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.

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.

Abstract: The present invention relates to a method of and a device for optimizing at least one coating material at at least one point of a substrate surface to which the coating material is applied.
