SynopsisEvidence is presented which justifies the use of the dyeing transition temperature (To) instead of the glass transition temperature (T,) as a reference temperature when using the WLF equation to describe the carrier dyeing of polyester film. Changes in the properties of the substrate caused by the effect of "carriers" on the molecular structure of the polymer have also been detected and a connection between the location of TD and chain folding is suggested from IR measurements.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
