项目摘要

This research has been done in the period from 1998 to 2000 by 9 investigators between in Kyoto Institute of Technology and in University of Leeds. The aim of the research was to investigate and develop new technologies for diminishing the environmental impacts of dyeing industry.Research group at University of Leeds has mainly investigated the modification of the cellulosic and nylon fabrics with novel chemicals so that the fabrics have more affinity to dyes. From the results of the investigation, the chemically modified fabrics were found to have increased affinity to the conventional dyes and the dye exhaustion in dyeing process became perfect. With these technologies the environmental impacts of the effluent from the dye house would be appreciably diminished.The research group in Kyoto Institute of Technology has investigated the new dyeing process that has less influence to the environment. Dyeing technology with using non-aqueous solvent has been investigated. Dyeing cellulosic substrate as well as other synthetic substrates could be dyed with the conventional dyes with using aliphatic hydrocarbon as a dyeing solvent with the help of the existence of surfactant that formed reverse micelle to accommodate the hydrophilic dyes in the non-polar solvent. The exhaustion of the dye into the fabric substrates was almost perfect and the residual solvent could be recovered by distillation for reuse. The photo-modifications of the fabric substrates have also been investigated in order to improve dye exhaustion when dyeing.The results from these investigations done in both institutions showed that the new technologies could be practically applicable to diminish the environmental impacts of the dyeing industry.

本研究由京都工业大学和利兹大学的9名研究人员于1998年至2000年期间完成。该研究的目的是研究和开发新技术，以减少染色工业对环境的影响。利兹大学的研究小组主要研究了用新型化学品对纤维素和尼龙织物进行改性，使织物对染料具有更大的亲和力。结果表明，改性后的织物对常规染料的亲合力提高，染色上染率提高。通过这些技术，印染厂的废水对环境的影响将明显减少。京都工业大学的研究小组研究了对环境影响较小的新染色工艺。研究了非水溶剂染色工艺。以脂肪族烃为染色溶剂，在表面活性剂存在下形成反胶束，将亲水性染料容纳在非极性溶剂中，可使纤维素类及其它合成材料用常规染料染色。染料几乎完全吸收到织物基材中，残留的溶剂可以通过蒸馏回收用于再利用。研究人员还研究了织物基质的光改性，以改善染色时的染料上染率。这两个机构的研究结果表明，新技术可以实际应用于减少染色工业对环境的影响。
