Color Change in Indigo Dyed Fabrics by Dyeing Conditions and the Result of Treatment

研究了染色条件和加热条件对干态和湿态变色的影响。通过改变染色温度，可以对不同颜色的深蓝色织物进行染色。在湿热条件下，织物的颜色会发生变化。并考察了不同溶剂对织物的浸泡效果。在甲醇和含水的溶剂中观察到颜色的变化。此外，还研究了蓝染织物光褪色的差异。研究发现，褪色的速度取决于织物中蓝色的状态。

The influence of dyeing conditions and heating to the color change under dry conditions and wet conditions has been investigated. Indigo fabrics of different color could be dyed by changing dyeing temperature. Under wet and hot conditions color of the fabrics has changed. Effect of soaking the fabrics in various solvent was also examined. Color change was observed in methanol and the solvent containing water. Difference in photofading of indigo dyed fabrics has also been investigated. The rate of the fading was found to depend on the state of indigo in the fabrics.
