The woven fabric refers to a fabric formed by interweaving warp yarns and weft yarns vertically, and the basic weave of the woven fabric is plain, twill or satin. A knitted fabric is produced by knitting a yarn or a filament into a loop by a knitting needle, and then interlooping the loops. Due to the structural characteristics of the loops of the knitted fabric, the yarn storage amount in unit length is large, so the knitted fabric has good elasticity. However, knitted fabrics are easily deformed and are easily curled and crimped at high temperatures.
