Pilling phenomenon in addition to by wearing improper or with hard objects caused by friction, some of the more loose fibers in the clothing after wearing a few times will fall off or tangled together, and the formation of pilling, which is completely normal. Even the best cashmere sweaters will have a slight pilling effect in the moderate range when they are first worn.
1. Due to the particularity of the fiber itself, pilling of cashmere products is caused by the following factors:
(1) Length of fiber: The pilling degree of fabrics woven with longer fibers is lighter than that of fabrics woven with shorter fibers; Due to the small number of fiber ends per unit length, there are fewer fiber ends on the surface of yarn and fabric. The length of cashmere fiber is 35 ~ 45 mm, while the length of wool fiber is 70 ~ 140 mm.
(2) Fineness of fibers: coarse fibers are less likely to pilling than fine fibers. The number of fiber roots per unit area of the yarn made of coarse fiber is less, and the fiber ends on the surface of the yarn and the fabric are less. In addition, the thicker and stiffer the fiber, the less likely it is to pare up on the surface of the fabric. The fineness of cashmere is significantly less than that of wool.
(3) Crimp degree of fiber: more crimp of fiber, greater cohesion between fibers, increased friction, fiber is not easy to free to the fabric surface, it is not easy to pilling. Cashmere curls less than wool.
