Problems solved by technology

[0006] However, the main problems of the above-mentioned artificial cowhide bonded with the cow fiber leather base cloth and the polyurethane coating layer are: the first is that the way of laying the net is relatively monotonous, resulting in a large difference in the strength of the made cow fiber leather base cloth in all directions; The second is that normal pressure (3-15MPa) is usually used for spunlace reinforcement, and it is not easy to pierce through spunlace, thereby reducing the mechanical properties of the bovine fiber leather base cloth; the third is the made bovine fiber leather base cloth and PU film The interlayer bonding strength is low; Fourth, drying after spunlace requires a lot of energy, which consumes a lot of energy and has high production costs.

Abstract

The invention relates to the technical field of leather manufacturing, and discloses a preparation process of fully-penetrated cow fiber leather base cloth. The preparation process includes a batching process, a chemical fiber net forming process, a cow leather fiber net forming process, and a process of laminating the chemical fiber net and the cow leather fiber net into a net, wherein the batching process includes taking chemical fibers and cow leather fibers as raw materials for preparing fully-penetrated cow fiber leather base cloth, and batching according to a proportion; the chemical fiber net forming process sequentially includes the working procedures of opening, carding, net laying, pre-wetting and pre-penetrating: in the cow leather fiber net forming process, making cow leather fiber raw materials into a cow leather fiber net by adopting airflow net forming or water flow net forming; and the process for laminating the chemical fiber net and the cow leather fiber net into a net sequentially includes the working procedures of laminating the net, spunlacing, vacuum suction and drying, and the net laying working procedure includes warp cross laying and weft cross laying. The preparation process improves the physical properties of the cow fiber leather base cloth and reduces the production cost.

Description

technical field [0001] The invention relates to the technical field of leather manufacturing, in particular to a preparation process for a fully pierced cow fiber leather base cloth. 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...
