DyStar and BASF ink joint R&D agreement for improving dyeing of polyamide fibers

24-Dec-08
Germany's DyStar Textilfarben GmbH & Co. Deutschland KG and BASF SE have recently signed a cooperation agreement on joint research and development aimed at improving the dyeing of textile polyamide fibers. BASF is responsible for new polymers for fiber production while DyStar will see to the development of the dyes. Polyamide fibers on their own or blended with cotton have acquired ever-greater significance for fashionable and functional clothing in recent years, so that they have now become indispensable in modern fashion for sports and recreation. Aside from the standard grades, highly pigmented fibers and microfibers are being used more and more widely, the company says. Within its Ultramid® product line, BASF is developing new fiber polymers with improved dye absorption. This allows the use of dyes that achieve high levels of wet fastness and light fastness and that also have good fixation properties. With its Telon® RN dyes, DyStar has succeeded in developing a complete range of reactive dyes for polyamide including a three color combination with good compatibility that meet very high fastness requirements. The Telon RN dyes allow brilliant and deep shades of color. They lend themselves particularly well for high-end articles that require fastness at laundering temperatures of up to 95°C [203°F] and multiple wash cycles at high temperatures.
