Wool could be bleached using two methods, namely, oxygen and reduction. Oxidative bleachers such as hydrogen dioxide and potassium permanganate could be used. The commonly used one was hydrogen dioxide. The hydrogen dioxide could break down new oxygen and destroy the organic coloring in the wool. It had the characteristics of good whiteness, long-lasting, and not easy to yellow, but it would cause certain damage to the wool. There were two methods of bleaching-dipping and steaming. The dipping and rinsing method was to soak the wool in a solution of hydrogen dioxide at a temperature of 50 ° C for 10 to 15 hours. The concentration of the rinsing solution was determined by the content of the dye in the fiber. The acid can be neutralized by the addition of a solution of either Na-SiO2-SiO3 or NH3-NH2. In addition, it could also be restored and bleached with insurance powder. The requirements were not high, and it would not damage the strength of the wool fiber. However, insurance powder may be difficult to buy in an individual or family.
