Waterborne & Bio-Based technologies in textile
📌 Basic Definitions
1. Waterborne Technology
Waterborne systems use water as the primary solvent instead of organic solvents with high VOC (Volatile Organic Compounds).
In the textile industry, waterborne technology is widely applied in:
- Textile coatings
- Textile printing inks
- Fabric finishing
➡️ Main objective: low emissions, environmental safety, and worker-friendly processing
2. Bio-Based Materials
Bio-based materials are derived from renewable resources, such as:
- Plant-based feedstocks (corn, sugarcane, soy)
- Natural oils
- Biomass
In textiles, they are used as:
- Binders
- Resins
- Additives
- Softeners
➡️ Goal: reduce dependence on petrochemical-based materials
🧵 Role in the Textile Industry
Waterborne and bio-based technologies are key drivers of sustainable textile manufacturing, helping the industry transition toward greener processes.
