Genencor, a division of Danisco A/S, introduced PrimaGreen EcoLight 1, the latest in the company's portfolio of products for more sustainable denim bleaching. The PrimaGreen portfolio gives textile manufacturers the tools to produce denim apparel in a variety of finishes. In addition, with PrimaGreen, denim can be stonewashed and bleached using a single bath, requiring significantly less water and energy than the established process.
Traditionally, in order to create a vintage-style look, denim is treated with hypochlorite using significant amounts of water and energy. PrimaGreen EcoLight 1 is a liquid esterase enzyme that can be used to achieve the same look, but is biodegradable and made with renewable resources. In addition, when denim is treated with a combination of PrimaGreen EcoLight 1 and PrimaGreen Super, a cellulase enzyme, the vintage-style look can be achieved while cutting water by more than 50 percent and energy usage by more than 40 percent.
Similarly, treating denim with a combination of PrimaGreen EcoFade LT100, a laccase enzyme, and PrimaGreen Super creates an “aged” look while cutting water by more than 60 percent and energy usage by more than 70 percent. In addition, the use of PrimaGreen EcoLight and PrimaGreen EcoFade enables processors to change the garment cast and bleach sulphur-dyed denim.
“Today, textile manufacturers and consumers are looking for more environmentally friendly fashions without sacrificing style or quality,” said Glenn Nedwin, executive vice president of Genencor's Technical Enzyme Business Unit. “The PrimaGreen portfolio of products provides the tools to create just that kind of apparel.”
