Clariant claims denim revolution

31/08/2010
Specialty chemicals provider Clariant has designed a new eco-efficient dyeing procedure for denim producers.

The company has said that the new solution,
Pad/Sizing-Ox, will give denim brand owners and retailers new opportunities to offer fashionable, high-quality jeans based on “the most sustainable, resource-saving production method to date”.

Visitors to the Munichfabricstart 2010 bluezone (August 31–September 2) will be the first to experience the new technology.

Pad/Sizing Ox means textile mills can use up to 92% less water and create practically no waste water. It also allows a 30% energy saving together with 63% waste cotton savings compared to conventional dyeing procedures.

The Advanced Denim production method allows eco-bleaching wash-down with ozone and peroxide avoiding the use, and consequently the presence in waste water, of harmful chemicals like hypochlorite or permanganate.

The Pad/Sizing Ox process is based on Clariant’s recently patented Arkofil DEN-FIX sizing agent innovation. In combination with its full range of Diresul RDT sulfur dyes, including its non-indigo based Diresul Indicolors RDT dyes, Advanced Denim offers improved fastness, better reproduction of tones and shades, and easy application for more precise results. “The dyes expand the market’s potential to achieve new and interesting colours, deeper and faster blues, amazing blacks and greys, finely-graded shades and special wash-down effects,” Clariant said.
