Applications:
Reactive dyeing and prints : After normal post dyeing or printing operation the goods shoud be thoroughly soaped for removing unfixed colour to the desired extent and then shoud be treated with 30-45 mins. 0.5-1.0% (owg) of HEFIX DF A at pH 5.0 to 5.5 adjusted with acetic acid. A slightly warm (40 c to 45 c) bath enhances speed of process.
In case of hosiery goods or yarn : exhaustible cationic finishing agent can be applied in same bath along with dye fixing agent, however pre-trials are required to ascertain compatibility chemicals involved.
Storage:
Stable under normal conditions. |
