Process for sizing filament yarn utilizing an improved warp size composition of PVal, urea and saccharide

摘要

An improved warp size for filament yarn is provided consisting essentially of polyvinyl alcohol, urea, and mono- and di-saccharides, such as sucrose, which when applied to filament yarn from aqueous solution provides excellent abrasion resistance, low shedding, freedom from skinning, and outstanding ease of removal.
