Problems solved by technology

[0004] The above-mentioned conventional pretreatment and cleaning methods have the following defects: the pretreatment oil can not penetrate evenly in the fiber, which affects the fiber treatment effect, so it cannot completely overcome the problems of poor cohesion and serious static electricity of the sulfone fibers. It is easy to accumulate static electricity during the production process, lack of cohesion between fibers, and easily produce holes in the process of fiber web formation, making it difficult to spun into sliver, poor yarn evenness, and low yarn strength

Abstract

The invention discloses an aromatic polysulphone / antistatic fibre mixed yarn produced in the textile industry and production method thereof as well as a loosening and mixing device adopted in the production. The aromatic polysulphone is 95-99 percent of the mixed yarn, and an antistatic fibre is 1-5 percent of the mixed yarn. In order to solve the problems of uneven permeation of a pretreatment oil agent, which is easily generated in the processing of aromatic polysulphone in a conventional cotton spinning process, and poor cohesive force and serious static electricity in the production of pure aromatic polysulphone, the novel loosening and mixing device is adopted, and the conventional cotton spinning process is improved. In the production process, an aromatic polysulphone fiber and the antistatic fibre are mixed and loosened by the self-designed mixing and loosening device and then carry out the processing procedures of coiling, cotton carding, drawing, roving, fine spinning, spooling, doubling, double-twisting and thermoforming to spin the product. The aromatic polysulphone / antistatic fibre mixed yarn produced by the processing method has even yarn stem, high strength and excellent flame retardant property and antistatic property.

Description

technical field [0001] The invention relates to a sulfonamide / antistatic fiber blended yarn produced in the textile industry. The blended yarn has dual functions of flame retardancy and conduction. The invention also relates to a method and an opening device for producing the sulfonamide / antistatic fiber blended yarn. Background technique [0002] Polysulfone fiber is a flame-retardant and high-temperature resistant fiber independently developed by my country with independent intellectual property rights. Its scientific name is polyphenylsulfone terephthalamide fiber, and it is a kind of aromatic polyamide fiber. Due to the high specific resistance of the sulfonamide fiber itself, poor fiber cohesion and poor spinnability of the fiber, it is difficult to form a yarn, thereby restricting the application and development of the sulfone fiber. The varieties of sulfonamide yarns reported in public literature in recent years mainly include pure spinning, blended yarn products of ...
