Why do we need to pre-shrink cotton fabrics?Cellulose fiber fabrics absorb moisture and breathe, have good performance, but have a large shrinkage rate, often causing inconvenience to consumers. When the fabric is pre-shrinked, the warp direction of the fabric can be prematurely contracted, thereby reducing the shrinkage rate of the finished fabric to meet the quality requirements of garment processing.
The international market has requirements for the warp and weft shrinkage of high-end products, and the commonly used blanket pre-shrinking machine has no shrinkage effect on the weft direction of the fabric. In order to ensure that the latitudinal shrinkage index meets the requirements, the fabric must be finished in the singeing and sizing process before the fabric enters the rubber blanket pre-shrinking machine. The effect of the web shrinkage, thus ensuring that the pre-shrinked finished product meets the double shrinkage requirements
