Abstract

The invention relates to a preparation method for a double antibacterial non-woven fabric. The preparation method for the double antibacterial non-woven fabric comprises the following steps of soakingthe non-woven fabric in a solution containing zinc salt and then drying the non-woven fabric; putting the non-woven fabric in a solution containing silver salt, 2-methylimidazole and an adhesive andthen drying the non-woven fabric; and soaking non-woven fabric in a solution containing a reducing agent and then drying the non-woven fabric. According to the preparation method for the double antibacterial non-woven fabric, a ZIF-8 structure is loaded on non-woven fabric through an in-situ growth method, silver ions are introduced into the ZIF-8 structure, later the silver ions are reduced intonano silver, and the non-woven fabric with double antibacterial properties is obtained. By adopting the method for preparing the antibacterial non-woven fabric through in-situ growth, dispersion uniformity and adhesion of the ZIF-8 structure on the non-woven fabric can be ensured, and nano silver is loaded on the ZIF-8 structure, so that the problem that nano silver is prone to agglomeration whenintroduced into the non-woven fabric through the traditional method is also avoided. The antibacterial non-woven fabric obtained through the method has excellent antibacterial durability and washing resistance.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a double antibacterial nonwoven fabric and a preparation method thereof. Background technique [0002] Non-woven fabric, also known as non-woven fabric, is composed of directional or random fibers. It is a new generation of environmentally friendly materials with moisture-proof, breathable, flexible, light weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich colors, Low price, recyclable and so on. At present, the demand for non-woven fabrics in the medical and public health fields is gradually increasing, and there are high requirements for antibacterial properties. However, existing antibacterial non-woven fabrics have deficiencies in antibacterial properties. Especially in the case of repeated use, it is more difficult for traditional non-woven fabrics to achieve long-lasting washability and antibacterial properties. Contents of the invention ...
