Resilience behaviors of woven acrylic carpets under short- and long-term static loading

Appearance stability of woven carpets has been a great problem in the carpet industry for years. In this research, analysis of the various components of the woven carpet structure was performed to identify the role each component plays in the phenomenon of thickness loss recovery. Short- and long-term static loadings were used to test various samples of pile height (9, 10, 12.5, and 14 mm) and pile density (1600 and 2400 piles/dm2). We found that acrylic-carpet structural parameters of pile height and pile density significantly affected the thickness-loss recovery. In short-term loading, the carpet samples exhibited remarkable recovery of thickness loss in the first 15 minutes. Acrylic carpets reached 80% to 93% and 74% to 89% of their initial thickness in 1 hour after the short-term loading and 24 hours after the long-term loading, respectively.
