Dedicated to textile novices (four) - textile common concepts

1. warp, warp, warp density - length direction of the fabric; the spun yarn is referred to as warp yarn; the number of rows of the 1 inch inner spun yarn is dense (warp density);

2, weft, weft, weft density - fabric width direction; the yarn is called weft yarn, the number of rows of the 1 inch inner spinning yarn is weft density (weft density);

3. Density--It is used to indicate the number of spinning yarns in the unit length of the shuttle cloth. It is usually the number of spinning yarns of 1 inch or 10 cm. The national standard specifies the number of spinning yarns of 10 cm. Density, but textile companies are still accustomed to using the number of 1 inch inner spinning yarn to indicate density. As commonly seen, "45X45/108X58" means that the warp weft is separated by 45, and the warp and weft density is 108, 58.

4, the effective width - the width of the fabric, the common habit is expressed in inches or centimeters, the common are 36 inches, 44 inches, 56-60 inches, etc., the separation is called narrow, medium and wide, above 60 The inch of fabric is extra wide, and the usual width is usually wide. The effective width of today's extra-wide fabric can reach 360 cm. The effective width of the general mark is after the density, such as the cloth mentioned in 3, if the effective width is added, it means: "45X45/108X58/60"", the effective width is 60 inches.

5, the weight per square meter - the weight per square meter of fabric is generally the number of grams of fabric per square meter, the weight per square meter is an important technical index of knitted fabrics, woollen wool usually also takes the weight per square meter Important technical indicators. The weight per square meter of denim fabric is usually expressed in "ounces (OZ)", that is, the number of ounces per square yard of fabric, such as 7 ounces, 12 ounces of denim, etc.;

6, yarn-dyed - Japan called "first dyed fabric", refers to the process of first spinning the yarn or filament, and then using the color yarn for weaving, this fabric is called "dyed fabric", The factories that produce yarn-dyed fabrics are commonly referred to as dyeing and weaving factories, such as denim, and most of the shirt fabrics are dyed fabrics;
