The present invention discloses a functionalized fiber material treated with a emulsion containing an ascorbic acid derivative which is hardly soluble in water, wherein the ascorbic acid derivative which is hardly soluble in water is preferably tetraalkylester of L-ascorbic acid. Said treatment method comprises treating a fiber material with an emulsion comprising a mixture of an ascorbic acid derivative which is hardly soluble in water, an anionic surfactant or a combination of an anionic surfactant and a nonionic surfactant, and water, wherein a concentration of the ascorbic acid derivative which is hardly soluble in water is 0.05 to 10 % by weight. The functionalized fiber material of the present invention enables a sustained discharge of the active ingredient without losing the moisture absorption and release properties possessed by the fiber.

Functionalized fiber material and method for treating fiber material therefor

Functionalized fiber material and method for manufacturing the same

A method for manufacturing improved regenerated cellulose fiber, by adding a crosslinking agent having two or more reactive functional groups in a molecule to a cellulose viscose solution and mixing, then extruding the viscose solution into a coagulation and regeneration bath, followed by applying a heat treatment, or followed by contacting obtained regenerated cellulose fiber with an aqueous solution of a crosslinking agent having two or more reactive functional groups in a molecule then applying a heat treatment.

Method for manufacturing improved regenerated cellulose fiber

A cellulose fabric having a sebum absorbing performance, which maintains its performance even after repeated washing in which a compound having a nonionic surface activity is fixed to a cellulose fabric. A sebum absorbing cellulose fabric is prepared by treating a cellulose fabric with an aqueous mixed solution of a nonionic surfactant and a cross-linking agent having glycidyl ether groups, or by treating a cellulose fabric with an aqueous solution of a glycidyl ether having a nonionic surface activity in the molecule thereof.
