Problems solved by technology

Therefore, when the existing sheep shearing leather is finished, because the surface of the sheep shearing is uneven, the coating will penetrate unevenly into the skin, which will cause problems such as peeling and contamination in the later production process, which will affect the quality of the fur. Hand and Color Uniformity
Moreover, the traditional fur leather board surface finishing is to use solvent-based waterproof materials or fluorine-containing acrylic polyurethane polymers. Solvent-based waterproof materials have a strong smell, pollute the air, and have certain harm to the human body. Seriously harmful to humans and animals

Abstract

The invention belongs to the technical field of fur processing, and particularly relates to a fluoride-free environment-friendly fur coating process which is characterized in that a plate surface of fur is treated through a fluoride-free waterproof material, so that a compact fluoride-free waterproof film layer is formed on the plate surface, and the phenomena of over-hardness, peeling and the like of a fur body caused by excessive permeation of the coating material into a leather plate are prevented. The fur subjected to bottom sealing is coated with a cation layer through a cation material, namely the plate face of the fur is further sealed after the fluoride-free waterproof layer is arranged, non-ionic color paste is prevented from permeating into the fur plate too much, and the coated fur is good in hand feeling, oily, natural, skin-friendly and wear-resistant. A fluoride-free waterproof material is used for bottom sealing, and then a cationic material and a nonionic color paste material are sprayed, so that the fur board surface has a good coloring effect, and the fur board surface is natural, skin-friendly and wear-resistant after being coated.

Description

technical field [0001] The invention belongs to the technical field of fur processing, in particular to a fluorine-free and environment-friendly fur finishing process. Background technique [0002] With the continuous improvement of people's living standards, fur clothing is no longer just for the needs of keeping out the cold, but requires its high quality and attractive appearance. Therefore, when the existing sheep shearing leather is finished, because the surface of the sheep shearing is uneven, the coating will penetrate unevenly into the skin, which will cause problems such as peeling and contamination in the later production process, which will affect the quality of the fur. Hand and color uniformity. Moreover, the traditional fur leather board surface finishing is to use solvent-based waterproof materials or fluorine-containing acrylic polyurethane polymers. Solvent-based waterproof materials have a strong smell, pollute the air, and have certain harm to the human b...
