COMPOSITIONS AND METHODS FOR DYING NATURAL FIBERS WITH NATURAL DYES TO ENSURE COLOR (HUE AND SHADE)-MATCH CONSISTENCY

摘要

This invention discloses novel and nonobvious compositions and methods suitable for the dyeing of natural fibers with natural dyes that ensure shade-match consistency. The present invention provides compositions and methods for the dyeing of natural fibers (yarns, fabrics and garments) with natural dyes while providing for uniform hue and shade-match in the same batch and between batches. It is believed that the use of ferrous sulfate solution at the disclosed concentrations and processes, together with the use of loosely wound yarn packages provides for enhanced dye penetration (take-up) by the yam package enabling uniform package dyeing.
