Melt-blown nonwoven fabric, and production method and device for same

摘要: The present invention addresses the problem of providing: a stable production method using fine fibers to produce melt-blown nonwoven fabric with very few thick (fused fibers) resulting from fusion thermoplastic resin fibers; and device for same. pertains characterized by comprising polyolefin having (i) an average fiber diameter 2.0 µm max., (ii) distribution CV value 60% (iii) 15 or less fused per 100 in that molted formed into is cooled supplying cooling air temperature 30°C max. both side surfaces outlet slit (31) emits high-temperature, high-speed air;
