From the Sector

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 and Pakistan. With the recent breakthrough, they are now announcing a salt-less dyeing solution for the denim industry. This new technology is awarded important ECO certificates and offers high flexibility for dyeing small lot sizes, reduced water usage and effluent discharge lower impact on yarn in the dyeing process and simplified recipe changes.

The new Spray dyeing technology combines DyStar Indigo Vat 40% Solution, Sera® Con C-RDA (a unique organic reducing agent) and the effective optimization of spraying parameters of the EPO patented RotoDyer® and the RotoCoater® spraying technology. 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 pressure and a global demand for more sustainable solutions were motivators for the R&D of the industry and led to the recent technology leap.

On sheet dyeing ranges (slasher), with process and layout modifications, coatings including DyStar Indigo Coat, Cassulfon®, Remazol®/Levafix® and Imperon® dyes can be applied by spray dyeing as well. The spray application of fixing agents and oxidation chemicals can be integrated into sheet dyeing (slasher) as well as rope dyeing machines.

As a combined effort of the CSI color team and DyStar’s technical experts, DyStar and CSI are launching the first 2 issues of the Sustainable Color and Trend magazine with Cadira® color palettes.

This new magazine inspires Designers and Color Managers by offering palettes and color combinations that are Eco-friendly and Inspired by Nature. Not only does the magazine include a wide range of color palettes, but also color validation in CSI’s Relative Color Popularity (RCP) information as well as sustainable dye recipes that have been formulated based on the Cadira resource optimization process.

The Cadira Concept is a module in DyStar’s Resource Efficiency program. It helps to considerably shorten lead times and reduce water, waste and energy consumption. Cadira Concepts have been developed for different substrates and dyeing procedures. This launch focuses on both reactive dyeing of cotton as well as polyester & recycled polyester dyeing.

The reactive-issue – Inspired by Nature – offers color palettes with softer, muted tones, levels of neutrals and earthy shades of green. The recipes are based on DyStar Levafix® and Remazol® combined with Sera® chemicals for an optimized dyeing and wash-off process.

The Polyester issue offers more vibrant color options with saturated colors and brights for active wear and outdoor clothing and accessories. The recipes are based on Dianix® dyes and the dyeing process can be optimized by use of the Optidye® PES program.

“We are conscious about our environment so we wanted to create a magazine with an ecological color and optimized processes so that our customers can pick the right color that will help them reduce their environmental impact in the design process.” Says Ron Pedemonte, VP of Sales and Marketing Americas.

CSI will fcus more on color palettes with ecological dyes and low impact processes when offering color and trend information to customers in the future. More eco-friendly color palettes will be available very soon.

More information about CSI color trends and the Cadira process is available in the DyStar Website and CSI Website. www.dystar.com / www.csicolors.com

SDC’s annual competition engages with hundreds of students, universities and designers globally, helping the entrants develop their understanding of color and the challenges around sustainability in the textile supply chain. The theme for 2018 is ‘color communication’.
With a global textile supply chain, being able to communicate a given color through the supply chain efficiently and effectively is vital. Ultimately this provides the designer with the knowledge that their product is commercially suitable from the initial concept stages through to final product.
Archroma will support the competition with its Color Atlas color management system, which will be key to both the competition theme and the accompanying educational package.
Using these colors also provides the best opportunity to minimize the environmental impact during the dyeing/printing process by ensuring that the dyes conform to many of the environmental standards that exist and are applied using best practice.
“We at Archroma are very proud to be the official sponsor of the SDC International Design Competition. The participants will be able to experience first-hand how the Color Atlas can support their creativity. For Archroma, this is a great opportunity to further drive innovation and sustainability in the textile supply chain“, commented Brad McClanahan, Global Head of Service Businesses at Archroma.

An exciting new development, resulting from a Swiss collaboration between textile manufacturer Schoeller and auxiliaries and dyes specialists at Textilcolor. ecodye is a new auxiliary concept used, in particular, in polyester dyeing processes. The technology accelerates the dyeing process and contributes to cutting costs, while at the same time helping to preserve the environment with a low level of demand on resources.
Less time, less water, less energy – the new ecodye auxiliary concept allows eco-friendly and cost-saving dyeing processes for polyester yarns and piece goods. It shortens the heating phase, thus accelerating process time by more than 30 percent. At the same time, it reduces energy consumption by 20 percent and the water requirement by 25 percent, as the goods can be cleaned in the cooling dye bath.
In addition, ecodye improves the dyeing levelness in polyester textiles. Spots and dye agglomeration are almost completely avoided, and the precipitation on the goods that arises as a result of polyester oligomers are no longer evident. ecodye provides good shade stability and avoids reproduction problems from batch to batch, thus reducing the rate of double staining and increasing the capacity utilization and productivity of the dyeing mill on a long-term basis.

Following a successful launch phase, ecodye has already been able to provide numerous positive test results. The technology is being used by polyester-processing customers in categories including outdoor, sportswear and technical knitted fabrics, primarily in Europe, South and Middle America, Turkey, Bangladesh and China.
