DyStar offers green option on polyester dyes
11/08/2009
Specialist chemical manufacturer DyStar has announced that a new disperse dye selection under its econfidence programme offers options for dyeing recycled polyester that “avoid chemical contamination issues” and is ideal for meeting retailers’ restricted substance list (RSL) and ecolabel requirements.
“Ecological issues are becoming increasingly important for retailers and consumers, as well as for textile manufacturers,” the company said in a statement.
The econfidence programme is an initiative the company has launched with a view to controlling the chemical and environmental impact of products supplied to the textile industry, and to building supply chain partnerships for more sustainable textile production. As part of the programme, it regularly analyses for chemical contamination the raw materials it uses in the manufacture of its own products. Disperse dyes are often multi-component mixtures and are one of the most critical of dyestuff classes with respect to chemical contamination.
“DyStar has evaluated nearly 200 critical chemical components in its disperse dyes,” explained Dr John Easton, the company’s global ecology solutions manager, “and of these, half are subject to regulatory control or retailer and ecolabel restrictions. We have a rigorous testing and compliance programme in place to ensure that our customers can meet these limits.”
The company has identified a range of Dianix disperse dyes that it says will meet the specifications of leading brands and retailers’ restricted substance lists and ecolabels. Steve Barron, its vice-president of strategic market, commented: “We believe this green range of Dianix dyes will provide a simple solution for dyers and printers who are struggling to meet the complex requirements of different RSLs.”
Dystar added that this green range of Dianix dyes is also suitable for use on recycled polyester fibres.
