ビスコース繊維の内部構造についての一考察

抄録

Structures of cellulose gels were studied in relation to the coagulating conditions, with the help of model filaments or films whose structures are homogeneous. The gel structure was evaluated by putting together multifarious experimental results which differ in the physical mean; lateral-order distribution, accessibility, equilibrium absorption of dye, and density. And the following interpretations were set up:
(1) In view of the multiplicity in the structural features of cellulose substances, it need hardly be considered that the structure should be examined together in both macromolecular and fine structural senses.
(2) The structure of the primary xanthate gel frame acts the decisive part upon the macromolecular structure of cellulose gel resulting from it by regeneration.
(3) The rate of coagulation seems to be of essential importance for the structure of the developing gel.
(4) The zinc xanthate gel coagulated directly by zinc ion, have a different macromolecular structure from the zinc xanthate gel prepared by immersing the ammonium or sodium gels in a solution of zine sulphate. Thus, the application of the model experimental method, such as that proposed by Briggs, should be done carefully.
