/ Thermally bondable polyethylene/polypropylene composite fiber with high interfacial adhesive strength

摘要

PURPOSE: Polyethylene / polypropylene type thermofusing conjugate fiber has excellent interface adhesive force, thermofusing property and carding property. A manufacturing method of the fiber is characterized by mixing and spinning a little material capable of dissolving polymers of the fiber on spinning. CONSTITUTION: The material is ethylene / propylene random copolymer. The sheath-core type conjugate fiber is comprised of polyethylene as a sheath ingredient and polypropylene as a core ingredient. Rate of the ethylene is 50pts.wt. in the ethylene / propylene random copolymer. Addition quantity of the material is 1-5pts.wt. based on the core ingredient.
