Abstract

There is a growing demand for eco-friendly and non-toxic dyes that can be used to impart color to a wide variety of materials. Synthetic dyes are known to cause health hazards due to possible carcinogenic effects associated with azo dyes, high heavy metal content and the possible use of other restricted substances. The present study aims at the cultivation of fungi utilizing agricultural wastes and extraction of colors there from. The bio-colorants thus obtained were subjected to characterization using analytical techniques like FTIR, TGA and particle size analysis. The characterized bio-colorants were further exploited for dyeing of cow crust, and parameters like color fastness, rub fastness and heat resistance were analyzed. Out of the four bio-colorants, yellow was potential to be used as dye solution, while the remaining black, brown and green were good for surface coating of cow crust.

农业残留物以提高生物色素的产量：皮革染色和表面涂层的可行方法

摘要

人们对可用于赋予多种材料以颜色的环保且无毒的染料的需求不断增长。已知合成染料会造成健康危害，原因是与偶氮染料有关的可能的致癌作用，高重金属含量以及可能使用其他受限物质。本研究旨在利用农业废弃物栽培真菌并从中提取色素。使用诸如FTIR，TGA和粒度分析的分析技术对由此获得的生物着色剂进行表征。将特征化的生物染料进一步用于牛皮的染色，并分析了色牢度，耐擦牢度和耐热性等参数。在四种生物着色剂中，黄色有可能用作染料溶液，而其余的黑色，
