The fibers of recycled and virgin polyethylene terephtalate (PET) have been functionalized with three alcohols: ethanol, tetrol and polyvinyl alcohol (PVA). The chemical modifications generated by these alcohols have been relieved by spectroscopic analyses (FTIR, SEM, EDAX, XRD), calorimetric analysis (DSC) and thermogravimetric methods (TGA, DTG). The DSC analysis confirms the presence of a large amount of humidity on PET fiber after functionalizing it with PVA, and the TGA analysis offers indications on their thermal stability. The alcohols size and especially the number of hydroxyl groups influenced the tinctorial capacity; the CIE Lab Differences graphics reveal the values and positions of differences dL, da and db.
