Natural Dyes TRIZ Cases
- Biocompatible and biodegradable natural disperse dyes for dyeing polyester fabrics
See how acid chlorophyllin derivatives form water-insoluble disperse dyes for polyester, achiev
- Biomass Sulfur Dyes for Low-Toxicity Textile and Paper Dyeing
Waste vegetal biomass is sulfurized into soluble dyes with good fastness, cutting toxicity, CO2 generation, and land-intensive dye crop use.
- Biomass-Derived Sulfur Dyes With Fastness and Lower Toxicity
Waste vegetal biomass is sulfurized into soluble dyes for textiles and paper, preserving color fastness while reducing toxicity and CO2 impact.
- Biomass-Derived Sulfur Dye Composition for Fast Color Dyeing
Pretreated waste biomass is sulfurized into aqueous dyes with strong fastness, reducing petroleum toxicity, sulfide content, and CO2 impact.
- Natural coloring agent composition
Plant nitrate reductase generates high nitrite with low free sugar, enabling meat color development without bacterial inoculation or browning.
- Core-Shell Colorant Particles for Stable Patterning in Liquids
Edible core-shell particles with a cationic polymer shell keep colorant in place, reducing leakage and enabling stable patterns in drinks.
- pH-Responsive Microencapsulation of Gardenia Yellow for Acid Stability
A pH-responsive polymer microcapsule slows gardenia yellow release in acid to prevent browning while preserving UV resistance and shelf life.
