A process for bleaching fibers, particularly animal fibers which become damaged if their temperature rises too high, by applying to them a bleaching agent such as hydrogen peroxide the bleaching reaction of which releases heat sufficient to raise the temperature of the fibers above the temperature at which the fibers become damaged, in which the heat released by the reaction is absorbed by a material added in solid, powder, liquid or gaseous form to the fibers. The added material undergoes a chemical or physical change (such as a change of state) upon absorption of heat without rising in temperature. This allows the fibers to be held in bulk during bleaching without requiring to be spread out for the purpose of heat dissipation.
