食品和饮料行业释放出大量含有天然染料的废物。这些废物可以作为提取天然染料的来源，用于纺织品染色作业。从水果和蔬菜中提取鲜艳的黄色和红色是特别令人感兴趣的。用沸水浸提压榨浆果、压榨葡萄、烈酒生产的蒸馏残渣和蔬菜加工的废料和果皮等废料，并对羊毛纱线进行染色试验。测试了染色的色强度、色光和牢度。提取物作为直接染料，并在铁（II）或明矾媒染剂的存在下。结果证明了这种废物作为天然染料提取来源的潜力。然而，为了获得具有可接受的牢度性能的纺织品染色，需要严格选择染料和开发合适的工艺。相当多的红色天然染料需要进一步研究，以优化低水平的耐光牢度。版权所有© 2005化学工业协会
The food and beverage industry releases considerable amounts of wastes which contain natural dyes. Such wastes could serve as a sources for the extraction of natural dyes for textile-dyeing operations. The extraction of brilliant yellow and red colours from fruits and vegetables is of particular interest. Wastes, e.g. pressed berries, pressed grapes, distillation residues from strong liquor production, and wastes and peels from vegetable processing, have been extracted with boiling water and test dyeings on wool yarn were performed. Colour strength, shade and fastness properties of the dyeings have been tested. The extracts were applied as direct dyes and in the presence of iron(II) or alum mordants. The results prove the potential of such wastes as a source for natural dyestuff extraction. To obtain textile dyeings with acceptable fastness properties, however, rigorous selection of dyes and development of suited processes is required. A considerable number of red natural dyes need further research to optimise the low level of fastness to light. Copyright © 2005 Society of Chemical Industry
