摘要： The present invention relates to a melt-blown fiber web having improved elasticity and cohesion, and a manufacturing method therefor. The objective of the present invention is accomplished by a melt-blown fiber web comprising a thermoplastic resin which comprises 10 to 60 wt % of thermoplastic resin microfibers and 40 to 90 wt % of non-circular cross-sectional hollow conjugated staple fibers with respect to the total weight of the fiber web.

摘要： A waved meltblown fiber web of the present invention relates to a fiber web prepared by a meltblown method and is characterized by a preparation method in which a meltblown microfiber comes in contact with collection portions having different surface velocities so as to be collected. The waved meltblown fiber web of the present invention is characterized in that: a part of meltblown microfibers reaches a low velocity collection portion so as to be horizontally layered, thereby forming a horizontal fiber layer (10); another part of the meltblown microfibers reaches a high velocity collection portion of which the surface velocity is greater that of the low velocity collection portion so as to form a serpentine vertical fiber layer (20); and the upper end of the vertical fiber layer (20) becomes entangled so as to form a wave shaped wave layer (30) forming the uppermost portion of the fiber web.
