Improving the color features of hemp fibers after chemical preparation for textile applications

The renewed interest in bast fibers for textile products has focused attention on research in different methods of bast fiber processing. The color properties of bast fibers must be improved during fiber preparation, especially when standard textile processes such as cotton and wool methods are considered. The color properties of hemp fibers are investigated in this paper after chemical processing based on experimental design techniques. The effects on the fiber color of hemp raw materials and chemical processes are discussed. The results of alkali boiling and peroxide bleaching are analyzed for their significant effects on hemp fiber color.
