Problems solved by technology

This filter humidification method has a good humidification effect, no scale marks are left on the furniture, and the dust in the air is effectively removed. Therefore, it is a type vigorously promoted by relevant manufacturers. However, paper products have always had some shortcomings: the antibacterial performance of paper product materials is not easy Maintain; after using for a period of time, the surface of the material is easy to scale, and the water absorption performance decreases; the strength of paper products is low in a wet state, etc.
The main function of the filter membrane made by this method is to enhance the adsorption capacity of air dust, so that it can be used for large-flow air purification, but because it does not have enough liquid absorption height, it is not suitable for air humidification and purification

Abstract

The invention relates to a nonwoven fabric for air wetting purification, wherein the nonwoven fabric for air wetting purification has a liquid-absorption height of 100-200mm and a wetting tensile strength of 3.0-8.0KN/m; preferably, the liquid-absorption height is 120-180mm and the wetting tensile strength is 5.0-8.0KN/m; and optimally, the liquid-absorption height is 130-160mm and the wetting tensile strength is 5.5-8.0KN/m. A method for preparing the nonwoven fabric for air wetting purification comprises the following steps: mixing water-absorption resin with antibacterial agent as a working solution; coating the working solution onto the nonwoven fabric by using a soaking or coating method; and drying and baking the nonwoven fabric, so as to acquire the nonwoven fabric.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a nonwoven fabric for air humidification and purification. Background technique [0002] The quality of air quality is a problem that people are generally concerned about. Since people are indoors most of the time, the harm caused by indoor air pollution is more serious than that of outdoor air pollution. In economically developed countries such as Europe, America and Japan, the application of indoor air purification devices is very common. In our country, air pollution, interior decoration pollution, etc. have made people pay more and more attention to air pollution problems. Various indoor environment air purification treatment products have emerged as the times require, and many manufacturers of such products have emerged. After more than ten years of development, a new industry has been formed ----- indoor environment purification and treatment industry. Statistics show that the sal...
