[0030] The spinning implementation steps are as follows:

[0031] (1) Raw material selection: UHMWPE staple fiber and black polyester staple fiber with a length of 38mm and a linear density of 1.67dtex are used;

[0032] (2) Raw material pretreatment: Due to the small volume and mass of ultra-high molecular polyethylene staple fibers and low moisture regain, in order to improve the cohesion and antistatic ability of fibers and the spinnability of ultra-high molecular polyethylene staple fibers, before spinning It must be humidified preconditioning. The measure...

Abstract

The invention discloses a spinning method for ultra-high molecular weight polyethylene / black polyester staple fiber blending rough gray yarns. The blending rough gray yarns are formed by blending raw materials of ultra-high molecular weight polyethylene staple fibers and black polyester staple fibers in proper blending ratio through a compact siro spinning technology. The main steps comprise raw material pre-processing, blowing, cotton carding, drawing, roving, spun yarns, spooling, and other procedures to spin the ultra-high molecular weight polyethylene / black polyester staple fiber blending rough gray yarns. Through different blending ratios of the ultra-high molecular weight polyethylene staple fibers and the black polyester staple fibers, various kinds of rough gray yarns in different gray levels can be spun out. Special performance of high-strength, wear resistance, cutting prevention of ultra-high molecular weight polyethylene staple fibers is fully developed, and weakness of poor dyeing property of the staple fibers is overcome. The yarn has high wearing-resistance and a cotton yarn style, and can be used for production of protection fabrics, gloves, and sports socks in special industries, a later dyeing processing procedure of the product can be removed, thereby achieving an energy-saving environmentally-friendly green production requirement.

Description

technical field [0001] The invention relates to the technical field of special spinning, in particular to a compact siro spinning method using ultra-high molecular weight polyethylene short fibers and black polyester staple fibers as raw materials with a suitable blending ratio. Background technique [0002] Ultra-high molecular weight polyethylene fiber is currently the fiber with the highest specific strength and specific modulus in the world. Its specific strength is more than ten times that of steel wire with the same cross section, and its specific modulus is second only to super carbon fiber. It has chemical corrosion resistance, wear resistance, impact resistance and cut resistance, but its melting point is only about 145°C, its flame retardancy is poor, it is not easy to color, and its price is high, but it is still an ideal functional material . [0003] At present, ultra-high molecular weight polyethylene is mainly filament products, which are mainly used in milit...
