섬유의 미세구조 및 형태가 수지가공된 셀룰로오즈 섬유의 성질에 미치는 영향 = Effect of Fine Structure and Morphology on the Properties of Resin Treated Cellulosic Fibers

다국어 초록 (Multilingual Abstract)

Viscose rayon filaments and cotton fibers were treated with dimethyloldihydroxyethyleneurea(DMDHEU). The cotton was also slack mercerized before DMDHEU application. At a given DMDHEU content the water retention values of the viscose rayon and mercerized cotton were roughly the same, even though their fine structures differed. Their water retention values were higher also than that of the nonmercerized cotton. The tenacity of the nonmercerized and mercerized cotton fell with increasing DMDHEU content whereas that of the viscose rayon increased initially. These results are attributed to different fracture mechanisms due to the dissimilarities in fine structure and morphology of the fibers. For all three fibers the breaking twist angel(BTA) increased with increasing DMDHEU content. It is suggested that the mechanism of rupture in this case is similar for all three fibers. For the same BTA value, the toughness of the viscose rayon fibers appeared to be higher than those of cotton or mercerized cotton.
