Some Aspects of Bleaching with Hydrogen Peroxide and with Peracetic Acid

The methods and the theory of the bleaching of some of the principal textile fibres with hydrogen peroxide and peracetic acid are discussed. Observations are included on the greater ease of soil removal from bleached wool in relation to washing processes and the rôle of stabilisation in cotton‐bleaching processes. Improvements to existing bleaching methods are given, with particular reference to the use of per acids in kier bleaching, and some data are presented on the decomposition of dilute solutions of peracetic acid.
