An optimal technical scheme of the present invention is that every pile yams is woven into via a warp thread, V-shaped.
The present invention is in order to address the above problem, and making the yarn diameter of the warp thread of the base fabric silvalin that forms friction cloth was 50～80 dawnNeil is to increase ultimate fibre radical. That is to say, because the fibre diameter of warp thread is thin, can increase the root of the pile yams inweavingNumber, consequently, can increase the ultimate fibre radical of the pile of per unit area. In this friction cloth, by the list of pile yamsFibre number is scaled 1.5 dtexs (デ シ マ ッ Network ス), and ultimate fibre radical is 80000/cm2Above.
And in the present invention, the yarn that forms base fabric adopts the polyester fiber as high-shrinkage yarn with pressing suede yarn, and grey cloth is stoodHigh temperature, so that base fabric, float shrink, increases pile density.
When the shrinkage factor of particularly considering warp thread, weft yarn is made into grey cloth, can obtain the stay in grade that between-lot quality fluctuation is littleThe friction cloth used of manufacture LCD.
In the present invention, base fabric, pressure suede yarn adopt polyester fiber, and pile adopts cotton fiber, the friction cloth that manufacture LCD usesThe diameter of the warp thread of base fabric is 50～80 daniers. And because base fabric, pressure suede yarn adopt high-shrinkage yarn, can increase every listThe ultimate fibre radical that plane is long-pending. Adopt LCD of the present invention to manufacture with friction cloth, can with high finished product rate provide high-quality,There is the LCD display unit of picture element density more than 300dpi.
