MOLTEN LIQUID CRYSTAL-FORMING POLYESTER CONJUGATE FIBER

摘要

PROBLEM TO BE SOLVED: To provide a molten liquid crystal-forming polyester conjugate fiber having a high strength and a high elasticity and also excellent in friction durability and flexing durability. SOLUTION: This conjugate fiber constituted with a molten liquid crystal-forming polyester and flexible thermoplastic polymer is provided by having 40 to 90 wt.% conjugating ratio of the molten liquid crystal-forming polyester, constituting the component for forming the surface layer of the conjugate fiber with a mixture of the molten liquid crystal-forming polyester and the flexible thermoplastic polymer and also satisfying TB>TA+10°C by taking the melting point of the molten liquid crystal-forming polyester as TA and the melting point of the flexible thermoplastic polymer as TB.
