Meltblown cloth

Meltblown clothis die kernmateriaal van die masker.Meltblown cloth mainly uses polypropylene as the main raw material, and the fiber diameter can reach 1 to 5 microns. Medical masks and N95 masks are composed of spunbond layer, meltblown layer and spunbond layer. Among them, the spunbond layer and meltblown layer are all made of polypropylene PP material. There are many voids, fluffy structure, and good fold resistance. The ultrafine fibers with unique capillary structure increase the number and surface area of fibers per unit area, so that the melt-blown cloth has good filterability, shielding, heat insulation, and oil absorption. It can be used in the fields of air, liquid filtration materials, insulation materials, absorption materials, mask materials, thermal insulation materials, oil-absorbing materials and wipers.

On March 8, 2020, the State-owned Assets Supervision and Administration Commission of the State Council introduced that in the face of the demand for melt-blown fabrics for mask core materials, the State-owned Assets Supervision and Administration Commission of the State Council guided the relevant central enterprises to accelerate the construction of production lines, put them into production as soon as possible, and expand the melt-blown fabric market supply. Prevention and control provide protection. According to the SASAC Medical Materials Special Working Group, as of 24:00 on March 6, the output of melt-blown cloth of central enterprises reached about 26 tons on that day. As the new production line is completed and put into production, the output of meltblown fabrics is expected to increase substantially in the next week. SASAC and central enterprises will continue to increase their efforts to ensure the supply of medical materials such as medical mask production materials.
