Abstract:
This research aims to optimize the silk and wool dyeing process using natural dyes from Bixa orellana (annatto) through response surface methodology. Central composite design experiments highlight the significant enhancement of color outcomes achieved through microwave treatment. For silk, the optimal conditions (80 °C for 40 min) with annatto extract yield a color strength (K/S) of 17.8588, while wool achieves a K/S of 7.5329. Introducing eco-friendly bio-mordants, such as pomegranate peel and red sumac tannins, enhances color strength. Pre-dyeing treatments with 2% red sumac, 1.5% pomegranate peel, and weld flower extracts for silk produce high color strength, with K/S values of 16.4063, 16.3784, and 12.1658, respectively. Post-dyeing, the K/S values increase to 40.1178, 17.4779, and 21.6494. Wool yarn exhibits similar improvements, with pre-dyeing K/S values of 13.1353, 13.5060, and 16.3232, escalating to 10.5892, 15.3141, and 23.4850 post-dyeing. Furthermore, this research underscores improved colorfastness properties, including notable enhancements in light, wash, and rubbing fastness for both silk fabric and wool yarn. These findings underscore the efficacy of the proposed sustainable dyeing methods, offering valuable insights for eco-friendly textile production.
摘要:
本研究旨在通过响应面法使用Bixaorellana(annatto)的天然染料优化丝绸和羊毛的染色工艺。中心复合材料设计实验强调了通过微波处理实现的颜色结果的显着增强。对于丝绸,在最佳条件下(80°C持续40分钟),与红木提取物的颜色强度(K/S)为17.8588,而羊毛的K/S为7.5329。介绍环保生物媒染剂,如石榴皮和红漆树单宁,增强颜色强度。用2%红漆膜进行预染色处理,1.5%石榴皮,和焊接花提取物的丝绸产生高颜色强度,K/S值分别为16.4063、16.3784和12.1658。染色后,K/S值分别增加到40.1178、17.4779和21.6494。羊毛纱线表现出类似的改进,染色前K/S值为13.1353、13.5060和16.3232,染色后上升到10.5892、15.3141和23.4850。此外,这项研究强调了改进的色牢度性能,包括显著的光线增强,wash,丝织物和羊毛纱线的摩擦牢度。这些发现强调了拟议的可持续染色方法的功效,为环保纺织品生产提供有价值的见解。
