ABSTRACT
Based on conventional pad-dry-pad-steam (PDPS) process, 3-chloro-2-hydroxypropyltrimethylammonium chloride was used as an etherifying agent to cationize cotton by the pad-irradiate process by microwave and then the cationized fabric was salt-free dyed by the pad-steam process. The results showed that the dyeability of the cationized fabric with salt-free reactive dye was nearly equivalent with conventional PDPS process. This study also developed a model to predict K/S value of dyed cotton fabric based on least squares support vector machine (LS-SVM). The simulation results based on actual run data demonstrated that the model using LS-SVM has high prediction accuracy and can be employed to predict the K/S value of dyed fabric using pad-irradiate-pad-steam process.
摘要
在传统的轧-烘-轧-蒸(PDPS)工艺基础上,以3-氯-2-羟丙基三甲基氯化铵为醚化剂,采用轧-微波辐照工艺对棉进行阳离子化,然后采用轧-蒸工艺对阳离子化织物进行无盐染色。结果表明,阳离子化织物无盐活性染料染色的染色效果与传统PDPS工艺基本相当。基于最小二乘支持向量机(LS-SVM),本研究建立了染色棉织物K/S值的预测模型。基于实际染色数据与预测结果表明,利用LS-SVM建立的模型具有较高的预测精度,可用于预测轧-微波辐照-轧-蒸工艺染得织物的K/S值。
