In recent years, non-woven fabric manufacturers have sprung up like bamboo shoots after a rain, and almost all regions, counties and cities across the country have built non-woven fabric factories. Although the market and policies are advantageous, the rush of manufacturers will inevitably bring about increasingly severe market competition, and various survival methods such as price wars and raw m...

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...

Face masks are generally made of multilayer non-woven fabrics: spunbonded non-woven fabrics or hot rolled non-woven fabrics + meltblown non-woven fabrics + spunbonded non-woven fabrics (SMS structure). The middle M layer meltblown non-woven fabric is a kind of non-woven fabric. The main raw material for the production of melt-blown non-woven fabrics is melt-blown grade PP. Its performance characte...

Both non-woven and meltblown masks have their own advantages, but in terms of protection, meltblown masks are better. The middle layer of the medical mask is a melt-blown non-woven fabric, which can filter bacteria and viruses in the droplets, and is a kind of ultra-fine electrostatic fiber cloth. The role of masks containing meltblown cloth: The main material of medical masks with virus filtering...

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...

Due to the impact of the epidemic, the demand for melt blown cloth remains high. However, so far, there have been a large number of unqualified melt blown cloths on the market. In order to facilitate enterprises to understand, we briefly summarize several major melt blown cloth testing items: 1. Filtering power The air extracted from the melt blown cloth detected by the particulate detector is equ...

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...

This question is the most frequently asked by mask manufacturers. We have compiled the information and discussed with you what is meltblown electret treatment. Electret refers to a dielectric material with long-term charge storage function. It has the advantages of high efficiency, low flow resistance, antibacterial, and energy saving. On the basis of ensuring the physical collision blocking effec...

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...
