Core spun yarn taking collagenous fibers as main material and as leather layer and processing method of core spun yarn

Abstract

The invention discloses a core spun yarn taking collagenous fibers as a main material and as a leather layer and a processing method of the core spun yarn. The core spun yarn comprises a core yarn, wherein a leather layer formed by collagenous fiber bundles or a collagenous fiber bundle and other textiles covers or cover the core yarn; a collagenous fiber bundle and a branch thereof and an adjacent collagenous fiber bundle and a branch thereof form three-dimensional meshed structures which are mutually staggered, twisted and combined and axially arrayed. The processing method of the core spun yarn taking the collagenous fibers as the main material and as the surface layer comprises the following steps: (1) extracting collagenous fibers; (2) carding and striping the fibers; (3) drawing the fibers; and (4) performing spinning. According to the core spun yarn and the processing method thereof, the problem that the basic tensile strength cannot be achieved by extracting the collagenous fibers from leather and directly spinning the fibers in the prior art is solved, and the shortcoming that fine yarns are very hard to process or cannot be processed and the shortcoming that a product cannot fully exert the characteristic of the collagenous fibers as a large number of other textile fibers must be blended for spinning are overcome.

Description

Technical field [0001] The invention relates to yarns, in particular to a core-spun yarn mainly using collagen fiber bundles as a skin and a processing method thereof. Background technique [0002] Collagen fiber bundles are taken from animal leather. Leather is formed by tanning the remaining dermis after removing the epidermal layer and subcutaneous tissue layer from the skin peeled off from the animal. Collagen fiber is the dermis. The main fiber in the dermis, which constitutes the main body of the dermis, accounts for 95% to 98% of all the fibers in the dermis. The collagen fibers are in bundles. The formation process is as follows: collagen molecules → protofibrils with a diameter of 1.2 to 1.7 nm → diameter Sub-fibrils with 3~5nm→fibrils with a diameter of about 20nm→fine fibers with a diameter of 2~5μm→collagen fiber bundles with a diameter of 20~150μm. [0003] Because collagen fiber has many advantages such as good moisture absorption, warmth retention, softness, flame r...

Problems solved by technology

[0008] The purpose of the present invention is to provide a core-spun yarn with collagen fibers as the main cortex and its processing method, to solve the problem that the prior art extracts collagen fibers from leather and directly spins them to achieve basic tensile strength, and solves the problem of It is extremely difficult or impossible to process high-count yarns, and it solves the disadvantage that it must be mixed with a large amount of other textile fibers for spinning, so that the product cannot fully exert the excellent properties of collagen fibers
