Masks have a certain filtering effect on the air entering the lungs. To achieve a good filtering effect, the key is the core filter layer! Melt blown cloth is the most important filter material that must be used in disposable protective masks. There are a wide variety of masks on the market, and there are also various grades of meltblown. Consumers can easily buy poor quality meltblown without pay...

The protective effect of non-woven protective masks is based on the effect of adsorbing fine dust (especially dust less than 5 microns). Because dust of this size can directly enter the alveoli, it has the greatest impact on human health. General gauze masks, the dust blocking principle is mechanical filtration, that is, when dust collides with gauze, it passes through layers of barriers to block ...

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...

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...

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...

Two-layer masks are very inferior. Medical masks must have three layers. Both sides of medical masks are usually spunbonded non-woven fabrics, and the middle is meltblown fabric. A good meltblown cloth is heavy enough. It looks white rather than transparent. It looks a bit like paper. The thinner the meltblown cloth, the worse the protective effect. The melt blown layer will melt when it encounter...

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...

Many melt-blown cloth factories may have encountered this problem: the melt-blown cloth becomes brittle and hard overnight after production. At this time, should we use POE to toughen or use a softener to solve it? The production process of melt blown cloth factory price may become brittle: 1. The melting index of PP1500 meltblown material is higher or lower. The melting index is too high, and the...
