Detergency effects of poly (sodium α-hydroxyacrylate); PHA on artificially soiled cotton fabrics without surfactant were investigated at various values of water hardness and molecular weight of the polymer and compared those of sodium dodecyl sulfate; SDS and other similar-structured polymers, such as poly (sodium acrylate); PA and poly (vinyl alcohol); PVA.
The detergency of PHA was found not to depend on water hardness and was much higher than that of SDS for any value of high hardness. Detergency increased with molecular weight and remained constant above 10500. PHA showed higher detergency than PA or PVA.
