Medical non-woven fabric is a fabric that does not need to be spun and woven. It is mainly bonded together directly by physical methods, so when you glue it, you will find that you cannot draw the thread from the non-woven fabric. It breaks through the traditional textile principle. Compared with traditional pure cotton woven textiles, medical non-woven fabrics are moisture-proof, breathable, flex...

The two masks are not the same, and the two masks look the same. The inner and outer layers are non-woven fabrics, but the meltblown filter layer in the middle is the fundamental difference. From the perspective of the filter layer, medical surgical masks are melt blown filter layers, and disposable masks are non woven fabrics. The meltblown filter layer is obviously more dense, and the material i...

We know that melt blown cloth is the core material on protective equipment such as masks and plays a major filtering role. In order to achieve effective filtration, the melt blown cloth needs electrostatic electret treatment, in which case droplets etc. will be adsorbed on the melt blown cloth. So if there is static electricity on the meltblown cloth, will it exist for a long time, or is it said t...

Medical non-woven packaging materials are generally SMS non-woven fabrics. The main material of this non-woven fabric is polypropylene, which is processed through multiple processes through meltblown and spunbond processes, and the microstructure is fine plastic fibers. Shrinkage after being exposed to high temperature is a characteristic of plastic items. There is no plastic that is truly resista...
