ABSTRACT:
A finish composition for polyamide yarn which comprises an oil in water emulsion and an effective amount of 2[(hydroxymethyl)amino]ethanol biocide resists bacteria growth and causes the treated yarn to resist yellowing under steam heat treatment. The oil in water emulsion and biocide most preferably form, respectively, 99.9 percent and 0.1 percent by weight of the finish composition. The preferred oil in water emulsion is about 10 to 20 percent by weight of the oil portion, the oil portion consisting essentially of from about 55 to 65 percent by weight of coconut oil, about 20 to 35 percent by weight of polyoxyethylene hydrogenated castor oil, and about 7 to 15 percent by weight of potassium salt of polyoxyethylene tridecyl phosphate. The finish composition is especially useful for application to polyamide yarn to be processed into either staple carpet yarn or bulked continuous filament carpet yarn.
