The silicone with aminoethyl and aminopropyl reacted with sodium chloroacetate in this paper and formed a new structure.Silver ion was added to the modified silicone emulsified latex to form a kind of antibacterial fabric softener.The solvents,reaction temperature and reaction time were studied in this paper.The solvent chose ethanol,catalyst chose tetramethylammonium hydroxide and dosage was 1% of silicone raw material,sodium chloroacetate was 1.6% of silicone,reaction temperature was 80 ℃ and reaction time was eight to ten hours.The emulsifier,which was composed of fatty alcohol-polyoxyethylene ether and isomerism-alcohol-polyoxyethylene ether,was selected according to hydrophile and lipophilic balance(HLB) value.The results indicate that the fabric finished with the latex has a full,soft hand feel and excellent antimicrobial activity.
