Both natural and manmade fibers can be dyed at this stage. It gives very uniform dyeing and fast colors. But there is a lot of wastage during further processing of fibers.

Fabric stage

This is the most popular stage of dyeing. Most of the fabrics which are dyed in a single solid color are dyed at this stage. This method is a fast method and it is easy to match colors. Blended fabrics can also be dyed.

Garment Dyeing

Sometimes, after stitching the garment, there is a need to dye it, for example, dupattas for suits are dyed after making.
