Single yarn, single yarn product, and preparation method therefor

Abstract

The invention relates to a single yarn, a single yarn product and a preparation method thereof, wherein the preparation method of the single yarn comprises: converging or converging and twisting an ultra high molecular weight polyethylene thin film or strip to obtain the single yarn. The single yarn product comprises at least a body prepared from the above-mentioned single yarn. The single yarn obtained by converging or converging and twisting the ultra high molecular weight polyethylene thin films or strips in the invention replaces traditional ultra high molecular weight polyethylene fibers to develop and prepare various products. In addition to the advantages of wear resistance, impact resistance, corrosion resistance, UV resistance and the like which are similar to those of the ultra high molecular weight polyethylene fibers, the single yarn also has the unique advantages of good structural integrity, high strength, high strength utilization ratio, high production efficiency, low processing cost, light weight, small linear density and the like, and therefore the single yarn can replace the traditional ultra high molecular weight polyethylene fibers in the preparation of various products and has a very wide application range.

Problems solved by technology

As the ultra high molecular weight polyethylene fiber has a silk-like structure (the fiber number of the single yarn is about 2.5 deniers), so that in the process of preparing the various products based on the ultra high molecular weight polyethylene fiber, multiple fibers with the silk-like structures need to be arranged respectively, the process is complex, and the cost is high; and furthermore, in the preparation process of the product, the surfaces of the fibers are liable to the generation of burrs due to friction, and the fibers are liable to breaking, distortion, intertwining and other phenomena, thereby being not conductive to realizing integral uniform stress of the multiple fibers, enabling the strength of the integral strength of the prepared product to be often lower than the strength of the multiple ultra high molecular weight polyethylene fibers and realizing a relatively low strength utilization ratio.
