Problems solved by technology

Through this scheme, the content of other fibers doped in the regenerated leather is increased, but because the price of the hot-melt adhesive fiber is close to that of the collagen fiber, and the weight percentage of the viscose fiber in the upper web is only 60%, so the Although the production cost of regenerated leather is lower than that of the former scheme, there is not much room for reduction

Embodiment 1~5

[0036] The invention relates to a collagen fiber regenerated skin with low production cost, which is composed of a lower layer of fiber web and an upper layer of fiber web tightly connected to the surface of the lower layer of fiber web, wherein the material composition and weight percentage of the lower layer of fiber web are: collagen fiber 0~ 39%, viscose fiber 61~100%; the material composition and weight percentage of the upper fiber web are: collagen fiber 85~100%, viscose fiber 0~15%. In Examples 1 to 5, the material composition of the lower fiber web, the material composition of the upper layer fiber web, and the respective weight percentages of the upper and lower layer fiber webs in the total weight of the upper and lower layer fiber webs are shown in Table 1.

[0037] In embodiment 1, the manufacture method of the collagen fiber regenerated skin of this low production cost comprises the following steps successively:

[0038] (1) Defibrilation: Defibril the pig, sheep...

Embodiment 2

[0043] In embodiment 2, the method of this collagen fiber regenerated skin is similar to the method described in embodiment 1, only difference is: since the lower layer fiber web accounts for 90% of the upper and lower layer fiber web gross weight in the present embodiment, therefore In step (3), it is enough to use an air-laid machine to lay the fibers forming the upper fiber web on the upper surface of the lower fiber web to form an upper fiber web, thereby achieving high cloth speed and high production efficiency; wherein, carding The web laying machine is responsible for 90% of the final fiber web weight, and the air-laid machine is responsible for 10% of the final fiber web weight.

Embodiment 3

[0044] In embodiment 3, the method of this collagen fiber regenerated skin is similar to the method described in embodiment 1, and difference is: at first, because upper and lower web all only contain a kind of fiber respectively, so in step (2), The fibers that make up the upper and lower fiber webs only need to be opened by one opener, and then they can enter the web laying process. There is no need for fiber mixing and fiber opening before opening. Secondly, because the lower layer of fiber web accounts for 80% of the total weight of the upper and lower layer of fiber webs in the present embodiment, so in step (3), it is enough to form the fibers of the upper layer of fiber web on the lower layer of fiber web with two air-laid machines. The upper surface is laid into the upper fiber web, so as to achieve high cloth speed and production efficiency; among them, the carding machine is responsible for 80% of the weight of the final fiber web, and the two air-laid machines are re...

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. [0003] For the regenerated lea...
