Characterization Assessment of Cotton Fabric Dyed by Dioscorea cirrhosa Dry Extract

ABSTRACT

Dioscorea cirrhosa is a natural plant with advantageous properties in both health care and dyeing. In this work, cotton fabric was dyed with Dioscorea cirrhosa dry extract by the traditional, repeated, dip-spray dyeing process and single-side sunlight fixation method. The color characteristics, surface morphology and structure, chemical composition, and mechanical properties of the dyed cotton fabric were characterized. The flame-retardant and waterproof functions of the dyed cotton fabric were also evaluated. The results showed that the dyed cotton fabric presented the limiting oxygen index (LOI) with one side displaying a reddish-brown coating and the other side being red. The limiting oxygen index of the cotton fabric increased from 18% to 28% after dyeing treatment.

摘要

薯蓣是一种天然植物，在保健和染色方面都具有优势. 在本研究中，采用传统的、重复的浸喷染色工艺和单面日光固定法，用薯蓣干浸膏对棉织物进行染色. 对染色棉织物的颜色特征、表面形态和结构、化学成分和力学性能进行了表征. 对染色棉织物的阻燃和防水性能进行了评价. 结果表明，染色棉织物呈现出极限氧指数（LOI），一侧为红棕色涂层，另一侧为红色. 染色处理后棉织物的极限氧指数从18%提高到28%.
