Warp density

——Fabric length direction; the direction of the yarn is called warp; the number of arranged yarns within 1 inch is warp density (warp density);

Weft density

——Fabric width direction: this direction of yarn is called weft, the number of arranged yarns within 1 inch is weft density (weft density);

density

——It is used to represent the number of yarns in a unit length of woven fabric, generally the number of yarns within 1 inch 10 cm. According to Chinese national standard, the number of yarns within 10 cm is used to represent density, but textile enterprises are still used to use the number of yarns within 1 inch to represent density. For example, "45x45 / 108x58" means that there are 45 warp weft yarns respectively, with the warp weft densities of 108 58.

Width of cloth

——The effective width of fabrics is usually expressed in inches centimeters. The common ones are 36 inches, 44 inches, 56-60 inches so on. They are called narrow width, medium width wide width respectively. Fabrics higher than 60 inches are called extra wide, which is usually called wide width. Today, the width of extra wide fabrics in China can reach 360 centimeters. The width is generally marked after the density, for example, if the fabric mentioned in: 3 is added with the width, it means: "45x45 / 108x58 / 60", that is, the width is 60 inches.

Gram weight

——The gram weight of fabric is generally the gram number of square meter of fabric weight, which is an important technical index of knitted fabric, while the gram weight of woolen cloth is also generally regarded as an important technical index. The gram weight of denim fabric is generally expressed in "Oz", that is, the ounce of fabric weight per square yard, such as 7 oz, 12 oz denim, etc;

Yarn dyed weaving

——Japan is called "first dyed fabric", which refers to the process of dyeing the yarn filament first then weaving with colored yarn. This kind of fabric is called "colored fabric". The factories that produce colored fabrics are generally called dyeing weaving factories, such as denim, most of the shirt fabrics are colored fabrics
