PERSISTENTLY ANTIVIRAL AND ANTIBACTERIAL NON-WOVEN FABRIC, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF

WIPO Patent Application WO/2021/190103

A1

The present invention relates to the field of functional textile materials. Disclosed are a persistently antiviral and antibacterial non-woven fabric, a preparation method therefor and an application thereof. According to the present invention, firstly, low-temperature plasma modification is performed on a non-woven fabric, oxygen-containing functional groups such as hydroxyl are generated on the surface of the non-woven fabric, at least one of substances such as 4-benzoylbenzoic acid, benzophenone tetracarboxylic dianhydride, chlorogenic acid is then grafted onto the surface of the modified non-woven fabric by means of an esterification reaction, thereby achieving the firm load of the substance on the surface of the non-woven fabric. The non-woven fabric prepared by means of the preparation method of the present invention can persistently generate reactive oxygen free radicals under the action of visible light (sunlight, lamplight and the like) and oxygen to kill viruses and bacteria, and thus has persistently antiviral and antibacterial functions; moreover, the non-woven fabric develops no drug resistance, and can be used for mass production of actively protective masks and protective suits.
