SARASOL-763 | Pre-treatment for Digital Printing of Viscose

Sarasol-763 is a high viscosity thickening agent which is applied in the pre-treatment process of Ink-Jet printing. Sarasol-763 gives sharp and even prints with improved colour values especially on viscose and cellulosic substrates. It also delivers even and sharp prints on the substrates printed with disperse and acid dyes. Sarasol-763 does not affect the original hand of the fabric. The quality of the final print obtained with Sarasol-763 is much better than that obtained with conventional thickeners.

1. Ink-Jet printing on Cotton or Viscose (Reactive ink)

Pre-treatment

• Pre-treatment : 40-60 g/l (Cotton) 60-80g/l (Viscose)
• Sarakol-NF : 1-5 g/l
• Urea : 50-100 g/l
• Soda ash : 30-40 g/l
• Super R Salt : 10-20 g/l

Pad -> Dry -> Print (Ink-Jet printing)

Ink-Jet Printing

• Printing : Ink-Jet with Reactive ink
• Steaming : 102-105 deg.C, 7-10 min. OR

After treatment (Washing)

• Cold wash : 5 mins.
• Soaping : 1 g/l Sarakol-CR, 98 deg.C, 5 mins.(twice)
• Hot wash : 3 mins at boil (twice)
• Cold wash : 5 mins.

2. Ink-Jet printing on Polyester (Disperse ink)

   Pre-treatment (Padding)

• Sarakol-CL : 60-80 g/l
• Sarakol-NF : 1-5 g/l

Pad -> Dry -> Print (Ink-Jet printing)

Ink-Jet Printing

• Printing :Ink-jet with disperse ink
• Steaming : 170-180 deg.C, 8 min. OR
• Calendering : 200-210 deg.C, 30 sec.

After-treatment (washing)

• Cold wash : 5 mins.
• Soaping : 1 g/l Sarakol-CR at 40 deg.C, 5 mins.
• Reduction clearing : 0.75-1 g/l, Reducon-ACD (Conc) at
                                   4.5-5.0 pH, 60-70 deg.C, 10 mins.

3. Ink-Jet printing on Silk, Wool, Polyamide (Acid ink)

Pre-treatment

• Sarasol-763 : 60-80 g/l
• Sarakol-NF : 3-8 g/l
• Urea : 80-100 g/l
• Ammonium sulphate (25%) : 10-20 g/l
• Supergen-MX  : 10 g/l

Pad -> Dry -> Print (Ink-Jet printing)

Ink-Jet Printing

• Printing : Ink-Jet with Acid ink
• Steaming : 102-105 deg.C, 10-20 mins.followed by washing

In case of Polyamide / Wool, fixation with 0.4-1.5 g/l Sarafix (NEW), pH 4.5-5.5 at 70-80 deg.C for 15-20 min is recommended.

1. Sarasol-763 can be applied by coating with 50% diluted product.
2. Concentration of Sarakol-NF to be added depending on GSM of fabric. For lower GSM fabric, lesser quantity of Sarakol-NF is required compared to higher GSM fabric.

Precautions

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.
