摘要
为提升核桃木质壳的利用价值以及拓展天然染料来源,探究了核桃木质壳色素提取工艺并考察了其对棉织物的染色性能。结果表明:NaOH浓度为1.0 g/L,料液比为1∶20,提取温度为100℃,时间为60 min时,所得提取液对棉织物染色性能最佳;棉织物预处理阳离子改性剂为1.0 g/L,在80℃染色60min时,染色织物K/S值可达1.75;采用同媒染色法,FeSO_(4)用量为2%,提取液用量为30%时,染色织物K/S值为1.34,提高了色素利用率;所得染色棉织物色牢度达到了纺织品服用标准要求。
In order to improve the utilization value of walnut shell and expand the source of natural dyestuff,the dyestuff extraction technology of walnut shell was studied and its dyeing properties on cotton fabric were investigated. The results showed that when the concentration of NaOH was 1.0 g/L, the ratio of material to liquid was 1∶20, the extraction temperature was 100 ℃ and the time was 60 min, and the dyeing performance of cotton fabric was the best. And when the pretreatment cationic modifier of cotton fabric was 1.0 g/L, the temperature is 80 ℃and the keeping time is 60 min, the dyeing value of K/S reaches 1.75. When the amount of FeSO_(4)was 2% omf and the dosage of extraction solution was 30%, the dyed fabric K/S was 1.34, which improved the dyestuff utilization rate. The dyeing fastness of the dyed cotton fabrics met the requirements of textile standards.
