1. Warp density
The length direction of the fabric; the yarn in this direction is called the warp yarn; the number of yarns arranged within 1 inch is the warp density (warp density);
2. 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);
It is used to indicate the number of yarns per unit length of woven fabric, generally the number of yarns within 1 inch or 10 cm. Chinese national standards stipulate that the number of yarns within 10 cm is used to indicate density, but textile companies still It is customary to use the number of yarns within 1 inch to express density. For example, the commonly seen "45X45/108X58" means that the warp and weft yarns are 45 respectively, and the warp and weft density is 108 and 58.
The effective width of the fabric is usually expressed in inches or centimeters. Common ones are 36 inches, 44 inches, 56-60 inches, etc., which are called narrow, medium, and wide, respectively. Fabrics higher than 60 inches are Extra-wide fabrics are generally called wide fabrics. The width of ultra-wide fabrics in China today can reach 360 cm. The width is generally marked after the density. For example, if the fabric mentioned in 3 adds the width, it will be expressed as: "45X45/108X58/60"" that is, the width is 60 inches.
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 fabrics usually take the 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.;
Japanese called "first dyed fabric", which 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" and it is a factory that produces dyed fabrics. It is generally called a dyeing and weaving factory, such as denim, and most of the shirt fabrics are yarn-dyed fabrics;
