ʷ Bola-form electrolytes were synthesized by the reaction of pyridine with 1, 4-dibromobutane or 1, 10-dibromodecane, respectively. The effects of these electrolytes were studied in the dyeing of wool fabric with Orange II. The depth of shade of wool fabric with pretreated electrolyte were independent to the dyeing temperature and higher than those of one untreated. In the case of pretreating the electrolytes, there are no differences in the effects in dyeing behaviors between the 1, 4-dipyridiniumbutane and 1, 10-dipyridiniumdecane. But when the wool fabrics were dyed in water containing these electrolytes, dyeing behaviors were different to the numbers of carbon atom in electrolytes. 1, 4-dipyridiniumbutane has positive effects on the dyeing.
