Problems solved by technology

[0002] Ultra-high molecular weight polyethylene fiber has the characteristics of high modulus, high performance, corrosion resistance, and low density. It is one of the three high-performance fibers together with aramid fiber and carbon fiber. Molecular weight polyethylene fiber has smooth surface, small friction coefficient and poor crimp stability
These properties are unfavorable to fiber spinning, weaving, dyeing and other processing
In the spinning process, the main performances are: small cohesion between fibers, difficult yarn formation, low yarn strength, particularly prominent yarn hairiness, long hairiness, and poor yarn quality

Abstract

The invention discloses a production technology of pure spinning yarns of polyethylene fibers with ultra-high molecular weight. The production technology comprises the following steps: firstly, performing preprocessing of antistatic softening and humidification on polyethylene fibers with ultra-high molecular weight; after preprocessing, successively performing procedures of blowing-carding, first drawing, secondary drawing, coarse spinning, fine spinning and automatic spooling so as to prepare the pure spinning yarns of polyethylene fibers with ultra-high molecular weight. The pure spinning yarns of the polyethylene fibers with ultra-high molecular weight, which are obtained from the production technology disclosed by the invention, have the properties of high strength, corrosion resistance, ultra-high softness, wear resistance, and the like.

Description

technical field [0001] The invention belongs to the technical field of new material pure spinning yarn, and in particular relates to a production process of ultra-high molecular weight polyethylene fiber pure spinning yarn. Background technique [0002] Ultra-high molecular weight polyethylene fiber has the characteristics of high modulus, high performance, corrosion resistance, and low density. It is one of the three high-performance fibers together with aramid fiber and carbon fiber. The molecular weight polyethylene fiber has a smooth surface, a small friction factor, and poor crimp stability. These properties are unfavorable to fiber spinning, weaving, dyeing and other processing. In the spinning process, the main manifestations are: small cohesion between fibers, difficult yarn formation, low yarn strength, particularly prominent yarn hairiness, long hairiness, and poor yarn quality. UHMWPE fiber has been unable to be spun into spun yarn because of its high modulus an...
