Problems solved by technology

However, there is no report about this information, especially the production of blended yarns using air-jet spinning equipment.
Due to the high elongation of aramid fiber, especially the relatively large fiber elongation of meta-aramid fiber, it is easy to produce accidental elongation into a rubber yarn state, and it is easy to block the nozzle of the air-jet spinning equipment, which affects the smooth progress of production, and is easy to The boiling water shrinkage of the yarn is too large, which affects the performance of the fabric

Abstract

The present invention is one kind of blended aramid yarn and its production process. The blended aramid yarn consists of aramid fiber 10-60 wt%, polyacrylic-polyvinyl chloride fiber 30-80 wt% and antistatic synthetic fiber 1-10 wt%, and has fiber length of 38 mm or 51 mm and spinning count of 10 s-50 s. It is produced through mixing material, producing card sliver, drawing and jet spinning. The production process includes spraying the polyacrylic-polyvinyl chloride fiber with antistatic agent, two card sliver producing modes, etc. The blended aramid yarn has excellent wear resisting property, excellent fireproof performance and high electrically insulating performance, and the fabric produced with the blended aramid yarn may be used in special suits for use in high temperature, electric welding and high voltage environment, and used in making fireproof decoration.

Description

technical field [0001] The present invention relates to the cotton spinning industry in the textile industry, and specifically refers to a kind of aramid fiber blended yarn, which is made into special-purpose blended yarn containing aramid fiber, acrylic chloride fiber and antistatic synthetic fiber by using the processing method of air-jet spinning equipment yarn. Background technique [0002] The development of science and technology is a double-edged sword. While bringing convenience and improving the quality of life to human beings, it also has a negative impact on human living and working environments. For example, in some workplaces such as high temperature and electric welding, it has brought potential hazards to the living environment of living and operating personnel. The sparks of electric welding can easily cause damage or burning of workers' clothing, which has brought hidden dangers and damage to the body. For this reason, for this situation and the demand of t...
