Americos Dispersol DX is anionic dye dispersing agent. It prevents dyestuff
agglomeration and prevents precipitation in dye bath.
The Features of Americos Dispersol DX are :
- Dispersing agent for use in the dyeing of polyester
- Dyeing polyester/wool blends with disperse and acid or 1:2
metal-complex dyes or corresponding dyestuff blends
- Dispersing agent in dyeing with vat dyes
- Dyeing of triacetate fibers with disperse dyes
- Low foaming
- Stable at HT and shows no retardant influence on dyestuff
Dyeing of polyester and triacetate fibers with disperse dyes
Americos Dispersol DX is a dispersing agent used to disperse dyes in the
preparation bath before dyeing and to maintain the stability of the
dispersion during dyeing. The amounts required are 2 g/l Americos Dispersol
DX in the preparation bath and 0.5-2 g/l in dye baths, depending on depth of
shade and liquor ratio.
Application Method :
Dyeing cellulosic fibers with vat dyes
- Preparation of the dye bath liquor. Sprinkle disperse dyes into 10-15
parts soft water (30° - 40 °C)
containing dissolved Americos Dispersol DX and stir continuously. Dilute
further with water. This liquor is then added to the dye bath.
- Application in the dye bath to maintain the stability of the
dispersion during dyeing, add 0.5-2 g/l pre-dissolved Americos Dispersol
DX, depending on depth of shade and liquor ratio, to the warmed dye
bath. Then add the normal amounts of carrier required for dyeing at the
boil or leveling agents required for HT dyeing. Add thoroughly dispersed
dye as usual.
When dispersing large quantities of dyes, it is advisable to add 1.5-3 g/l
Americos Dispersol DX. When working with vat dyes, Americos Dispersol DX
improves the levelness of pigmentation, especially on circulating liquor
units. For the exhaust, pigmentation and half-pigmentation processes, add
1.5 - 3 % Americos Dispersol DX
Dyeing polyester/wool blends
Americos Dispersol DX is required to ensure that the dyes remain finely
dispersed throughout the dyeing process. This is particularly important when
dyeing wound packages and at short liquor ratios. Americos Dispersol DX also
has good leveling action on 1:2 metal complex dyes.
Application Method :
Heat the liquor to 30-40 °C and add 1-2 % Americos Dispersol DX
(pre-dissolved). Then add acetic acid and the carrier. When the acid and
auxiliary have been dispersed evenly, add the well-dispersed or dissolved
dyes. Dye and finish as usual.
Storage & Handling Precautions:
- In accordance with the current practices, the
use of Americos Dispersol DX produces no ill effects. It also does not
