  • Repeat
  • Hot wash at 90°C with 1g/l Neutral detergent
  • Repeat

  • Cold wash

Hot washes may be increased in case of Dark Shade prints.

Note: In two phase cold dwell method to obtain optimum colour yield of Spectron Turq. Blue G Conc.5.0% urea &/or 1.0% soda Ash in print paste is recommended.

Discharge Printing :

V.S.Based dyes are suitable for discharge printing.Discharge effect is better on cotton fabric than Spun Viscose.Ground shades are prepared by any of the dyeing method and treated with resist salt, 10 gm/l on padder & dried prior to discharge printing. This is to protect the dyed ground shade from reducing effect in the steamers.

GENERAL FEATURES

  • Low Investment cost
  • Suitable for short and long yardages
  • Higher colour yield and fixation
  • Good Penetrating dyeings
  • Salt free dyeing
  • Low chemical, water and energy requirement
  • Low labour and higher productivity
  • Very economical

PREPARATION OF PADDING LIQUOR

The dyestuff is dissolved with minimum requisite amount of hot/boiling water, It is then diluted with cold water, sieved in necessary amount of cold water, temperature must be 40 °C *Urea is added for improving solubility of dye and diluted to 80% of the volume with cold water.

The required quantity of sodium silicate / soda ash and caustic soda are made up to 20% volume with cold water. This gives dye/alkali mixing ratio 4:1

COMPOSITION OF PAD LIQUOR DYE SOLUTION :-
(80% OF TOTAL VOLUME)

  • g/I Spectron Dyes
  • 50-100g/I Urea
  • 1-2g/I wetting agentn

ALKALI SOLUTION :-
(20% OF TOTAL VOLUME)

  • g/I Sodium Silicate or Soda Ash (Refer Tables)
  • m1/I Caustic Soda 38 °Be (32.5%)

PROCEDURE

The dye and alkali solutions are mixed in ratio 4:1 with the mixer and feed to the padder through of small capacity just before padding begins. Control the temperature of pad liquor and fabric (temp 20-25°C), so that pad liquor remains stable. Liquor pickup should be around 60 - 80%for cotton and 80-100% for viscose fabric. Goods are rolled up accurately aligned selvedge and wrapped in plastic film, so that to avoid drying of selvedge and exposing to air. Rotating of large batches during dwell time ensures uniform unwinding in washing Process.

FIXATION

Dwell time of about 18 hours or overnight may be extended up to 36 hours without affecting shade and depth.

AFTER TREATMENT

Continuous washing off sequence on 7 compartment washing machine, using counter current flow principle.

  • 1st bath 40°C with over flow
  • 2nd bath 50-60°C
  • 3rd bath 80°C
  • 4th bath 95°C with addition of 1-2 g/I Sodium hexa meta phosphate
  • 5th bath 95°C with addition of 1-2 g/I Sodium hexa meta phosphate
  • 6th bath 80°C
  • 7th bath 40-70°C
