  • Stainblockers for nylon fibers
    Patent number: 5349038
    Abstract: Oligomeric condensation products including repeat units of the formula: ##STR1## wherein M.sup.+ is a monovalent metal cation; and wherein a=1 or 2 and R is C(R.sub.f).sub.3, or wherein a=O, 1 or 2 and R is ##STR2## wherein each R.sub.f group is independently selected from the group consisting of Fluorine (F) or a perfluoroalkyl group;and b=0, 1 or 2; anda+b=0, 1 or 2; with the proviso thata+b=1 or 2 for at least about half ofsaid repeat units.The products are useful as stainblockers in nylon carpets.

  • Copolymeric yarns for textured carpets
    Patent number: 5209974
    Abstract: Heatset, textured (e.g. stuffer box textured), continuous filament, nylon carpet yarn useful for making textured carpets is disclosed. The yarn is made from nylon 66 copolymer. Textured carpets made from the yarns of the invention have improved aesthetics and/or appearance retention characteristics as compared to textured carpets made from nylon 66 carpet yarns.

  • Nylon spin-texture process
    Patent number: 4457883
    Abstract: In producing nylon yarns having latent crimp by the process disclosed in U.S. Pat. No. 4,202,854, the polymer throughput (i.e. extrusion rate) is increased without sacrificing the amount of uniformity of the bulk resulting from development of the latent crimp by adding a nucleating agent, such as calcium fluoride, to the nylon prior to extrusion.
