Marks & Spencer, Novozymes develop sustainable technology for textiles

BAGSVAERD, DENMARK: An enzymatic bioblasting process of Marks & Spencer keeps clothes looking newer for longer, and comes with the added benefit that the bioblasting enzymes do not negatively impact the environmental footprint of the production. The Stay NewTM technology fits perfectly with Marks & Spencer’s ambitions to become the most sustainable retailer on the high street by 2015.

Han Kuilderd, Customer Solutions Manager, Novozymes, has worked closely with Marks & Spencer on the development of Stay New technology. “By using enzymes in textile production Marks and Spencer could create higher quality garments in a more sustainable way. In the school wear market, where competition is fierce, this is crucial,” said Kuilderd.

Stay New technology uses Novozymes’ bioblasting enzymes to weaken and remove protruding fibre ends that stick up from the fabric. This keeps the surface smooth, reduces pilling and ensures consistent bright colours. And best of all, the process can combine both the bleach clean-up and dyeing stages, which significantly reduces energy and water consumption compared to a non-combined process. It can also save up to 90 minutes processing time when compared to running the processes before or after dyeing.

Novozymes enzymatic solutions are biodegradable, natural proteins that act as catalysts for biochemical and chemical reactions. They require only a very low dosage and do not contribute greatly to effluent loads.

The bioblasting process takes place at pH 5-7 and at the relatively low temperature of 50-60°. The combination of enzymes and mechanical abrasion from a washing or jet dyeing machine creates a permanent change to the fabric without the use of chemical coatings or the application of gases and fire.
