DyStar and RotaSpray have jointly developed an indigo spray dyeing procedure, which allows denim producers to significantly reduce their environmental impact. The new technology offers high flexibility for dyeing small lot sizes, reduced water use and effluent discharge, lower impact on yarn in the dyeing process and simplified recipe changes.
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 and Pakistan. Although rotary atomizers have been established for several decades in the textile industry they were mainly used for rewetting textiles with moisture. But recent cost pressures and a global demand for more sustainable solutions were motivators for R&D and led to the recent technology leap.
RotaSpray, founded in 2013, manufactures rotating atomizers for tailor-made conceptions in dyeing and finishing of warp yarn, fabric and nonwoven as well. DyStar is a leading dyestuff and chemical manufacturer and solution provider, offering customers across the globe a broad portfolio of colorants, specialty chemicals, and services. DyStar also caters to multiple sectors including the paints, coatings, paper and packaging industries. Its expansion into the food and beverages and personal care sectors reinforces the company’s position as a specialty chemical manufacturer.
