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 deg.C melting point and >=2.5g/denier single fiber strength and thermally fusible binder fiber.
