Effect of pile yarn properties and abrasion factor on thermal and sound absorption performance of carpets

Abstract

The study aims to examine the impact of long-term use on the thermal conductivity and sound absorption properties of carpets, with the broader goal of identifying pile-yarn production parameters that can be used to extend carpet lifespan and support sustainability. In this study, Wilton-type face-to-face carpets are produced using pile yarns with different filament fineness values and texturing parameters. The carpets are then subjected to an abrasion test, and their acoustic and thermal performances in both abraded and non-abraded states are evaluated. The results indicate that pile yarns produced with a filament fineness of 3.13 dpf, a ceramic disc type, and a 1-7-1 disc combination exhibit greater resistance to declines in thermal conductivity and sound absorption during prolonged use. These parameters are therefore suggested as preferable for enhancing carpet longevity and reducing environmental impact.
