The role of crimp in the post-processing of chemical staple fiber
This function is as follows:

1. Crimping can make chemical fibers curl to a certain extent, and increase the friction and cohesion between fibers.

2. Curl can increase the curl between fibers, make the fabric soft and plump, and have good wrinkle resistance and warmth retention.

3. Curling helps to improve the durability and service life of textiles.
