Production method of polypropylene long-fiber nonwoven fabric excellent in antibacterial and antifungal property

摘要

The present invention relates to a method for producing a polypropylene long-fiber nonwoven fabric excellent in antibacterial and antifungal properties containing inorganic antibacterial agent, zinc stearate and ultraviolet stabilizer for reducing screw friction, increasing melt index, and improving pigment and dendritic compatibility. (A copper / zinc compound 8 to 10 weight ratio of 6/4 to 5/5 by weight, 5 to 10 weight%, and 6.0 weight% or more of silver 90 to 95 weight%) containing copper, a zinc compound and a zirconium compound A mixed polypropylene masterbatch was prepared by mixing the polypropylene masterbatch and a general nonwoven polypropylene resin so that 0.1 to 10 wt% inorganic ceramic was contained in the final nonwoven fabric, Thereby producing a long-fiber nonwoven fabric.
