Knowledge of meltblown cloth of surgical masks for medical use | JINHAOCHENG

What does medical surgical mask manufacturer recommend is meltblown cloth?

Then Jin Haocheng professional meltblown cloth manufacturer to say.

The core of the mask is polypropylene, which is composed of many crisscrossed fibers stacked in a random direction. The diameter of the fibers is 0.5-10 microns, with many voids, loose structure, good anti-wrinkle ability, and good filtration, shielding, thermal insulation and oil absorption properties.

The random distribution of fibers makes the fibers have more opportunities for thermal bonding. The filter material has larger specific surface area and higher porosity. Through high-pressure electral filtration, the product has the characteristics of low resistance, high efficiency and high dust tolerance.

The mask is usually used in three layers or more. The innermost layer is mostly made of non-woven fabric for mechanical support, and the middle layer is mostly made of meltblown fabric for filtration.Whether the mask is qualified depends largely on the meltblown cloth. The detection of meltblown cloth is mainly the particle filtration efficiency test and the bacteria filtration efficiency test

In the third-party detection of meltblown cloth, particle filtration efficiency detection and bacterial filtration efficiency detection have passed the detection.

In daily life, how to identify whether there is meltblown cloth in medical cover mask?

1. It doesn't burn when it melts with fire 

Real melt-blown cloth has a high melting point and does not burn in case of fire, whereas paper does.

2. Electrostatic adsorption

Will tear the meltblown cloth into several small strips, will obviously feel the effect of electrostatic adsorption, a mask with meltblown cloth is able to absorb scraps of paper (scraps of paper to be broken);It can also be adsorbed on stainless steel. 

The above is the knowledge of non-woven meltblown cloth mask, I hope it will be helpful to you.We are from China's professional mask supplier - Jin Haocheng, welcome to consult!
