Common concepts of gray cloth
l Weft direction, weft yarn, weft density – fabric width direction; the yarn spun in this direction is called weft yarn, and its 1-inch inner spun The number of yarns arranged is the weft density (weft density);
l Density – used to represent woven fabrics The number of inner-spun yarns per unit length is generally the number of inner-spun yarns in 1 inch or 10 centimeters. my country’s national standards stipulate that the number of inner-spun yarns in 10 centimeters is used to indicate density, but fabric companies are still accustomed to using 1 inch. The number of inner spinning yarns represents the density. For example, the commonly seen “45X45/108X58” means that the warp and weft yarns are 45 respectively, and the warp and weft densities are 108 and 58.
l Effective width – the effective width of the cloth , generally expressed in inches or centimeters, the 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 width, which are usually It is called wide cloth. The effective width of extra wide cloth in my country today can reach 360 cm. The effective width is generally marked after the density. For example: if the fabric mentioned in 3 is added with the effective width, it is expressed as: “45︸45/108︸58/60 “”That is, the effective width is 60 inches.
l Weight per square meter – fabric Weight per square meter is generally the number of grams of fabric weight per square meter. Weight per square meter is an important technical indicator for knitted fabrics. Woolen woolen fabrics usually also use weight per square meter as an important technical indicator. Denim fabric per square meter The weight in meters is generally expressed in ounces (OZ), which is the number of ounces per square yard of fabric weight, such as 7 ounces, 12 ounces of denim, etc.;
l Yarn-dyed fabric—called “in Japan” “First dyeing fabric” refers to the process of dyeing the yarn or filament first, and then using the colored yarn to weave the fabric. This kind of fabric is called “dyed fabric”, and the factory that produces the dyed fabric is generally called dyeing. Weaving factories, such as denim, and most shirt fabrics are dyed fabrics.
