General Product Specifications:
Disperse dyes in this group are used for the following synthetic fiber: Acetate, Nylon, Lycra and Acrylic. They are used in an atmospheric dyebath, but do not require boiling for wash-fastness. For this reason, they are known as "low energy" disperse dyes.
They are very level dyeing, making them easy to control. The disperse dyes have a strong affinity for the fiber, and require no additional agents.
They can also be painted directly onto the fabric or printed and then steam set.
Preparation of the Fabric:
Fabric should be washed and be as absorbant as possible prior to dyeing. Remove sizing from cloth by washing in Aljo WA-6 surfactant, or commercial detergent.
Dyeing Procedure:
Use a stainless steel or enamel vessel for dyebath liquor.
Measure amount of dye by weight, according to weight of goods (owg), and the depth of shade desired.
Completely dissolve the dye in a small amount of boiling water to make a concentrate. Add the concentrated paste to the volume of water needed for the fabric to move freely.
Set the dyebath temperature at 120°F.
Enter the pre-washed damp fabric.
Increase dyebath temperature up to 180 to 200°F. over twenty minutes.
Stir frequently to assure level dyeing.
Continue to run dyebath for 10 to 20 minutes to complete exhaustion.
Allow temperature to drop to 140°F. Before removing from dyebath.
Remove fabric and rinse in warm water. Rinse again with a little detergent to extract excess dye.
