Manufacturing process of antibacterial mask

Abstract

The invention discloses a manufacturing process of an antibacterial mask. The manufacturing process comprises the following steps: step 1, preparing an antibacterial layer; step 2, preparing an activated carbon fiber layer; and step 3, sewing a non-woven fabric layer, an activated carbon fiber layer, the antibacterial layer, the activated carbon fiber layer and a non-woven fabric layer which are stacked in sequence by using a hot melting edge-sewing technology to obtain a mask body, sewing the mask body and ear bands together, and arranging a plurality of nasal clamping strips at equal intervals in the upper opening edge sealing cloth roll to obtain the antibacterial mask. An auxiliary agent contains unsaturated double bonds, a fluorine-containing alkyl chain and a benzene ring, the unsaturated double bonds in the auxiliary agent can be subjected to a polymerization reaction, and the introduction of the fluorine-containing alkyl chain and the benzene ring improves the high temperature resistance of an antibacterial agent. A modifier is a quaternary phosphonium salt monomer containing unsaturated double bonds and is grafted to the surface of cotton fibers under the action of an initiator ceric ammonium nitrate to endow the cotton fibers with an antibacterial property, and chitosan is added and can be matched with activated carbon to improve the antibacterial effect in the aspect of adsorbing fine particles.

Description

technical field [0001] The invention belongs to the technical field of mask preparation, and in particular relates to a manufacturing process of an antibacterial mask. Background technique [0002] However, the existing conventional medical and civil masks cannot effectively resist fine particles, because most of them are made of non-woven fabrics or similar large-pore fibers, and tiny fine particles can still pass through the masks and enter the nasal cavity, basically No protection against fine particles. Professional-level protective masks such as N95 masks, although the effect of filtering fine particles is more obvious, but because of their thick texture and poor air permeability, it is easy to cause breathing difficulties after wearing them; especially children, the elderly, people with respiratory diseases and People with cardiovascular diseases and other special groups should carefully choose masks that are too thick and have poor air permeability.

Problems solved by technology

[0002] However, the existing conventional medical and civil masks cannot effectively resist fine particles, because most of them are made of non-woven fabrics or similar large-pore fibers, and tiny fine particles can still pass through the masks and enter the nasal cavity, basically Less protection against fine particles

Professional-level protective masks such as N95 masks, although the effect of filtering fine particles is more obvious, but because of their thick texture and poor air permeability, it is easy to cause breathing difficulties after wearing them; especially children, the elderly, people with respiratory diseases and People with cardiovascular diseases and other special groups should carefully choose masks that are too thick and have poor air permeability. Antibacterial masks currently sold on the market or reported in related patents either increase the number of layers of mask fibers or use specific processes to achieve antibacterial purposes. load antibacterial solution

There are generally technical problems that the prepared antibacterial masks have high resistance to air circulation and make breathing difficult, and the process is complicated, which increases the production cost; or the antibacterial components are not firmly combined with the base fiber and are easy to fall off, resulting in the loss of antibacterial properties of the mask
