Cotton, wool, polyester, and polyamide fabrics have been dyed with the aqueous extract of curcumin, attempting to replace synthetic colorants with natural ones. All dyeing processes were carried out without mordants in aqueous baths in the presence of dispersing agent. It was found that curcumin has high coloristic power on both natural and synthetic substrates offering dark yellow shades. The wash fastness tolerance on all substrates was excellent classifying curcumin as a universal natural dye being able to effectively dye both natural and synthetic fibers, and thus possibly replacing the synthetic and sometimes toxic and allergenic synthetic dyes. It was also found that its antioxidant and antibacterial behavior is considerable, providing useful characteristics to the substrates applied.

棉花、羊毛、聚酯和聚酰胺织物已经用姜黄素的水提取物染色，试图用天然色素代替合成着色剂。所有染色过程均在无媒染剂的情况下在有分散剂的水浴中进行。发现姜黄素在提供深黄色色调的天然和合成基材上均具有高着色力。对所有基材的耐洗牢度非常好，将姜黄素归类为通用天然染料，能够有效地染色天然和合成纤维，因此可能取代合成染料，有时可能会产生有毒和过敏性合成染料。还发现其抗氧化和抗菌性能相当可观，为所应用的基材提供了有用的特性。
