1.Filter material Gas filter: medical masks, room air conditioners filter material Liquid filter: beverage filtration, waterfiltration. 2.Medical & Health Material Surgical Mask: inner and outer layers with spunbond material, in the middle is melt blown fabric. 3.Environmental protection material (oil absorbent material) Meltblown nonwovens used mainly PP material. It can absorb 17-20 times bigger than its own weight of oil, in environmental protection, you can make absorption felt, oil filter, etc., are widely used in marine oil spill, plant equipment ,sewage treatment and so on. 4.Clothing Materials meltblown nonwovens by the microfiber into a net, so its very soft feel. And the fabric of small aperture,high porosity, with very good wind resistance and good air permeability, light weight, is currently doing the best material for clothing insulation materials. |
