Summary of the invention
Technical matters
Inhomogeneous if rub, the distribution of liquid crystal molecule becomes inhomogeneous so, and part difference or possibility are owing to the cut on the alignment layer surface produces line to such an extent as to optical characteristics may become.
The revolution of fraction time, friction depth, roller, the radius of roller, the translational speed of platform etc. are depended in the success of friction process.These process conditions are set by liquid crystal display manufacturer and malleable not.Therefore, the important variable factor in friction process is the length, intensity, thickness, density of friction cloth napping etc.Yet, because the hair yarn that rises of traditional friction cloth mainly made by rayon, to such an extent as to just be easy to produce cut if the too high frictional strength of intensity is inhomogeneous.Also because the change of rayon yarn thickness is limited and the improvement of cashmere density also is limited, so be difficult to form the groove of good orientation.And, also because of instability when rayon contacts with water, the complexity and expensive so manufacture process becomes.
Cellulose acetate (after this only being called acetate) fiber also has been widely used for hair yarn.Yet, because 2.5 hydroxy functional groups of each cellulosic molecule are replaced by acetyl functional group, thus the wettability power reduction, to such an extent as to may produce as problems such as static, low fiber stiffness.Therefore, it is not suitable for the friction cloth of liquid crystal display.
Technical scheme
One aspect of the present invention provides a kind of friction cloth that is used for liquid crystal display, it is compared with traditional rayon has superior directionality, extensibility and storage characteristics and by using the rise hair yarn of modification acetate fiber as the cloth that rubs, can form the groove of even and good orientation and the problem of solution cut and inhomogeneous friction; And manufacture method.
Another aspect of the present invention provides a kind of liquid crystal display that utilizes friction cloth to make.
The best mode that carries out an invention
The invention provides a kind of friction cloth that is used for liquid crystal display; it comprises the fabric of warp thread and weft yarn and has the hair yarn that rises along warp thread or weft direction inclination angle orientation, wherein this to play hair yarn be the modification cellulose acetate filament fiber that the 10-50% of wherein all acetyl group functional groups is replaced by hydroxy functional group.
The present invention also provides a kind of manufacture method that is used for the friction cloth of liquid crystal display, and it may further comprise the steps:
A) between two fabrics, weave the cellulose acetate long filament to have made hair yarn;
B) cut off fine hair between this fabric;
C) will play hair yarn and be modified to alkaline state, so that the 10-50% saponification of all acetyl group functional groups of acetate fiber is to hydroxy functional group;
D) napping, scratch brushing, grinding and process of resin should the alkalescence modifications plays hair yarn, so that it is along the direction orientation of the warp thread of fabric or weft yarn or have an inclination angle; And
E) coating or laminated fabric are with the hair yarn that rises of fixed orientation.
The present invention also comprises the liquid crystal display that utilizes this friction cloth to make.
Hereinafter, the present invention is described in more detail.
The deacylation of acetate fiber (being called " saponification " below) utilizes alkali or acid to implement.When acetate fiber utilized alkali soap, saponification took place to internal layer gradually from the skin of fiber.Therefore, can obtain the selectivity saponification by control rate.Thus, fiber can have the rayon feature at skin and have the acetate feature at internal layer.
If the inventor finds to utilize playing many cellulose acetate long filaments of hair yarn braiding and with the surface of alkali modification cellulose acetate, can forming the groove of good orientation so and can solve as problems such as cut, inhomogeneous frictions in friction process of friction cloth that liquid crystal display uses.
Friction cloth of the present invention is made by following: weave many cellulose acetate long filaments as playing hair yarn between two fabrics of warp thread and weft yarn along the warp thread direction that plays hair yarn, with alkali modification cellulose acetate filament surface and made hair yarn along the direction of warp thread or weft yarn orientation and have parallel rake, obtain evenly distribution like this.
Preferably, the present invention rubs cloth along the direction braiding that increases cashmere density, to form the groove of good orientation.Therefore, preferably use the viscosity rayon long filament of 50-200 Denier or cuprammonium (cuprammonium) rayon to be used for fabric (base fabric).
Also preferably, the cellulose acetate long filament with the 50-240 Denier has been used for hair yarn.
Preferably, the cellulose acetate filament fiber has the degree of substitution of 2.0-2.75.
