中文摘要：为深入了解各类织物对茶多酚中各儿茶素的吸附情况,采用高效液相色谱分析法,分别测定了蚕丝、棉和锦纶织物对茶多酚中6种不同儿茶素的吸附率,并用硫酸亚铁、硫酸铜和明矾3种媒染剂进行媒染。结果表明,蚕丝、棉、锦纶3种不同织物对茶多酚的吸附能力有较大差异。锦纶与蚕丝织物对酯类儿茶素显示较高的吸附率,而棉织物对非酯类儿茶素显示较高的吸附率。对于同一织物而言,在相同的染色工艺条件下,3种不同媒染剂的媒染效果有较大不同,用亚铁盐媒染能获得较深的颜色,而用铜盐媒染得色较浅,用明矾最浅。对于不同织物,其色泽深浅顺序因不同媒染盐而异,蚕丝织物得色相对较深。

外文摘要：In order to get an insight into the adsorption of chtechins on various kinds of fabrics, the adsorption percentage of six types of catechins on silk, cotton and polyamide fabric were measured respectively by using high-performance liquid chromatography, and the mordanting was carried out with ferrous sulfate, copper sulfate and potassium aluminum sulfate as mordant agents. The results indicated that there was a greater difference in adsorption capacity of tea polyphenols onto silk, cotton, and polyamide fabric. The polyamide and silk showed higher adsorption for catechins of esters, while the cotton fabric adsorb preferentially non-ester catechins. For each of the three fabrics, the effect of three mordant agents was quite different from one another under the same dyeing process conditions, the ferrous salt showed the deepest color, followed by copper salt, and the alum occupied the end position. For different fabrics, the order of color depth varied with the mordant agents, and the silk yielded deeper color relatively.
