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.

Dyeing Procedure:
|
|
1.
|
|
Use a stainless steel or enamel vessel for dyebath liquor.
|
2.
|
|
Measure amount of dye by weight, according to weight of goods (owg), and the depth of shade desired.
|
3.
|
|
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.
|
4.
|
|
Set the dyebath temperature at 120°F.
|
5.
|
|
Enter the pre-washed damp fabric.
|
6.
|
|
Increase dyebath temperature up to 180 to 200°F. over twenty minutes.
|
7.
|
|
Stir frequently to assure level dyeing.
|
8.
|
|
Continue to run dyebath for 10 to 20 minutes to complete exhaustion.
|
9.
|
|
Allow temperature to drop to 140°F. Before removing from dyebath.
|
10.
|
|
Remove fabric and rinse in warm water. Rinse again with a little detergent to extract excess dye.
