Twill fabric is made of cotton. Twill fabric is a cotton fabric with a diagonal pattern of two upper and lower layers and a 45 ° left diagonal. The front twill pattern is obvious, while the back of the variegated twill fabric is not very obvious. The number of warp and weft yarns is similar, and the warp density is slightly higher than the weft density, resulting in a softer texture than khaki.

There are two types: coarse twill and fine twill. Coarse twill fabric uses cotton yarn of size 32 or above as warp and weft yarns; Fine twill fabric uses cotton yarn of size 18 or below as warp and weft yarns.

There are various types of twill fabric, including natural white, bleached, and variegated, commonly used as lining for uniforms, sportswear, and sports shoes, as well as diamond sanding and lining materials.

Wide width bleached twill fabric can be used as bedding, and after printing and processing, it can also be used as bed sheets. Yuan color and variegated fine twill fabrics have a shiny surface after being electropolished or calendered, and can be used as umbrella surfaces and clothing clips. Nylon polyester herringbone twill fabric is a rising star in the field of blended fabrics, and is also one of the popular conventional blended fabric fabrics.
