ʷ A series of poly[3-methylene-3\\\'-methylenesodiumbisulfite-bis(4-hydroxyphenyl) sulfone] (PMSBPS) was synthesized by the reaction of bis-(4-hydroxyphenyl)sulfone(BPS), formalin, and formaldehyde sodium bisulfite(FSB), and their effect on the staining of direct dye on nylon in the dyeing of nylon/cotton union fabric was investigated. PMSBPSes have good staining resist effect on nylon in the dyeing of nylon/cotton union. Prolonged reacting time between BPS and formalin is effective in improving the staining resist of final PMSBPS. Too many sulfonic acid groups than necessary in the PMSBPS increase the staining of nylon, presumably by increasing the solubility of PMSBPS. Staining resist effect of PMSBPS was evident in the measurement of color diffence of dyed goods.
