Sanding

It refers to using a sanding roller or metal roller to rub against the fabric surface, and combining different sanding mesh numbers for different fabrics to achieve the expected sanding effect.

The general principle is to use high grit sanding for high count yarns, and low grit sanding for low count yarns. The sanding rollers have both forward and reverse rotation, and odd numbered sanding rollers are generally used.

Scratch hair
