The twill is that the warp and weft yarns are interlaced at least once, that is, 2 times up or down 3 times. The twill fabric is modified by adding warp and weft interlacing points, which are collectively referred to as twill fabrics. The characteristics of this kind of cloth are relatively thick, and the stereoscopic feeling of the tissue is strong, and the number of branches is 40 and 60.
The twill fabric is better recognized because the interlaced points of the warp and weft of the twill fabric form a certain angle of the twill line structure on the surface of the fabric. Its characteristics are that there are positive and negative points, fewer interlacing points, longer floating lines, softer feel, higher density, thicker products and stronger stereoscopic structure.
