ABSTRACT

Recently, natural dyes are used because these are environment-friendly, less lethal, and do not have any detrimental effect on health. For the present study, the cotton fabric and the mixed powder (pomegranate rind and turmeric rhizome) have been irradiated for (1–5) min. It has been found that 3 min is the effective exposure time for improvement in dyeing behavior of cellulosic fabric. Good color strength was observed by dyeing fabric irradiated at 65°C for 40 min in dyeing bath having pH 6. For improvements in color fastness, the optimum concentration of pre-mordant (4% copper) and post-mordant (8% chrome) was employed. It is observed that microwaves increased the color strength as well as color fastness properties of irradiated cotton using aqueous solubilized mixed extract of irradiated pomegranate rind and turmeric rhizome powder.

摘要

最近使用天然染料是因为它们对环境友好，杀伤力较低，对健康没有任何有害影响. 在本研究中，棉织物和混合粉末（石榴皮和姜黄根茎）被辐照1-5分钟. 结果表明，3min是改善纤维素织物染色性能的有效曝光时间. 在pH值为6的染液中，将辐照后的织物在65℃下染色40min，可获得较好的染色强度. 为了提高染色牢度，采用了前媒染剂（4%铜）和后媒染剂（8%铬）的最佳浓度. 微波辐照石榴皮和姜黄粉的水溶性混合提取物提高了辐照棉的色强度和色牢度.
