説明

The effect of poly (ethylene glycol) (PEG) on the solubilization behaviors of an anionic surfactant, sodium n-dodecylbezene sulfonate (DBS), toward oil-soluble monoazo dyes and the anti-redeposition behaviors of the surfactant toward carbon black soil has been investigated in aqueous DBS-PEG mixed solutions with 0.05 mol/l of sodium sulfate.<BR>The amount of solubilized dye and the solubilizing power (Sp) increased considerably with an increase in the concentration and weight-average molecular weight (Mw) of PEG. The surfactant concentration at the start of solubilization (Cb) varied in an opposite tendency from Sp. These results are interpreted in terms of DBS-PEG complexes formed by binding between DBS and PEG in water.<BR>The detergency efficiency (D) to the carbon black soil for cotton and nylon fabrics increased with increasing the concentration of PEG. The degree of soil-redeposition (S) on these fabrics showed a reverse tendency from D. Further, it was shown that there is a critical molecular weight level at which the antiredeposition properties of PEG are greatest. It is suggested that PEG is effective as an anti-redeposition agent to carbon black soil/cotton or nylon fabric systems.
