Abstract
The invention provides deodorant rayon fibers having a superior deodorization performance. The deodorant rayon fibers are produced by implanting a large quantity of fine grains produced by milling white charcoal in a matrix of the rayon fiber. After adding and mixing a water dispersion which disperses the large quantity of fine grains into viscose solutin, and then spinning, thereby the deodorant rayon fibers are produced. The fine grains obtained by milling the white charcoal do not form spheres with smooth surfaces, but their configurations are irregular with projections. As a result, even when they are implanted in the matrix of the rayon fiber, the projections tend to be exposed on the surfaces of the rayon fibers. The exposed fine grains adsorb odor gases into themselves, thereby their superior deodoization performance is performed.
