Core-spun yarn with collagenous fiber bundles as sheath layer and processing method thereof

Abstract

The invention disclosesa core-spun yarn with collagenous fiber bundles as a sheath layer and a processing method thereof, wherein the core-spun yarn comprises a core yarn. The collagenous fiber bundles and residual other textile fibers wrap the core yarn. The collagenous fiber bundles, branches thereof, adjacent collagenous fiber bundles and the branches thereof are intertwined. The processing method of the core-spun yarn with the collagenous fiber bundles as the sheath layer comprises the following steps of (1), extracting the collagenous fiber bundles; (2), performing carding and strip forming; (3), combining the strips; and (4), performing spinning. The core-spun yarn and the processing method settle defects of incapability of reaching basic tensile resistance in direct spinning of the collagenous fiber which is extracted from leather, high difficulty in processing high-count yarn or incapability of processing the high-count yarn. Furthermore a defect of incapability of sufficiently exerting characteristics of the collagenous fiber in the core-spun yarn caused blending a large amount of textile fiber in spinning.

Description

technical field [0001] The invention relates to a yarn, especially a core-spun yarn with collagen fiber bundles as the skin and a processing method thereof. Background technique [0002] Collagen fiber bundles are taken from animal leather, which is formed by tanning after removing the epidermis and subcutaneous tissue layers and performing a series of physical, mechanical and chemical treatments on the remaining dermis. Collagen fibers are dermis The main fibers in the dermis constitute the main body of the dermis, accounting for 95% to 98% of all fibers in the dermis. The collagen fibers are in the form of bundles, and the formation process is as follows: collagen molecules → protofibrils with a diameter of 1.2 ~ 1.7nm → a diameter of Sub-fibrils of 3-5nm → fibrils with a diameter of about 20nm → thin fibers with a diameter of 2-5μm → collagen fiber bundles with a diameter of 20-150μm. The state of collagen fibers in leather is: collagen fiber bundles are sometimes divide...

Problems solved by technology

[0008] The first object of the present invention is to provide a core-spun yarn with collagen fiber bundles as the cortex, to solve the problem that the prior art extracts collagen fiber bundles from leather and directly spins them to achieve basic tensile strength, and solves the problem of high processing speed. Disadvantages that the yarn counting is extremely difficult or cannot be processed at all

[0009] The second object of the present invention is to provide a core-spun yarn with collagen fiber bundles as the cortex, so as to solve the problem that the prior art extracts collagen fiber bundles from leather and directly spins them to achieve basic tensile strength, and solves the problem of high processing cost. Spinning is extremely difficult or can not be processed at all, solve the disadvantages of spinning with other textile fibers and using the existing technology, so that the product can not give full play to the excellent performance of collagen fiber bundles

[0010] The 3rd purpose of the present invention is to provide a kind of processing method of the core-spun yarn that uses collagen fiber bundle as cortex, utilizes the method of the present invention, to solve the problem that existing technology extracts collagen fiber bundle from leather and directly carries out spinning and can not reach basic Excellent tensile strength, to solve the shortcomings of extremely difficult or impossible to process high-count yarns, and to solve the shortcomings of using existing technology to spin yarns mixed with other textile fibers, so that the product cannot fully exert the excellent performance of collagen fiber bundles
