Printing of cotton fabric with reactive dye

Theory: Now-a-days reactive dyes are very popular for textile coloration because of its some specific properties like colorfastness. Then textile printing is one kind of localized dyeing that is dyeing that its dyes are pigments are applied locally or discontinuously

to produce various design on the fabric with a motif in one wore color and thickness is thickness with imparts stickness and plastically to the print peast. So that it may be applied on the fabric surface without bleeding or spreading and be capable of maintaining the design out lines.

Recipe: Thickness preparation :

CMC ---------8 part

Water--------92 part

Total = 100 part

Temperature --- 70°C

Time ---------------10 min

Printing peast preparation:

Reactive dye ----------- 2 part

Na₂CO₃ ------------------ 3 part

Salt -----------------------4 part

Urea --------------------- 2 part

Glycerin ---------------2 part

Resist salt --------------5 part

Thickness ---------------70 part

Water -------------------- As required

• Printing
• Drying
• Steaming: Temperature = 100- 105°C
•                      Time = 1-5
• Washing with cold water
• Drying

Printing on Fabric with Natural Materials with Jane Davila: UV Reactive Dye Printing

Function of chemical required:

Glycine: It is one kind of hygroscopic agent. It is increasing the moisture absorption. It is increasing the moisture absorption from air.

Urea: It is one kind of hygroscopic agent. It is increasing the moisture absorption from air.

Resist salt: It is one kind of surface reducing agent which is used to prevent surface selection, so that dyes remain in the fabric surface.

Sample:

Sample is attached below:-

Fabric type: Cotton fabric

Dyes type: Reactive dye

Color: orange

Conclusion: Printing is an easy process to drying various colorants in fabric surface.
