Embodiment 1

[0043] The invention relates to a collagen fiber regenerated leather, which is composed of an upper layer fiber web and a lower layer fiber web tightly connected to the lower surface of the upper layer fiber web, wherein, the material composition and weight percentage of the upper layer fiber web are: collagen fiber 40%, viscose 60% glue fiber; the material composition and weight percentage of the lower fiber web are: 92% collagen fiber, 8% hot-melt adhesive fiber; the length of the collagen fiber is 1-3cm. The thickness of the regenerated leather is 0.5-3 mm, the transverse and longitudinal tear strengths are both above 23N, and the transverse and longitudinal tensile strengths are both above 68N. Among them, taking the performance of regenerated leather with a thickness of 1 mm as an example, the results are shown in Table 1.

[0044] The present invention also relates to a method for manufacturing the above-mentioned collagen fiber regenerated leather, which comprises the f...

Embodiment 2

[0052] The invention relates to a collagen fiber regenerated leather, which is composed of an upper layer fiber web and a lower layer fiber web tightly connected to the lower surface of the upper layer fiber web, wherein, the material composition and weight percentage of the upper layer fiber web are: collagen fiber 97%, viscose Glue fiber 3%; the material composition and weight percentage of the lower fiber web are: 98% collagen fiber, 2% hot-melt adhesive fiber; the length of the collagen fiber is more than 1cm, preferably 1-3cm in length. The thickness of the regenerated leather is 0.5-3 mm, the transverse and longitudinal tear strengths are both above 23N, and the transverse and longitudinal tensile strengths are both above 68N. Among them, taking the performance of regenerated leather with a thickness of 1 mm as an example, the results are shown in Table 1.

Abstract

The invention relates to collagen fiber regenerated leather which comprises an upper layer fibre web and a lower layer fibre web closely connected with the lower surface of the upper layer fibre web, wherein the upper layer fibre web comprises the following materials by weight: 40 to 97 percent of collagen fiber, and 3 to 60 percent of viscose fibre; the lower layer fibre web comprises the following materials by weight: 92 to 100 percent of collagen fiber, and 0 to 8 percent of hot melting bonding fibre; and the length of collagen fiber is more than 1 cm. Through the adoption of the structure that one side of the fibre web is mixed with low cost viscose fibre; and the other side of the fibre web contains at least 92 percent of collagen fiber in percentage by weight in the regenerated leather, the collagen fiber regenerated leather has the advantages that the production cost of the regenerated leather is reduced; meanwhile the regenerated leather has a hand feeling similar to dermis after being compounded with other cloth layer or leather layer; and regenerated leather can be used for making advanced handbags , board-type sofa material and the like. The invention further relates to a technology method used for manufacturing the collagen fiber regenerated leather.

Description

technical field [0001] The invention relates to a nonwoven material and a manufacturing method thereof, in particular to a collagen fiber regenerated leather 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. [0003] 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. [0004] For the regenerated leather obtained ...
