KF80,KF94,KF99 Meltblown

PP Melt Blown Features

KOSA Medical Department supplies filter material for face masks and respirators, the main applications are for surgical use and labor-protective use. Our melt-blown for surgical face masks meet EN14683, BFE 99% above, too. The melt-blown material for dustproof respirators meets European EN 149:2001 and American NIOSH42 CFR-84. They can be used to manufacture face mask or respirators for the grades as European standard FFP1, FFP2, FFP3, and the US Standard N95, N99, N100, R95, R99, Korea standard KF80, KF94, KF98 series.

Our melt-blown has the special characteristics of high efficiency, light weight, low resistance, long-lasting bacteria filtration, and high penetration resistance. 

These kinds of melt-blown are all eco-friendly, breathable, anti-tear, waterproof, anti-bacterial, anti-pull, mothproof. These medical mask filter material can satisfy standard EN14683:2003, ASTM F2100-2004, EN14683:2014, and will be tested by TSI 8130.

We have been exported to Russia, Taiwan, Thailand, Malaysia, Indonesia, Vietnam, Canada, Pakistan, Singapore, Portuguesa, Spain, Brazil, etc. The products can be produced according to the customer specified index.

Meltblown Non-woven Fabric Description 

Meltblown is produced in a process where polypropylene granules are melted and molten polymer is extruded through spinnerets. The continuous filaments are cooled and deposited on to a conveyor belt to form a uniform web. The calendering uses heat and high pressure applied through rollers to weld the fiber webs together at speed. This results in a soft, uniform melt-blown material.

1. Infunde the grainy type polypropylene into the pond

2. Polypropylene is conveyed to the inside of the machine body and melt

3. The melt pp will be delivered to the spinning pump and spin, fine draw, the melt pp changes into superfine fiber. The temperature of the superfine fiber is cooled by the side cold air and it will be further stretched during cooling

4. The stretched superfine fiber is transferred to the web former. Forming the embryonic form of non woven pp meltblown fabric

5. The non woven fiber web transferred to calender by net screen and will be pressed by calendar, rolling up the completed meltblown fabric rolls

6. Cut off the edges on both sides,eventually become a non woven coiled material
