The filament yarn is a bundle of filaments (such as natural silk, chemical fiber or rayon); mainly composed of polyester filament, viscose filament, nylon filament and the like.
Fancy yarns are mainly characterized by changes in the appearance or color of the yarn. There are mainly wrapped, core, bamboo, belly, color, wave, braid, towel, circle, knot, feather, toothbrush, enamel, belt, segment dye, chenille and so on.
Yarns are classified according to raw materials
First, pure spinning yarn:
Pure-spun yarns are composed of the same fiber, such as pure cotton yarn, wool yarn, viscose yarn, acrylic yarn, polyester yarn, nylon yarn, and the like.
Second, blended (mixed fiber) yarn:
Blended or cross-twisted yarns are yarns consisting of two or more fibers, such as polyester/cotton blended yarns, wool/polyester blended yarns, wool/nitrile blended yarns, polyester/viscose/nitrile blended yarns. , silk / cotton yarn, crepe and so on. A short fiber yarn of a mixture of two or more kinds of short fibers is called a blended yarn; and a yarn of a combination of two or more kinds of filament yarns (such as twisted yarn) is called a mixed yarn.
1. Yarn twist - the number of twists per unit length. There are Z捻 and S捻 points;
2, carding (carding) - the yarn that is only combed and woven at one end by the carding machine during the spinning process;
3, combing - the use of combing machine in the spinning process to comb the ends of the fiber yarn, less impurities, the fiber is more straight;
4. Blending - a yarn formed by mixing two or two fibers of different nature;
5, yarn count - used to indicate the fineness of the yarn, mainly in the British count, metric count, special number, denier;
6, single yarn - the product directly on the spinning machine will be scattered once it is retracted, referred to as yarn;
7, strands - two or more yarns and twisted together, referred to as the line;
8. Sewing thread - a general term for line products used for sewing sewing products such as garments;
9. New type of spinning - Compared with the traditional spinning method of traditional ring spinning, one end of the spinning process is a free end, such as air spinning, friction spinning, etc., the yarn has no twist, but is entangled.
