从奥地利温和气候的农业地区获得的植物材料被调查作为纺织染色业务中天然染料的来源。从植物材料中提取染料成分是在沸水中进行的，不添加化学物质或溶剂。在严格选择可能的植物来源的基础上，确定了适用于一浴染色步骤的天然染料的选择。通过将天然染料混合在铁和铝媒染剂的各种组合中，可以实现色度和颜色深度的广泛变化。超过60%的测试染料达到了可接受的牢度性能。在已开发的天然染料染色工艺的基础上，对基于天然染料染色工艺的废水与基于当前“最先进”的合成染料染色工艺的废水进行了比较。比较表明，通过转向植物基染料，可以预期降低废水释放的化学负荷。(C) 2002 Elsevier Science Ltd.版权所有。
Plant materials which are available from farming regions in the moderate Austrian climate were investigated to serve as sources for natural dyes in textile dyeing operations. The extraction of the dye components from the plant materials was performed with boiling water without addition of chemicals or solvents. Based upon a rigorous selection of possible plant sources, a selection of natural dyestuffs applicable in a one-bath dyeing step was established. A broad variation in shade and color depth can be achieved by applying mixtures of natural dyestuffs in various combinations of iron- and alum-mordants. More than 60% of tested dyeings achieved acceptable fastness properties.On the basis of the developed natural dyestuff-based dyeing procedures, a comparison was made between the effluents from processes based upon them and those based upon the current `state-of-the-art' techniques utilizing synthetic dyes. The comparison revealed that a lowering of the chemical load released with waste water can be expected by shifting to the plant-based dyes. (C) 2002 Elsevier Science Ltd. All rights reserved.
