Abstract: There is disclosed herein various floor coverings and methods for making the same. In one embodiment, there is disclosed a floor covering including a primary backing layer having a fibrous face and an underside, wherein the fibrous face is formed from a bulked continuous filament yam comprising a plurality of continuous filaments formed from a biobased polyhexamethylene sebacamide polymer or a blend of a biobased polyhexamethylene sebacamide polymer together with up to 80 wt % of at least one other polymer compatible with the biobased polyhexamethylene sebacamide polymer.
Abstract: There is disclosed herein a multicomponent fibrous assembly comprising a plurality of continuous filaments formed from a biobased polyhexamethylene sebacamide polymer or a blend of a biobased polyhexamethylene sebacamide polymer together with up to 80 wt % of at least one other polymer compatible with the biobased polyhexamethylene sebacamide polymer. There is also disclosed a process for preparing a biobased polyhexamethylene sebacamide bulked continuous filament (BCF) yarn comprising melt-spinning a polymer melt containing polyhexamethylene sebacamide polymer or a blend of a biobased polyhexamethylene sebacamide polymer together with up to 80 wt % of at least one other polymer compatible with the biobased polyhexamethylene sebacamide polymer to form at least one filament, passing the at least one filament to a drawing stage where the filament is drawn and lengthened to produce a yarn, followed by texturing the yarn.
