Separation of Polyamide 66 From Blends With Wool Through Selective Dissolution: Implications of the Presence of Dyes

Journal of Applied Polymer Science, Volume 143, Issue 33, September 5, 2026.
The study assesses dye impacts on PA66/wool recycling via selective PA66 dissolution in calcium chloride–ethanol–water and water reprecipitation. Acid dyes migrate into solvent, yielding color‐free, melt‐spinnable PA66 and reusable wool. Metal‐complex dyes remain, altering PA66 melt viscosity and requiring extraction or repurposing.

Study on Natural Color Extract and Synthetic Color in Food Preparation

INTERANTIONAL JOURNAL OF SCIENTIFIC RESEARCH IN ENGINEERING AND MANAGEMENT
Palash flowers are abundantly available in and around Vidarbha. These are wasted as their importance as colouring agent is not known. Synthetic colour is commonly used in food preparation and is known to have a harmful effect on health. So it was postulated to introduce colour of palash flowers in food preparation in comparison with synthetic colour ...
