“…For choosing the suitable mordanting agent for the yak wool, the yak wool was mordanted with the concentration of 1⋅10 -4 mol⋅L -1 of transition metal salts with the concentration of 6 g•L -1 of citric acid, which was used as an auxiliary reagent at 50°C for 25 min. Following that, the bleaching stage was carried out by adapting the same bleaching condition previously reported [18].…”

Yak wool is a smooth, warm, and durable natural protein-structured fiber that could compete with cashmere and other high-end protein-structured fibers on the market. However, it suffers from drawing consumers’ attention due to the lack of color due to the shortfall of the yak wool bleaching technology. Herein, we studied the applicability of various transition metals, i.e., copper (II), cobalt (II), iron (II), and nickel (II) salts, as a mordanting reagent based on their effect on the hydrogen peroxide decomposition reaction and the morphological and mechanical properties of the bleached yak wool with the presence of these transition metal. Our study suggested that the iron (II) ion was the most efficient reagent for the mordant bleaching since it provided less fiber damage, relatively high strength, and elongation to the bleached yak wool with good whiteness, while the Cu (II) was the least favorable agent for the yak wool bleaching process.

“…Yak hair is a precious agricultural by-product for textile, showing great economy value such as fine elasticity, high tenacity, warmth, and proper moisture absorption [3] , [4] . Yak hair merely owns a quarter price of cashmere but with similar thermal conductivity and elasticity [5] . The global yak population reached over 15.2 million, and ca.…”

“…Currently, very few studies attempt to bleach yak hair using ferrous (Fe 2+ ) ions as catalyst and hydrogen peroxide (H 2 O 2 ) - a safe and eco-friendly bleaching reagent [3] , [5] . The generation of reactive oxygen species (ROS) - hydroxyl radicals (HO•) from H 2 O 2 is responsible for the disintegration of melanin.…”
