Effect of pile fiber cross section shape on compression properties of polypropylene carpets

摘要

Fiber cross section shapes, which have a direct influence on the physical properties of textile surfaces, are becoming more and more complex recently. There are also many important properties of the carpets such as luster, resilience, abrasion resistance which are impacted by the shape of the fiber cross sections. In this present paper, the influence of pile fiber cross section shape on compression properties of carpets was experimentally investigated under short and long-term static loadings. The material used was polypropylene carpets having two different pile fiber shapes: trilobal and hollow. The experimental results indicate that percentage thickness loss of carpets having hollow piles is slightly higher than carpets with trilobal piles in both short- and long-term static loadings. However, in the case of percentage recovery, similar values were obtained for the samples used in this study.
