Abstract

The invention provides a preparation method for a chenille oar leather product. The preparation method comprises the following steps that (1) chenille fur after retanning and dyeing is neatened for the first time; (2) the fur after processing in the first step is subjected to staking and leather buffing and then is neatened for the second time; (3) a top side of the fur after processing in the second step is subjected to bottom oar spraying, color paste spraying and top oar spraying in sequence; (4) after the fur after processing in the third step is milled, wax change effect leather is obtained. A wax color change effect glaze can be obtained from a chenille flesh side. The product has good color fastness to light, dry and wet rubbing color fastness and PVC transfer resistance.

Description

technical field [0001] The invention relates to a method for preparing sheep shearling pulp leather products, and belongs to the technical field of fur processing and finishing. Background technique [0002] In the process of tanning, the surface quality is an important index to measure the quality of leather, and the surface finishing of leather is a very important process that affects the quality of leather surface. Existing pulp leather products are to utilize roller coating to roll the pattern of flower roller onto the leather. Sheep shearling has a wool surface and a board surface, and the processing of pulp leather can only be carried out on the board surface of sheep shearling. During the preparation process, it is necessary to use a roller coater to repeat the roller pattern, which is inefficient and cannot be obtained. Brightly colored starch leather products. Contents of the invention [0003] The main purpose of the present invention is to provide a kind of pr...
