Abstract

Tensile and cycle loading processes of PA6 and PA6.6 pile yarns, designed for carpets, were investigated. Tensile and cycle loading tests were conducted on Statimat M tension device. Elongation at break, tenacity, work of rupture was assessed during tensile tests. Dynamic modulus and dynamic strain (after 10 cycles loading), were assessed during cycle load tests. Cycle loading was performed between two force levels. Results of tensile tests showed that PA6 yarns are stronger than PA6.6 yarns, and can be distinguished because of better dynamic parameters. Therefore it is better to use PA6 yarns for carpets designed for places of intensive load.
