摘　　要：在已镀铜的涤纶织物上电镀锡镍合金，得到了一种表面致密均匀的柔性电磁屏蔽材料，对制备工艺进行了初步研究与探讨。试验表明，焦磷酸钾150g／L，氯化铵5—10g／L，甘氨酸10g/L，温度25～30℃，电流密度0．67-1A·dm^-2时，得到的功能性纺织品色调高雅，光泽柔和，且具有良好的电磁屏蔽性能。锡镍合金镀层元致敏性，从而减少传统的镍镀层材料对人体的危害；减少镍的用量，降低了生产成本，具有明显的现实意义与广阔的应用前景。A soft electromagnetic shielding material of Cu - plated PET fabric which is re-plated with tin - nickel alloy were prepared. Test shows that when plated with 150 g/L potassium pyrophosphate, 5 - 10 g/L ammonium chloride, and 10 g/L glycine, at temperature of 25 - 30℃, with current densitiy in a range of 0.67 - 1 A/dm^2 , the function textiles with elegant color, glossy soft, and good electromagnetic shielding property could be made. Tin - nickel alloy coats reduces harm of traditional nickel materials on human body and the cost of production, so it has obvious practical significance and broad prospects.
