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

摘要

A non-porous inorganic ceramic containing a silver compound and a zirconium compound is added to a polypropylene resin to prepare a polypropylene masterbatch. The polypropylene masterbatch and the general nonwoven fabric The amount of the metal ion contained in the non-porous inorganic ceramic is 2 to 50% by weight. The polypropylene resin used in the preparation of the polypropylene master batch is a powdery material having an average particle size of about 200 m And 0.15% by weight, 0.1% by weight and 0.15% by weight of antioxidant, calcium stearate and peroxide are added to the polypropylene powder, respectively, to prepare a polypropylene long-fiber nonwoven fabric excellent in antibacterial and antifungal property /RTI
