In order to clarify the spinning mechanism of viscose rayon, several xanthate filaments are spun from viscoses containing amine, the internal structures of which are investigated by measuring swelling value, stress-strain curves, %-orientation-strain curves, stress relaxation, % orientation relaxation, and elastic part of deformation.
It is observed;
(1) amine has some effects upon the formation of junction points.
(2) the microstructures of xanthate filaments such as strength of junction, partial orientation of molecules derived from junction point are chiefly affected by the nature of junction point.
(3) the degree of swelling itself does not appear so closely related with these properties in our experiment.
