Melt-blown non woven fabric is the core filter material of masks, which is mainly determined by the filtering mechanism of the melt-blown filter material, which is mainly divided into mechanical barrier and electrostatic adsorption. 1. Mechanical barrier Mechanical barrier has the following situations: a. Droplets with a particle size greater than 5um in the air can be blocked by the filter materi...

Elastic non woven fabric is a brand-new non woven product, which breaks the situation of air-impermeable, over-tight, and low-stretchability of elastic film materials. Elastic non-woven fabrics are widely used in some life care products. So, what are the characteristics and advantages of elastic non woven fabrics compared with ordinary non woven fabrics? Currently, there are various types of elast...

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...

Non woven fabric is a general term, because PET can also be used as non woven fabric, but PP non woven fabric limits the types of plastics. In principle, there is no difference between them. SMS is added on the basis of two spunbond production lines, a meltblown M production line. PP non woven fabrics are spunbond non woven fabrics, and PP refers to the raw materials for the production of non wove...

1. Raw materials Melt-blown PP is modified on the basis of ordinary PP. After modification, PP has higher melt fat and stable fluidity, while ordinary PP melt has uneven fluidity, and some excessive drafting may easily cause agglomerate polymerization. It makes the fiber thickness uneven and affects the air permeability and filterability of the meltblown cloth. 2. Production process Melt-blown clo...

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...

The water electret is an electret process for making the meltblown cloth electrostatically charged during the production of the meltblown cloth. The process can be that the meltblown cloth is saturated with static electricity and the electrostatic electret time is long. The reason why melt blown cloth has higher filtration efficiency is because it adds electrostatic electret technology in the prod...
