HOLLOW FIBERS AND MANUFACTURING METHOD OF HOLLOW FIBERS

摘要

A hollow fiber composed of a polymer not showing water absorbing property and excellent in lightness, dry feel and bulky feel, as well as a fiber structure containing the hollow fiber, the fiber being prepared by treating, with water, a fiber structure containing sea-island type conjugate fiber composed of a thermoplastic polymer with an equilibrium water content of 2% or less as a sea component and a water soluble thermoplastic polyvinyl alcohol polymer as an island component, and dissolving to remove the water soluble thermoplastic polyvinyl alcohol polymer from the conjugate fiber.
