Description

Antibacterial and anti-mosquito aramid fabric and preparation method thereof
Technical Field
The application relates to the technical field of textile fabrics, in particular to an antibacterial and mosquito-proof aramid fabric and a preparation method thereof.
Background
The fabric is a material for making clothes, is one of three elements of the clothes, can explain the style and color of the clothes, and plays a key determining role in the characteristics of the clothes, and the characteristics of the clothes comprise the characteristics of comfortable wearing, sweat absorption, ventilation, stiff and smooth suspension, noble vision, soft touch and the like. Taking the protective fabric of the firefighter uniform as an example, the protective effect of the firefighter uniform on operators under high temperature or other dangerous conditions needs to be met.
The outer layer of the protective fabric in the related technology is metal foil, the base cloth is made of core-spun yarns, the core yarns are glass fiber filaments or chemical fiber filaments, the cladding fibers are made of synthetic or cotton and other organic fibers, the product obtained by the production mode is general in heat insulation performance, single-factor heat insulation protection is mainly used, protection of fire fighters under other dangerous conditions cannot be met, and great limitation is realized on the depth and the width of protection. For example, when firefighters rescue in the field and fight a forest, the firefighters can bite mosquitoes due to sultry sweating, and the mosquitoes are the transmission media of various infectious diseases, so that potential safety hazards can be brought to the operation of the firefighters, and the human health is not facilitated.
Disclosure of Invention
In order to realize the protection performance of the protective fabric on mosquitoes, the application provides an antibacterial mosquito-proof aramid fabric and a preparation method thereof.
First aspect, this application provides an antibiotic mosquito-proof worm aramid fiber surface fabric, adopts following technical scheme:
an antibacterial and mosquito-proof aramid fabric comprises an antibacterial protective layer, a base fabric layer and an insect-repelling and mosquito-proof layer which are sequentially stacked;
the antibacterial protective layer comprises the following components in parts by weight,
50-100 parts of ramie fibers;
100 portions and 250 portions of aramid fiber;
100 portions of polyurethane and 250 portions of polyurethane;
40-80 parts of an antibacterial component;
the base cloth layer comprises the following components in parts by weight,
nylon 66100 and 250 parts;
100 portions and 150 portions of high temperature resistant components;
30-50 parts of a heat insulation component;
the insect-repelling and mosquito-preventing layer comprises the following components in parts by weight,
100 portions and 200 portions of bamboo charcoal fiber;
60-100 parts of corrosion-resistant component;
50-100 parts of a flame retardant component;
15-30 parts of an anti-mosquito and insect-repellent finishing agent;
the mosquito-proof and insect-repellent finishing agent consists of pyrethrin and one or more of the following components: citric acid, carbamates, bergapten, menthyl acetate, allicin, acrylates, stearamides, and ethanol.
Through adopting above-mentioned technical scheme, because set up antibiotic mosquito-proof worm aramid fiber surface fabric into multilayer structure, thereby multiple effect has been realized to different functions of function correspondence of different layer structures, flax fiber cooperation antibacterial component that sets up in the antibiotic inoxidizing coating of inlayer can effectively absorb the sweat and reduce bacterial growing, the base cloth layer uses high temperature resistant nylon 66 as the skeleton as the intermediate level, the fire-resistant protection nature of protective surface fabric has been satisfied in cooperation high temperature resistant component and the use of thermal-insulated component, mosquito-proof expelling parasite layer passes through corrosion-resistant component as outmost, fire-retardant component, the protection scope of mosquito-proof expelling parasite inoxidizing coating is wider for the interpolation of mosquito-proof expelling parasite finishing agent, the effect is better, wherein pyrethrin the mosquito-proof expelling parasite finishing agent and fragrant citrus lactone and menthyl acetate etc. have played mosquito-proof expelling effect more stably under the promotion effect of citric acid.
