SARAKOL-RDL |

Leveling agent for cellulosic

Sarakol-RDL is a special formulation for dyeing of reactive dyes and vat dyes by exhaust as well as pad application. Sarakol-RDL improves the solubility of reactive dyes under adverse conditions of dyeings such as low liquor ratio, poor quality of salt, hardness in water, poor solubility of dyestuff. Use of urea can be eliminated by addition of Sarakol-RDL. Hence, BOD values of the effluent can be reduced considerably. 

Sarakol-RDL act as a solubilising and levelling agent particularly for bath dyeing. It does not affect colour value or tone. 

Sarakol-RDL can also be added in print paste to obtain brighter and uniform print.

Application

1. Exhaust process

0.5 - 2 g/l Sarakol-RDL

(Concentration to be added depending on dyestuff and depth of shade)

2. Continuous dyeing

3 - 6 g/l Sarakol-RDL is recommended in the pad liquor for uniformity of the dyeing as well as good bath stability.

3. Grey dyeing of cotton yarn & knits in medium and dark shades with reactive dyes

0.5- 1.0 g/l Celldet-R

0.3- 0.5 g/l Saraquest-W

Treat at 85 deg.C for 15-20 min., cool the bath below required dyeing temperature, 
add 1 g/l Sarakol-RDL

Circulate for 5 mins. and carry out isothermal dyeing as recommended by dyestuff manufacturer.

4. Dyeing of Bleached Yarn in package form

0.5- 0.7% Sarakol-RDL - regular dyes

1 - 1.2% Sarakol-RDL - critical & poor solubility dyes

5. Print Paste

0.3-0.5% Sarakol-RDL

Note:

For all above processes half quantity of Sarakol-RDL to be added during dissolving of the dyestuffs and balance quantity to be added in the dyebath/padding liquor.

Storage : Store in cool, ventilated shed away from heat and direct sunlight. Storage temperature should not exceed 35 deg C.Close lids firmly to avoid contact with air and moisture.

Shelf Life : 9 months from the date of manufacturing, if stored under controlled conditions.
