Problems solved by technology

Conventional yarn does not affect air circulation, but due to its large mesh size, it cannot isolate fine particles such as PM2.5. In today's deteriorating environment, the haze weather can only be protected by closing doors and windows, and cannot be opened for replacement. Air, if you want to make yarn from similar mask materials that can isolate PM2.5 and other fine particles, the air resistance is too large to achieve the ventilation effect

Abstract

The present invention discloses a honeycomb-type air filtration yarn for doors and windows. The air filtration yarn comprises two layers of filtering faces, a plurality of orthohexagonal honeycomb-type connection passages are disposed at a connection part of the two layers of filtering faces, and each filtering face is formed by compounding a plane framework material layer at an outer layer and a high-efficiency and low-resistance air filtering material layer at an inner layer, or by compounding a plane framework material layer at an outer layer, a high-efficiency and low-resistance air filtering material layer in the middle, and another plane framework material layer at an inner layer. The honeycomb-type air filtration yarn for doors and windows is high in strength and stiffness, small in air resistance, high in air filtering efficiency, and capable of high-efficiency interception of fine particulate matters such as PM2.5 without impacting ventilation, has various functions such as energy conservation, noise prevention, thermal isolation, purification and mosquito prevention, can be used for replacing conventional screen windows and screen doors, and can be used for filtering the outdoor polluted air and then guiding the filtered air indoors, thereby maintaining good indoor ventilation.

Description

technical field [0001] The invention relates to the technical field of door and window yarn production, in particular to a honeycomb air filter yarn for doors and windows. Background technique [0002] With our rapid urbanization process, industrial and economic development, air pollution is becoming more and more serious (especially fine particle pollution such as PM2.5), especially since 2013, the smog weather mainly caused by PM2.5 pollution Invading most of the eastern part of China, important cities such as Beijing and Shanghai suffered greatly, and people's health was seriously affected. Severe smoggy weather outside makes it impossible for ordinary people to open windows for ventilation, while indoor air that is not circulated makes people uncomfortable and has a long-term serious impact on people's health. [0003] Existing screen windows and screen doors are divided into cotton gauze, polyester cloth, etc. according to their materials, and usually have fine meshes,...
