Basing on own studies a comparison has been made between the effect of bleaching base paper with chloraminę T in room temperature, in higher temperature (50°C) in methanol — water solution (1:1) with acetic acid (5 g/1) and citric acid (0.25 and 5 g/1) added. Changes in test paper (Whatman 3 paper) were studied, caused by the action of the above mentioned variants in the conditions ensuring the attainment of a similar effect of brightening. After treatments, the samples were subjected to an artificial ageing by their exposure to a quartz lamp and heating in temperature of 105°C. The evaluation of changes in properties of test paper has been made by an examination of whiteness, pH of water extract, copper no, breaking load, self-breaking and number of douhle bending. The following statements have been made in conclusion: 1. Changes in the paper base caused by solutions of chloraminę T in room temperature should be regarded as insignificant 2. Bleaching with solutions of chloraminę T in higher temperature seems to be the best form of accelerating the proces of paper bleaching 3. Bleaching with chloraminę T in acid medium may be employed only in exceptional cases and only when working with a strong base paper. Acetic acid seems to be better than citric acid as an acidifier 4. Alcohol — water solutions of chloraminę T have been found very useful in paper bleaching. Although the bleaching is then slower, still there is no bigger destructive effect on textiles.
