Abstract

The invention discloses an antibacterial ES fiber for a cool-feeling non-woven fabric and a preparation method of the antibacterial ES fiber. Taking superfine diatomite and stearic acid, uniformly stirring, adding polypropylene, a phosphite ester antioxidant and PE wax, and uniformly stirring to obtain a core layer mixture; taking superfine diatomite and stearic acid, uniformly stirring, adding polyethylene, a phosphite ester antioxidant and PE wax, and uniformly stirring to obtain a skin layer mixture; uniformly stirring the core layer mixture and the skin layer mixture, extruding, spinning, stretching, drying and cutting off to obtain ES fibers, soaking the ES fibers in a heat-conducting antibacterial solution for 50 minutes, taking out, and drying to obtain the antibacterial ES fibers for the cool-feeling non-woven fabric. The antibacterial solution is composed of ZnO-MOFs grafted with L-arginine and boron nitride grafted with Schiff base, so that the ES fiber fabric is endowed with good antibacterial property and heat-conducting property, heat energy can be rapidly taken away, and the ES fiber fabric can be applied to cool antibacterial non-woven fabrics.

Description

technical field [0001] The invention relates to the technical field of fibers, in particular to an antibacterial ES fiber for a cool feeling non-woven fabric and a preparation method thereof. Background technique [0002] ES fiber is a kind of composite fiber with functionality and high added value. It is extruded from two kinds of chips with different low melting points through a twin-screw spinning machine. Non-woven fabrics without adhesives can be formed, which can be used in clothing, carpets, industrial textiles and other fields. However, most of the ES fibers on the market have weak antibacterial properties, and the manufactured products are too hot to meet the production requirements of different fields. [0003] In order to solve the above problems, the present invention discloses an antibacterial ES fiber for a cool-feeling non-woven fabric and a preparation method thereof. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a k...
