Problems solved by technology

But this method needs to separate the ingredients and lay the net, which is troublesome in technology. At the same time, in this method, only the hot-melt adhesive fibers are used to bond the collagen fibers, and there is no effective entanglement between the hot-melt adhesive fibers and the collagen fibers. Adhesive fibers only act like hot-melt powder, making it difficult to fully improve the mechanical strength of regenerated leather

Embodiment 1

[0039] The invention relates to a collagen fiber regenerated skin, the material composition and weight percentage of the regenerated skin are as follows: 92% of collagen fiber and 8% of hot-melt adhesive fiber. Wherein, the length of the collagen fibers is 1-3 cm. The thickness of the regenerated leather is 0.5-3 mm, the tear strength in both the transverse direction and the longitudinal direction is above 23N, and the tensile strength in the transverse direction and the longitudinal direction 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.

[0040] The present invention also relates to a method for manufacturing the above-mentioned collagen fiber regenerated skin, which comprises the following steps in turn:

Abstract

The invention relates to a collagen fiber regenerated bark which is characterized in that the fibre web of the collagen fiber regenerated bark comprises the following materials by weight: 85 to 99 percent of collagen fiber, and 1 to 15 percent of hot melting bonding fibre; both the transversal and the longitudinal tearing strength of the regenerated bark are more than 23 N; both the transversal and the longitudinal tensile strength of the regenerated bark are more than 68 N; the hand feeling is close to dermis; and the collagen fiber regenerated bark can be used for making advanced handbags and board-type sofa material. The invention further relates to a method for manufacturing the regenerated bark, which comprises the following steps in sequence: dissolving fiber, opening, mix-opening, lapping, stabbing, cutting edge, rolling, packaging and the like. Through the adoption of the stabbing process in the method, single hot melting bonding fibre is enabled to form more winding structures with collagen fiber before being heated to bond collagen fiber; and with the help of heat treatment, the collagen fiber regenerated bark has the advantages that the winding structure in the fibre web is fixed; and the web structure compactness in the fibre web is improved, thereby remarkably improving the strength of the regenerated bark.

Description

technical field [0001] The invention relates to a nonwoven material and a manufacturing method thereof, in particular to a collagen fiber regenerated skin 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. [0003] Among them, the fragment bonding method refers to processing the corium into small fragments of corium and then bonding them into leather; the regenerated leather obtained by this method has a hand feel and strength far inferior to natural corium. The fiber bonding method and the fiber stabbing metho...
