Q2. Why VAT dyes have good wash fastness
VAT dyes have good wash fastness due to their insolubility in water and ability to form strong chemical bonds with the fabric.
VAT dyes are insoluble in water, which helps them adhere strongly to the fabric fibers.
They form chemical bonds with the fabric molecules, making them more resistant to washing.
The molecular structure of VAT dyes allows them to penetrate deep into the fabric, enhancing their wash fastness.
Examples of VAT dyes include Indigo, which is commonly used in d...read more

Q5. How to dye vat dyes
Vat dyes are dyed by reducing the dye to a soluble form, then oxidizing it to insoluble form inside the fabric.
Prepare a reducing agent solution to reduce the vat dye to a soluble form.
Immerse the fabric in the reducing agent solution and let it soak for a specific time.
Remove the fabric and expose it to air, which oxidizes the dye and turns it insoluble inside the fabric.
Repeat the process if deeper color is desired.
Wash and rinse the fabric thoroughly to remove excess dye.
