Pre-shrinking of the pre-shrinking machine

Nov 04, 2020

Pre-shrinking finishing: 1. Strengthen the shaping effect in finishing. (1) Drying is carried out on the super-feed pin tenter; (2) The warp tension is minimized 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 slowly dry. (2) Take the forced pre-shrinking method. Expose the fabric to steam in a tension-free state, oscillate or shake, and then maintain a high-speed cooling under tension-free state to obtain forced retraction.
