vat dye

Unlike other vat dyes which use oxygen to develop their color, Inkodyes are developed by light.

Cotton, wool, and other fibers can be all dyed with vat dyes.

The vat dyes have high color fastness, which is uncommon in other dye classes.

During her time in Paris, she pioneered the use of vat dyes and the screen print process for home fabrics.

Vat dyes characteristically require a reducing agent to solubilize them.

Vat dyes and acid dyes are used because of its favorable properties.

Not all vat dyeing is done with vat dyes.

Many vat dyes are derivatives of indigo dye.

Vat dyes are essentially insoluble in water and incapable of dyeing fibers directly.

On the other hand, vat dyes tend to have poor rubbing fastness, but this can be mitigated with special treatments to the fabric.

The most common example is in applying sulfur dyes and vat dyes; with indigo being a classic case.

The extra complexity and safety issues (particularly when using strong bases such as lye) restrict use of vat dyes in tie-dye to experts.

Vat dyes are insoluble in water in their unreduced form, and the vat dye must be chemically reduced before they can be used to color fabric.

Prints: The fabric is normally woven from plain cotton or a cotton rich mix yarn into a plain 'grey cloth' which is then printed using vat dyes or pigments.
