Raw material sorting. This is the primary key to the processing of crushed leather, determining the quality of the product.

Firstly, classify the raw materials according to animal species, and then classify them according to their parts such as head, seat, block, leg, spine, tail, and throat, with a requirement for left and right order and front and rear legs.

The processing technology of mink skin is called "piercing knife". When buying mink skin, you can carefully touch it with your fingers on a large flat surface, and you can find the edges one by one. This is the "piercing knife" process. "Piercing knife" is to cut the "mouth" into "llll", which is to cut a piece of mink skin into small finger wide strips, and then sew them again. The stitching is particularly fine, much thinner than the embroidery stitches. This is to increase the size of the skin, which is reasonable, but not the main purpose. Secondly, to make the clothing have a natural drape and dynamic feeling after processing, otherwise using the entire mink skin to sew will have an unsightly effect, which is easy to produce a large number of wrinkles and folds. It is also reasonable to do so for the effect of not sticking to the clothing. In the stitching, special thread is used for very fine and dense stitching.

Mesh weaving is a fur processing technique that cuts the entire leather or the edges and corners of a certain part of the raw material into uniformly wide fur strips, which are then connected and woven on the net to create exquisite woven fur clothing.
