Abstract

The invention discloses ultra high molecular weight polyethylene core spun yarn and a processing method thereof. Ultra high molecular weight polyethylene filaments serves as yarn for the core spun yarn, and ultra high molecular weight polyethylene chopped fibers evenly cover the ultra high molecular weight polyethylene filaments to form the core spun yarn. Due to the ultra high molecular weight polyethylene filaments, the core spun yarn has the advantages of being high in strength, resistant to abrasion and corrosion and low in density, the fabric forming performance is improved, the yarn touch and style are improved, spun yarn can serve as a stab-resistance armor fabric, an anti-cutting glove, various ropes and a fishing net and the like, and the product application range is expanded.

Description

technical field [0001] The invention belongs to the technical field of new material yarns, and in particular relates to an ultra-high molecular weight polyethylene core-spun yarn and a preparation method thereof. Background technique [0002] Ultra-high molecular weight polyethylene fiber has superior physical and chemical properties, and its characteristics are: (1) Low density: 0.97 / g·cm -3 Lighter than water, it can float on water. (2) High strength: tensile strength>3.00GPa, specific strength>3.09N·tex -1 , Higher than aramid and carbon fiber. (3) Chemical corrosion resistance: seawater resistance, strong acid resistance, strong alkali resistance, and organic solvent resistance. (4) It has the ability to resist ultraviolet rays. The industrial application products of ultra-high molecular weight polyethylene fibers are mainly filament products: products include UD cloth for bulletproof, anti-stab clothing fabrics, cut-resistant gloves, various types of ropes, fi...
