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

Abstract

Carpet as a home textile is usually subjected to static loading. Therefore, compression behavior or thickness loss after a long-term loading is important from point of view of carpet appearance as well as its lifetime. In this study, four types of cut-pile carpet were woven based on face-to-face weaving system. Pile yarns were air-jet textured polyester filament yarns that were modified by different heat processes. Then, the carpets’ compression behavior was investigated by static loading test. Results show that by increasing the temperature in setting of pile yarns twist at the autoclave process, the carpet static recovery increases. However, the friezing and heat-setting processes of pile yarns have no significant effect on the carpet static recovery.
