ABSTRACT:
This invention provides durably hydrophilic, thermoplastic fiber comprising a thermoplastic polymer, such as polyamide, polyurethane, or polyolefin, e.g., polypropylene, and a mixture of: (a) one or more fluoroaliphatic group-containing nonionic surfactants and (b) one or more nonionic, non-fluorinated, polyoxyethylene group-containing surfactants that contain between 20 and 80 weight percent polyoxyethylene. The mixture of the surfactants (a) and (b) is present in the fiber in an amount sufficient to impart durable hydrophilicity to the fiber at its surface. Durably hydrophilic films and durably hydrophilic fabrics and webs constructed from said fibers are also disclosed.
