涤纶纤维表面化学镀镍–磷工艺研究

Study of electroless nickel–phosphorus plating process on polyester fiber surface

以涤纶纤维的增重率和电阻为指标，研究了镀液组成、pH、温度、涤纶装载量和施镀时间等对化学镀镍-磷的影响，得到涤纶化学镀镍-磷的最佳工艺条件为：柠檬酸钠10 g/L，硫酸镍20 g/L，次磷酸钠8 g/L，乙酸钠15 g/L，镀液pH为6.0-6.2，温度80℃，装载量9 g/L，时间10-15 min。采用最佳工艺对涤纶纤维化学镀镍-磷后其增重率约为19%，电阻约为10Ω/cm。

The effects of plating bath composition, pH, loading capacity of polyester, and plating time on electroless nickel–phosphorous plating were studied by evaluating the weight gain rate and resistance of polyester fiber. The optimal process parameters of electroless nickel–phosphorous plating were obtained as follows： sodium citrate 10 g/L, nickel sulfate 20 g/L, sodium hypophosphite 8 g/L, sodium acetate 15 g/L, pH 6.0-6.2, temperature 80 ℃, loading capacity 9 g/L, and time 10-15 min. The polyester fiber obtained after electroless nickel–phosphorous plating under optimal process conditions has a weight gain rate of ca.19%and a resistance of 10Ω/cm.
