Problems solved by technology

This kind of material degrades for too long under natural conditions or cannot be degraded and cannot be reused or reused. In addition, some people who are prone to allergies cannot use the existing masks due to material problems. Finally, the existing masks are easy to fluff after wearing thorns, affecting wearing comfort

Abstract

The invention relates to a preparation method of environment-friendly mask paper. The preparation method employs papermaking forming principles and specifically comprises the steps of material preparation, pulping, sizing, forming, drying, dip-coating, drying, rolling and slitting. According to the invention, various fibers with plant contents of 50%-100% are applied to fibrillation treatment andthen matched with tencel fibers extracted from plants, and the manufactured environment-friendly mask paper has good air permeability and is easy to degrade.

Description

technical field [0001] The invention belongs to the technical field of novel mask paper, in particular to a preparation method of an environment-friendly mask paper Background technique [0002] A mask is a kind of sanitary product, which generally refers to being worn on the mouth and nose to filter the air entering the mouth and nose, so as to block harmful gases, odors, droplets, viruses and other substances, and is made of gauze or paper; It has a certain filtering effect on the air entering the lungs. When respiratory infectious diseases are prevalent, wearing a mask has a very good effect when working in a polluted environment such as dust; masks can be divided into air filter masks and air supply masks . [0003] And existing mouth mask internal layer is skin-friendly layer, and material is sanitary gauze or non-woven fabric, and outer layer is special material antibacterial layer, and material is non-woven fabric. This kind of material degrades for too long under n...
