Description

Elastic multi-layer bonded tissue daily anti-haze mask filter material

technical field

The invention belongs to the technical field of textiles, and in particular relates to a daily anti-smog mask filter material with elastic multi-layer knotted tissue and a weaving method thereof.

Background technique

Factors such as industrial production, automobile exhaust emissions, and infrastructure construction have polluted the atmospheric environment to a certain extent, especially in northern areas where smog frequently occurs. The main component of smog is fine particles. After inhaled, PM10 will accumulate in the respiratory system, and PM2.5 can be inhaled into the lungs. The smaller the particle diameter, the deeper it enters the respiratory tract. Fine particles can cause serious diseases such as respiratory diseases, lung diseases, and heart diseases, and reduce people's cardiopulmonary function, so as to affect people's life expectancy. When air pollution control cannot be achieved overnight, wearing a mask to travel is a convenient and effective method.

On April 25, 2016, the General Administration of Quality Supervision, Inspection and Quarantine and the National Standardization Management Committee issued the national standard "Technical Specifications for Daily Protective Masks", which is my country's first national standard for civilian protective masks. The standard will be officially implemented on November 1, 2016, and it has made clear regulations on the protective effect of fine particulate matter (PM2.5) and the safety performance of wearing. Not only the filtration efficiency of the mask is required, but also the tightness of the mask is required. Because even if the filtration efficiency of the filter material of the mask reaches 99%, if the sealing is not good, the protective ability of the mask will be greatly reduced.

At present, the quality of anti-smog masks sold in the market is uneven, and some masks do not have anti-smog function at all. The methods of filtering PM2.5 fine particles used by masks with anti-haze function are basically divided into simple filter type, electrostatic adsorption filter type, magnetic adsorption filter type, chemical adsorption filter type, and solution adsorption filter type. The anti-smog mask produced by 3M Company adds a layer of electrostatic fiber adsorption filter layer between the outer non-woven fabric and the inner non-woven fabric, and adds an exhalation valve. The appearance of the mask is similar to a gas mask, which is unsightly for civilian masks. . The invention patent application with application number CN201510831553.6 is a graphene oxide-based anti-smog mask, which consists of a mask filter layer, a mask belt and a nose clip. The filter layer of the main part of the mask is composed of multi-layer non-woven fabric sprayed with graphene with certain hydrophobic properties. The invention patent application with the application number CN201410111972.8 is composed of multi-layer fabrics, filter elements, ceramic sheets or magnetic materials capable of forming a three-dimensional magnetic field. The multi-layer fabric adopts Conlon fiber or antibacterial nanofiber, and the filter element is non-woven fabric or activated carbon fiber. The invention patent application with application number CN201310692963.8 is a three-layer composite fabric consisting of an outer protective layer, a middle antibacterial layer and an inner air-permeable layer. The material composition is complex and the production process is cumbersome. These masks are mainly non-woven products, which cannot be washed and used repeatedly, so that the cost of the masks is increased and the service life of the masks cannot be maximized to cause waste. Moreover, the non-woven masks basically use chemical fibers, which have poor degradation performance and will cause secondary pollution to the environment. Moreover, when the exhaled breath cannot be effectively discharged, water mist will be formed inside the mask, which makes the wearing comfort worse. The invention patent with the application number CN201520101138.0 is an anti-smog mask that is made by spraying polylactic acid electrospinning solution on the medical gauze layer and is close to the face. Although this preparation method has solved the problem of edge air leakage, it has not solved the problems of washing, disinfection and long-term use. The invention patent of application number CN201420177961.5 is an anti-haze mask composed of a terry fabric filter layer, a non-woven filter layer, an activated carbon fiber cloth filter layer, and a moisture-conducting filter layer. , disinfection and long-term use. The invention patent with application number CN201420177902.8 is actually a kind of microfiber towel fabric, and microfiber is also a material with poor degradation performance, which will cause secondary pollution to the environment.

Based on the current situation of the above-mentioned anti-haze mask, a kind of mask that can be used in an atmospheric environment, has good fit and tightness to the human face, has an anti-haze function, is comfortable and beautiful, can be washed and disinfected, can be used for a long time, and can be used for a long time. Degradable daily protective masks need to be developed to meet the needs of the market.
