Technology transfer of the rayon pulp from Tomarioru Mill, Karafuto Industry Co. Ltd. to Noda Mill and its industrial applications in the mill by Nobuji Okuno were discussed on the basis of his unpublished data. Secret informations about the productive method of the rayon pulp based on the chlorination process in Tomarioru Mill were leaked to Okuno in Noda Mill after only about two months from the first trial in Tomarioru Mill. And adopting the chlorination process modified by Okuno, the manufacture of the rayon pulp became possible to be carried out in the mill and the pulp was put on the market in early spring 1933. The commercialization of it was supported by following conditions; a) larger demand for the rayon pulp b) high price of rayon pulp imported c) support by Kikujiro Takashima, a leader of the company d) good morphological structure of Ezomatsu fiber. By the development of the productive method of the rayon pulp several major advances were made in the technique of the pulp and paper industry in Japan; i. e., a) the chlorination process became as a matter of course as a basic technique of the bleaching and purifying processes b) introducing the chemical knowledge to the cooking and bleaching processes, more reasonable operations were carried out than before c) a distinction between rayon and paper pulps was made clear and the quality of the latter was improved.
