On the barking test of the cotton stalks, authors had suggested that the ultization values of the Gossypium hirsutum, L. 's barks for the source of cellulosic fabrics are superior than Gossypiumarboeum, L. in part I. And in part II, authors reported that the biochemical characteristics of the bast fibers were manifested by the Honda's rational proximate analysis of the Gossypium HirusutumL..<BR>In this report, we digested the barked cotton stalks with kraft cooking liquor. With these cooking experiments, however, could not investigate optimum cooking condition, we gained the pulps, which are similar to semichemical pulps. Although the cookings were insufficient, those unbleached pulps are bleached well by multistage bleaching.<BR>By the purpose of the utilization of pulps, such as rayon pulps or paper pulps, we should select the process of multiple bleaching. Then, if we control the bleaching condition in multistage bleaching, would gain characteristic bleached pulp from the unbleached kraft pulp. And these data of the cookings and the bleaching are showed in figures and tables.
