ABSTRACT
In this work, organic cotton fabrics were dyed using Rhamnus petiolaris Boiss, Quercus ithaburansis Decaisne, and Quercus ithaburansis Decaisne + Rhamnus petiolaris Boiss by microwave irradiation and conventional dyeing methods. They were used in equal percentages. The dyed fabrics were analyzed by different analytical and technical methods. Coloring compounds were analyzed in the dye extractions (before dyeing bath and after dyeing bath) and dyed fabrics by RP-HPLC-PAD. Identified coloring compounds based on the coloring compounds analysis were kaempferol, kaempferol derivative, quercetin, rhamnetin, ellagic acid, ellagic acid derivatives, and gallic acid derivative. Color characteristics of all the dyed fabrics were measured by CIEL*a*b* spectrophotometer. SEM-EDX was used for imaging of the dyed organic cotton fabrics. The coloristic and color fastness properties of the dyed fabrics were investigated and compared with each other. No damage was observed in the fabrics dyed by the microwave and conventional dyeing methods. Almost the same color yields were obtained in both dyeings using different processing times. According to the analyzes and test results, microwave irradiation method is very eligible compared to conventional dyeing methods, considering coloristic properties of dyed fabrics, time saving and the cost effectiveness wise for the dye processes.
摘要
采用微波辐射和常规染色方法，对有机棉织物进行了鼠李、十芒栎和十芒栎+鼠李的染色研究.
它们被同等比例地使用. 采用不同的分析方法和工艺方法对染色织物进行分析. 采用RP-HPLC-PAD法对染色液（染色浴前和染色浴后）和染色织物中的着色化合物进行了分析. 根据显色化合物的分析鉴定出的显色化合物有山奈酚、甘珀酚衍生物、槲皮素、鼠李素、鞣花酸、艾伦酸衍生物和没食子酸衍生物. 用CIEL*a*b*分光光度计测定了所有染色织物的颜色特性. 采用扫描电镜-能谱仪对染色后的有机棉织物进行了图像分析。对染色织物的色牢度和色牢度进行了研究和比较. 微波染色和常规染色对织物无损伤. 两种染料在不同的处理时间得到几乎相同的显色率. 根据分析和测试结果，考虑到染色织物的显色性、染色工艺的省时性和成本效益，微波辐射染色法与传统染色法相比具有很大的优越性.
