Dyeing of Silk Fabric Using Natural Dye Extracted from Sargentodoxa Cuneata and Its Ultraviolet Resistant Property

ABSTRACT

In this research, Chinese herb Sargentodoxa cuneata was investigated as a natural dyestuff to give novel ultraviolet resistance to silk fabrics. The colorant was prepared using sodium hydroxide as extraction solvent, and the properties of the colorant were characterized using fourier transform infrared (FT-IR) and UV-vis spectrophotometric. The functionalized silk fabric was obtained by a typical dyeing process using the prepared Sargentodoxa cuneata extraction (SCE). The effects of dyeing pH, temperature, and time on dyeing properties of silk fabric were investigated. The dyed silk fabric showed excellent UV protection property as well as excellent washing durability. This investigation provides a useful strategy to develop a new class of Chinese herbs with valuable use and silk materials with functional performance.

摘要

本研究以中药大血藤为天然染料，对真丝织物进行了新型抗紫外线染色. 以氢氧化钠为提取溶剂制备了该着色剂，并用傅立叶变换红外光谱（FT-IR）和紫外-可见分光光度法对其性能进行了表征. 利用制备的蛇床子提取物（SCE）对真丝织物进行了典型的染色工艺. 研究了染色pH值、温度和时间对真丝织物染色性能的影响. 染色后的真丝织物具有优异的防紫外线性能和耐洗性. 本研究为开发一类有价值的中草药和功能性蚕丝材料提供了有益的策略.
