The twill fabric is a second twill, 45 left sloping cotton fabric. The positive twill lines are obvious, and the negative side of the variegated twill is not obvious. The warp and weft count is close, the warp density is slightly higher than the weft density, the feel is softer than the khaki.
Twill fabrics are divided into coarse twill and fine twill. The coarse twill fabric uses the cotton yarn with more than 32 ( below 18 British branches ) cotton yarn as warp and weft yarn; Fine twill fabrics uses cotton yarn with less than 18 ( over 32 British ) as warp and weft. Twill is raw white, blanch, and variegated, often used as a uniform, athletic wear, inner-lining of sports shoes, carborundum cloth backing and spacer. Wide blanch twill can be used as the bed sheet, and can be used as a sheet after printing. The primary color and variegated fabrics are light on the surface of the cloth after the electro-optic or rolling finishing, and can be used as the umbrella fabric and a clothing inner-lining.
The basic feature of the twill fabric is to use various twill fabric to show the warp or weft length of the fabric. Twill fabrics belong to the low-end twill cotton cloth, which has coarse and fine (20 - 40 branches) with 2 / 1 left twill weave. Its texture is slightly thicker and softer than plain cloth, with clear lines.
