    摘要： According to the invention, the process consists of bleaching textile materials from mixtures of cellulosic fibre, such as: (flax-cotton, hemp-cotton) until achieving a whiteness degree of 70-80%, which is carried out in two stages: in the first stage, the materials are treated in aqueous solution containing peroxo-POM catalysts {(NH 4 ) 8 [Mo 10 O 22 (O 2 ) 12 ]; Na 2 [MoO(O 2 ) 2 (C 2 O 4 )]; MoO(O 2 ) 2 ; WO(O 2 ) 2 } in the presence of ionic surfactant and H 2 O 2 , at the temperature of 70-90° C for 60-90 minutes, while in the second stage the material treated in the first stage is suspended in a solution containing 1,5-7 g NaOH, 0,2-1,3 g Na 2 SiO 3 and 0,8-3,2 g H 2 O 2 , for 1-1.5 hours at the temperature of 70-80°C, after which it is washed with cold water until it reaches neutral pH, and then it is air-dried.
