Treating agent for hydrophilizing cotton of polyolefinic fiber
Abstract
Abstract PURPOSE: To prepare a treating agent capable of imparting durable water permeability to polyolefin-based fibers and capable of improving process passage in producing polyolefin-based hydrophilic staple fibers by mixing a treating agent including a specific quantity of an alkylolamide compound with a surfactant. CONSTITUTION: The polyolefin-based hydrophilic staple fibers are produced by mixing a treating agent for making staple fiber become hydrophilic, including >=50 wt.% alkylolamide compound of the formula (wherein, R is a 11-17C alkyl or alkenyl) with >=5 wt.% nonionic surfactant (preferably having an 11-22C alkyl or alkenyl and 3-10 mol% ethylene oxide or propylene oxide in reference to one functional group) [e.g. POE(7)stearyl ether or the like] and by imparting 0.05-0.7 wt.% treating agent to polyolefin-based fiber. The treating agent is esp. effective to conjugate fiber in which a sheath part is made of polyethylene polymer and core part is formed with polypropylene or polyester fiber.
