Abstract: | Conclusions The cellulose triacetate-polycarbonate emulsion polymer system has been investigated.It has been found that CTA-PC solutions are less structured systems and are characterized by lower values of effective viscosity and apparent activation energy of viscous flow as compared with CTA solutions, which affords the possibility of raising the concentration of a spinning solution to 21% by wt.It has been shown that the physicomechanical properties of fibres and yarns have a tendency to become increased, thereupon the resistance to abrasion rises 2.5-fold.The CTA-PC polymer emulsion presents interest from the point of view of developing a method for the preparation of dull yarns.Translated from Khimicheskie Volokna, No. 5, pp. 45–47, September–October, 1988. |
