condition, measure each pile angle of inclination, the result is as shown in table 5.Only can find out and just can obtain different pile angles of inclination by working hard from these results in the system condition of knitting.About the angle of inclination, measure for the base fabric surface normal for the warp direction inclination angle.Specifically, the principal element at decision angle of inclination is the sendout of end warp and the Tension Difference of warp of the resultant end.The density of the thickness of bottom line, back weft line (because the thickness back weft line density of parallel has the upper limit).By controlling these, the fabric at thus can be usually identical with the system of stably knitting repeatedly pile angle of inclination.

Now utilize the discovery situation of the vertical muscle of method evaluation friction shown in Figure 5, that is: the rubbing cloth material of Embodiment B 1～B4 is wrapped on the friction roller 1 of stainless steel of Φ 50mm with the double-sided adhesive band respectively, on the square glass substrate of 10cm, printing coating polyimide precursor solution.To adhere to 200～300 ℃ down the glass substrates 5 of the polyimide system alignment film made of heating be fixed on the transfer table 6, getting approach d is 0.5mm, moves transfer table 6 with the speed of 30mm/ second in the direction of arrow, rubs.The rotation number of friction roller 1 is 1500rpm.As a result, all rubbing cloth materials all obtain the vertical few even alignment film of muscle.

As described below, as velvet head line, use triacetate or dacron, or use high retract line as the few end warp of sendout, make rubbing cloth material of the present invention, measure its pile angle of inclination.

In Embodiment B 5, the polyester two-wire that uses 56 dtexs is as end warp, is under 100 the situation at the line length of fetching and delivering the few warp of output, and the line length of the warp that sendout is many is 280 to knit system.At this moment tension force, the former is 104～110g, the latter is 65～70g.The triacetate two-wire that uses 84 dtexs is as velvet head line.After knitting system,, purify by removing paste 150 ℃ of down setting, common manufacturing procedure such as xeothermic, back side process of resin carries out finishing, obtains rubbing cloth material (velvet cloth).

In Embodiment B 6, (boiling water shrinkage is 35% to use the high-contraction polyester two-wire of 56 dtexs, JISL-1013) as the few bottom line line of sendout, use the polyester two-wire that shrinks few 56 common dtexs as the many end warps of sendout, be under 100 the situation in the former line sendout, the latter is 120, and the tension force both when knitting system is 100g～110g, much at one.Use the triacetate two-wire of 84 dtexs to be velvet head line.After knitting system, 150 ℃ of following dry heat treatment 5 minutes.When carrying out this thermal treatment, 12% over feed rate(OFR) (overfeed) is arranged on the cloth length direction, after obtaining 2% width on the Width, utilize common manufacturing procedure to carry out finishing and obtain rubbing cloth material.In Embodiment B 6, by being heat-treated, the high polyester two-wire that shrinks shrinks the ratio that changes line length, and make pile have the angle of inclination.

In Embodiment B 7, except the polyester that in pile, uses 84 dtexs, also make rubbing cloth material according to the operation identical with Embodiment B 5.

With regard to the pile of the rubbing cloth material of the Embodiment B 5～B7 of above such making, measure the angle of inclination.Measurement result is as shown in table 6.Can find out from these results, raw material and the natural fiber measured, all it doesn"t matter for synthon, semisynthetic fibre, confirm and can obtain stable inclination this point, in addition, in Embodiment B 6, can obtain making the identical effect of situation of the positive change sendout of cloth contraction with using high-shrinkage fibre.

As described below, be manufactured on the rubbing cloth material of the present invention (velveting) that uses dacron, nylon fiber, mekralon in the bottom line, measure its elongation.These pile fabrics all are the systems of knitting with fabric tissue shown in Figure 7.

