With the development of the new coronavirus epidemic, masks have become daily necessities, and the use of masks has increased dramatically. As the core raw material of medical masks, melt blown cloth has become the norm in the context of the surge in demand for masks.

Introduction to melt blown cloth

General masks are mainly composed of three parts: non-woven fabric, meltblown cloth and ear wear material. Meltblown cloth is made of polypropylene as the main raw material. The fiber diameter can reach 0.5-10μm. These ultrafine fibers with unique capillary structure increase the unit The number of area fibers and surface area, so that the melt blown cloth has good air filtration. As an important isolation layer of the mask, meltblown non-woven fabric-the average diameter is micron, the cloth body is made of intertwined fibers, and the electret process is applied. The non-woven filter material has excellent filtering performance for the gas and liquid phases, and its filtering efficiency far exceeds that of conventional filtering materials. The filtering efficiency can reach 99.99%. It can block particles with a particle size of 0.3μm and effectively remove dust in the air.

What does meltblown cloth 90,95,99 mean?

These are different specifications of meltblown cloth, which can filter 90%, 95%, and 99% of non-oily particles respectively.

Meltblown cloth is the core material of the mask. The meltblown cloth is mainly made of polypropylene, and the fiber diameter can reach 1 to 5 μm.

There are many voids, fluffy structure and good anti-wrinkle ability. The ultra-fine fibers with unique capillary structure increase the number and surface area of fibers per unit area, so that the meltblown cloth has good filterability, shielding, heat insulation and oil absorption. It can be used in air, liquid filter materials, isolation materials, absorbing materials, mask materials, thermal insulation materials, oil absorbing materials and wiping cloths.

Melt blown cloth uses polypropylene as the main raw material, and the fiber diameter can reach 0.5-10 μm. These ultra-fine fibers with unique capillary structure increase the number and surface area of fibers per unit area, so that the melt blown cloth has good air filtration properties. , Is a relatively good mask material.

In large, medium and small medical institutions, in areas affected by earthquakes and floods, and in the seasons of high incidence of SARS, avian flu and viruses, melt blown filter paper plays an irreplaceable role with its strong filtering performance.
