High molecular weight water soluble polyester based anionic multifunctional single product for dispersing & leveling of disperse dyes on substrates like polyester fibers, yarns and fabrics.

It is a combination of two products RFT-100 (S) + RS-75. It is made by using RFT-100 (S) water soluble polyester resin which is 100% solid in granule form and surfactant system RS-75. The combination of RFT-100 (S) along with RS-75 and dilution gives you RFT-250 (S), ready to use dispersing leveling agent 25% for solid. RS-75 can also be used on its own as a dispersing leveling agent in very hard water conditions where RFT-250 (S) may not be suitable. This single component auxiliary can compete existing auxiliaries at ease with better performance and economics.

Benefits to the customer:

1. Optimized polymeric system for dispersion, migration and leveling.

2. Excellent dyeing results.

Load the fiber/yarn/fabric and fill the machine with water as per MLR. 2. Raise the temperature to 45°C add acetic acid, acid buffer, sequestering agent & anti- creasing as per the given recipe. Hold for 10 minutes at same temperature 3. Check the pH ( it should be around 4-5.45) and raise the temperature to 55°C 4. Add RFT-250 (S) solution at this temperature and hold for 5 minutes 5. Raise the temperature to 55°C and then add properly dissolved and filtered disperse dyes solution gradually within a period of 10 minutes and then hold the temperature for another 10 minutes 6. Start raising the temperature as per the rate given in the above recipe and hold for 25 min at 135°C 7. Check the sample shade and then cool or drain the dye bath and proceed for R.C. Important points for getting the best results Preferably only acid should be used along with RFT-250 (S). In case one has to use other products like sequestering agent, de-foamer, dispersing powder, carrier, acid buffers please check the compatibility of the system. Never mix acid directly with RFT-250 (S). Never use RFT-250 (S) directly. Use diluted product as per recipe Please filter the solution before use as it forms fibrous precipitate on long storage.
