Spinning classification

Yarn: Yarn is a continuous fiber bundle made of short fibers assembled by twisting.

 Variety: 

 1. According to the thickness of the yarn: coarse special yarn, medium special yarn, fine special yarn

 2. According to textile technology: combed yarn, carded yarn

 3. According to dyeing processing: primary color yarn, dyed yarn, color spinning, bleached yarn, mercerized yarn

 4. By spinning method: ring spinning, open-end spinning, electrostatic spinning, vortex spinning, siro spinning

 5. By fiber length: cotton yarn, medium length yarn, wool yarn, filament yarn

Thread: Thread is made of two or more single yarns combined and twisted, or strands.

 Variety: 

 1. According to the shape and structure of the yarn: single yarn, stranded yarn, multi-stranded yarn, fancy yarn, textured yarn

 2. According to the types of fibers that make up the yarn: pure spun yarn, blended yarn

 3. By application: yarn for weaving, yarn for knitting, yarn for raising, yarn for sewing, special industrial yarn

Performance:

 Linear density---refers to the thickness of the yarn, according to the national standard, it is called tex, abbreviated as tex, the symbol is tex, 1tex=1g/km.

 Twist --- the number of twists per unit length of yarn. The twist of the yarn is directional and can be divided into Z twist and S twist. Generally, the single yarn is Z twist, the plied yarn is S twist, and the plied yarn is generally represented by Z/S.

 Moisture regain --- Since the hygroscopicity of fibers and yarns changes with the surrounding environment, the moisture regain of various textile materials is uniformly specified in commercial trade for the convenience of pricing.
