摘要：

The evaluation of the long periods and crystallite lengths of original and pretreated solvent spun cellulose fibres revealed that they consist of about 90 % crystalline cellulose in the direction of the fibre axis. In the case of high wet modulus viscose fibres this percentage is only 50-60 %. The intensity of the long period of solvent spun fibres is lower than that of the high wet modulus viscose fibres corresponding to a smaller difference between their crystalline and amorphous orientation factors. There is existing a significant correlation between this difference and the intensity of the long period.
