摘　　要：介绍了涤粘织物的浸染工艺,包括退浆、染料和固色剂选择等。试验结果表明,涤粘织物采用碱氧法退浆,退浆率较热水法退浆和精练法退浆高,且织物基本无淀粉和PVA浆残留;选择染料时,其直接性系数S及比移值Rf应尽量接近,以保证拼色的同色性和配伍性;可根据固色剂耐皂洗牢度和耐碱性水洗牢度,以合理选取固色剂及工艺条件。Exhaust dyeing process of polyester/viscose fabric was introduced, including desizing process and selections of dyes and fixation agent. There was no residue of starch and PVA on treated polyester/viscose fabric with oxygen-alkali desizing process, and desizing percentage was high compared with hot-water desizing and scouring process. Uniformity and compatibility of mixed dyeing were better when the selected trichromatic reactive dyes having close substantivity coefficient （ S ） and migration value Rf. Fixation agent and process conditions could be chosen according to soaping fastness and alkali-washing fastness.
