A fabric woven with a twill weave structure, in which the warp and weft yarns are interlaced at least once every two yarns during the weaving process, i. E. 2 up and 1 down or 3 up and 1 down; The interweaving of warp and weft yarns forms oblique patterns, and the weaving method is to increase the interlacing points of warp and weft, which are continuous and change the fabric structure layout. The number of interweaving of warp and weft yarns is less than that of plain weave, and the arrangement of yarns is closer, resulting in a tighter and thicker texture than plain weave fabrics.

Twill fabric is easier to identify because the interweaving points of warp and weft lines on the fabric surface present a certain angle of diagonal line structure. Its characteristics are divided into front and back, with fewer interweaving points, longer float lines, slightly rough touch, high density, thick product, and strong three-dimensional organization. The number of branches varies from 30, 40, to 60.

Its characteristics are divided into front and back, with fewer interweaving points, longer float lines, a soft touch, higher density, thicker products, and stronger three-dimensional organization.
