The two German specialty manufacturers, Märkische Faser and Kelheim Fibres have disclosed “Clean Color Concept”, in which the two renowned fiber producers offer spun-dyed fibers in polyester and viscose in a coordinated range of colors.
Spun-dyed fibers have always been an important part of the range of products both of Märkische Faser and Kelheim. Here, color pigments are incorporated in the spinning mass before the spinning process, and are therefore homogenously distributed in the whole fiber. These fibers, and the final product, offer a particularly high color and light fastness. The colors do not bleed during washing, and they keep their brilliance even after many washing cycles.
In contrast to conventional dyeing processes, the colors can be reproduced exactly. Besides, the usually lower production costs and shorter throughput time, this is one of the main advantages for the further processing chain.
The environment is however the main beneficiary of the “Clean Color Concept”: The addition of color directly into the spinning mass saves up to 50% of color pigments. Further chemicals, energy and above all an enormous amount of wastewater from conventional dyeing processes are completely omitted thanks to this technology.
Textiles made from a blend of spun-dyed polyester and viscose fibers combine the advantages of both fibers: They are easy-care and dimensionally stable yet feel pleasantly soft on the skin and offer high wearer comfort. They are ideally suited for all applications that need large quantities of fabrics of a precisely defined shade and that must deliver comfort and wear qualities as for example professional clothing or uniforms, but also furnishing or upholstery fabrics.
