STRETCHABLE NONWOVEN FABRIC

摘要

PROBLEM TO BE SOLVED: To provide a stretchable nonwoven fabric having a still higher stretchability as compared with those of conventional stretchable nonwoven fabrics. SOLUTION: This stretchable nonwoven fabric includes an elastic fiber including a styrene-based elastomer and another elastic fiber and/or non-elastic fiber different form the elastic fiber. A component resin of the elastic fiber including the styrene-based elastomer has a melt viscosity of 100 to 700 Pa s at 230°C, and a melt tension of 0.2 to 2.0 cN. The elastic fiber including the styrene-based elastomer consists only of the styrene-based elastomer or includes the styrene-based elastomer and another thermoplastic elastomer.
