摘　　要：为了提升红花黄色素对羊毛的染色性能,研究了杨梅栲胶在不同工艺条件下对红花黄色素染色羊毛织物的K/S值、颜色特征值以及色牢度的影响,并采用能谱仪(EDS)分析染色织物上媒染剂的含量,分析提高色牢度的原因。在红花黄色素与杨梅栲胶同浴染色,然后再采用硫酸铝后媒染的最佳工艺基础上得到:红花黄色素与4%(owf)杨梅栲胶在pH值为4、染色温度95℃条件下同浴染色45 min,然后在60℃条件下,用6%(owf)硫酸铝媒染,能显著提升羊毛染色织物的耐光色牢度,使染色织物的各项色牢度均达到4级及以上;EDS测试表明,加入杨梅栲胶后有更多的铝离子参与了配位键的形成。In order to improve the dyeing performance of safflower yellow on wool,the effects of Box myrtle extract on the K/S value,color characteristic value and color fastness of safflower yellow dyed wool fabric under different process conditions were tested,and the content of mordant on dyed fabric was analyzed by Energy Dispersive Spectrometer(EDS)to analyze the reasons for improving fastness.On the basis of the optimal process of dyeing safflower yellow pigment and bayberry tannin extract in the same bath,and then using aluminum sulfate for mordant dyeing.The results show that under the dyeing condition of pH 4,95℃and 45 min,safflower yellow and 4%(owf)Box myrtle extract were dyed in the same bath,and then 6%(owf)aluminum sulfate mordant at 60℃could significantly improve the light fastness of wool-dyed fabric,so that the color fastness of dyed fabric reached grade 4 and above.The EDS test shows that more aluminum ions were involved in the formation of coordination bonds after the addition of Box myrtle extract.
