3 and comparison examples 1 and 2 are summarized in table 3 the summary in table 3 clearly shows that the polyelectrolytes without hydrophobic groups comparison examples 1 and 2 have higher surface tensions and viscosities than the polyelectrolytes with the highly hydrophobic groups examples 1 to 3 testing of the solution from example 1 as a fibre binder a viscose staple tissue was impregnated with the solution from example 1 by means of a padder squeezed off and then dried at 150 u00b0 c for 3 minutes amount of binder applied 29 5 the strength of the nonwoven impregnated in this way was tested in the transverse direction the tests were carried out with the dry nonwoven and after storage in water or isopropanol for in each case one minute for this in each case 3 strips of nonwoven 150 mm long and 15 mm wide were laid one on top of the other and tested together the measurement conditions were as follows clamped length 100 mm clamped width 15 mm measurement speed 100 mm minute the ultimate tensile stress strength that is to say the maximum tensile force achieved in the context of measurement was documented as the measurement value the measurement results are summarized in table 1 table 1______________________________________ storage in dry storage in h sub 2 o isopropanol______________________________________ultimate 24 7 4 8 23 8 tensile test strength n ______________________________________ it is remarkable that the strength after storage in isopropanol approximately corresponds to the strength of the dry nonwoven testing of the solution from example 1 for antistatic treatment of carpets a needlefelt treated with 30 of binder on the reverse was sprayed with 0 2 or 0 5 based on the amount of binder.
