Density of textiles.

Density-used to indicate the number of yarns per unit length of woven fabric, usually 1 inch or10cm. China's national standard stipulates that the density is expressed by the yarn count within 10 cm, but textile enterprises are still used to expressing the density by the yarn count within 1 inch. Among them, it is divided into warp density and weft density.

A. warp density-the length direction of the fabric; The yarn in this direction is called warp; The number of yarn arrangements within 1 inch is warp density (warp density);

B. Weft density-the width direction of the fabric; This directional yarn is called weft, and the number of yarns arranged within 1 inch is weft density (weft density); For example, the common "40X40/ 1 10X90" in hotel linen indicates that there are 40 warp yarns and 40 weft yarns, and the warp and weft densities are 1 10 and 90 respectively. ?
