Spunbonded nonwoven fabric, method for producing the same, and method for producing molded article using the same

摘要

PROBLEM TO BE SOLVED: To provide a spun-bonded nonwoven fabric excellent in shape-holding properties after heat molding and in heat-molding properties, a method of manufacturing the same, and a method of manufacturing a molded article using the same.SOLUTION: The spun-bonded nonwoven fabric includes polyethylene terephthalate, and a thermoplastic polystyrene-based copolymer where the glass transition point of the thermoplastic polystyrene-based copolymer is 100-160°C, the content is 0.02-8 mass%, the fracture elongation after heating at 130°C for 1 minute is not less than 250%, and the 20% elongation stress after the heating is not greater than 40 N/5 cm in terms of a basis weight of 200 g/m.SELECTED DRAWING: None
