Common filter disc is compared with mouth mask, and filter disc of the present invention has three-decker, and outer layer is that the bamboo fibre of attachment phthalein work zinc class light-sensitive material is molten
Blown non-woven fabric, intermediate layer is electret melt spraying non-woven fabrics, and internal layer is polypropylene spunbond non-woven fabrics.Filter disc of the present invention can not only effective mistake
PM2.5 is filtered, and can effectively kill bacterium, prevent secondary pollution and uvioresistant, while will be filtered by removable adhesive tape micelle
Piece is pasted onto three-dimensional mask, disposable breathing mask and other kinds of mouth mask internal layer, can be used in combination with other common mouth masks, behaviour
Make to get up simple and practical.The present invention is the light-sensitive material sterilization antibacterial by outer layer, and antibacterial action is weak.
The content of the invention
In view of this, the purpose of the present invention is that there is provided a kind of antibacterial mask filter disc, the antibacterial in view of the shortcomings of the prior art
Mouth mask filter disc is adhered on the outside of mouth mask, and internal layer and outer layer Synergistic antimicrobial, anti-microbial property are excellent, and gas permeability and strainability are good, and
Also certain moisture pick-up properties, use is more comfortable.
To reach above-mentioned purpose, the present invention uses following technical scheme：
A kind of antibacterial mask filter disc, including double-layer structure are antimicrobial macromolecule fibrous layer and photosensitive antibacterial successively from inside to outside without
Layer of cloth is spun, the antimicrobial macromolecule fibrous layer is that polypropylene fibre melt spraying non-woven fabrics collect carboxymethyl chitosan/sodium alginate/polyethylene glycol
Blending spinning, the photosensitive antibacterial nonwoven cloth layer adheres to photosensitive antiseptic for bamboo-carbon fibre nonwoven layer.
Further, the photosensitive antiseptic is Chlorophyllin Ester or nano titanium oxide.
Further, the antibacterial mask filter disc is adhered on the outside of mouth mask.
Further, the antimicrobial macromolecule fibrous layer, is prepared by following steps：
Step 1, by polyglycol solution：Distilled water is 8-8.5 by weight：1.2-1.5 mixes mixed solvent；
Step 2, carboxymethyl chitosan and sodium alginate are added in the mixed solvent respectively, be uniformly mixed, deaeration processing, system
Carboxymethyl chitosan/sodium alginate spinning solution is obtained, the concentration of carboxymethyl chitosan is 10-12wt%, alginic acid wherein in spinning solution
The concentration of sodium is 9-11wt%；
Step 3, using polypropylene fibre melt spraying non-woven fabrics as basic unit is collected, using spinning-nozzle, the uniform spinning on basic unit is collected, is resisted
Bacterium macromolecular fibre layer.
Further, spinning condition is in the step 3：Spinning solution temperature is 25-35 DEG C, and environment temperature is 20-22 DEG C,
Relative humidity is 15-45%, and spinning voltage is 10-30kV, and the distance of nozzle to receiver board is 14-16cm, and the diameter of spinning exists
10-50 μm, the thickness for collecting spinning layer is 150-400 μm.
The beneficial effects of the invention are as follows：
1st, the present invention discloses a kind of antibacterial mask filter disc, is antimicrobial macromolecule fibrous layer and photosensitive antibacterial nonwoven successively from inside to outside
Layer of cloth, the antibacterial mask filter disc is adhered on the outside of mouth mask, and internal layer and outer layer Synergistic antimicrobial, anti-microbial property are excellent, gas permeability and mistake
Filter performance is good, and also certain moisture pick-up properties, and use is more comfortable.
2nd, antimicrobial macromolecule fibrous layer is that polypropylene fibre melt spraying non-woven fabrics collect carboxymethyl chitosan/sodium alginate/polyethylene glycol
Blending spinneret, i.e. carboxymethyl chitosan and sodium alginate are dissolved in the in the mixed solvent that polyethylene glycol compounds with distilled water and spun
Silk, the collection basic unit of spinning is polypropylene fibre melt spraying non-woven fabrics, and wherein carboxymethyl chitosan has very strong moisture-absorbing moisture-keeping performance and resisted
Bacterium performance, and sodium alginate has the functions such as moisture absorption, moisturizing, good biocompatibility, can strengthen the wettability power of mouth mask filter core, can
To absorb the steam of characteristics of contaminated respiratory droplets, reduction mouth mask is vexed wet, increases the usage comfort of mouth mask.And polyethylene glycol and distilled water compounding
It is nontoxic as mixed solvent, it is good with carboxymethyl chitosan and sodium alginate compatibility, and film forming and fibre-forming performance are good, spin
Silk effect is good.Collection basic unit is used as using polypropylene fibre melt spraying non-woven fabrics, it can be ensured that excellent filterability and gas permeability in addition.
3rd, photosensitive antibacterial nonwoven cloth layer is the photosensitive antiseptic of attachment in the middle of bamboo-carbon fibre nonwoven layer, wherein bamboo-carbon fibre without
Spin cloth specific surface area big, with microcellular structure, its gas permeability is not influenceed after adsorbing photosensitive antiseptic.What is used in the present invention is photosensitive
Antiseptic is Chlorophyllin Ester or nano titanium oxide, and wherein Chlorophyllin Ester has very strong light dynamic pasteurization effect, photosensitive antibacterial
