Copenhagen, Denmark - November 4, 2014 - The adults nearly 20 years, bleached jeans safe and sustainable through the introduction of Novozymes DeniLite. With the technology of the enzyme instead of aggressive chemicals, a lightweight alternative solution is for the treatment of denim. The latest offering is a product of Novozymes cold, so cold bleaching DeniLite known.

Cold treatment, soft and fast
"As bleaching Our solution at low temperature, tap water," said Bill Ole Jorgensen, Director of Business Development for the textile division of Novozymes.

Bleaching of the new solution based on  enzymes called peroxides and innovations designed to operate without extra oxygen or water. This new peroxidase has a very fast response - 90% of the reaction was completed in 10 minutes.
The technology also offers stain resistance to cold tissue because of the conditions of gentle washing. Enzyme solutions are very specific, c. Only the indigo dye onto the harder material of opposite chemical bleaching, which means that the strength and elasticity of the fabric remains the same.

Enzymes mode used
These substances are often both dyed with indigo and sulfur dyes. Bleaching solution is too cold very effective when used with the indigo dye. Do not wash the pigments and sulfur black or brown only blue sulfur dyes slightly changed tone. This means that various shades of color may be implemented using various combinations of dyes, the fabric can be produced. Shades of cold finished materials can be very different from those of traditional chemicals.