In Embodiment C 1, the twist was 900T.P.M under warp used in the dacron of 56 dtexs at the bottom of the operation.The doubling twisting of last twist 600T.P.M; Use the dacron of 84 dtexs as the back weft line, the density of end warp is 23/cm, and the density of back weft line is 44.5/cm.Use the triacetate processing line of the two-wire of 84 dtexs as velvet head line.Knitting making herbs into wool head length degree is the velveting of 1.8mm, carries out finishing with common job operation, there not being the side coating acrylic resin of pile, obtains rubbing cloth material.

In Embodiment C 2,, use the nylon fiber of 56 dtexs as the back weft line as the doubling twisting of end warp twist 600T.P.M on following twist 900T.P.M in the nylon fiber line at 56 dtexs.End warp density is that 23/cm, back weft line density are 52/cm.Knit making herbs into wool length as velvet head line and be the velveting of 1.8mm, carry out finishing with common job operation, do not having a side of pile cloth, the coating acrylic resin obtains rubbing cloth material.

In Embodiment C 3, warp uses the doubling twisting that descends twist 450T.P.M on the twist 750T.P.M in the line of mekralon 56 dtexs as the back weft line at the bottom of the operation, uses 56 minutes mekralon as the back weft line.End warp density is 23/cm, and the back weft line density is 45/cm.Use the triacetate processing line of 84 dtexs as velvet head line.Knitting making herbs into wool head length degree is the velveting of 1.8mm, carries out finishing with common job operation, and in cloth one side that does not have pile, the coating acrylic resin obtains rubbing cloth material.

In comparative example C1, use the present liquid crystal friction cloth of velveting conduct of the rayon pile of market sale.This kind velveting uses the viscose rayon yarn of 84 dtexs in end warp; In the back weft line, use the cuprammonium rayon of 66 dtexs.

In the rubbing cloth material of above Embodiment C 1～C3 that draws like this and comparative example C1, the pile and the end, dispose through line parallel.Alignment film is being carried out under the situation of friction treatment, prior art is, the sense of rotation of the roller that preferably rubs and the base fabric of rubbing cloth material be 3～45 ° (No. 3209328 communique of Jap.P.) of skew through the suede angulation.

In the rubbing cloth material of Embodiment C 1～C3 and comparative example C1, become the direction of 150 ° of angles to cut off at warp direction with relative warp, obtain wide 5cm, the test film of long 30cm, when cutting off, the cloth of Embodiment C 1～C3 and comparative example C1 cloth relatively can cut off accurately.For each test film, under standard state and sucting wet state, give the drawing stress of 5kg, measure elongation at this moment, by measuring, draw the elongation dependence and the anisotropy of humidity (particularly to) of base fabric tissue.Measurement result is as shown in table 7.

At first, make the rubbing cloth material that the fabric tissue by Fig. 7 constitutes.The doubling twisting two-wire of dacron that uses 56 dtexs is as end warp, and the polyester that utilizes 56 dtexs is as the back weft line, and the triacetate two-wire that utilizes 84 dtexs is knitted the throwing pile fabric as velvet head line.The density of end warp is 23/cm, and the density of back weft line is 45/cm.Be coated with acrylic resin in cloth one side that does not have pile, obtain rubbing cloth material, secondly, use the severing sword identical with embodiment D1, produce heat to well heater energising, with end warp almost parallel with depart from the direction of 15 ° of the end warps fusion severing rubbing cloth material, at this moment, the temperature of blade tip end is 245 ± 25 ℃

The rubbing cloth material that making is made of the fabric tissue of Fig. 7.As end warp and back weft line, at nylon fiber (nylon 6) with 56 dtexs (17 threads), end warp uses the twist 900 commentaries on classics/m down, the doubling twisting of the last twist 600 commentaries on classics/m, end warp density is 23/cm, the back weft line density is 47.5/cm, uses the triacetate two-wire of 84 dtexs as velvet head line.Knit the throwing pile fabric, carry out finishing, obtain rubbing cloth material with common job operation.Secondly, uses the severing sword identical with embodiment D1, to well heater energising produce hot, with end warp almost parallel and the direction that departs from 15 ° of end warps on fusion severing rubbing cloth material.At this moment, the temperature of blade tip is 210 ± 5 ℃.

