摘　　要：详细阐述镍网印花中重金属镍产生的原因,提出镍残留量超标的解决办法。研究镍网规格、印花方式、涂料种类、色浆配方和水洗工艺对镍残留量的影响,确定降低镍残留量的优化印花生产工艺。采用开口率更高的Nova网及颗粒度300~400的白涂料EE,同时色浆中加入20.0%的A邦浆和0.5%的螯合分散剂能提升色浆的柔顺度,降低涂料和镍网间的摩擦力。印花水洗则采用7 L/kg的溢流水量,并使用4 g/L螯合分散剂,以增强对金属镍的洗除效果。在此工艺条件下,面料表面的镍残留量可降至1×10^(-6)以内。The causes of heavy metal nickel in nickel screen printing were elaborated on,and the solution for excessive nickel content was proposed.The effects of nickel mesh specifications,printing methods,paint types,color paste formulations and washing processes on the mass concentration of nickel were studied,and the optimized printing production process to reduce the nickel content was determined.Nova mesh with high⁃er opening rate and white coating EE with particle size of 300~400 were adopted.At the same time,20.0%A bond slurry and 0.5%chelating dispersant were added to the color paste to improve the flexibility of the color paste and reduce the friction between the coating and nickel mesh.The printing washing adopted 7 L/kg over⁃flow water and 4 g/L chelating dispersant to strengthen the washing effect of nickel metal.Under this process conditions,the nickel residue on the surface of the fabric could be reduced to less than 1×10^(-6).
