DU Juan, ZHAN Li , CHEN Shui-lin (College of Chemistry and Chemical Engineering, Donghua University, Shanghai, 200051)
The process parameter of silica sol formation was investigated by evaluating its fixing effect on cotton dyed direct dye with poor fastness. It was found that lower temperature, acid catalyze, appropriate concentration and time were indispensable to silica sol as a fixing agent.
