Polyester (Egyptian) fibers were annealed at constant temperature (190ะŠC) with different annealing times. Density, crystallinity, mean square density fluctuation, mechanical loss factor, and molecular orientation were calculated. Densities and mechanical loss factor were determined using an acoustic

A series of branched poly(ethylene terephthalate) samples was prepared by employing 0.07-0.42 mol % trimethylolpropane (TMP) for melt polycondensation. These polymers were characterized with respect to molar mass, intrinsic viscosity, and melt viscosity. Spinning into fibers took place at spinning s

The mechanism of thermally induced elongation in poly(ethylene terephthalate) fiber spun at 3500 m min 01 has been examined. This partially oriented fiber has a crystalline content of about 25% and a high degree of orientation. The effect of time and tension during heat treatment was examined, and i

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