摘要： A process for the bleaching of dyed textiles with peroxygen compounds is provided. The process comprises contacting the textiles with an aqueous solution of an iron salt, an aqueous solution of a peroxygen compound and subsequently an aqueous solution of a sequestrant for iron. The peroxygen compound can include Caro's acid, hydrogen peroxide, sources of hydrogen peroxide including sodium percarbonate and sodium perborate mono and tetrahydrates, low molecular weight alipathic peracids such as C1 to C6 alipathic peracids, especially performic, peracetic or perpropionic acid, and persulphate salts, including sodium, potassium and ammonium perdisulphates and potassium permonosulphate, and is preferably Caro's acid, hydrogen peroxide, peracetic acid or a persulphate salt. The process is particularly suitable for the bleaching of denim.
