After the thread yarn is manufactured, it is wound on dye tubes so it can proceed to one of A&E’s many global dye houses for dyeing. Most of our threads are dyed in package dye machines under pressure.
Different fiber types are dyed with different dye types and temperatures to achieve the desired shade and color fastness requirements.
Polyester threads- Normally dyed with Disperse Dyes at high temperatures (265° F / 129° C) using high energy dyes to ensure good colorfastness.
Nylon threads- Normally dyed with Acid or Chromatic dyes to achieve the desired shade.
Natural fibers including cotton and rayon- Can be dyed with either Vat, Fiber Reactive, or Direct dyes depending on the color fastness requirements and the color shade to be achieved. Generally Vat dyed natural fibers have the best color fastness characteristics.
To ensure uniformity in shade reproduction around the world, A&E uses the same fibers, dyes, chemicals and formulas.
