Abstract
The present invention aims at providing a functionalized fiber material having a skin care effect enabling to sustainedly discharge a skin care component by an action of a fat and oil component such as sebum present on a skin surface of the human body, without losing a feeling or moisture absorbing and releasing properties which are possessed by a fiber. The functionalized fiber material is obtained by treating a fiber material comprising natural fiber, regenerated fiber, synthetic fiber and mixed fibers thereof with a treatment liquid in which .alpha.-tocopherol acetate is emulsified in water with a surfactant, and .alpha.-tocopherol acetate is stuck in an amount of 0.3 to 45.0 mg. A concentration of .alpha.-tocopherol acetate in the emulsified liquid for the fiber treatment is preferably 0.5 to 100.0 g/l.
