- the width direction of the fabric; the yarn is referred to as the weft yarn, and the number of the yarns in the 1 inch is the weft density (weft density);
——Used to indicate the number of yarns per unit length of the woven fabric, generally the number of yarns within 1 inch or 10 cm. The national standard stipulates the density of the yarn within 10 cm, but the textile enterprise still It is customary to use the number of yarns within 1 inch to indicate density. As commonly seen, "45X45/108X58" means that the warp weft yarns are respectively 45 pieces, and the warp and weft density is 108, 58.

Extra wide, commonly referred to as wide-width cloth, today's extra-wide fabrics can reach a width of 360 cm. The width is generally marked behind the density, such as the fabric mentioned in 3, if the width is added, it means: "45X45/108X58/60"" is 60 inches wide.
——The weight of the fabric is generally the weight of the square fabric weight. The weight is an important technical index of the knitted fabric. The woollen wool usually also takes the weight as an important technical indicator. The weight of denim fabric is generally expressed in "ounces (OZ)", that is, the number of ounces per square yard of fabric weight, such as 7 ounces, 12 ounces of denim, etc.;
