Introduction of Reusable Masks for Children

This article mainly introduces the difference between disposable mask and reusable mask. This reusable children mask can effectively reduce the waste of resources.


Introduction of Reusable Masks for Children

In the masks worn by children, for safety performance, the children's masks should cover the mouth, nose, and jaw safely and firmly, there should be no sharp tips and edges that can be touched, and the vision should not be significantly affected. The raw materials of masks shall not use recycled materials and materials that can cause adverse reactions, and shall not be bleached with chlorine. The child's skin is relatively delicate, so the mask can easily affect the child's skin when it is close to the skin, so high-quality fabrics are used in the material.

The difference between masks

Children's buckles are not the same as disposable masks to resist the virus. Disposable masks have an adsorption function for viruses, and the reason is on this layer of melt blown cloth. Melt blown cloth relies on electrostatic adsorption to play a filtering role. Once the adsorption is almost the same, the mask has no protective effect. Moreover, melt blown materials will age during use and cannot be used for a long time.

Reusable masks are composed of three layers, which are different from disposable masks. Disposable masks play the role of blocking dust and viruses through the principles of physical barrier and electrostatic adsorption. Disinfection methods such as high temperature, alcohol, and rays will damage the inner structure of the melt blown cloth, causing it to lose its filtering effect, so ordinary masks cannot be reused.


Development of reusable masks

The key to reusable is to find antibacterial and bactericidal materials or filter materials that can withstand traditional disinfection methods, so Xinni has made a solution to this problem. In terms of scientific and technological principles, disposable melt blown cloth masks mainly rely on electrostatic adsorption of fine germs. The reason for one-time use is that germs are adsorbed on the outer layer of the mask and cannot kill germs, so they should be replaced once not used. As long as the sterilization problem is solved, the mask can be reused. Through research, a nanofiber microporous film that replaces the melt blown cloth was found. The filtration mechanism of this nanomaterials is no longer electrostatic adsorption, but direct filtration. As long as the pores are designed reasonably, the long-term filtration effect can be maintained while satisfying the air permeability, and the mask can also withstand the test of water washing after use without affecting the filtration performance. The discovery of this technology has paved the way for reusable masks, which are also made of nanofiber materials.

This mask has been tested and can be washed with water every day, and the filtration effect can still reach 99% after repeated washing 40 times.

At the same time, this reusable mask also greatly reduces the waste of resources.
