Problems solved by technology

In the leather field, solvent-based materials are basically used for processing release paper, but when solvent-based materials are used for processing, the configured solvent-based materials will be sprayed on the release paper. The spraying process will cause harmful gases to volatilize, causing Environmental pollution, and the use of solvent-based materials will also bring about the problem of excessive DMF and VOC, which is not friendly to the environment

Abstract

The invention discloses a finishing process of a linerless bag leather, which comprises the steps of finishing the leather embryo, laminating the front texture of the release paper, laminating the back texture of the release paper, treating the handle, finishing the finished product and the like. The entire process of the present invention combines the new release paper process to realize environmental protection coating, which is very friendly to the environment and achieves zero emission of harmful gases; realizes double-sided bag products, breaking the pattern of conventional lined bags; breakthrough The combination of reverse roller coating and forward roller coating realizes the clean production of both sides of bag leather without cross-contamination.

Description

technical field [0001] The invention relates to the technical field of leather processing, in particular to the finishing process of bag leather without lining. Background technique [0002] Bag leather is a category of leather classified according to its use. It can be used for making bags, handbags, handbags, backpacks, backpacks, briefcases, etc. In the market, most of the bags are lined, which makes the bag leather only need to have lines on the front, and does not require too much on the back of the bag leather. However, some existing high-end bags and hand-made bags do not have a lining, which requires both the front and back of the bag leather, and the front and back of the bag leather must have corresponding textures. In the prior art, when the double-sided bag leather is processed, one side of the bag leather is often polluted during processing, which greatly reduces the production efficiency of the double-sided bag leather and also increases the production cost. ...
