WLD P-type reactive dyes printing process

    The new environmental reactive dyes with new active groups;It has lower reaction, good fastness and alkaline stability, and the reaction conditions shall be strictly controlled.

1,  Printing process

1.1,Pre-treatment

The pre-treatment is necessary for fabrics before printing to ensure the best printing results, for woven fabrics or knitted fabrics, because the residues, addition agent and chemicals used in production shall be removed to avoid affecting the printing effect.

1.2,Mercerization

After mercerization, the dye yield, brightness and wet/dry fastness of printing can all be improved for woven fabrics or knitted fabrics.

1.3,Dye printing

When selecting the WORLD brand P-type reactive dyes in the dye printing, dyeing, using the soda as alkaline agent can achieve better effect, and the soda ash can also be used as alkaline agent.

2,One-phase printing process

Process flow:Fabric feeding →Printing →Drying →Steaming fixation →Washing→Soaping →Washing

→Drying

Fixation conditions

Steaming:102-103°C                  5-10min(cotton/adhered)

or Curing:150°C                      3-5min(cotton)

or high temperature steaming:175°C      6-8min(polyester/cotton)

or Curing method:190-200°C            1-2min(polyester/cotton)

2.1,Printing paste prescription

2.2,Post treatment of printing

1)Overflow cool water rinse

2)Cool wash

3)Hot wash70°C

4)Hot wash70°C

5)Hot wash 90-95°C adding 2g/l chelating dispersant

6)Hot wash 90-95°C adding 2g/l chelating dispersant or 2g/l nonionic soaping agent             

7)Hot wash70°C
