UV Protection and Dyeing Properties of Wool Fabrics Dyed with Aqueous Extracts of Madder Roots, Chamomiles, Pomegranate Peels, and Apple Tree Branches Barks

ABSTRACT

This paper studies the dyeing properties of wool fabrics dyed with aqueous extracts of madder roots, chamomiles, pomegranate peels, and apple tree branches (obtained after pruning) barks. We have thoroughly investigated the effects of dye bath pH and mordants on the color properties of the aforementioned fabrics. Even without mordanting, the wool fabrics dyed with the pomegranate peel have the highest value of color strength (K/S = 14). Mordanting permits to produce different colors and improve the fastness of a dye, especially for madder roots, chamomile, and apple tree branches bark. UV protection of wool fabrics increased after natural dyeing, and it was more improved after mordanting especially with ferrous sulfate. Experimental results show that the fastness properties of dyed wool fabrics range from average to excellent even without mordanting.

摘要

研究了茜草根、甘菊、石榴皮、苹果树枝(修剪后得到)树皮水浸液对羊毛织物的染色性能. 我们深入研究了染液pH和媒染剂对上述织物颜色性能的影响. 用石榴皮染色的羊毛织物即使不经霉染，其色强值也最高(K/S = 14). 媒染允许产生不同的颜色和提高染料的牢度，特别是茜草根，洋甘菊和苹果树树枝的树皮. 羊毛织物经自然染色后防紫外线能力增强，经硫化亚铁染色后防紫外线能力增强. 实验结果表明，经染色后的羊毛织物的耐染牢度从一般到优良不等.
