Textiles can be divided according to textile processing […]
Textiles can be divided according to textile processing materials: cotton spinning, silk processing, linen spinning, woolen chemical fiber; also according to the weaving method: knitting, woven, non-woven; chemical processing exists in each process, but the most chemical processing is chemical Fiber industry and dyeing and finishing industry.
1. Warp direction, warp yarn, warp yarn density-the length direction of the fabric; this direction yarn is called warp yarn; the number of yarns arranged within 1 inch is warp density (warp yarn density);
2. Weft direction, weft yarn, weft yarn density-the width direction of the fabric; this yarn is called weft yarn, and the number of yarns arranged within 1 inch is the weft density (weft yarn density);
3. 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. Our national standard stipulates that the number of yarns within 10 cm is used to indicate the density, but Textile companies are still accustomed to use the number of yarns within 1 inch to express density. For example, the commonly seen "45X45/108X58" means 45 warp and weft respectively, and the warp and weft density is 108 and 58.
4. Width—The effective width of the fabric is generally expressed in inches or centimeters. Common ones are 36 inches, 44 inches, 56-60 inches, etc., which are called narrow, medium and wide, respectively, higher than 60 Inch fabrics are extra wide, usually called wide fabrics. Today, the width of extra wide fabrics in our country can reach 360 cm. The width is generally marked after the density. For example, if the width of the fabric mentioned in 3 is added, it will be expressed as: "45X45/108X58/60"" which means the width is 60 inches.
5. Gram weight-the gram weight of the fabric is generally the gram of the fabric weight in square meters. The gram weight is an important technical indicator of knitted fabrics. Woolen woolen cloth usually also takes gram 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.;
6. Yarn-dyed fabric-called "first dyed fabric" in Japan, it refers to the process of dyeing yarn or filament first, and then using dyed yarn for weaving. This kind of fabric is called "dyed fabric" to produce dyed fabric. Weaving factories are generally called dyeing and weaving factories, such as denim, and most of the shirt fabrics are yarn-dyed fabrics