At first, make the rubbing cloth material that the fabric tissue by Fig. 7 constitutes.As end warp and back weft line, use the mekralon of 56 dtexs (24 threads), end warp conduct is the twist 750 commentaries on classics/m down, the doubling twisting of the last twist 450 commentaries on classics/m uses, and end warp density is 23/cm, and the back weft line density is 42/m, use three acetic acid two-wires of 84 dtexs as velvet head line, knit the throwing pile fabric, utilize common job operation to carry out finishing, obtain rubbing cloth material.Secondly, uses the severing sword identical with embodiment D1, to well heater energising produce hot, with end warp almost parallel and the direction that departs from 15 ° of end warps on fusion severing rubbing cloth material.This moment, the temperature of blade tip was 160 ± 5 ℃.

At first, prepare the rubbing cloth material of the cotton of the market sale that the fabric by Fig. 8 constitutes.The end warp of these market sale product, back weft line and velvet head line all are made of No. 40 two-wires of cotton.Pile length is 2.5mm.The back side of this cloth is resinous coat with vinyl acetate.Secondly, prepare the Thomson sword made by the steel of Na カ ヤ マ Co., Ltd. system, with the direction of 15 ° of end warp almost parallel and irrelevance warps on use the die cutting rubbing cloth material.At this moment blade tip temperature is a normal temperature.

Evaluation utilizes the rubbing cloth material end face of velvet cloth friction severing, the situation that visual pile comes off in embodiment D1～D4 and Comparative Example D 1.

In the rubbing cloth material that carries out the disconnected embodiment D1～D4 of fusion, with the fusion severing of warp almost parallel ground, the end with depart from fusion severing on 15 ° of directions of warp,, nearly all cannot see pile and come off owing to the bottom line melting deformation.

Relative therewith, in the rubbing cloth material of the Comparative Example D 1 of carrying out the normal temperature die cutting, because the warp and the parallel of base fabric are not whole fusions, the root of pile utilizes is resin-coatedly knitting fixedly base fabric of the system tissue and the cloth back side, but causing by die cutting on the part of base fabric disorganization, the pile root is fixing insecure, therefore roughly blocking abreast and departing from severing on the direction of 15 ° of end warps with end warp, can see that all pile comes off more, therefore, utilize the rubbing cloth material of Comparative Example D 1, the friction LCD alignment film the time, pile may come off.

No matter where LCD screens are kept, they will always need cleaning from time to time. Cleaning an LCD may seem like a daunting task, but there are a few simple ways to clean it without damaging to scratching to surface.

It is recommended to use a simple alcohol solution to clean an LCD screen. This solution is made up of part distilled water and part 50% isopropyl alcohol. Be warned that isopropyl alcohol is flammable.

Do NOT use tissues/Kleenex to wipe your screen. That is ineffective, because they will leave little tissue particles all over your screen. You want a 100%-cotton cloth that is soft and absorbent. A t-shirt is a good cloth, but so is a sock or a Turkish towel, so long as it is 100% cotton.

Stay away from cloth that has polyester in it because this can contain stiff filaments. These filaments can scratch the screen while you are rubbing over it. Also stay away from paper towel and tissues. While it might feel soft, remember that it is paper and therefore, it comes from wood. This means that there might be microscopic wood fragments in the paper towel that will scratch your screen if you move it over it. Therefore, avoid anything paper and instead, focus on the cotton.

First dampen the cloth with the alcohol solution. You should never spray any sort of liquid directly onto the screen. You also don’t want to try and clean the screen without some sort of liquid because the dust particle, as it is moved across the screen, will scratch.

Be careful not to let the cleaning solution leak into the sides of the monitor. Also, be certain that you do not press hard on the LCD screen. You can permanently damage an LCD screen by pressing on it too hard.

If there is just dust on your screen, there is no need to fully clean it. To remove dust all that must be done is to wipe it away with a microfiber cloth. Simply wipe your screen from end to end gently with the cloth.
