SARASOL-CL | Pre-treatment for Digital Printing of cellulose

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

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

Pre-treatment

• Sarasol-CL :  50-70 g/l (Cotton) 70-90g/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-CL : 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

Incase 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-CL 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.
