Effect of Binary and Ternary Combination of Metal Salt Mordants on Dyeing and Fastness Properties of Natural Protein Fibre with Juglans regia L. Dye

ABSTRACT

The present article focuses on the effect of different combinations of metal mordants on color characteristics and fastness properties of natural dye extracted from Juglan regia L bark powder. The influence of different types of mordant combinations such as alum + ferrous sulphate, alum + stannous chloride, ferrous sulphate + stannous chloride, and alum + ferrous sulphate + stannous chloride on color parameters has been investigated in terms of CIELab (L*, a*, b*, c*, and h°) and K/S values. The fastness properties with respect to light, washing, and crocking of developed shades were determined according to ISO and AATCC test methods. Based on the experimental results, it has been found that 96 shades with novel and fashionable hues were produced by the use of these metal salt combinations. It was also found that all mordanted samples had satisfactory light and wash fastness ratings. Dry rub fastness was found relatively better than wet rub fastness.

摘要

本文重点研究金属媒染剂的不同组合对从胡桃 L 树皮粉末提取的天然染料的颜色特性和色牢度的影响。在研究中，使用 CIELab（L*、a*、b*、c*和h°）以及K/S值，度量不同类型的媒染剂组合（如颜料+硫酸亚铁、明矾+氯化亚锡、硫酸亚铁+氯化亚锡以及明矾+硫酸亚铁+氯化亚锡）对颜色参数的影响；使用 ISO 和 AATCC 测试方法测定与光、洗涤和摩擦显影有关的色牢度。实验结果表明，使用这些金属盐组合可产生新颖、时尚的 96 种色调，所有媒染样品具有令人满意的耐光牢度和耐洗牢度，而且干摩擦牢度相对优于湿摩擦牢度。
