超临界二氧化碳流体染色具有不用水、不向环境排放任何废水等优点。本工作首次成功设计和建造了超临界二氧化碳流体织物绳染色的新型中试装置，实现了纺织品的清洁生产。介绍了中试装置所采用的子系统和主要设备，以及无水绳索染色的应用程序和工艺。此外，还进行了初步实验，以确认在所设计的装置中用超临界二氧化碳流体进行织物绳染色的可能性。绳状染色结果表明，在使用超临界二氧化碳流体的中试规模工厂中获得了令人满意且商业上可接受的产品，具有良好的颜色均匀性、湿洗牢度和摩擦牢度等级为4至5级。此外，通过在染色步骤后采用漂洗程序，观察到更深色调的色牢度提高了一半或一级。与传统染色工艺相比，织物绳状染色的设备和应用工艺更加环保，更清洁地生产产业用纺织品，不产生水和废水，并且节约能源。 (C) 2013 Elsevier Ltd. 保留所有权利。
Textile dyeing in supercritical carbon dioxide fluid possesses various essential advantages due to water free and no any effluents discharged into environment, etc. In this work, a novel plant in pilot scale was successfully designed and constructed at the first time for fabric rope dyeing with supercritical carbon dioxide fluid for cleaner production of textiles. The employed subsystems and main apparatus of the pilot scale plant, as well as the application procedures and processes for fabric rope dyeing with water free were described. Moreover, primary experiments were carried out for confirming the possibility of fabric rope dyeing in the designed plant with supercritical carbon dioxide fluid. The rope dyeing results show that satisfactory and commercially acceptant products with good color uniformity, wet-wash fastness and rub fastness rated at 4 to 5 were obtained in the pilot scale plant with supercritical carbon dioxide fluid. Moreover, an improvement of color fastness at half or one grade for a deeper shade was observed by employing a rinse procedure after a dyeing step. In comparison with conventional dyeing processes, the plant and application process for fabric rope dyeing were more environmentally friendly and cleaner production of industrial textiles with water and effluents free, as well as energy conservation.
