An attempt was made to prepare cotton fibers having a higher water absorbency with no changes in other textile properties, especially in handling characteristics. Such cotton fibers was successfully prepared by lightly modifying the interior of the fibers with monochloroacetic acid and 2, 3-epoxy-propanol. The optimal degree of substitution for the present purpose was in the region of 0.01 to 0.02 for carboxymethylation and 0.1 to 0.2 for dihydroxypropylation, respectively. The carboxymethylation was thus more effective than the dihydroxypropylation. The obtained cotton fibers absorbed about 150-160% as much water as the untreated fibers.
