Abstract: Feedstocks are provided for use in the additive manufacturing of three-dimensional objects via extrusion-based techniques, such as Fused Filament Fabrication (“FFF”) or Fused Deposition Modeling (“FDM”). Generally, the feedstocks may be in the form of substantially continuous filaments and/or in the form of rods of specified length, with diameters in excess of 3.5 mm.

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.

Abstract: 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.

Abstract: Blending of thermoplastic polyester with fiber-forming polyamide in the production of melt-colored melt-spun fibers results in improved color strength and aesthetics, and dimensional stability.

Abstract: Disclosed herein is a hydrophobic sorbent, particularly useful for the sorption of oil or other similar tacky or viscous hydrocarbons, which is prepared by subjecting a water-containing, fibrous cellulosic product, particularly sulphite reject fibers, to rapid heating to cause expansion of the fibers through gasification of the water therein. The sorbent is capable of exceptionally rapid and tight sorption and binding of even heavy oils.
