II p m m e p 2. The flax-cotton-containing fabric from example I is impregnated as in example 1, except that the treatment with a soap-paraffin emulsion is carried out in the presence of 30 g / l HB monochloramine and the final impregnation is carried out with zirconium acetate in terms of zirconium monoxide 20 g / l.

EXAMPLE 3 The flax-cotton-containing fabric of Example 1 is impregnated as in Example 1, except that the treatment with a soap-paraffin emulsion is carried out in the presence of 20 g / l monochloramine and 40 g / l monochloramine T.

EXAMPLE 4 The flax-cotton-containing fabric from Example 1 is impregnated as in Example 1, except that the treatment with a soap-paraffin emulsion is carried out in the presence of 60 g / l, monochloramine B.

PRI me R 5 (control). The flax-cotton-containing fabric from example 1 is impregnated as in example 2, except that the treatment with a soap-paraffin emulsion is carried out in the presence of 10 g / l monochloramine T.

PRI me R 6 (control). The flax-cotton fabric from example 1 is impregnated as in example 1, except that the treatment of dust-paraffin emulsion is carried out in the presence of 70 g / l monochloramine T, and the final zirconium acetate is calculated with 20 g / l zirconia .
