Extraction of natural dye from ebony tree and its performance on cotton fabrics

天然染料的牢度性能差。媒染剂的加入提高了其牢度性能。乌木是提取天然染料的宝贵资源。乌木树皮能使纺织品呈现出良好的棕色。从乌木树皮中提取染料,并在添加媒染剂的情况下,采用染料对纯棉织物进行染色,对染色试样进行各种牢度测试。所有染色试样均表现出良好的牢度性能。

Natural dyes are poor in fastness properties.The inclusion of mordant increases the fastness properties.The ebony tree is a valuable resource for extraction of natural dyes.The bark of ebony tree gives a very good brown color to textiles.The dye was extracted from the bark of ebony tree and it was applied on 100%cotton fabric in the presence of mordant.The dyed samples were subjected to various fastness testing and the dyed samples exhibited very good fastness properties.
