By using less water as well as decreasing pollution in waterways, solution-dyed fiber production is more environmentally friendly than traditional bath dyeing methods. The BASF Colors & Effect GmbH, Ludwigshafen/Germany, offers a focused portfolio of colorants for solution-dyed fiber applications.
The colorant range meets performance requirements for various polymers as well as high purity standards by Oeko-Tex Association, Zurich/Switzerland.
By controlling potentially harmful chemicals even if they are not yet regulated, the Eco Passport by Oeko-Tex certification signals the highest product purity to the fiber industry. On the path to increasing sustainable fiber coloration, the shift to solution-dyed fiber production has long been highlighted by the industry as a resource-saving process in comparison to bath-dyed fiber production.
Additionally, the solution-dyed fiber process produces a more durable fiber with longer service life, prolonging the time a consumer keeps a product before replacing it.
