This research focused on the kinetics of diethylene glycol (DEG) formation from the bishydroxyethyl terephthalate (BHET) monomer with a proton catalyst. In this study, the effect of proton concentration and of reaction temperature on DEG formation are discussed. Also, the rate equation of DEG format
## Abstract Relationship between structural parameters of poly(ethylene terephthalate) (PET) fibers, their mechanical properties, and nonisothermal sorption of disperse dyes are investigated. Influence of diethylene glycol (DEG) addition and small changes in draw ratio are studied. Mechanical prope
