Abstract
An improved warp size for filament yarn is provided consisting essentially of polyvinyl alcohol, alkyl phenoxy (or cresoxy) ethoxyethyl dimethylbenzyl ammonium chloride and a plasticizer such as glycerol or urea, which when applied to filament yarn from aqueous solution provides excellent weaving efficiency and ease of removal combined with low shedding in the loom.
