How to Garment Dye(All-In Method) Cotton Using Orco Reactive BF-Series™ Dyes

  1. This procedure is designed for a liquor ratio of 10-15:1.
  2. Garments should be properly prescoured and/or prebleached.  If the substrate being processed is rayon, do not exceed a pH of 9 as it will cause saponification of the fiber.
  3. Fill machine with water and set bath at 80°F(27°C) adding:

0.5%                      Orconol CHSA Conc™ on weight of goods (owg)

0.5% owg              Sodium Hexametaphosphate

1.0% owg              Orcotol MN Powder™


  1. Add Common or Glauber’s salt, BF-Series™ reactive dye properly prepared, and soda ash as listed in the table below:

% owg Dye                           Salt in oz/gal(g/L)                   Soda Ash in oz/gal(g/L)

0-0.5                                    1.3-2.7   (10-20)                               .67 (5)

0.5-1.0                                 2.7-4.0   (20-30)                               1.33 (10)

1.0-3.0                                 4.0-6.7   (30-50)                               1.33 (10)

>3.0                                     8.0-10.5 (60-80)                               1.33 (10)

    1. For turquoise shades use 2.7 oz/gal(20 g/L) of Soda Ash.
    2. Load garments and run for 10 minutes at 80°F(27°C).
    3. Heat to 140°F(60°C) at a rate of 2°F/minute and run for 30 minutes.
    4. Sample and check for correct shade.
    5. Drain bath and rinse in new bath at 140°F(60°C) for 5 minutes.
    6. In new bath at 100°F-120°F(38°C-50°C), neutralize with 1 g/L(0.133oz/gal) Acetic Acid 56%(or more if necessary for neutralization of residual alkali) for 15 minutes. Drop bath.
    7. In a fresh bath at 140-180°F(60-82°C) and containing 1-2% owg Orcopon KP™, run goods for 20 minutes and drop bath.
    8. Rinse at 140°F(60°C) for 10 minutes.
    9. Rinse cold until clear.
    10. Add fixative or softener if desired.
