What Is The Optimal Temperature For Reducing The Aggregation Of Leuco Vat Dyes During The Dyeing Process, Specifically For A Sulfurized Vat Dye With A Molecular Weight Of 450 G/mol, In Order To Achieve A Uniform Shade And Minimize The Risk Of Unlevel Dyeing On A Cotton Fabric With A Twill Weave And A Yarn Count Of 30s?
The optimal temperature for dyeing cotton fabric with a sulfurized vat dye (molecular weight 450 g/mol) on a twill weave fabric with a yarn count of 30s is around 50°C, with a recommended range of 45°C to 55°C. This temperature range balances the stability of the leuco form, preventing aggregation and oxidation, while ensuring adequate penetration for a uniform shade.
