An Investigation on Some Mechanical Properties of the Tuft Carpets Produced by Homopolymer, Copolymer and Thermoplastic Polyolefin Mixed Polypropylene Bulked Continuous Filament Yarns

There are several parameters that affect the mechanical properties of carpets such as yarn characteristic and carpet construction. Yarn material is one of the most important factors which determine the usage performance of carpets by consumers. This study investigated the mechanical behaviours of carpets produced from polypropylene (PP) bulked continuous filament (BCF) yarns with not only polypropylene homopolymer but also mixing with copolymer (coPP) or thermoplastic polyolefins (TPO). In this respect, nine carpet samples produced by different types of BCF yams used as pile were examined. Experimental results indicated that mixing polypropylene homopolymer with copolymer or thermoplastic polyolefin resulted with improvement in thickness loss and resilience properties. In addition, thermoplastic polyolefin mixed samples exhibited higher performance compared to those of copolymer, in both dynamic and static loading. PP BCF yarn composition had considerable influences on compressibility behaviours of carpets, whereas there was no significant effect on tuft withdrawal force.
