Deep-dyeing auxiliary that turns cotton jet-black (newly developed)
Builder C-DM
(A) Black reactive-dyed cotton
(B) Black reactive-dyed, padded with Builder C-DM and dried.
[Properties]
A deep-dyeing auxiliary is used mainly for improving the depth of shade in the aftertreatment of polyester dyeing in black, navy, blue or dark green. With Builder C-DM, deeper shades can be expected even from reactive dyestuff. Moreover, its deep-dyeing effects are superior in durability and dyeing fastness. Although deep-dyeing effects as obvious as those on polyester may not be expected, Builder C-DM remarkably enhances brightness in reactive dyeing.

[Features]
- Produces superior deep-dyeing effects. Being composed of a special resin compound with self-crosslinking properties at a low refractive index, it forms a crater-shaped, low-refractive micro film on the surface of fiber. This results in enhanced light transmission to the fiber with less reflection (white light), thereby producing a deeper shade.
- Displays superior durability in the deep-dyeing effect. Has superior colorfastness to washing and dry cleaning due to self-crosslinking properties.
- Influences on colorfastness are minimal.
- Due to the main component being resin, the processing liquor does not suffer from gumming up or any alteration during treatment, unlike conventional silicone types.
