MANUFACTURING METHOD OF ANTIBACTERIAL NONWOVEN FABRIC, AND ANTIBACTERIAL NONWOVEN FABRIC MANUFACTURED USING MANUFACTURING METHOD

WIPO Patent Application WO/2023/113101

A1

Provided are a manufacturing method of an antibacterial nonwoven fabric, and an antibacterial nonwoven fabric manufactured using the manufacturing method, the method allowing copper to be deposited on a calcium carbonate powder so that a copper antibacterial agent, which is relatively resistant to oxidation, is prepared and used as a material for a nonwoven fabric, and thus the present invention is advantageous for color setting of a nonwoven fabric and has excellent antibacterial properties. To this end, the manufacturing method of an antibacterial nonwoven fabric, according to the present invention, comprises the steps of: (S1) depositing copper on a calcium carbonate powder so as to prepare a copper antibacterial agent; (S2) mixing the copper antibacterial agent with a polypropylene so as to prepare master batch chips; (S3) melt spinning the master batch chips so as to manufacture a single-layer nonwoven fabric; (S4) melt spinning the master batch chips on at least one surface of the single-layer nonwoven fabric so as to manufacture a multilayer nonwoven fabric; and (S5) embossing the multilayer nonwoven fabric by means of compression rollers.
