In a bid to boost sustainable denim production, California based Twin Dragon Marketing has announced the launch of ecological improvements in their Northern Hemisphere Mexican mills and at their Asian facilities, by introducing liquid indigo and eco-finishing. These eco-initiatives are the most advanced techniques in the current marketplace.
“Finally after three years of development, we are proud to introduce — pre-reduced liquid indigo and eco-finishing–which when used together, has achieved 85 per cent reduction in environmentally hazardous chemical discharge, which could become the new gold standard in the denim textile industry. With the implementation of liquid indigo and eco-finishing, not only have we eliminated tons of chemical and water usage compared to the current dyeing and finishing standards at the mill level but—it stabilised the shade of indigo, increased the colorfastness in both dry and wet crocking and the final denim product has a 3D appearance– it’s amazing! In addition, this new eco-denim will help the denim laundry house save water, minimise chemical usage and speed up garment processing – it’s the best scenario for both our mills and garment manufacturers,” said Dominic Poon, CEO of Twin Dragon Marketing.
Over the last 10 years, Twin Dragon has made significant investments in eco-friendly fibres, such as Lenzing’s Tencel and Modal, has developed their own trademarked Forever Black which eliminates the environmentally costly dye process for black jeans. The eco-denim collection coextends Twin Dragon’s dedication to development that positively affects the environment, especially the water eco-systems affected by the denim industry.
The use of eco-finishing at the Mexico mill for a whole year would save up to 40 mn gallons of water. Also by using liquid indigo, 700,000 lbs of sodium hydrosulphite would be saved from contaminating the environment in one year, a 57 per cent conservation compared to the current powder indigo standard.
