Influence of Pile Height and Density on the End-Use Properties of Carpets

Abstract

Nine different face-to-face cut pile carpets were used for the investigation. The raw material of the carpet pile yarns was wool and polyamide blended yarns. The influence of the different structure parameters (carpet pile density and pile height) on the carpet properties was investigated. The deformations occurring in carpets during compression were determined. A compressive load of 100 N was applied to the surface of the carpets, and three cycles of loading were performed. An orthogonal mathematical plan was used to investigate resulting deformations. As regards the total deformation, results showed that both of the structure parameters of the carpets have an influence – in elastic deformation pile density is the parameter which has the biggest influence, and in unrecovered deformation both of the structure parameters have a great influence.
