AI Overview
Reactive dyestuff printing thickeners are specialized compounds—typically Sodium Alginate or synthetic polyacrylic acid—used to control the viscosity and flow of dye pastes on fabric, ensuring sharp, high-definition prints without bleeding. These thickeners enable high color yield and excellent wash-off properties, crucial for cellulosic textiles.
Key Types & Characteristics:
- Sodium Alginate: A natural, seaweed-derived polysaccharide favored for its superior washability and reliable performance.
Common Printing Applications:
- Screen Printing: Suitable for flat and rotary systems.
- Roller Printing: Provides consistent results for high-volume production.
Typical Print Paste Formula (Example):
- Thickener: 30-40 g (e.g., Polyacrylic acid).
- Reactive Dyes: 4-6 g.
- Urea: 10-14 g (acts as a moisture retaining agent).
- Anti-staining Salt S: 1-3 g.
- Water: Added to make 100 g total.

Why is sodium alginate thickener suitable in case of printing with reactive dye for cotton?
This is due to its better printing performance and minimum reactivity towards dyes due to the limited reaction between alginate and dye by mutual anion repulsion of the carboxyl groups, even if sodium alginate contains hydroxyl groups on the molecule.Feb 12, 2025
