摘　　要：在碱性条件下,以水为溶剂提取苦荞染料。苦荞与水的料液比1:30,pH值8,100℃提取60min,苦荞染料的提取率达38.4%。棉针织物苦养染料优化染色工艺为:染料8%,80。C染色60min,浴比1:20,pH值9。苦荞染料铁盐同浴媒染工艺为FeSO_4 5%,染料8%,80 C染色80 min,浴比1:20,pH值5。染色织物各项色牢度均在3级以上,且具有良好的抑菌效果。The extraction of tartary buckwheat dyes is carried out under alkaline conditions with water as the solvent. When the solid-liquid ratio of buckwheat to water is 1 ： 30, extraction at 100 ℃ for 60 min at pH value 8, the extraction rate of buckwheat dye reaches 38.4%. The optimal dyeing process of cotton knit fabric is： buckwheat dyes 8%, dyeing at 80 ℃ for 60 min, bath ratio 1：20, pH value 9. Metachrome buckwheat dyeing process with ferric salt is FeSO4 5%, dyes 8%, dyeing at 80 ℃ for 80 min, bath ratio 1：20, pH value 5. The dyed fabric has color fastness of above Grade 3, and good antibacterial effect.
