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

Embodiment 1

[0036] Such as figure 1 As shown, an air filter yarn for planar doors and windows is composed of three layers of planar skeleton material layer 1, high-efficiency and low-resistance air filter material layer 2, and planar skeleton material layer 1. It has a sandwich structure, and the upper and lower layers are planar skeletons. Material layer, the middle layer is a high-efficiency low-resistance air filter material layer (purchased from 3M Company, model BMF-Merv12), and the thickness of the high-efficiency low-resistance air filter material layer is 0.3mm.

[0037] The planar skeleton material layer is made by mixing the following raw material components in terms of mass percentage: 10% of 15D polyester staple fiber, 40% of 7D polyester staple fiber, and 50% of 4D low melting point polyester staple fiber.

[0038]The melting point of 15D polyester staple fiber (32mm) is 256°C; the melting point of 7D polyester staple fiber (32mm) is 256°C; 110°C, and the melting point of th...

[0049] An air filter yarn for planar doors and windows, composed of three layers of planar skeleton material layer 1, high-efficiency and low-resistance air filter material layer 2, and planar skeleton material layer 1, has a sandwich structure, and the upper and lower layers are planar skeleton material layers, In the middle is a layer of high-efficiency and low-resistance air filter material (purchased from 3M Company, model BMF-Merv14), and the thickness of the layer of high-efficiency and low-resistance air filter material is 0.1mm.

[0050] The planar skeleton material layer is made by mixing the following raw material components in terms of mass percentage: 20% of 15D polyester staple fiber, 50% of 7D polyester staple fiber, and 30% of 4D low melting point polyester staple fiber.

[0051] The melting point of 15D polyester staple fiber (64mm) is 256°C; the melting point of 7D polyester staple fiber (64mm) is 256°C; 180°C, and the melting point of the core layer is 256°C....

Embodiment 3

[0062] An air filter yarn for planar doors and windows, composed of three layers of planar skeleton material layer 1, high-efficiency and low-resistance air filter material layer 2, and planar skeleton material layer 1, has a sandwich structure, and the upper and lower layers are planar skeleton material layers, In the middle is a layer of high-efficiency and low-resistance air filter material (purchased from 3M Company, model BMF-Merv14), and the thickness of the high-efficiency and low-resistance air filter material layer is 0.2mm.

[0063] The planar skeleton material layer is made by mixing the following raw material components in terms of mass percentage: 15% of 15D polyester staple fiber, 45% of 7D polyester staple fiber, and 40% of 4D low melting point polyester staple fiber.

[0064] The melting point of 15D polyester staple fiber (51mm) is 256°C; the melting point of 7D polyester staple fiber (51mm) is 256°C; 180°C, and the melting point of the core layer is 256°C.

Abstract

The invention discloses a colored air filtering gauze for planar type doors and windows. The air filtering gauze is formed by thermal laminating of planar skeletal material layers and a high-efficiency low-resistance air filtering material layer, and is of a sandwich structure in which the planar skeletal material layers are the upper layer and the lower layer and the high-efficiency low-resistance air filtering material layer is arranged in the middle. The colored air filtering gauze is high in strength and rigidity, low in air resistance and high in air filtering efficiency, can efficiently filter out PM 2.5 and other fine particles, and does not influence air circulation. The colored air filtering gauze has various functions such as energy conservation, noise prevention, thermal insulation, purification and mosquito prevention and can replace a conventional screen window or screen door, polluted air outdoors is filtered and then is introduced into a room, and indoor air circulation is maintained.

Description

technical field [0001] The invention relates to the technical field of door and window yarn production, in particular to a colored air filter yarn for plane 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 mes...
