AI Overview
Reactive dyes printing thickeners are specialized additives, primarily Sodium Alginate or specialized synthetic polymers, designed to control the viscosity and stability of printing pastes for cotton, rayon, and other cellulose fibers. They ensure sharp, non-bleeding designs, high color yield, and excellent washability by preventing the thickener from reacting with the dye.
Key Types of Reactive Dye Thickeners
- Sodium Alginate: The industry standard. It is a natural polysaccharide derived from seaweed that does not react with reactive dyes, ensuring soft fabric handles.
Key Benefits
- High Performance: Provides high color yield, sharp definition, and even, consistent prints.
- Compatibility: Designed for compatibility with reactive dyes and alkalis (soda ash) in the print paste.
- Excellent Washability: Ensures unfixed dye is easily washed off, preventing stiff handles.
- Versatility: Suitable for rotary, flat screen, and roller printing systems.
Usage Tips
- Paste Preparation: Synthetic thickeners often allow for faster preparation and higher stability compared to natural gums.
- Viscosity Control: The amount of thickener (e.g., 4-5% for specialized products) is adjusted to ensure the paste holds a clean line.
- Storage: Properly prepared pastes can be stored in the refrigerator, but it is often recommended to add fixatives like sodium carbonate just before printing.
