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...

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...

Polypropylene non-woven fabric is a kind of non-woven fabric that is harmless to the human body, and has simple process flow and large output. Therefore, it is widely used in various fields such as sanitary materials. So what can polypropylene non-woven fabrics be used for? 1. Polypropylene non-woven fabric can be widely used in shopping bags, gift bags, handbags, material bags, carpets and base f...

Melt blown cloth is mainly made of polypropylene, and the fiber diameter can reach 1 to 5 microns. There are many voids, fluffy structure, and good anti-wrinkle ability. These ultra-fine fibers with unique capillary structure increase the number and surface area offibers per unit area, so that the meltblown cloth has good filtration, shielding, heat insulation and oil absorption. . It can be used ...

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...

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...

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...
