Problems solved by technology

[0002] At present, the mask body of medical masks is divided into three layers: inner, middle and outer. The inner layer is made of skin-friendly material, the middle layer is an isolation filter layer, and the outer layer is a special material antibacterial layer. The mask has certain dust-proof and bacteria-filtering functions. But it can't kill germs, but there are many germs in the hospital. At the beginning of use, the mask can show good dustproof and bacteria-filtering performance, but as the wearing time prolongs, the germs on the surface of the mask accumulate more and more, and the bacteria-filtering performance is not good. The performance will also become weaker and weaker, because the mask cannot kill the germs on the surface, and also makes the mask lose its protective performance
[0003] The existing patent document CN 108308758 A discloses a method for preparing an antibacterial mask filter, specifically disclosing that antibacterial powder is filled in the middle of two layers of non-woven fabrics that make up the mask. The fiber surface layer, the first base non-woven fabric layer, and the second base non-woven fabric layer are stitched or pressed together, and plant antibacterial powder is directly added to the patent document, which will make the mask thick and not conducive to ventilation. And the added powder is very easy to seep out, which will stimulate the respiratory system and cause respiratory system damage

Embodiment 1

[0018] A mite-removing and antibacterial non-woven medical mask is made of the following raw materials in parts by weight: flax fiber 46, chitosan fiber 20, cotton fiber 15, cupro ammonia fiber 6, and Ag-polyurethane fiber 2.

[0019] For the Ag-polyurethane fiber, heat the polyurethane particles to fully melt, heat and stir for 10 minutes, then add pentaerythritol of 2% by weight of the polyurethane, heat and stir at 110r / min for 8 minutes to improve the flexibility of the polyurethane, and then add nano-silver while stirring , the addition amount is 0.5% of the polyurethane weight, adjust the vacuum to -57kPa, keep warm and stir for 20 minutes, improve the antibacterial and strength of polyurethane, make the mask more skin-friendly, enhance the antibacterial property, and avoid the simple effect of traditional masks on bacteria The filtering effect and the bacteria on the outer surface can enhance the protective effect of the mask on the human body. Melt spinning, the linear ...

Embodiment 2

[0026] A mite-removing and antibacterial non-woven medical mask is made of the following raw materials in parts by weight: flax fiber 47, chitosan fiber 21, cotton fiber 16, cupro ammonia fiber 7, and Ag-polyurethane fiber 3.

[0027] For the Ag-polyurethane fiber, heat the polyurethane particles to fully melt, heat and stir for 13 minutes, then add pentaerythritol with 2.5% of the weight of the polyurethane, heat and stir at 120r / min for 9 minutes to improve the flexibility of the polyurethane, and then add nano-silver while stirring , the addition amount is 0.6% of the weight of polyurethane, adjust the vacuum degree to -58kPa, keep warm and stir for 25 minutes, improve the antibacterial and strength of polyurethane, make the mask more skin-friendly, enhance the antibacterial property, and avoid the simple effect of traditional masks on bacteria The filtering effect on the outer surface and the bacterial growth on the outer surface enhance the protective effect of the mask on...

Embodiment 3

[0034] A mite-removing and antibacterial non-woven medical mask is made of the following raw materials in parts by weight: flax fiber 48, chitosan fiber 22, cotton fiber 17, cupro ammonia fiber 8, and Ag-polyurethane fiber 4.

[0035] For the Ag-polyurethane fiber, heat the polyurethane particles to fully melt, heat and stir for 15 minutes, then add 3% pentaerythritol by weight of the polyurethane, heat and stir at 130r / min for 10 minutes to improve the flexibility of the polyurethane, and then add nano-silver while stirring , the added amount is 0.7% of the polyurethane weight, adjust the vacuum to -59kPa, keep warm and stir for 30min, improve the antibacterial and strength of polyurethane, make the mask more skin-friendly, enhance the antibacterial property, and avoid the simple effect of traditional masks on bacteria The filtering effect and the bacteria on the outer surface can enhance the protective effect of the mask on the human body. Melt spinning, the linear density is...

Abstract

The invention mainly relates to the technical field of mask processing, and discloses an anti-mite antibacterial non-woven medical mask. The anti-mite antibacterial non-woven medical mask is made from46-48% of flax fiber, 20-22% of chitosan fiber, 15-17% of cotton fiber, 6-8% of copper ammonia fiber, and 2-4% of Ag-polyurethane fiber; the anti-mite antibacterial non-woven medical mask is soft, comfortable, breathable and skin-friendly, can effectively remove mites and resist bacteria, the anti-mite rate reaches 98.2%, and the antibacterial rate reaches 96.4%, so that the safety and comfort ofthe medical mask are improved; firstly, the cotton fiber and 1 / 3 of the chitosan fiber are mixed and then laid flat into a net, and then hydroentangle is carried out for reinforcement, the net servesas an inner surface of the mask to directly contact the skin, so that the comfort and antibacterial performance of the mask can be improved, bacteria generated by breathing and skin are prevented from growing and accumulating on the inner surface of the mask, and the cotton fiber enhances the breathability of the mask to avoid the generation of sultry feeling.
