Do you know about pre-shrinking and calendering?

Pre-shrinking finishing:

In the process of printing and dyeing, the fabric is stretched by mechanical tension and has internal stress. When the fabric is wet, the internal stress relaxes, which will cause a shrinkage effect. Therefore, in the actual production, the fabric must be mechanically pre-shrinked to reduce the cotton fabric. The shrinkage rate keeps the finished product dimensionally stable, keeps the fabric neat and improves the added value of the product.

Calendering treatment:

Also called calendering. A process of fabric finishing. A finishing process that uses the physical plasticity of fibers under high pressure or high temperature to flatten or emboss the surface of the fabric to increase the luster of the fabric. Similar to ironing, the method of flattening and ironing the surface makes the fabric have a special luster, enhances the brightness of the fabric, and makes the fabric drape and smooth.
