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

本文研究了用茜草根、洋甘菊、石榴皮和苹果树枝（修剪后获得）树皮的水提物染色的羊毛织物的染色性能。我们彻底研究了染浴 pH 值和媒染剂对上述织物颜色性能的影响。即使没有媒染，用石榴皮染色的羊毛织物的色强值也最高（K/S = 14）。媒染剂可以产生不同的颜色并提高染料的牢度，特别是对于茜草根、洋甘菊和苹果树枝树皮。羊毛织物在天然染色后的紫外线防护能力增强，而在经过媒染特别是硫酸亚铁之后，其抗紫外线性能得到了更好的提高。
