20130231454 | BIOBASED FIBRE AND YARN - 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. | 09-05-2013 |
20110257345 | METHOD OF SEPARATING AND CLEANING OF POST CONSUMER CARPET FACE YARN FROM CARPET BACKING AND YARN PRODUCT PRODUCED THEREFROM - A process for producing a synthetic fiber composition with reclaimed post consumer carpet yarn, wherein face yarn is shaved from post consumer carpet using a shaving device to provide shaved face yarn, the shaved face yarn is reduced in size, contaminants are removed using mechanical screeners, the shaved face yarn is melt filtered, and spun into fiber. | 10-20-2011 |
