Abstract

This study investigates the application of Hymenocrater platystegius flower as a natural mothproofing agent for wool fibers and examines the effects of aluminum mordanting on the dyeing properties of wool treated with various natural dyes. Wool fibers were treated with Hymenocrater platystegius flower powder and aluminum salts, followed by dyeing with Madder, Reseda lutea, Indigo, or Walnut shell dyes using different mordanting methods. FTIR analysis revealed the characteristic absorption bands and confirmed the interactions between the wool fibers and the treatment agents. The insect-repellent properties were assessed by weight loss measurements after exposure to Anthrenus verbasci larvae, showing significant improvements in treated samples, particularly with the combination of Hymenocrater platystegius and aluminum mordanting. GC–MS analysis of the essential oil identified as α-Pinene, Trans-Verbenol, Linalool, and β-Bourbonene as the main constituents, contributing to the insect-repellent effect. The L*a*b* color space analysis demonstrated that aluminum mordanting significantly enhances the color strength and stability of dyed wool, with pre-mordanting generally providing better results. The study further evaluated the washing and light fastness, as well as the mothproofing properties of the dyed wool samples. These results indicate that the weight loss percentages of treated wool fiber after washing are slightly higher than before washing, but the difference is not significant. Overall, the use of aluminum mordant in conjunction with Hymenocrater platystegius flower powder not only improves the color characteristics of wool dyed with natural dyes but also provides effective mothproofing properties, making it a viable and eco-friendly option for textile applications.

利用 Hymenocrater platystegius 花和天然染料对羊毛纤维进行可持续改良,以提高防虫性和色彩特性
本研究探讨了羊毛纤维天然防蛀剂海门螺杆菌花的应用,并研究了铝媒染对羊毛经各种天然染料处理后的染色性能的影响。羊毛纤维先用板蓝根花粉和铝盐处理,然后用不同的媒染方法染上马德德、Reseda lutea、靛蓝或胡桃壳染料。傅立叶变换红外光谱分析显示了特征吸收带,证实了羊毛纤维与处理剂之间的相互作用。通过测量暴露于 Anthrenus verbasci 幼虫后的重量损失,对驱虫特性进行了评估,结果表明处理后的样品具有显著的驱虫特性,尤其是在结合使用 Hymenocrater platystegius 和铝媒染剂的情况下。精油的气相色谱-质谱分析表明,α-蒎烯、反式萜烯醇、芳樟醇和 β-香椿烯是驱虫效果的主要成分。L*a*b* 色空间分析表明,铝媒染能显著提高染色羊毛的着色力和稳定性,而预媒染通常能获得更好的效果。研究进一步评估了染色羊毛样品的耐洗牢度、耐光牢度和防蛀性能。结果表明,经过处理的羊毛纤维在洗涤后的失重率略高于洗涤前,但差异不大。总之,将铝媒染剂与 Hymenocrater platystegius 花粉结合使用,不仅能改善天然染料染色羊毛的颜色特性,还能提供有效的防蛀性能,是纺织品应用中一种可行的环保选择。
