Problems solved by technology

[0006] But the main problem that the above-mentioned imitation cowhide that exists with bovine leather base cloth and polyurethane coating layer bonding is following drawback: the one, tensile strength is not high, and the cohesive strength between the layers is low, and it is easy to peel off after using for a long time ; Second, the softness is not good and the hand feel is poor
This affects the final performance and quality of the simulated cow leather products

Abstract

The invention relates to the technical field of leather manufacturing, and discloses a preparation process of an ultra-soft cow fiber leather. The preparation process includes the following process steps: step 10. preparation of semi-finished cow fiber leather; step 20. preparation of an oil return liquid: mixing deionized water, softening oil for leather softening, lanolin, a penetrant and mildew-proof oil to prepare the oil return liquid; step 30. oil return treatment; step 40. regular infiltration; step 50. softening treatment: adopting a softening device, placing the semi-finished cow fiber leather penetrated at a fixed time into a rotary drum body of the softening device, mixing a plurality of beating balls into the rotary drum body, and rotating the rotary drum body to beat the semi-finished cow fiber leather; and step 60: trimming. According to the preparation process, the bonding strength between the base cloth and a PU film in the cow fiber leather product is improved, and the softness of the cow fiber leather product is improved.

Description

technical field [0001] The invention relates to the technical field of leather manufacturing, in particular to a preparation process for extra-soft cow fiber leather. Background technique [0002] Leather is an indispensable category of production and daily necessities in human life, and is widely used in many fields such as clothing, home furnishing, automobiles, and public services. A large number of scraps of natural leather are produced in the production process of leather products, and the amount of scraps of natural leather is large. If it can be used twice, especially processed into cow fiber leather, it will produce Considerable wealth, and at the same time have positive significance for green energy conservation and environmental protection. [0003] The traditional regenerated leather is to crush all kinds of leather and animal skin scraps into powder, and then bond and press the powder into a whole piece of regenerated leather through adhesives or hot-melt fibers...