Play hair yarn and have every 1cm
2At least 24,000 filament density.
The hair yarn that rises that preferably, will weave between two fabrics cuts off so that villus length becomes 1.4-2.1mm.
Preferably, after cutting off fine hair, the acetate fiber of every 100wt% uses the alkali of 5-20wt%.If the content of alkali is lower than 5wt%, outer layer of cellulose does not have the rayon characteristic so, and owing to static, low fibre strength etc., the formation that is used for liquid crystal display orientation groove becomes difficult like this.In addition, if surpass 20wt%, even internal layer has the rayon feature, thereby do not have problems such as static, low fibre strength, but worsen the feasible uniform napping that is difficult to obtain at water stability.For alkali, the preferred reaction solution that uses water miscible aqueous slkali separately or mix acquisition by water miscible aqueous slkali with reaction promoter.
Through using alkali modification, the cellulose acetate filament fiber has the saponification degree of 10-50%.That is, the acetate fiber alkali modification of 2.0-2.75 degree of substitution is arranged, so that the 10-50% of all acetyl group of acetate fiber, preferred 20-40% is by the hydroxyl saponification.As a result, acetate fiber has the degree of substitution of 1.27-1.91.If the saponification degree of acetate fiber is lower than 10%, fibrous outer does not have the rayon characteristic so, to such an extent as to because the orientation groove of formation liquid crystal displays such as static, low fibre strength becomes difficult.In addition, if surpass 50%, even internal layer has the rayon feature.Therefore there are not problems such as static, low fibre strength, to such an extent as to but the stability that has reduced in water is difficult to obtain uniform fine hair.
For alkali cpd, can use alkali metal hydroxide, as the alkaline earth metal hydroxide of calcium hydroxide, as alkali carbonate of sodium carbonate etc. as NaOH.
The aqueous solution of alkali can comprise compatible with alkali and the reaction promoter energy controls reaction speed.Preferably, the reaction promoter that contains 0.001-2.0wt%.The example of commercially available reaction promoter is Neorate NCB (Hankook Fine Chemicals), it is a kind of compound based on , and KF Neorate NA-40 (Hankook Fine Chemicals) and Snogen PDS (Dae YoungChemical), it is a quaternary ammonium compound.
With alkali modification play hair yarn napping, scratch brushing, grinding and process of resin so that fabric along warp thread and weft direction orientation and have certain inclination angle.
In order to have made warp thread and the weft direction orientation of hair yarn along fabric, the warp thread direction along fabric on the stenter of the roll brush of being furnished with difformity and type moves the pile of saponification simultaneously with its scratch brushing.The size of the friction cloth that foundation will be used and purpose are along warp thread and weft direction roll brush.Fine hair is tilted to make it become the angle of 5-40 degree with the benchmark perpendicular line on the fabric.If the fine hair inclination angle may produce cut less than 5 degree in alignment films.In addition, if the inclination angle surpasses 40 degree, can not form the orientation groove fully.During scratch brushing technology, can be with anti-shrinking medium, be impregnated in the face fibre to have improved the mechanical stability of hair yarn based on plastifier of siloxane etc.In such processing, the kind of adjuvant and concentration can change according to purpose.Adjuvant is not particularly limited, as long as it is just passable to have improved the mechanical stability of hair yarn.
In order to prevent to break away from and adhere on the alignment films from fabric playing hair yarn during the orientation process, the inner fabrics of face fibre adopts smears coating or lamination.For the smears, can adopt at least a of following resin: polyurethane, polyvinyl acetate, polyacrylate (polyacryl), polyamide, polyimide, polyester and polyureas.If the coating of inner fabrics is too thick, friction cloth does not closely adhere on the friction roller, will make friction become inhomogeneous.In addition,, may come off and adhere on the alignment films from fabric in napping during the orientation process so, cause inadequate friction if coating is too thin.Therefore, preferred coating weight is 10-100g/m
2
As above-mentioned, during the friction process of friction cloth of the present invention at liquid crystal display of the simple modification of peracetic acid napping yarn, can form good orientation groove, and can solve the problem of cut and inhomogeneous friction.Therefore, the present invention can provide a kind of liquid crystal display with optical characteristics of obvious raising.
