| Abstract;Morphology of high-pressure steamed cellulose fabrics were investigated using viscose rayon fabrics. Viscose rayon fabrics were steamed at several conditions without (dry-condition) and with (wet-condition) excess water. X-ray diffractometry revealed that the total crystallinity increased with generating cellulose IV. There were no dependences whether dry- or wet-steaming in their crystal forms. It is suggested that cellulose IV is generated from paracrystalline structure in the amorphous region. Further, steamed rayons were dyed by 5 kinds of reactive dyes to analyze the amorphous region. The relative color depths (K/S value) compared with the control were much decreased in dry-steamed viscose rayons whereas there was a slight difference in wet-steamed ones. The excess water at steaming showed a strong role to control the structure of the amorphous region. (author abst.) |
