Abstract
The physical properties and behaviours of the isotropic xanthate filaments during their gelatination, conversion to cellulose and drying, were studied, in relation to the means by which coagulation is brought about (coagulant, temperature, degree of ripeness of viscose). In this paper, the following are examined; shrinkage behaviours during each proce_??_, diffusion rate of regenerating solution into xanthate gel, rate of regeneration, and diffusion coefficients of solute in developing fresh and reswollen cellulose gels.
On consideration of these data, the structure of primary xanthate gel is discussed. And the present data would give some valuable suggestions respecting the orienting effects of compression during the fibre setting-up process-coagulation and first drying process.
