(Summary description)The main material of meltblown non-woven fabric is polypropylene, which is a kind of ultra-fine electrostatic fiber cloth, which can capture dust. When the droplets containing pneumonia virus come close to the meltblown non-woven fabric, they will be electrostatically adsorbed on the surface of the non-woven fabric and cannot penetrate. This is how this material isolates germs. After the dust is captured by the ultra-fine electrostatic fiber, it is very difficult to be removed due to washing, and washing with water will also destroy the electrostatic dust collection ability. Therefore, this mask can only be used once.

The main material of meltblown non-woven fabric is polypropylene, which is a kind of ultra-fine electrostatic fiber cloth, which can capture dust. When the droplets containing pneumonia virus come close to the meltblown non-woven fabric, they will be electrostatically adsorbed on the surface of the non-woven fabric and cannot penetrate. This is how this material isolates germs. After the dust is captured by the ultra-fine electrostatic fiber, it is very difficult to be removed due to washing, and washing with water will also destroy the electrostatic dust collection ability. Therefore, this mask can only be used once.


The meltblown process is a polymer extrusion nonwoven process. As a common way to use PP materials, the meltblown non-woven fabric produced is commonly known as the heart of a mask. It is the filter layer in the middle of a medical mask, which can filter bacteria and prevent the spread of germs. Its fiber diameter is only one-thirtieth that of a human hair. Although the raw materials are all polypropylene, there is a big difference in the production process and performance between the special materials for melt blown cloth and other non-woven materials. The special materials for melt blown cloth require that the raw materials must meet the high melt index (>1000g/10min) and molecular weight Narrow distribution.

 

 

Kidd uses polypropylene as the base material and uses special additives to make the additives uniformly dispersed in the masterbatch. In the spinning process of meltblown cloth, adding 2%-5% can effectively increase the meltblown non-woven fabric. The density and depth of the charge trapping energy trap in the cloth can improve the comprehensive filtration efficiency and thermal attenuation resistance of the meltblown non-woven fabric. Under the condition of the same fiber fineness and gram weight, it can reduce the resistance of non-woven products and improve the filtration efficiency of non-woven products.
