Dyeing of silk fabric was carried with curcumin, extracted from turmeric, which is known for its yellow colour and antioxidant properties. Design expert Box-Behnken design (BBD) model was employed to perform dyeing experiments on silk fabric with curcumin dye. The dyed fabrics were characterized for its functional properties by colour measurement as K/S values, antioxidant activity by DPPH assay and UPF. The curcumin dyed silk samples showed upto 88% antioxidant activity and good to excellent ultraviolet protection depending on the percentage of curcumin used. The effect of pre-mordanting using metal mordants was also studied.

应用天然黄色（姜黄素）染料在丝绸上赋予多功能整理和使用 BBD 模型验证染色工艺

丝绸织物的染色是用姜黄素进行的，姜黄素是从姜黄中提取的，姜黄素以其黄色和抗氧化特性而闻名。采用设计专家Box-Behnken设计（BBD）模型对丝织物进行姜黄素染料染色实验。染色织物的功能特性通过颜色测量作为K / S值、DPPH 测定和 UPF 的抗氧化活性来表征。姜黄素染色的丝绸样品显示出高达 88% 的抗氧化活性和良好的紫外线防护，具体取决于所用姜黄素​​的百分比。还研究了使用金属媒染剂进行预媒染的效果。
