• The present work was undertaken in order to gain a better understanding of the chemical change occurred between cellulose and dimethylol urea during the predrying process in textile finishing with urea formaldehyde resin.　The reaction of dimethylol urea with methanol selected as a model for cellulose molecule was studied by estimating the contents of methylol, methoxyl and methylene groups in the resulting products. The results obtained were summarized as follows : In slightly acidified solutions (pH 4.0-4.5), a formation of methoxyl group mainly occurred. However, in lower pH solutions, the methoxyl group was easily splitted and converted into methylene linkage even in concentrated solutions of dimethylol urea. Thus, the formation of methylene linkage or resin formation took place predominantly under the conditions corresponding to the last stage of predrying process
