• Add to Inquiry Basket | Parshwanath offers reactive hot brand dyes. Parshwactive h brand dyes [monochlorotriazine].
parshwactive h brand dyes are monochlorotriazine reactive dyes having a low reactivity and low substantivity. Since these dyes have low reactivity, they requires more severe conditions for fixation with cellulosic materials. They are readily soluble by pouring water of 80º-85º c on powder & stirring well. They are applicable on cellulosic materials by both dyeing as well as printing methods.
in comparison with cold brand dyes, the `h` brand dyes requires either a long steaming time or a high thermofixation temperature [with urea] for optimum fixation. H dyes of low to medium substantivity may lead to migration problem in dyeing prior to fixation.
when low concentration of highly substantive dyes are used, trailing becomes evident. Trailing is avoided by selecting dyes of low or medium substantivity, using small padding troughs fed to constant level and operating at the highest running speed commensurate with the needs of the rest of the process.
these dyes contains very good fastness properties and suitable for printing cotton, viscose, cuprammonium rayons and natural silk.
Method of dyeing
take requisite quantity of water in dye bath [recommended m/1 ratio 1 to 15], heat to 40º c, add common salt or glauber salt, soda ash and 1g/1 of resist. Please requisite dyes with the water and dissolve by adding water at 80º c. Add dissolved dye to the dye bath. Enter material. Run at 40º c for 15 minutes. Raise temp, slowly to 80º c for 45 to 60 minutes, squeeze, wash with water and soap at boil with 2g/l soap, wash with water and dry. Soaping treatment is highly essentional to remove unfixed dye to produce dyeings of high washing fastness.
