COPOLYESTER FIBER LAMINATE HAVING SHAPE MEMORIZING ABILITY

摘要

PURPOSE: To obtain a fiber laminate having shape memorizing ability, providing nonwoven fabric or solid fibers returning to a shaped state by low level heating even in form collapse when binder fiber is fused to a high temperature and the fiber laminate is formed once. ;CONSTITUTION: A yarn laminate comprising copolyester fiber obtained by copolymerizing ≥6C long-chain aliphatic dicarboxylic acid, having ≥150°C melting point and ≥2.5g/denier single fiber strength and thermally fusible binder fiber.;COPYRIGHT: (C)1993,JPO&Japio
