A kind of manufacture method of nylon conductive fiber

Abstract

The invention discloses a method for manufacturing nylon conductive fibers. The method comprises the following steps of: (1) uniformly mixing four-needle type zinc oxide crystal whisker and conductive potassium titanate crystal whisker, roasting, cooling, adding into deionized water, performing ultrasonic dispersion, filtering, and drying, and thus obtaining wrapped crystal whisker mixtures; (2) adding multi-wall carbon nano tubes into a hydrogen nitrate solution, performing ultrasonic dispersion, heating, oxidizing, cooling, filtering, drying and grinding; (3) stirring the crystal whisker mixtures, the multi-wall carbon nano tubes, stibium-doped tin oxide conductive powder, a coupling agent, polymethylene, an antioxidant and nylon sliced powder in a closed manner, and granulating the mixtures through a screw extruder, and thus obtaining nylon conductive mother particles; and (4) respectively putting the nylon conductive mother particles and polyamide 6 into the corresponding screw extruders, spraying from a composite spinneret plate, cooling and winding to obtain the nylon conductive fibers. The nylon conductive fibers have conductive characteristics and are high in processing property and spinning property.

Description

technical field [0001] The invention relates to the field of nylon fiber manufacturing, in particular to a manufacturing method of nylon conductive fiber. Background technique [0002] The vast majority of polymer materials are insulating materials, and chemical fibers made of polymer materials, such as polyester, polypropylene, nylon, etc., are also insulating, and their resistance value is 10. 13 Ω or more. During the use of these fibers, static electricity continues to accumulate, and the charge cannot be released. Eventually, it has a high potential to generate discharge, which has serious consequences for the safe production of petrochemical industry, chemical industry and other special occasions. At the same time, static electricity will also produce field effects. In the manufacture and use of high-precision instruments, it must be strictly eliminated in the electronic industry; in the civilian field, static electricity will cause electric shock when putting on and t...

AI Technical Summary

Problems solved by technology

[0007] Textiles are extensively treated with alkali in the process of weaving and printing and dyeing, and polyester conductive fibers are not resistant to alkali treatment, so the surface of polyester conductive fibers is easily damaged during the post-processing of textiles, which reduces the conductivity
