The Effect of Benzyl Alcohol on the Physical and Dyeing Properties of Poly(ethylene terephthalate) Filaments

The effects of aqueous solutions of benzyl alcohol on the physical and dyeing properties of poly(ethylene terephthalate) filaments have been examined. The effects observed are dependent upon the mechanical history of the filaments. Their dyeing properties are more sensitive to changes in the molecular order of the filaments than are density and birefringence. There is not necessarily a simple relationship between the dyeing transition temperature and the glass transition temperature
