Abstract
A chitin-modified polypropylene spunbond non-woven fabric and a preparation method of the chitin-modified polypropylene spunbond non-woven fabric are provided. The chitin-modified polypropylene spunbond non-woven fabric contains a modified chitin in a weight percentage range of approximately 0.2%-1.5%. The modified chitin includes chitin modified by a modifier including 2-hydroxybenzimidazole, cellulose acetate butyrate, and adipic acid dihydrazide. The chitin-modified polypropylene spunbond non-woven fabric has an anti-mold grade less than 1, and an antibacterial rate greater than 9.5%.
Claims8
A preparation method of a chitin-modified polypropylene spunbond non-woven fabric, comprising:
- adding polypropylene and modified chitin with a weight percentage range of approximately 0.2%-1.5% to a horizontal double ribbon mixer;
- heating the polypropylene and the modified chitin to a temperature of approximately 40° C.-80° C.;
- mixing the polypropylene and the modified chitin for approximately 20 min-40 min;
- adding polyethylene glycol, polyvinylpyrrolidone and antioxidant;
- heating polypropylene, the modified chitin, polyethylene glycol, polyvinylpyrrolidone and antioxidant to a temperature of approximately 180° C.-190° C.;
- mixing polypropylene, the modified chitin, polyethylene glycol, polyvinylpyrrolidone and antioxidant for approximately 20 min-40 min to obtain a mixed material liquid;
- pressing the mixed material liquid into a spinning box;
- obtaining a fiber net by spinning, cooling the box by side blowing, and pulling;
- and
- hot-rolling the fiber net into a fabric by a hot-rolling machine to obtain the chitin-modified polypropylene spunbond non-woven fabric.
