  • Example 3 The procedure described in Example 3 is followed and a printing paste is used which is 480 g / kg Na alginate medium viscosity (6% batch containing 5 g / kg sodium hexametaphosphate and 3 g / kg 37% formaldehyde) instead of 480 g / kg Na alginate medium viscosity (6% batch containing 5 g / kg sodium hexametaphosphate and 5 g / kg 37% formaldehyde), 30 g / kg 1% aqueous solution of a copolymer of approx. 15% acrylic acid and 85% acrylamide (molecular weight approx. 2 million) instead of 75 g / kg 0.8% aqueous solution of a copolymer of approx. 15% acrylic acid and 85% acrylamide (molecular weight approx. 2 million) and 212 g / kg water instead of 167 g / kg water, similarly good results Get results.
  • the printing paste has a viscosity of approx. 5,000 mPa.s, measured on the Brookfield RVT viscometer, spindle 6, 20 rpm at 25 ° C.
  • the printed fabric is dried at 70 to 80 ° C and for 10 minutes to fix the dye. treated with saturated steam at 100 to 102 ° C.
  • the tissue is rinsed with cold water and then 5 min. treated at 50 ° C with 2 g / l H2O2 35% and 1 g / l acetic acid 80%.
  • the reoxidized tissue is then rinsed with warm water, soaped at the boil for about 5 minutes and rinsed again with warm and cold water. After drying the fabric at 60 to 100 ° C, you get a strong, level, olive-colored print with sharp contours.
  • the treated fabric also has a soft feel.
  • the printing paste has a pH of 6.1.
  • the viscosity is approx. 5,400 mPa.s, measured on the Brookfield RVT viscometer, spindle 6, 20 rpm at 25 ° C.
  • the printed fabric is dried at 70 to 80 ° C and for 8 minutes to fix the dye. treated with saturated steam at 175 ° C.
  • the fabric is rinsed with cold water, soaped at 40 ° C with 1 g / l of a nonionic fatty acid ethoxylate and then at 40 to 70 ° C with 1.5 g / l Na2S2O4, 2 g / l sodium hydroxide solution 36 ° Bé and 1 g / l of said fatty acid ethoxylate reductively cleaned.
  • the treated fabric also has a soft feel.
  • the printed fabric is dried at 70 to 80 ° C and to fix the dye for 35 min. treated with saturated steam at 100 to 102 ° C. To finish, the fabric is rinsed with cold water, soaped at 30 ° C and rinsed cold again. After the fabric has dried, it contains a strong, level, green print with sharp contours. The treated fabric also has a soft feel.
