Abstract
A process for preparing a natural fiber fabric for finishing the fabric with a botanical dye or printing content on the fabric with a botanical dye includes washing the natural fiber fabric in a washing solution comprising approximately equal parts washing soda and baking soda dissolved in water and rinsing the washed natural fiber fabric. The process also includes pre-treating the washed natural fiber fabric with a pre-treating solution comprising a bio enzyme in water and rinsing the pre-treated natural fiber fabric. After pre-treating, a pH of the washed and pre-treated the fabric load may be neutralized with a solution comprising vinegar in water.
