What are the reasons for the pilling of cashmere blankets?
Pilling is generally caused by friction with hard objects. Some loose fibers will fall off or become tangled together to form pillings after a few uses, which is completely normal. Even the best quality cashmere blankets will have slight pilling when they are first used.
Due to the particularity of the fiber itself, the reasons for the pilling of the cashmere blanket are as follows:
1. Fiber length: The pilling degree of the fabric woven with longer fibers is lighter than the fabric woven with shorter fibers. Due to the small number of fiber ends per unit length, there are fewer fiber ends exposed on the surface of the yarn and fabric. The length of cashmere fiber is 35 to 45 mm, and the length of wool fiber is 70 to 140 mm.
2. The fineness of the fiber: the thicker fiber is less prone to pilling than the thinner fiber. Yarn spun from crude fiber has a small number of fibers per unit area. Fewer fiber ends are exposed on the surface of the yarn and fabric. In addition, the thicker the fiber, the more rigid it is, and the fiber erected on the surface of the fabric is not easy to entangle into a ball. The fineness of cashmere is significantly smaller than that of wool.
3. The degree of crimp of the fiber: the fiber has a lot of crimp, and the cohesion between the fibers is large. The friction increases, and the fiber is not easy to dissociate to the surface of the fabric. It is not easy to pilling. Cashmere has less curl than wool.
