Problems solved by technology

Although the para-aramid copolymer fibers and poly-p-phenylene benzobisoxazole fibers have the above advantages, they are difficult to crimp due to their high rigidity, especially the para-aramid copolymer fibers are more rigid and difficult to crimp , if the existing para-aramid fiber spinning process is used, if the fiber is not crimped and the fiber is spun directly according to the above spinning process, it will be difficult to form tops on the draw frame, resulting in difficulties in subsequent processes

Abstract

The present invention provides an ultra-high-strength yarn and a spinning process thereof. The yarn at least comprises a twisted thread, the twisted thread is at least composed of a first short fiber,a second short fiber and a third short fiber, and the weight ratio of the first short fiber to the second short fiber to the third short fiber is (30-70):(30-100):(30-100); and the first short fiberis prepared from aramid fiber II filaments with the breaking strength greater than 15 g / d, the second short fiber is prepared from aramid fiber III filaments with the breaking strength greater than 27g / d, and the third short fiber is prepared from PBO filaments with the breaking strength greater than 30 g / d. The yarn is prepared by blending and opening, combing, three-time drawing, roving and spinning, the preparation method has the characteristics that non-crimped short fibers are used in a semi-worsted wool spinning process, the shortcomings of difficult crimping and difficult spinning of high-strength fibers are overcome, and the strength of the prepared blended yarn is higher than 86 cN / tex.

Description

technical field [0001] The invention belongs to the technical field of textiles, and relates to a yarn production process, in particular to an ultra-high-strength yarn and a spinning process thereof. Background technique [0002] Para-aramid fiber is a high-tech material with excellent mechanical and thermal properties, and is widely used in the fields of national defense and military industry and optical cable rubber. The spun yarn prepared by using it can be used in the field of protection, such as cut-resistant and heat-resistant gloves, cut-resistant and temperature-resistant fabrics, and temperature-resistant high-strength sewing threads. [0003] CN103437013B patent provides a process for producing aramid yarn by using recycled aramid fiber 1414, which mainly controls the humidity of short fibers and the process parameters of card clothing. CN101918629B patent provides a method of blending aramid fiber or PBO fiber with high-shrinkage staple fiber to prepare high-shri...
