Abstract (en)
[origin: EP0252477A2] An aqueous waxless size composition for textile yarn comprising in an aqueous solution (a) 100 parts polyvinyl alcohol and (b) 2-6 parts ethylene oxide-propylene oxide surfactant which has a surface tension less than 49 dynes/cm, preferably between about 40 to 48 dynes/cm, as a 0.1% aqueous solution at 25 DEG C, and desirably a foaming number less than about 20 (ml foam/g solution) DEG F as a 7% aqueous polyvinyl alcohol solution containing 4 parts surfactant per 100 parts polyvinyl alcohol.
