Is the superfine fiber nonwoven fabric melt-blown fabric | JINHAOCHENG

For residents, the most basic protective equipment is a mask. Because of the high requirements of the virus on the mask, the manufacturer of the respirator must have enough anti-virus materials to use this material. In the end, what kind of filtering material is the meltblown mask, follow the meltblown cloth manufacturer to know!Is the super - filament non-woven fabric melt-blown?

About melt-blown cloth

The core material of the mask is melt-blown cloth. The main material is polypropylene, whose fibers can be 1 to 5 microns in diameter.The porous structure is fluffy and wrinkle-resistant. The superfine fiber with unique capillary structure can increase the number of fiber per unit area and the surface area of fiber, so the meltblown fabric has good filtration performance, heat insulation and oil absorption performance.Applicable to air and liquid filtration materials, isolation materials, absorbent materials, mask materials, insulation materials, oil absorption materials and wipe materials and other fields.

Meltblown cloth filter material is made of polypropylene microfiber random distribution bonding, appearance white, smooth, soft, fiber fineness between 0.5-1.0μm, the random distribution of fiber provides the opportunity for thermal bonding between the fibers, so that the meltblown gas filter material has a large specific surface area and high porosity (≥75%).After high pressure electret filtration, it has the characteristics of low resistance, high efficiency and high dust tolerance.

How to identify the authenticity of meltblown cloth?

Two layers of inferior quality are easy to identify.A useful surgical mask must have three layers of spunbonded nonwoven fabric on either side and a gram-heavy meltblown fabric in the middle."A good meltblown cloth looks white rather than transparent due to its weight, and it looks distinctly different from the spunbonded non-woven fabric on both sides. To put it plainly, it looks like paper.If it looks different but obviously thin, the thinner the meltblown cloth, the less effective it will be.

Simple identification method:

First, as the name suggests, the meltblown layer melts when exposed to fire, rather than burning.Paper will burn in contact with fire.

Second, the meltblown layer has static electricity, you tear it into strips, will obviously feel the electrostatic adsorption, can also strip meltblown layer adsorption to the stainless steel.Anyone can disassemble a used mask for inspection.
