Antibacterial biological isolation mask fabric capable of being disinfected and washed and repetitively used, and preparation method thereof

Abstract

The invention discloses an antibacterial biological isolation mask fabric capable of being disinfected and washed and repetitively used, and a preparation method thereof. A mask body is included; themask body is composed of an inner layer, a middle layer and an outer layer; the inner layer is made of an ultrafine fibre PP stretch yarn textured 75D yarn material; the middle layer is made of a nanometre bamboo charcoal 50 D yarn material; the outer layer is made of a silver iron antibacterial yarn 50 D yarn material; and three types of yarns form a multi-layer composite fabric through interlacing of longitude and latitude. According to the antibacterial biological isolation mask fabric capable of being disinfected and washed and repetitively used, and the preparation method thereof in the invention, the problem that the filter efficiency of a disposable protective mask is decreased and directly loses efficiency after being worn for 4 hours can be thoroughly solved; the antibacterial biological isolation mask in the invention is steady in physical structure, constant in density, and long-acting and steady in filter effect, and can be repetitively washed by water, washed by a machine,and directly disinfected by alcohol; expenditure on epidemic prevention consumption during a pandemic can be reduced immediately; the social cost can be reduced; the economic benefit can be increased; and the enterprise and individual expenditure burden can be reduced.

Description

technical field [0001] The invention relates to the field of masks, in particular to a washable and reusable antibacterial biological isolation mask fabric and a preparation method thereof. Background technique [0002] At present, the protective masks on the market are all disposable and disposable. At the same time, they rely heavily on the raw materials of melt-blown cloth, the overall investment is large, and the output cost-effectiveness ratio is low. The same is true for industrial masks. When encountering a large-scale epidemic spread, It is difficult to adjust, and it will generate more sanitation pressure and environmental pollution. The material of traditional disposable masks is made of polypropylene fiber, which is extremely difficult to degrade in the natural environment and will cause serious white pollution to the environment. Disposable traditional disposable masks may also become a new source of hidden transmission after use, leading to a sharp increase in t...

[0002] At present, the protective masks on the market are all disposable and disposable. At the same time, they rely heavily on the raw materials of melt-blown cloth, the overall investment is large, and the output cost-effectiveness ratio is low. The same is true for industrial masks. When encountering a large-scale epidemic spread, It is difficult to adjust, and it will generate more sanitation pressure and environmental pollution. The material of traditional disposable masks is made of polypropylene fiber, which is extremely difficult to degrade in the natural environment and will cause serious white pollution to the environment.

Disposable traditional disposable masks may become a new source of hidden transmission after use, leading to a sharp increase in the pressure of prevention and control
