However, the way color is added to fibers can directly affect the sustainability of the final fabric, which is an important topic for the textile industry. Avient’s high performance colorants and additives support the textile industry as it seeks to increase the sustainability of its products and manufacturing processes. Additives that help enhance properties and improve fiber manufacturing processes can help fiber and filament producers meet the challenging performance and regulatory requirements of different textile applications.

Automotive textiles, for example, can be matched with molded polymers to create tactile interiors for aesthetic purposes. But beware: Matching colors on disparate materials, such as textiles and molded polymers, is not an easy task. Disparate colors: Mixing the colors of textiles in a car’s interior can stretch its appeal to new audiences.

Avient’s business objective is to use conflict free materials and components in our products and expects our global supply chain partners to do the same.
