Comprehensive specifications and application methods for DYCROWASH Reactive Dyes

DYCROWASH

Introduction

Dycrowash dyes are high-performance reactive dyes formulated specifically for cotton and cellulosic fibre dyeing. They deliver outstanding wash fastness and excellent reproducibility, making them ideal for exhaust dyeing processes including jigger, winch, jet, and overflow machines.

The shades shown in the shade card were prepared on unmercerised cotton fabric. High dye yield and the best reproducibility can only be achieved by a process-controlled cooling and holding phase at 80°C.

  • Set the dyebath at 40°C with required amount of water and dye.
  • Levelling agent 1g/L
  • Run for 10 minutes and add anhydrous Glauber's Salt (B)
  • Enter the goods and run for 10 minutes.
  • Raise the temperature to boil within 30 to 45 minutes.
  • Add anhydrous Glauber's Salt (C) and continue the dyeing for 30 minutes.
  • Increase the temperature to 90°C within 10 minutes and continue the dyeing for 25 minutes.
  • Drain the dye bath at 70°C. Give two cold washes and dry.
  • If required, treatment of cationic dye fixing agent may be given to improve the fastness properties.

Note: High dye yield the best reproducibility can only be achieved by a process-controlled cooling & holding phase at 80 deg°C.

Shading: Cool to 70 deg°C add the shading dye, raise the temperature to 90 deg°C in 15 mins. & treat as usual.
