Abstract
A hot-melt warp yarn size composition and a method for applying, desizing, and disposing of it which essentially eliminates atmospheric and water pollution at all stages of the process. The size is a melt blend of ethylene/vinyl acetate copolymer with microcrystalline, paraffin, or hydrogenated tallow wax. It is applied as a melt to warp yarn, desized with hot petroleum solvent, and the extracted size and unrecovered solvent burned to non-polluting carbon dioxide and water.
