The purpose and mechanism of shrinking

Jan 31, 2021

  The purpose of pre-shrinking finishing: make the fabric obtain a stable shape. The use of a pre-shrinking machine for pre-shrinking can reduce the warp shrinkage of the fabric. Improve the dimensional stability of the fabric during the wearing process and reduce the shrinkage rate. Pre-shrinking mechanism: After the wetted fabric is passed through the tentering device, it is placed on the outer surface of the felt in a loose state, and the felt is covered on the small diameter cloth feeding roller, and the outer surface is stretched; Covering the large drying cylinder with reverse curvature, the stretched felt surface shrinks, and the fabric close to it is also forcibly shrinked to play a pre-shrinking effect.
