Abstract (en)
As the processes of friction texturing of POY PES are insufficiently investigated, in the context of this dissertation the influence of texturing process parameters on the properties of textured PES filaments was studied under real-plant conditions, on the equipment with a short heating zone. As experimental material POY PES filament yarn was used that was textured under industrial conditions by changing heater temperature, texturing speed, D/Y ratio in texturing zone and the stretching degree. The samples of textured yarns obtained were characterized regarding the new structure obtained (crystallinity degree, degree of orientation) and properties (fineness of textured yarns, breaking strength and breaking elongation, and also yarn elasticity characteristics and yarn shrinking).
The results obtained enabled determination of physical-chemical changes on yarns textured with various texturing parameters and also their impact on physical-mechanical properties of textured yarns.
