As a textile term, hairiness is an important quality index that affects the appearance and style of yarns. The state of yarn hairiness directly affects the weaving efficiency, cloth style and dyeing effect. Yarn hairiness refers to the fiber end or loop that protrudes from the yarn body. Hairy feathers are intricate and intricate. The hairy feathers protruding from the yarn have ends, loops, and fibers attached to the surface. They have directionality and strong mobility, as shown in Figure 2-17. Hairy feathers cause the appearance of yarns and reduce the appearance of yarns. Excess yarn hairiness will affect the normal sizing, and during the weaving process, the opening will be unclear and the breakage will increase. The number and distribution of yarn hairiness have a major influence on the quality of the fabric and the quality of the dyeing and printing of the fabric, as well as the problem of pilling and pilling during the use of the fabric. Therefore, the yarn hairiness index has become the current important quality assessment index. China and Japan, the United Kingdom, Germany, the United States and other countries use the gross judging index to characterize the number of hairinesses. The definition of the hairiness index is: over a certain projection length on one side of the unilateral yarn plane view of the unit yarn length ( The total number of hair feathers in the vertical distance, in units of root / 10m (the size of the indicator is affected by factors such as test length and projection length). The compact spinning in the new type of spinning yarn can well control the hairiness of the yarn. Compared with the ring yarn, the hairiness of the yarn surface is reduced by more than 8mm by 80%.
