Abstract

The invention provides a mask material capable of inactivating viruses and a production line and application thereof. The mask material production line capable of inactivating the viruses comprises amelt-blown cloth production device, a melt-blown cloth feeding unit, a low-temperature compressing roller, a collecting unit, two non-woven cloth feeding units and two high-temperature gas generationunits; a melt-blown cloth outlet of the melt-blown cloth production device communicates with an inlet of the melt-blown cloth feeding unit, the melt-blown cloth feeding unit and the two non-woven cloth feeding units are located at the front end of the production line and used for conveying and heating melt-blown cloth and non-woven cloth, and the low-temperature compressing roller is located at the middle end of the production line and used for compressing the two layers of non-woven cloth and melt-blown cloth; and the collecting unit is located at the rear end of the production line and usedfor winding and collecting the prepared mask material. By means of the mask material production line capable of inactivating the viruses, effective combination of powder capable of inactivating the viruses and the melt-blown cloth can be achieved, the three layers of cloth (including the melt-blown cloth capable of inactivating the viruses) are tightly bonded together, and thus the single-layer mask material capable of inactivating the viruses is formed.

Description

technical field [0001] The invention relates to the preparation technology of meltblown cloth, in particular to a mask material capable of inactivating viruses, its production line and application. Background technique [0002] A mask is a kind of sanitary product, which is worn on the nose and mouth to filter the air entering the mouth and nose, so as to block harmful gases, odors, droplets, viruses and other substances. Traditional masks mostly use non-woven fabrics and melt-blown fabrics combined. [0003] Melt-blown cloth is the core material of masks, and melt-blown cloth is a filter material with polypropylene as the main raw material. The fiber diameter can reach 1-5 microns. These ultra-fine fibers with unique capillary structure increase the number and surface area of ​​fibers per unit area, so that the melt-blown cloth has good filtration, shielding, heat insulation and oil absorption. It can be used in air and liquid filter materials, isolation materials, absorp...
