Zusammenfassung: | An aqueous size composition for cotton-containing textile yarn comprising in an aqueous solution (a) 100 parts polyvinyl alcohol (b) 2-15 parts hydrophobic waxy material (c) 0.2-5 parts ethylene oxide-propylene oxide surfactant which has a surface tension between about 37 and 48 dynes/cm as a 0.1% aqueous solution at 25 DEG C., and a foaming number less than about 20 (ml foam/g solution) DEG F. as a 7% aqueous polyvinyl alcohol solution containing 11.4 parts hydrogenated tallow wax and 2 parts surfactant per 100 parts polyvinyl alcohol. |
