Influencia de la temperatura y de la concentración de fenol en el tiempo crítico de disolución del poliéster.

Joaquín Gacén Guillén, J. M. (José María) Canal Arias


A study was made of the evolution of critica1 dissolution time (CDT) according to testing temperature and phenol concentration in mixtures with tetrachloroethane. An excellent linear correlation between the CDT log and the measured temperature of this parameter was observed in the first case. The CDT technique
was applied in distinguishing between: 1) a polyester yarn of normal affinity and another yarn having the same characteristics but a modified affinity; 2) six polyester yarns from different producers but textured under the same conditions.
