Abstract

A method for producing a health-care polyprophylene bulked continuous filament (BCF) adopts the following steps: A, magnesium borate whisker, sepiolite and palygorskite fiber are mixed uniformly to be sintered in a vacuum furnace, are cooled and stirred in absolute ethyl alcohol through sodium hexametaphosphate to be dispersed, are subjected to plasma treatment at normal pressure and then are ultrasonically dispersed, cleaned, filtered and dried in deionized water which contains calcium stearate dispersion liquid; B, talcum powder and aluminic acid ester coupling agent are mixed and stirred; then, nanoscale tourmaline composite powder, calcium stearate propene polymer (PP)-g-maleic anhydride (MAH) bulking agent and the modified whisker mixture which is obtained in step A are added to be mixed and stirred, and polypropylene is added to be stirred at a high speed so as to obtain a modified polypropylene mixture; and C, the modified polypropylene mixture is dried and is subjected to melt extrusion in an extruding machine to spin the comfortable health-care polyprophylene bulked continuous filament which has the functions of well absorbing moisture, releasing moisture, resisting static electricity and naturally releasing negative oxygen ions.

Description

technical field [0001] The invention relates to a health-care polypropylene bulked filament (BCF), which includes tourmaline composite powder, inorganic materials, polypropylene polymer modification, etc., and belongs to the textile material manufacturing technology. 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 proportion of all textile fibers; it has high strength, large elongation, high initial modulus, and excellent elasticity; polypropylene fiber is second only to polyamide in abrasion resistance Fiber; good corrosion resistance, especially good stability to inorganic acids and alkalis; no mold, no rot, no fear of insects, etc., but there are disadvantages such as hygroscopicity, poor thermal performance, and high static electricity. [0003] The...
