Effect of Spraying FeCl3 on the Pigment Fixation in the Natural-colored Cotton Fiber Abstract£ºThe study was undertaken on natural-colored cotton cultivars, which were Xiangcaimian 2 and Wanmian 39 at the Jiangsu Provincial Key Laboratory of Crops Genetic and Physiology, Yangzhou University, Yangzhou, China. In the experiment, the brown cotton cultivar (Xiangcaimian 2) and the green cotton cultivar (Wanmian 39) were grown and investigated to study the effect of spraying FeCl3 on the pigment fixation in the natural-olored cotton fiber. The results showed that spraying FeCl3 increased the pigment's stability of the natural-colored cotton cultivars significantly, especially for Wanmian 39. In compared with each control, spraying FeCl3 increased the absorbency of the pigment solution for Wanmian 39 and Xiangcaimian 2 by 75.5% and 44.9% respectively after five hours in the radiation of sunlight. The results further revealed that spraying FeCl3 increased the iron concentration in the natural-colored cotton fiber. Compared to each control, the content of iron in the fiber increased for Wanmian 39 and Xiangcaimian 2 by 21.47% and 11.89% respectively. Significant correlation was found between the iron concentration and the declining amount of the pigment solution absorbency in sunlight (r=0.953, p<0.01).The experiment indicated that spraying FeCl3 can increase the iron concentration in the fiber for different natural-colored cotton to enhance the pigment's stability.
