Abstract (en)

[origin: WO2012125777A2] Disclosed are processes for applying anti-soil compositions onto BCF yarns during cable or air twisting processes prior to weaving, knitting or tufting into finished carpet. 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.
