Caracterización del poliéster mediante un parámetro termodinámico obtenido o partir del tiempo crítico de disolución.

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


An excellent linear correlation between ln(1/TCD) and 1/T (°K^-1) has been found in this research work.
The apparent overall activation energy of the break-up process of the fibre structure, taking places in TCD test, has been calculated from the curve relating the variables studied. This new parameter has proved very sensible to the different industrial heat treatments applied to a given polyester substratum. This activation energy may be a useful parameter to characterize as a whole the fine structure of the fibre.
