Abstract

The invention discloses an air-layer suede fluff sanding technology. The air-layer suede fabric sanding technology comprises the following steps: (1) unwinding; (2) refining; (3) carrying out fiber opening; (4) pre-setting; (5) sanding; (6) dyeing; (7) setting a finished product; (8) brushing fluff; (9) winding. The technology disclosed by the invention has a good gigging effect and the neatness,length and density of the fluff can be effectively controlled and a technological flow is simplified.

Description

technical field [0001] The invention relates to the technical field of textile fabrics, in particular to an air layer suede sanding process. Background technique [0002] Suede is a fabric made of animal suede. Many properties of suede fabric are not inferior to natural suede, and many properties are even better than natural suede, such as the fabric has soft wool, waxy, good drapability, and light and thin texture. The existing dyeing, finishing and sanding process of suede is relatively complicated, the napping effect is not good enough, and the uniformity and hand feel of the suede need to be improved. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art, and provide an air layer suede suede sanding process, which has good napping effect, can effectively control the uniformity, length and density of the nap, and simplifies the process flow. [0004] In order to achieve the above object...
