摘　　要：为了探寻天然植物染色中红色系染材茜草和苏木对亚麻棉混纺织物染色的呈现效果,采用水煎法萃取茜草和苏木染液,在不同媒染剂种类和不同媒染工艺下,进行单染和混染实验.对比不同媒染方式下所得织物染色的K/S值与L^(*)、a^(*)、b^(*)、c^(*)等颜色特征值,并进行色牢度测定.结果表明:亚麻棉混纺织物在茜草单染上颜色较浅,普遍呈暗粉调,在明矾同浴媒染下颜色纯度最高;苏木单染颜色较深,呈暗红调和紫调,在明矾预媒染下颜色纯度最高;茜草和苏木混染颜色介于前两者之间,在明矾同浴媒染下颜色纯度最高;媒染之后,织物耐皂洗色牢度及耐摩擦色牢度均达到3~4级以上,符合纺织染色出口标准.In order to explore the dyeing effect of red dyeing materials madder and hematoma on linseed cotton blended fabric in natural plant dyeing,the dyeing solution of madder and hematoma are extracted by water decocting method,and single factor single dyeing and mixed dyeing experiments are carried out under different mordant types and different dyeing technologies.The color characteristic values such as K/S value,L^(*),a^(*),b^(*),c^(*)value are compared under different dyeing methods,and the color fastness is measured.The results show that the color of linen-cotton blended fabric is lighter in alizarin single dyeing and generally dark powder,and the color purity is the highest in alum in the same bath medium.The color of hematoxylum single dyeing is dark and purplish red,and the color purity is the highest under alum pre-dyeing.The color of alizarin and hematoxylum mixed dyeing is between the former two,and the color purity is the highest under alum dyeing with bath medium.After medium dyeing,the color fastness to washing and rubbing of the fabric reaches grade 3-4 or above,which meets the textile dyeing export standard.
