SPUNBONDED NONWOVEN FABRIC AND PRODUCTION UNIT THEREFOR EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To obtain a spunbonded nonwoven fabric composed of a high-melting monofilament and a two-component filament, with the weight ratio along the perpendicular section from one surface to the other surface changing smoothly. SOLUTION: This spunbonded nonwoven fabric is composed of a high-melting monofilament and a two-component filament. The two-component filament is made up of sheathing material 2 consisting of a tacky polymeric material and core material 1 consisting of polyethylene terephthalate higher in melting point than the sheathing material 2, and for the weight ratio: the monofilament/ two-component filament, the proportion of the two-component filament changes over the range of 1 to 100wt.% along the perpendicular section of the spunbonded nonwoven fabric from one surface to the other surface of the nonwoven fabric and the weight ratio changes on the perpendicular section without developing any identifiable phase boundary.
