METHOD FOR PRODUCING WEB COMPRISING UNIDIRECTIONALLY ORIENTED FILAMENT AND APPARATUS FOR PRODUCING THE WEB

摘要

PROBLEM TO BE SOLVED: To produce a web comprising filaments unidirectionally oriented at a higher level by effectively utilizing a high-speed fluid jetted from a spinning means. SOLUTION: An apparatus for producing the web is equipped with a melt-blowing die 3 having a plurality of nozzles 2 extruding a molten polymer as the filaments 4 and arranged therein and slits 6a and 6b jetting hot air for attenuating the filaments 4, a conveyor 1 collecting and transporting the filaments 4 extruded from the nozzles 2 and a pair of shaking members 11a and 11b arranged under the melt-blowing die 3. The shaking members 11a and 11b are oppositely arranged and mutually connected with the nozzles 2 and the slits 6a and 6b placed therebetween to move in a shaking manner with the shafts r located on the central axial lines of the shaking members 11a and 11b as the centers.
