Yes, in fact, uh, cotton fabrics are not 100 percent unpilling either, because cotton fabrics are also divided into several grades. The best pure cotton is made from the longest fiber extracted from cotton. After the FUZZING treatment, a good pure cotton fabric will have a layer of soft and comfortable fluff on the surface. Any fabric with hair on the surface, after friction, the surface of the hair fibers will be tangled together, forming a pilling phenomenon. But why is the fabric of pure cotton not pilling easily? And Chemical Fiber always appears so obvious pilling phenomenon? That is because the chemical fiber than pure cotton fiber strength, high toughness, so up after the ball is not easy to fall off, long hair ball has been stubbornly staying in the clothes, it seems to be particularly obvious. And the wool ball on pure cotton fabric will be in the process of washing and friction, gradually fall off, so that people form a "cotton won't pilling" understanding.
