Abstract
The differential solubility of two poly(ethyleneterephthalate) (PET) f ibres was determined in one thermally treated substrate and in another thermally untreated. In both cases, mixtures of phenol/tetrachloroeth ane with the appropriate composition were used. The non-dissolved frac tions of the untreated PET fibre display a molecular mass and a crysta llinity which increase on increase of the temperature of the different ial solubility test. In the case of the thermally treated substrate, b oth the molecular mass and the crystallinity of the residual fraction remain constant on increase of the test temperature.
