These dyes react with cellulosic fibres in presence of alkali & heat.The direct chemical linkage which result therby accounts for excellent fastness. The reaction between cellulosic fibres and Spectron range of dyes can be achieved by any of the follwoing methods.

  1. ONE PHASE METHOD
    • Steaming Process
    • Dry Heat Process
  2. TWO PHASE METHOD
    • Sodium Silicate

After Treatment :

  • Rinse in cold water with overflow.
  • Rinse at 40°C with 1g/l SHMP water (Easy removal of silicate)
  • Repeat
  • Hot wash at 90°C with 1g/l Neutral detergent
  • Repeat
  • Hot Wash at 90°C plane water
  • 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.
