ABSTRACT:
Aqueous overfinish compositions, yarns treated therewith, and methods of producing wet abrasion resistant cordage from the yarn are all disclosed. One of the compositions includes an oxidized polyethylene emulsified with a nonnitrogen, nonionic emulsifier and neutralized with an alkali hydroxide, and a compound selected from the group consisting of a siloxane of the comonomers dimethyl and 3-[(2-aminoethyl)aminopropyl], and an amide melamine wax. An alternate finish composition comprises an oxidized polyethylene, neutralized with ammonium hydroxide and emulsified with a non-nitrogen, nonionic emulsifier. Yarn treated with this alternate finish has enhanced wet abrasion resistance. Yarns of this invention are ideally suited for heavy ropes and other industrial cordage applications where wet and dry abrasion resistance and strength are desirable.
