POLYESTER LAMINATED NONWOVEN FABRIC AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a laminated nonwoven fabric that is good in operability in spraying by a melt-blow method and is obtained in such a manner that ultrafine fibers highly enter a filament nonwoven web layer to be integrated.SOLUTION: One of the layers is a nonwoven fabric comprising polyester filaments as constitutional fibers. The filaments have a cross-sectional shape in which substantial Y shapes are vertically and horizontally connected at the lower ends (hereinafter called as "substantial Y4 shape"). The filaments are mutually bonded by heat welding. The other layer is a layer obtained by accumulating polyester ultrafine fibers. In the laminated nonwoven fabric, both layers are integrated by part of polyester ultrafine fibers being embedded in gaps between fibers of the nonwoven fabric comprising the polyester filaments as the constitutional fibers.
