Textile Fabric Concept

Knitted fabrics are divided into weft knitted fabrics and warp knitted fabrics according to the weaving method. Weft knitted fabrics are often made of low-elastic polyester yarn or special-shaped polyester yarn, nylon yarn, cotton yarn, wool yarn, etc. Circle weave, etc., woven on various weft knitting machines.

Warp Density

The length direction of the fabric; the yarn in this direction is called the warp; the number of yarns arranged within 1 inch is the warp density (warp density);

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);

Density

It is used to indicate the number of yarns per unit length of a woven fabric, generally the number of yarns within 1 inch or 10 cm. my country's national standard stipulates that the number of yarns within 10 cm is used to indicate the density, but textile enterprises are still used to using The number of yarns in 1 inch 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.

Width

The effective width of the fabric is generally expressed in inches or centimeters. Commonly used 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 is generally called wide cloth, and the width of extra-wide fabrics in my country today can reach 360 cm. The width is generally marked behind the density, such as: If the fabric mentioned in 3 is added with the width, it will be expressed as: "45X45/108X58/60"", which means the width is 60 inches.

Gram Weight

The gram weight of the fabric is generally the number of grams of the square meter of the fabric, and the gram weight is an important technical indicator of knitted fabrics. Woolen wool usually also takes the gram weight as an important technical indicator. The gram weight of denim fabrics is generally expressed in "ounces (OZ)", that is, the number of ounces of fabric weight per square yard, such as 7 ounces, 12 ounces of denim, etc.;

Yarn-dyed

In Japan, it is called "dyed fabric first", which refers to the process of first dyeing yarn or filament, and then using dyed yarn for weaving. This kind of fabric is called "dyed fabric". For dyeing and weaving factories, such as denim, and most shirting fabrics are yarn-dyed
