Embodiment 1

[0047] The antibacterial non-woven fabric is made of antibacterial fiber and bamboo charcoal fiber. After the antibacterial fiber and bamboo charcoal fiber are mixed according to the mass ratio of 10:3, they are opened by an opener, carded by a carding machine, and then thermally bonded and reinforced or watered. The thorns are reinforced into a uniform fiber layer to obtain antibacterial non-woven fabrics;

[0048] Wherein, the antibacterial fiber is prepared by the following method:

[0049] S1. Add dry cotton fibers and a certain amount of 4-bromobutyryl chloride to chloroform, heat, seal and stir at 48°C for 120 minutes, centrifuge, wash and dry after the reaction to obtain pretreated cotton fibers;

[0050] Wherein, the ratio of the amount of cotton fiber, 4-bromobutyryl chloride and chloroform is 10g: 2g: 35mL;

[0051] S2. Add the pretreated cotton fibers obtained in step S1 together with polyethyleneimine into an aqueous ethanol solution (the mass fraction of the aque...

Embodiment 2

[0056] The antibacterial non-woven fabric is made of antibacterial fiber and bamboo charcoal fiber. After the antibacterial fiber and bamboo charcoal fiber are mixed according to the mass ratio of 10:4, they are opened by an opener, carded by a carding machine, and then thermally bonded and reinforced or watered. The thorns are reinforced into a uniform fiber layer to obtain antibacterial non-woven fabrics;

[0057] Wherein, the antibacterial fiber is prepared by the following method:

[0058] S1. Add dry cotton fibers and a certain amount of 4-bromobutyryl chloride to chloroform, heat, seal and stir at 50°C for 110 minutes, centrifuge, wash and dry after the reaction to obtain pretreated cotton fibers;

[0059] Wherein, the ratio of the amount of cotton fiber, 4-bromobutyryl chloride and chloroform is 10g: 3g: 45mL;

[0060] S2. Add the pretreated cotton fibers obtained in step S1 together with polyethyleneimine into an aqueous ethanol solution (the mass fraction of the aque...

Embodiment 3

[0071] The middle layer is prepared by the following method:

[0072] 1) Under 200r / min mechanical stirring, dissolve 1g of benzoyl peroxide in 12mL of ethyl benzoate, and add it dropwise to the mixture of 45mL of water and 2g of emulsifier (sodium dodecylbenzenesulfonate) In the liquid, stir to form a complex emulsion;

[0073] 2) Add 3-propenyl-5,5-dimethyl-hydantoin into distilled water according to the solid-to-liquid ratio of 1g:26mL, stir until dissolved, then mix with the complex emulsion according to the volume ratio of 1:1, and stir evenly , to prepare the finishing solution;

[0074] 3) Finish the melt blown cloth with finishing liquid. The finishing process is double dipping and double rolling (150% liquid volume). After finishing, bake at 105°C for 2 minutes, then raise the temperature to 145°C and bake for 2 minutes, and rinse with water Wash 3 times, and finally bake at 105°C for 110 minutes, put it in a dryer to dry to constant weight, and obtain the middle me...

Abstract

The invention discloses an antibacterial mask. The antibacterial mask comprises a mask surface layer, a middle layer and a mask inner layer which are sequentially arranged from outside to inside, themask inner layer makes direct contact with the skin of a human body, the space between the mask inner layer and the mask surface layer is filled with the middle layer, a mask body is formed by the mask inner layer and the mask surface layer, mask tying belts convenient to wear are sewn on the mask body, the mask inner layer and the mask surface layer are both made of an antibacterial non-woven fabric, and the middle layer is made of a modified melt-blown fabric. The antibacterial non-woven fabric is prepared from the antibacterial modified cotton fibers and the bamboo charcoal fibers, the prepared mask surface layer and the mask inner layer not only have skin-friendly and comfortable touch feeling, but also have good antibacterial and negative ion penetrating performance and the like, andthe middle layer of the mask is made of a melt-blown cloth subjected to modified finishing, so that the middle layer has certain sterilization performance while meeting the good filtering performanceof the mask, and the antibacterial performance of the mask is further improved.

Description

technical field [0001] The invention belongs to the field of mask processing, and in particular relates to an antibacterial mask and a preparation method thereof. Background technique [0002] The deterioration of air quality, the spread of viruses and germs, and the spread of respiratory diseases have made masks extremely high in protection. Masks have played an important role several times in preventing and blocking the spread of germs. At present, ordinary masks circulating in the market are generally made of absorbent cotton gauze or non-woven fabrics, which block most of the dust particles with large particle sizes suspended in the air, and cannot effectively prevent PM2.5, antibacterial and antiviral effects . At the same time, a large number of bacteria will exist in relatively closed or poorly ventilated places. The mask covers the mouth and nose area, breathing or talking, etc., producing a large amount of water vapor and bacteria, which are easy to contaminate th...
