Why does wool carpet lose hair?

     During the cutting process, bits and pieces of wool fiber will be scattered in the carpet. Although fully treated by the vacuum cleaner, there are still some bits of hair, in the future use process, under the action of external friction, exposed to the carpet.

      Because wool is a natural fiber, its length has certain limitations, general carpet yarn wool. The length is between 2-5in. (5-13cm) (the length of national wool is 4-12cm, the length of new wool is 7-13cm), which is made by woolen spinning process. Because the carpet surface after scissors cut yarn, flat blanket knife cut flat blanket surface, so that there is some fiber length of the carpet surface is less than the carpet face pile height, resulting in carpet hair.

      After the finished carpet is made, the twist on the yarn surface decreases, the friction between the wool fibers in the yarn decreases, and the length of some fibers is less than the height of the carpet pile (fiber length is less than 10 mm). The strength of these wool fibers fixed in the carpet is not large. Although some scattered wool fibers are reduced after vacuuming treatment, there will still be some wool fibers with low fiber length after cutting in the process of use, which will be taken out of the yarn by tension and friction force and scattered on the carpet surface to form floating hair.
