Meltblown nonwoven fabric composed of ultrafine fibers, melt-blown nonwoven fabric manufacturing method and the apparatus for manufacturing a meltblown

Particulate and excellent air permeability of the ultrafine fiber meltblown meltblown nonwoven fabric is obtained by the following, using the wire guide nozzle (1) having a plurality of fine spinning nozzle and an air nozzle of the melt-blown method, a porous of the outer peripheral portion and suction rotating suction drum (2) covering from the inside of upper and lower suction cylinder (2) of the suction cap (3a, 3b), (1) the guide wire nozzle (1) and the suction roller ( extending the interval between 2) end in a molten polymer, and the obtained polymer fibers will not actually be suppressed within the range of the vibration of the polymer fibers and the broken wire is wound, (2) the suction roller ( the spacing between the mouth-side end portion of the guide wire 2) of the outer circumferential surface of the suction cover (3a, 3b) attached to the fiber surface is set into contact with a yarn breakage or a meltblown nonwoven fabric can be sucked and removed even in the.
