摘　　要：对涤棉织物分散/活性同浆印花用染料和工艺条件进行研究。通过筛选染料,研究烘干温度、焙烘固色时间和温度,印花色浆中尿素、碱的用量对分散、活性染料固色率的影响,确定最佳焙烘工艺条件,同时研究了表面活性剂对印花沾色性能的影响。结果表明:使用合适的染料和热焙烘工艺,活性染料和分散染料都能得到很好的固色效果,印花产品的各项牢度优良,平平加O和防沾色剂的混合碱水洗涤可以很好地防止白地沾污,工艺能满足生产需要。This paper investigated the printing of polyester/cotton fabrics by one paste of disperse and reactive dyes in respect of dye selection, the impact of drying temperature, curing time and temperature, urea and alkali consumption on the fixation rate of the reactive dye, as well as the effect of surfactant on anti-staining. The optimum technology was determined. The experimental results revealed that employing proper dyes and curing process can render the printed fabric with good color fastness and fixation rate of both disperse and reactive dyes. Washing with mixed alkali water containing Peregal O and anti-staining agent can very well prevent staining to white ground. This process can meet the requirements of practical production.
