Abstract

The invention relates to a manufacturing method of moisture-absorbing and anti-static polypropylene fibers, and belongs to the technical field of polymeric fiber manufacturing. The method comprises the steps that halloysite nanotubes, conductive mica powder, attapulgite crystals, an aqueous sodium bicarbonate solution and calamine powder are mixed, subjected to a steaming reaction and vacuum-microwave radiation and then soaked in a sulfamic acid solution to thoroughly absorb the solution, ultrasonic dispersion is conducted, suspended matter is subjected to microwave plasma etching treatment and ultrasonic treatment, supernatant suspended matter is taken to be filtered, washed and dried, an obtained material is stirred in a mixer together with kieselguhr, aluminum-doped zinc oxide nanometer powder, sodium bentonite, a PP-g-MAH compatibilizer and a silane coupling agent alcoholic solution, isotactic polypropylene powder is added after the mixture is dried, and then stirring and drying are conducted. According to the method, the polypropylene fibers are prepared by blending and mixing isotactic polypropylene through the super-high adsorptive property of the halloysite nanotubes and kieselguhr and the synergistic effect of sodium bentonite and the conductive material, and therefore the polypropylene fibers have the moisture-absorbing, comfortable, dyeable and anti-static characteristics and the like.

Description

technical field [0001] The invention relates to a method for manufacturing hygroscopic and antistatic polypropylene fibers, which belongs to the technical field of polymer fiber manufacturing. Background technique [0002] Polypropylene fiber, also known as PP fiber or polypropylene fiber, is a fiber spun from isotactic polypropylene. Its biggest advantage is light weight and a density of 0.91 / cm 3 , 20-30% lighter than ordinary chemical fibers, is the smallest specific gravity of all textile fibers and has high strength, large elongation, high initial modulus, and excellent elasticity. The abrasion resistance of polypropylene fiber is only second to that of polyamide fiber, and it has good corrosion resistance, especially for inorganic acid and alkali stability, no mildew, no rot, no fear of insects, etc., but polypropylene fiber does not absorb water and is difficult to dye , the static electricity is very large, and the volume resistivity at room temperature is as high a...
