Abstract
A method of producing abrasion resistant cordage from polyester yarn requires treating the yarn after drawing with an aqueous overfinish composition that contains an oxidized polyethylene emulsified with a quaternary amine cationic emulsifying agent and a siloxane compound of the comonomers dimethyl and 3-((2-aminoethyl)aminopropyl) in an effective amount to apply a sufficient level of each of the components to the treated yarn to provide enhanced wet and dry abrasion resistance to the resulting cordage; then forming cordage from the treated yarn.
