OPERATING SKILLS IN GRINDING PROCESS

Because the grinding effect of fabrics is at the cost of sacrificing the strength of fabrics, there is a problem of optimum balance between the grinding effect and the strength of fabrics. To grasp the balance between the two requires that sandpaper films be produced strictly in accordance with the grinding process parameters and operating rules.

A. Grinding is to cut the fabric yarn with some fibers by sand grains to produce uniform hairiness. If the cut is too deep, the hairiness will be long and the strength loss of the fabric will be great.

B. Thicker sandpaper is cut deep and sparse. The feathers on the cloth surface are long and sparse and easy to drop. The cloth surface is like "radish" strips. The fabric is weightless and the strength loss of the fabric is large.
