Study on thickness loss of cut-pile carpet produced with heat process modified polyester pile yarn. Part II: dynamic loading

Thickness loss (TL) is one of the most important mechanical properties in each carpet. In this research, four types of ATY polyester pile yarns were used to prepare the cut-pile carpet samples. They were normal ATY polyester filament pile yarns and three yarns that modified by heat processes including friezing, heat setting, and twist heat setting. Woven carpet samples are subjected to standard dynamic loading test. Results show that friezing and heat setting processes have no significant effects on carpet dynamic recovery or TL after dynamic loading. Also, decreasing temperature of twist heat setting, the polyester pile yarns could not modify carpet TL after dynamic loading.
