ABSTRACT:
A process for lubricating acrylic fibers before dyeing in which packages of acrylic yarn formed by winding acrylic yarn about a dye tube are treated immersed in an aqueous lubricating bath containing a polyethylene, a low melting paraffin wax emulsion; and a high melting paraffin wax emulsion, followed by raising the temperature of the bath, to sequentially coat the fibers of the yarn with the polyethylene, the low melting paraffin wax emulsion, and the high melting paraffin wax emulsion. The yarn packages are then separated from the lubricating bath, and immersed in a dye bath to dye the yarn. In commercial application, the lubrication and subsequent dyeing is conducted in the chamber of a dye machine.
