The chemical fiber felt is often subjected to various external forces such as stretching, crimping, and torsion during the processing process, which causes the fiber to change its original shape. Because wool has good elasticity, it tries to return to its original shape. Therefore, various stresses are generated in the fiber. This internal stress needs to be gradually attenuated and eliminated over a long period of time. It is often used in the processing of wool products.
