摘　　要：考察不同pH值对涤纶涂布所用Ag用量在0.0～2.0 mg/cm^2（0.0-263 mg[Ag（NH3）2]^＋离子）和10.0 mL C6H12O6还原剂在0.0～10.0 g/L条件下的最佳条件，反应后涤纶按GB/T 3920—2008和GB/T 251—2008测定镀层干摩擦色牢度.试验结果表明，试验镀层稳定性与pH关系密切.pH=10～12时，可有效提高[Ag（NH3）2]^＋离子利用率，Ag优化用量为1.5 mg/m^2， C6H12O6还原剂化学镀Ag优化浓度为8.0 g/L，有利于优化涤纶化学镀Ag层处理成本，同时有助于防止对操作技术人员的伤害和实现环境友好化.The processes of activation / reduction by [Ag（NH3）2]^＋ / C6H12O6 with different values of pH are carried out to optimize the amount of Ag and concentration of glucose.The pH values are to change the effective concentration of [Ag（NH3）2]^＋,which decrease the effective concentration of [Ag（NH3）2]^＋ under pH=10-12. pH=12-14 are to maintain the high effective concentrations of [Ag（NH3）2]^＋ in solutions for activation / reduction. It is concluded that the optimal condition in this test is Ag amount of 1.5 mg/m2 and glucose concentration of 8.0 g/L to reduce the cost of electro-less silver coating and effect the environment-friendly treatment.
