Collagenous fiber regenerated leather low in production cost and manufacturing method thereof

Abstract

The invention relates to a collagenous fiber regenerated leather low in production cost and a manufacturing method thereof. The regenerated leather is composed of double-layer fiber nets, wherein the double-layer fiber nets on one side contain low-cost viscose fibers which achieve 100% in weight, and the double-layer fiber nets on the other side are collagenous fibers. During recombination, one side, containing a large number of the viscose fibers, of the regenerated leather and other cloth layers or leather layers are recombined, and therefore adulteration of the viscose fibers does not affect hand feeling of the regenerated leather. Meanwhile, as the regenerated leather contains a large number of the viscose fibers, the production cost of the regenerated leather is greatly reduced. The double-layer fiber nets on one side can contain the low-cost viscose fibers, besides, the viscose fibers achieving 15% to the maximum in weight can be adulterated in the double-layer fiber nets on the other side, and the cost of the regenerated leather is further reduced. According to the method of the collagenous fiber regenerated leather, effective winding between the upper fiber nets and the lower fiber nets is formed in a puncture fixing mode, and the strength of the regenerated leather is guaranteed. In addition, the species and the number of net laying devices of the collagenous fiber regenerated leather can be regulated according to the ratio of the upper fiber nets and the lower fiber nets so that high cloth passing speed and high production efficiency can be achieved.

Description

technical field

[0001] The invention relates to a non-woven material and a manufacturing method thereof, in particular to a collagen fiber regenerated skin with low production cost and a manufacturing method thereof. Background technique

[0002] The leftovers of natural leather are very large. If they can be reused, especially processed into regenerated leather, considerable wealth will be generated, and at the same time, it will have positive significance for green energy conservation and environmental protection. At present, the methods of utilizing the leftovers of natural corium to process regenerated leather include: fragment bonding method, fiber bonding method and fiber stabbing method. Among them, the regenerated leather obtained by the fiber bonding method has poor hand feeling, but high strength; the regenerated leather obtained by the fiber stabbing method has a slightly lower strength, but the hand feel is close to real leather.
