1. Strengthen the styling effect in finishing: (1) Carry out on the super-feed pin tenter when drying; (2) Try to reduce the warp tension when drying. 2. Relaxation and pre-shrinking: (1) Moisten the fabric to place it in a relaxed state for a certain period of time, and then dry it slowly. (2) Take the forced pre-shrinking method. Expose the fabric to steam under tension-free state, oscillate or shake, and then maintain high-speed cooling under tension-free state to obtain forced retraction.
