Pre-shrinking of the pre-shrinking and finishing machine

Jan 29, 2021

  Pre-shrinking finishing: 

1. Strengthen the shaping effect in finishing. 

(1) When drying, it is carried out on the super-feed pin tenter; 

(2) When drying and finishing, try to reduce the warp tension. 

2. Relaxation and pre-shrinking: 

(1) Humidify 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 in a tension-free state, oscillate or shake, and then maintain a high-speed cooling under tension-free condition to obtain forced retraction.
