Change in mechanical properties and structure of triacetate yarns under the action of vapors from active media

Conclusions The effect of vapors from solvents, such as acetone and ethyl alcohol, on the structure and properties of triacetate yarn has been investigated.Optimum conditions have been determined for the treatment of triacetate yarns with solvent vapors, with the objective of improving their physicomechanical characteristics.It has been found that orientation processes take place in triacetate fibres and yarns under the influence of vapors from certain organic solvents.Translated from Khimicheskie Volokna, No. 5, pp. 38–39, September–October, 1989.
