Abstract
The invention relates to a quaternary ammonium salt antibacterial non-woven fabric and a preparation method thereof, and belongs to the technical field of non-woven fabrics. The quaternary ammonium salt antibacterial non-woven fabric is prepared by dipping a non-woven fabric in a composite adhesive containing epoxy type organosilicon quaternary ammonium salt for antibacterial finishing. The preparation method comprises the following steps that polyester chips serve as raw materials, dry chips are obtained through crystallization and drying, then a double-layer fiber web is obtained through melt extrusion, melt filtration, metering spinning, cooling drafting and filament dividing and lapping, and the non-woven fabric is obtained through needling reinforcement, unit web shaping and thickness control through hot rolling; dipping the non-woven fabric in the composite adhesive containing the epoxy type organosilicon quaternary ammonium salt for antibacterial finishing, and drying to obtain the quaternary ammonium salt antibacterial non-woven fabric. The composite adhesive formed by combining the epoxy type organosilicon quaternary ammonium salt and the starch is adopted to conduct antibacterial finishing on the non-woven fabric, and the obtained quaternary ammonium salt antibacterial non-woven fabric has the advantages of being stable in structure, excellent in performance and antibacterial capacity and low in cost.
