Abstract

The invention provides ultra-high molecular weight PE yarn and a processing method of the ultra-high molecular weight PE yarn. The processing method includes the steps that firstly, ultra-high molecular weight PE filaments are bundled and processed, and filament rods are obtained; secondly, crush cutting is conducted on the filament rods, auxiliary cutting is conducted on the filament rods in the crush cutting process so that part of the filament rods can be cut off, and fiber rods are formed; thirdly, drawing, roving, spinning and stranding are sequentially conducted on the fiber rods, and the ultra-high molecular weight PE yarn is obtained. Due to the fact that in the crush cutting process, auxiliary cutting is conducted on the filament rods, part of the filament rods are cut off to obtain short ultra-high molecular weight PE fibers, and the ultra-high molecular weight PE yarn is obtained through the subsequent third step. According to the processing method, the ultra-high molecular weight PE filaments are directly made into the fiber rods, the technology is simple and convenient to conduct, and the problem that card clothing is damaged by traditional short ultra-high molecular weight fibers in the carding process is solved.

Description

technical field [0001] The invention relates to the field of yarn processing, in particular to an ultra-high molecular weight polyethylene yarn and a processing method thereof. Background technique [0002] Ultra-high molecular weight polyethylene fiber, also known as high-strength and high-modulus polyethylene fiber, is a world-recognized high-performance fiber, mainly filament products, such as UD cloth, ropes, etc., used in bulletproof, navigation, sporting goods and other fields. Ultra-high molecular weight polyethylene fiber density is only 0.97g / cm 3 , has the advantages of high strength, high modulus, light resistance, friction resistance, cutting resistance, bending resistance, acid and alkali resistance, general organic solvent resistance, etc. It is an ideal room temperature or low temperature type material. [0003] Compared with filaments, UHMWPE staple fibers and yarns have fewer applications and products. On the one hand, the strength of yarns is much lower th...
