First-time application of biomordants in conjunction with the Alkanna tinctoria root extract for eco-friendly wool dyeing

ABSTRACT

Associated environmental hazards with the use of synthetic dyes and toxic metal mordants in the textile industry lead to concerns for alternatives. Natural dyes and biomordants are the new eco-friendly and biocompatible resources for textile coloration obtained from never-ending natural flora. The coloration potential of naphthoquinone-based colorants from Alkanna tinctoria roots on wool was investigated in this study with the application of both metallic mordants as well as biomordants. Color characteristics were evaluated on a spectrophotometer under the D65 illuminant, 10° standard observer, and fastness properties by using standard methods. A wide range of shades was obtained with good color characteristics and fastness results. Iron among metallic mordants, pomegranate peel extract (PPE) and babool among biomordants increased the color yield of dyed wool. Scanning electron microscopy (SEM) confirmed the undamaged physical structure and surface morphology of dyed wool.

摘要

相关的环境危害与合成染料在纺织工业中的有毒金属媒染剂的使用导致问题的替代品。从没有结局的自然植被得到纺织染色的新型生态环保、生物相容性和生物资源的天然染料媒染剂。羊毛从alkannatinctoria根基于naphthoquinone着色剂着色的潜力进行了研究与金属媒染剂以及生物剂的应用。在分光光度计在D65光源进行颜色特征，10o标准观察者和牢度性能通过使用标准的方法。获得了多种色调，具有良好的色彩特性和牢度效果。在铁金属媒染剂，石榴果皮提取物（PPE）在生物媒染剂染色羊毛的颜色 Babool增加产量。扫描电子显微镜（SEM）证实了未染色的羊毛的物理结构和表面形态。
