Warp density

——The length direction of the fabric; the yarn in this direction is called the warp; the number of yarns arranged within 1 inch is the warp density (warp density);

Weft density

——The width direction of the fabric; the yarn in this direction is called the weft, and the number of yarns arranged within 1 inch is the weft density (weft density);

density

——Used to indicate the number of yarns per unit length of woven fabrics, generally the number of yarns within 1 inch or 10 cm. The Chinese national standard stipulates that the number of yarns within 10 cm is used to indicate the density. Textile companies are still used to expressing density by the number of yarns within an inch. As commonly seen, "45X45/108X58" means that the warp and weft yarns are 45, respectively, and the warp and weft densities are 108 and 58.

Width

——The effective width of fabrics is generally expressed in inches or centimeters. Common ones are 36 inches, 44 inches, 56-60 inches, etc., which are called narrow width, medium width and wide width respectively. Fabrics higher than 60 inches are Extra-wide fabrics are generally called wide-width fabrics. Today, the width of extra-wide fabrics in China can reach 360 cm. The width is generally marked behind the density, such as: If the fabric mentioned in 3 is added with the width, it will be expressed as: "45X45/108X58/60"", that is, the width is 60 inches.

Gram weight

——The gram weight of the fabric is generally the gram weight of the square meter fabric, and the gram weight is an important technical indicator of knitted fabrics. The gram weight of denim fabrics is generally expressed in "ounces (OZ)", that is, the number of ounces of fabric weight per square yard, such as 7 ounces, 12 ounces of denim, etc.;

yarn-dyed

——In Japan, it is called "dyed fabric first", which refers to the process of first dyeing yarn or filament, and then using dyed yarn for weaving. This kind of fabric is called "dyed fabric" and produces yarn-dyed fabric. Cloth factories are generally called dyeing and weaving factories, such as denim, and most shirting fabrics are yarn-dyed.
