    Abstract: An apparatus and method for texture heat-setting bulk continuous filament (BCF) yarns in hot air heat-setting machines that includes a preheating device/step that in the processing of BCF yarns. The apparatus and method use a mixture of steam and atmospheric air to preheat a twisted BCF yarn bundle to develop crimp memory and provide cohesion to the twisted BCF yarn bundle. Yarn bundle cohesion during texture heat-setting helps to avoid frequent breaks at the winder of the hot air heat-setting machine. The addition of the preheating device/step significantly improves the ability of hot air heat-setting machines to maintain continuous operation during texture setting of BCF yarns and makes the hot air heat-setting method commercially viable for this application.

    Abstract: Disclosed are processes for applying dyes, stain blocker and anti-soil compositions on BCF yarns during cable or air twisting processes, or heat setting processes, prior to weaving, knitting or tufting. Further discloses are process for applying dyes, stain blocker and anti-soil compositions on BCF yarns prior to heat setting. The processes forego the need to dye and otherwise treat carpets and other textiles made from the BCF yarn using current methods. Also disclosed are systems, BCF yarns, and carpets made from the BCF yarn treated by the disclosed process.

    Abstract: Disclosed are processes for applying anti-soil compositions on BCF yams during cable or air twisting processes prior to weaving, knitting or tufting. The process foregoes the need for downstream environmentally unfavorable dyeing and low pH chemical treatment processes on the finished carpet. The anti-soil composition can be comprised of a high specific surface energy chemical or other material, for example a fluorochemical. Further, the anti-soil composition can further comprise an anti-stain component. Also disclosed are systems, BCF yarns, and carpets made from the BCF yarn treated by the disclosed process.
