摘要
采用天然植物染料黄连染腈纶纤维,在中性浴条件下提取黄连染液,对黄连提取液的稳定性进行测试,并用提取液对腈纶染色,通过直接染色单因素实验、媒染染色及其平行实验测定染色K/S值和色差,选取最佳工艺条件。实验结果表明:染色温度和染料浓度对染色效果的影响较大,后媒染色要比预媒染色效果好。通过铁盐预媒染色的正交试验得出最佳工艺:铁盐0.01 mol/L,时间40 min,温度70℃,浴比1∶40。实验结果表明黄连提取液染腈纶纤维水浸牢度较好。
In this paper, rhizome coptidis was researched as a natural plant dye in the dyeing on acrylic fiber. Extracting the dye liquor from rhizome coptidis under the natural baths condition, dyeing the acrylic fibers with the extract, and the stability of the extract was tested. The dyeing K/S value and color difference were determined by direct dyeing single factor experiment, mordant dyeing and parallel experiment, and the best process conditions was decided. The results of the experiments showed that the dyeing temperature and dye concentration had great influnce on dyeing effect, and the post-mordant dyeing was better than the pre-mordant dyeing. The optimal process was obtained by the orthogonal experiment of ferric salt pre-mordant dyeing： ferric salt 0.01 mol/L, time 40 min, temperature 70 ~C , bath ratio 1：40. The results of the experiments show that rhizome coptidis extract dye acrylic fiber fastness to better.
