Introduction :
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

Properties :

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 :

1. 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.
2. 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.

Dyeing cellulosic fibers with vat dyes
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 exert any harmful effects on health, provided they are used properly
• Protect the eyes and avoid prolonged contact with the skin. Safety glasses should be worn when handling these products in their undiluted form
• Store in a cool place, avoid storing in direct sunlight
• The usual precaution for chemicals should be observed
• Shelf life: If Americos Dispersol DX is stored properly, it has a shelf life of at least two years in their original packing.

Introduction :
Americos Extracta AL is highly concentrated solvent-based emulsifying and wetting agent. It is recommended for scouring process of all fibers. It removes all hydrophobic and oily impurities from fabric at low temperature.

Americos Extracta AL is recommended for batch process.

The most outstanding effects of Americos Extracta AL:

• Excellent scouring agent with good wetting and detergent action.
• Removes oily contamination and sizes of all types producing a high degree of purification and good absorbency
• It works excellent at low temperatures also

Properties :

Appearance	Clear, colorless to light yellow
Chemical character	Fatty alcohol alkoxylates and solvent
Ionic nature	Nonionic
pH (1% dilution)	7
Stability to hard water	Good

Compatibility with :

Anionic/nonionic/ cationic substance	Good
Enzyme compatibility	Not good
Foam formation	Moderate

Mode of action :
Americos Extracta AL wets out, washes, extracts, emulsifies, disperses and makes impurities soluble/removable in all suitable continuous and discontinuous stages of pretreatment

Americos Extracta AL has an emulsifying effect even at room temperature, e.g. on mineral oil contamination, so that it becomes readily removable by subsequent hot rinsing.

Application :
1 - Scouring :

• 5-30g/l Americos Extracta AL
• 40-60g/l caustic soda (100%)
• Pad the fabric with above recipe at 70-80% pick -up and steam for 10-20 min. Then give hot rinse and cold rinse in compartmental washing units

Discontinuous: (liquor ratio 1:8-1:20)

• 2-5g/l Americos Extracta AL
• 2-4g/l soda ash o 3-8g/l caustic soda 100%
• Heat to boil, hold 30-60 min. Give one hot rinse and one cold rinse.

Storage & handling precautions :

• Store in a cool/dry place
• Avoid storing in direct sunlight
• The shelf life of Americos Extracta AL is one year, if storage temperature is below 30°C
• The usual storage, handling, usage and safety precautions should be observed
