Embodiment 1

[0042] A filter layer. The method for making the filter layer includes: uniformly dispersing nanofibers with a diameter of less than 500 nanometers in water to obtain a nanofiber solution with a nanofiber mass concentration of 0.1‰, uniformly dispersing the above nanofiber solution in a filter sponge, and passing through stage microwave drying. Step get filter layer. In this embodiment, the aforementioned nanofibers are bamboo fibers.

[0043] The preparation method of the filter layer provided by embodiment 2 to embodiment 11, unless otherwise specified, is the same as the preparation method process provided in embodiment 1, and the reaction parameters and conditions of the filter layer preparation method in each embodiment are as shown in the table 1.

[0044] What needs special explanation is:

Embodiment 6

[0045] In Example 6, the carrier is a filter sponge loaded with nano-silver, and after the sponge loaded with nano-silver is immersed in the nanofiber solution, ultrasonic vibration is also used before microwave drying.

Embodiment 7

[0046] In Example 7, the carrier is a composite material of sponge and non-woven fabric, and after the sponge loaded with nano-silver is immersed in the nanofiber solution, before microwave drying, ultrasonic vibration is also used in a shaker.

Abstract

The invention provides a filter layer and a mask, and relates to the field of new materials. The filter layer is compounded of nanofibers threaded into the inside of carriers of three-dimensional multi-hole structures. In the filter layer, the nanofibers threaded into the three-dimensional multi-hole structures are matched with the carriers, so that the filer layer not only maintains a certain porosity but also has the advantages of mall resistance and good filtering effect. The mask made of the filter layer combines the advantages of high respiration comfort and high filtering performance.

Description

technical field [0001] The invention relates to the field of new materials, in particular to a filter layer and a mask. Background technique [0002] With the rapid development of my country's economy, environmental problems are becoming more and more severe, especially smog. According to statistics, the number of new lung cancer patients in my country is as high as 700,000 every year, and the excess mortality rate caused by PM2.5 is as high as 0.9‰, which is ten times that of traffic accidents. The number of people affected by smog, PM2.5 and other disasters is as high as 800 million, and the market capacity of respiratory protection products that promote growth is as high as 10 billion yuan. [0003] People usually use masks to alleviate the adverse effects of various air pollution on the human body. Among them, air filter materials can prevent particles and pollutants from entering the human body, and play an important role in reducing the damage of inhaled particles to...
