Production method of polypropylene long-fiber nonwoven fabric excellent in antimicrobial resistance and warmth

摘要

The present invention relates to an antimicrobial nonporous inorganic ceramic containing silver and zirconium in an amount of 2 to 50 wt%₂-SiO₂Based ceramics, Al₂O₃-SiO₂Based ceramics, TiO₂-Cr₂O₃Based ceramics, Al₂O₃-(Si, Ti) O₂Far infrared ray radioactive oxide ceramics having an emissivity integral value of at least 0.4 in a wavelength range of 4 to 25 selected at 500C is added to a powdered polypropylene resin having an average particle size of about 200 and an antioxidant, calcium stearate, 0.15 wt%, 0.1 wt% and 0.15 wt%, respectively, to prepare a polypropylene masterbatch. The final nonwoven fabric was then coated with 0.2 to 5 wt% of an antimicrobial nonporous inorganic ceramic and 2 to 8 wt% of a far infrared ray radioactive oxide ceramic The present invention relates to a method for producing a polypropylene long fiber nonwoven fabric having excellent antimicrobial resistance and heat retention, which is produced by mixing and spinning a polypropylene masterbatch and a general polypropylene resin for nonwoven fabric.
