Abstract

The invention relates to the technical field of non-woven fabrics, and provides a preparation method for an antibacterial melt-blown non-woven fabric. The preparation method comprises the following steps of (1) carrying out oxygen plasma treatment on a polypropylene non-woven fabric, and carrying out graft modification on the polypropylene non-woven fabric to prepare a modified polypropylene non-woven fabric; (2) polymerizing an amino-terminated hyperbranched polymer with propylene diamine and methyl methacrylate as raw materials, and preparing a modified hyperbranched polymer through polycondensation of carboxymethyl chitosan and the amino-terminated hyperbranched polymer; and (3) adding a copper chloride solution into a modified hyperbranched polymer aqueous solution, dropwise adding a sodium borohydride solution under nitrogen protection and ice bath conditions, carrying out impregnation treatment on the modified polypropylene non-woven fabric in the modified hyperbranched polymer aqueous solution after the reaction is finished, and drying to obtain the antibacterial melt-blown non-woven fabric. The preparation method solves a problem that the melt-blown non-woven fabric in theprior art only has an efficient filtering effect and does not have antibacterial property.

Description

technical field

[0001] The invention relates to the technical field of non-woven fabrics, in particular to a method for preparing antibacterial melt-blown non-woven fabrics. Background technique

[0002] The mask generally adopts SMS composite multi-layer structure, that is, the inner and outer layers are single-layer spunbond non-woven fabric, the middle layer is single-layer melt-blown non-woven fabric, or the middle layer is SMMS, which is multi-layer melt-blown non-woven fabric. SMMMS composite multilayer structure. The key to the filtering effect of the mask lies in the melt-blown non-woven fabric in the middle layer, which can filter micron-sized particles such as dust, microorganisms, and smog, and prevent the spread of germs.

[0003] Melt-blown non-woven fabrics are made of polypropylene with high melt index as the main raw material, melted by high-pressure hot air flow, and then use high-speed hot air to draw the polymer melt stream extruded from the spinneret hol...
