<p>The present invention discloses a functionalized fibre material treated with a emulsion containing an ascorbic acid derivative which is barely soluble in water, wherein the ascorbic acid derivative is preferably tetraalkylester of L-ascorbic acid. Said treatment method comprises treating a fibre material with an emulsion comprising a mixture of an ascorbic acid derivative which is barely 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 barely soluble in water is 0.05 to 10 % by weight. The functionalized fibre material of the present invention enables a sustained discharge of the active ingredient without losing the moisture absorption and release properties possessed by the fibre.</p> |
