About RotaSpray

DyStar and RotaSpray successfully developed their indigo spray dyeing procedure for production on a bulk level which allows denim producers to significantly reduce their environmental impact. The solution was first introduced at ITMA Milan in 2015. Since then, DyStar and RotaSpray have been working together to develop it further and make it available for bulk production in important Denim markets like Turkey, India, Pakistan and China.

The new Spray dyeing technology combines DyStar Indigo Vat 40% Solution and the effective optimization of spraying parameters of the EPO patented RotoDyer® and the RotoCoater® spraying technology. This technology is awarded with important ECO certificates and offers high flexibility for dyeing small lot sizes, reduced water usage and effluent discharge, a lower impact on yarn in the dyeing process and simplified recipe changes.

Vision
