Abstract
(EN)
An antibacterial non-woven fabric, comprising the following components in part by weight: 75-100 parts of polypropylene, 10-25 parts of sodium p-styrenesulfonate, 10-20 parts of a silane coupling agent, 0.15-1 part of polyhexamethylene biguanidine hydrochloride, 0.05-0.4 part of zinc salt, 1-5 parts of bamboo charcoal fibers, and 0.01-0.1 part of nanoscale fumed silica. Also disclosed are a preparation method for the antibacterial non-woven fabric and a mask with the antibacterial non-woven fabric. The antibacterial non-woven fabric is processed into an antibacterial non-woven fabric layer of a certain size to be applied into the mask for concentratedly resisting bacteria, filtering out dust particles and preventing air from passing through gaps, so that no air circulation occurs, and the effect is promoted from the structural layer that air passes through all layers of a mask body for sterilization and filtering and then enters the mouth and the nose, and the prevention effect is accordingly achieved by preventing bacteria from spreading through the air and the saliva.

L'invention concerne un non-tissé antibactérien comprenant les constituants suivants en parties en poids : de 75 à 100 parties de polypropylène, de 10 à 25 parties de p-styrènesulfonate de sodium, de 10 à 20 parties d'un agent de couplage de silane, de 0,15 à 1 partie de chlorhydrate de polyhexaméthylène biguanidine, de 0,05 à 0,4 partie de sel de zinc, de 1 à 5 parties de fibres de charbon de bambou et de 0,01 à 0,1 partie de silice sublimée nanométrique. L'invention concerne également un procédé de préparation du non-tissé antibactérien et un masque contenant le non-tissé antibactérien. Le non-tissé antibactérien est transformé en une couche de non-tissé antibactérien d'une certaine taille à appliquer dans le masque pour résister à la concentration de bactéries, filtrant les particules de poussière et empêchant le passage de l'air à travers les espaces, de sorte qu'aucune circulation d'air ne se produise, et l'effet est favorisé par la couche structurelle de telle sorte que l'air passe par toutes les couches d'un corps de masque pour être stérilisé et filtré, puis entre dans la bouche et le nez, et l'effet de prévention est ainsi obtenu en empêchant la propagation de bactéries dans l'air et la salive.
