  • Patent number: 6448370
    Abstract: The end group content of polyamide in the solid state may be reduced by treating the polyamide with gas-phase acid, anhydride, or amine. Stain- or dye-resistant polyamide fibers can be made by reducing the number of amino end groups. Reduction in the number of carboxylic end groups reduces the rate of regeneration of starting monomers during extrusion.

  • Patent number: 6447703
    Abstract: Processes and apparatus are provided whereby the morphology of bulked continuous filament (BCF) yarns can be variably controlled. More specifically, according to the present invention, the BCF yarn is melt-spun, drawn and textured, most preferably in a one-step spin-draw-texture (SDT) process, wherein prior to texturing, the yarn is subjected to a differential temperature condition. Most preferably, such differential temperature condition is accomplished using the duo rolls employed in drawing the BCF, such that one of the rolls is maintained at a greater temperature as compared to the other of the rolls. Most preferably, it is the upstream-most roll (relative to the general conveyance path of the filament toward the texturizer) which is the hotter of the duo rolls.

  • Patent number: 6448300
    Abstract: The invention relates to expandable olefin bead polymers which comprise a blowing agent with a boiling point of from −5 to 150° C., selected from the group consisting of alkanes, alkanols, ketones, ethers and esters. The particles are unfoamed and have a bulk density above 500 g/l, and can be foamed to a bulk density below 200 g/l after storage for one hour at room temperature in free contact with the atmosphere. They are prepared by impregnating polyolefin pellets in suspension in a pressure vessel with the blowing agent, cooling the batch below 100° C., reducing the pressure and isolating the particles.
