[0006] However, the above-mentioned imitation cow leather bonded with cow fiber leather base cloth and polyurethane coating layer generally has poor physical properties (such as low mechanical strength), poor hand feeling, and lacks genuine leather feeling, thus affecting the simulation cow leather products. the quality of
In addition, during the preparation process of imitation cow leather, its energy consumption is relatively large, which leads to the increase of manufacturing cost

Embodiment 1
[0082] Such as Figure 1 to 6 Shown is an example of the preparation process of a spunlace-entangled recycled cow leather of the present invention, including a batching process, a cowhide fiber web forming process, and a mixed fiber web forming process that is sequentially set according to the preparation process, and a lamination Netting process, base fabric production process, cow leather production process;
[0083] Wherein, in the batching process, mixed fiber and cowhide fiber are used as raw materials and proportioned by weight; the mixed fiber is a mixed fiber using at least two fibers among regenerated fiber, chemical fiber, and cowhide fiber;
[0084] Wherein, the cowhide fiber web forming process includes a process of forming the cowhide fiber into a cowhide fiber web by using a dry or wet method;
[0085] Wherein, the mixed fiber web forming process includes the carding process of the blended fiber, the web laying process, and the spunlace preforming process in sequence; ...
Embodiment 2
[0132] According to the preparation process of Example 1, the production of spunlace-wrapped recycled cow leather is carried out, and in the batching process, the weight ratio of the mixed fiber and the cowhide fiber is set to 1:4, and the cowhide fiber in the mixed fiber is set at the same time. The content is 45%, and the total content of cowhide fiber is (1×45%+4)÷(1+4)×100%=89% cow leather; the cow leather is used for the production of sofas and bags.
Embodiment 3
[0134] According to the preparation process of Example 1, the production of spunlace-wrapped recycled cow leather is carried out, and in the batching process, the weight ratio of the mixed fiber and the cowhide fiber is set to 1:3, and the cowhide fiber in the mixed fiber is set at the same time. The content is 40%, and the total content of cowhide fiber is (1×40%+3)÷(1+3)×100%=85% cow leather; the cow leather is used for the production of sofas and bags.

Abstract
The invention relates to the technical field of leather manufacturing and discloses a preparation process of spunlace winding type cyclic cow leather. The preparation process comprises a matching process, a cow leather fiber web forming process as well as a mixed fiber web forming process, a stacked web forming process, a base cloth production process and a finished cow leather product productionprocess which are set sequentially according to the preparation process; the base cloth production process comprises a polishing process, a single-sided impregnation process and an ironing process which are set sequentially to produce a stacked web into base cloth; the single-sided impregnation process includes performing single side coating treatment with a water-based PU material or an oil-basedPU material as a coating on a single side of the base cloth by adopting an inverted feeding device so as to form a single-sided permeation impregnation layer of the base cloth. The physical performance and hand feel of the cow leather product are improved, the sense of genuine leather is enhanced, and meanwhile, energy consumption in the production process is reduced.
Description
Technical field [0001] The invention relates to the technical field of leather manufacturing, in particular to a preparation process of spunlace winding type circulating cow leather. Background technique [0002] Leather is an indispensable large-scale production and daily necessities in human life. It is widely used in many fields such as clothing, footwear, home furnishing, automobiles, and public services. A large amount of scraps of natural leather are produced in the production process of leather products. The amount of scraps of natural leather is very large. If it can be recycled, especially if it is processed into cattle fiber leather, it will produce quite Great wealth, at the same time, has a positive meaning for green energy conservation and environmental protection. [0003] Traditional recycled leather is to pulverize all kinds of leather and animal skin scraps into powder, and then bond and press the powder into a whole piece of recycled leather through adhesive or h...
