Abstract
A spin finish composition for polyamide yarn to be processed into plied, bulked, continuous filament carpet yarn, comprising coconut oil, polyoxyethylene hydrogenated castor oil and the potassium salt of polyoxyethylene tridecyl alcohol phosphate. This finish improves processing of the yarn at high temperature, as by steam jet texturing, and prevents excessive tension build-up during subsequent cabling operations.
