In this work, changes in the structure of polyester [poly(ethylene-terephtalate) (PET)] fibers after annealing at constant temperature (120 and 140ЊC) and different times were studied interferometrically. The density of annealed PET fibers were measured by a system based on vibrating string. The Plu
