Abstract
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.
