Abstract
A cellulose fiber is immersed in a cellulose fiber dissolving agent such as tertiary amine-N-oxide, lithium chloride/N,N-dimethylacetoamide or N-methylmorpholine-N-oxide under conditions where the dissolving agent does not dissolve the cellulose fiber. Therefore, the water absorbing property and moisture absorbing and discharging property of the cellulose fiber can be improved without deteriorating the strength and feeling of the cellulose fiber.
