Pure-cotton-gauze based sterile dustproof mask and producing method thereof

Abstract

The invention relates to a pure-cotton-gauze based sterile dustproof mask and a producing method thereof. A mask body consists of the pure cotton gauze, a PLA (poly lactic acid) electrostatic spinning nano-fiber film, ramie needle-punched nonwoven fabric and PLA melt-blown nonwoven fabric which are laminated sequentially from inside to outside in an ultrasonic bonding manner, wherein the pure cotton gauze is of one or two layers. The producing method includes production of 2.5g / m<2> PLA electrostatic spinning nano-fiber film and production of ramie needle-punched nonwoven fabric. The mask of the layer structure has the characteristic of guiding water from inside to outside in one way, dryness and comfort of the inside of the mask can be kept, and bacterium breeding is prevented. Therefore, the mask is sterile, capable of filtering dust effectively, and has the advantages of low production, good breathability and capability of being biodegraded completely.

Description

technical field [0001] The invention belongs to sanitary protective articles, and more specifically relates to an antibacterial and dustproof mask based on pure cotton gauze and a processing method thereof. Background technique [0002] Initially, masks were only a self-protection tool for workers in related occupations, but now as the working or living environment continues to deteriorate, for example, on June 28, 2013, the Beijing area suffered from heavy pollution, and the air in most areas was at a low level. Level 6 serious pollution, people's awareness of environmental protection and health is constantly strengthening, and masks have almost become a necessity for people. [0003] The gauze masks used by medical staff earlier have a size of 12cm*12cm and 8-12 layers. Due to the natural comfort of cotton fibers, the filter material of gauze masks is cotton yarn. Cotton gauze has good hydrophilicity, and the exhaled moisture will gather. In the fiber, the more layers of ...

Problems solved by technology

[0007] A mask disclosed in Publication No. CN102920067A is a sandwich mask of "nonwoven fabric-nanofiber film-nonwoven fabric". The nonwoven material used in the mask is ordinary nonwoven fabric, which has obvious filtering effect, but only The bacteria are intercepted, and the bacteria adhering to the mask cannot be killed, and the bacteria cannot be prevented from entering the respiratory tract

At the same time, ordinary non-woven materials (acupuncture, spunbond, meltblown) are used as the innermost layer of the mask, which cannot have a good affinity with the skin and is less comfortable
