- 摘要：
PROBLEM TO BE SOLVED: To provide an elastic filament produceable in excellent spinnability without causing yarn break and hardly causing meandering when taking the filament from a spinning nozzle, and to provide a stretchable sheet and an absorbent article using the same.
SOLUTION: The elastic filament includes a resin composition containing an A1-B-A2 triblock copolymer having polymer blocks A1 and A2 consisting essentially of a vinyl aromatic polymer, and a polymer block B consisting essentially of a polyolefin. The polymer blocks A1 and A2 have a total of weight average molecular weights of the polymer blocks A1 and A2 14,000-20,000, each measured by a gel permeation chromatography, and the weight average molecular weight of the polymer block B measured by the gel permeation chromatography is 40,000-80,000.
