Cellulose fibers are quite sensitive to the effects of alkaline and oxidative agents-damage occurs mostly during the bleaching process. The presence of some metal ions such as iron, copper, chromium, nickel, and manganese, and their oxides and salts during the peroxide-bleaching process can damage the fabric. In this work, the catalytic metal decomposition of hydrogen peroxide and the effects of any damage that occurs during the bleaching process were investigated, As the decomposition rate of hydrogen peroxide caused by metal ions increases, the amount of oxycellulose/hydrocellulose and fabric damage increases. Manganese (Mn+2) and copper (Cu+2) ions cause more catalytic decomposition than iron (Fe+2 and Fe+3) and other metal ions studied.
