Theoretically, pure wool coat is easier to pilling, because wool itself is easy to get together because of friction, do you know wool felt? The oldest one is made of pure wool. Its principle is that it can be made into felt by rubbing it together. You say pure wool cannot pilling. Of course, what I just mentioned is an extreme case. The international community has been using a series of complex processes to organize its pilling. So far, this problem has not been solved perfectly, but there is some relief. Therefore, pilling depends not only on the material itself, but also on the manufacturing process. Another very important point is the composition of the blend. Generally speaking, there is no pure wool coat on the market. If any tag says that 100% pure wool is fake, no matter how expensive it is, it does not mean the problem of raw materials, but depends on the comprehensive conditions such as fiber abrasion resistance, fuzzing and pilling, If it is not pure, other non wool ingredients are particularly critical. Some chemical fibers are easier to balloon. Hey hey, it's not only easy to pillage, but also easy to generate static electricity. Nylon, polyester and acrylic fibers are all pilling, so the fairy should pay more attention to these blended materials.
To sum up, the pilling performance of wool overcoat has nothing to do with the wool content, which depends on the comprehensive situation in many aspects.
