EXTENSIBLE NON-WOVEN FABRIC AND ITS PRODUCTION METHOD.

摘要

This invention relates to an extensible non-woven fabric and its production method, which non-woven fabric uses, as its raw material, a hydrogenated block copolymer comprising a polymer block A consisting primarily of a vinyl aromatic compound and a polymer block B consisting primarily of a conjugated diene compound, at least one said polymer block B being prepared by hydrogenating a block copolymer at the terminal of the polymer chain. Spinnability and non-woven fabric characteristics can be further improved by adding polyolefin to the raw material described above. The resulting extensible non-woven fabric has high strength, stretch characteristics (elongation, elongation recovery) and weatherability, and can be applied to a wide range of applications by utilizing its characteristics.
