Archroma, a global supplier of specialty chemicals towards sustainable solutions, recently introduced the NTR Printing System to make bio-based pigment printing commercially possible for the first time. Based on renewable raw materials and designed for safer chemistry, it helps apparel and textile brands reduce their environmental footprint while producing brilliant black shades on garments that deliver both comfort and durability.
Bio-based pigment printing is an emerging technology that is attracting major interest from brands that want to use pigments derived from natural sources, such as plants, in the production of environmentally conscious textiles. Until now, however, bio-based pigments have not delivered color fastness that is comparable to synthetic pigments, and color quality and production performance have not been sufficient to support commercial-scale production.
Archroma’s NTR Printing System is the first to utilize renewable feedstock across pigment dispersion, binder and fixing agent. Crucially, it ensures good wet-rubbing and dry-rubbing fastness, with outstanding softness on all kinds of fabrics. Furthermore, it is suitable for most popular application technologies, including printing, coating and continuous pigment dyeing, with outstanding runnability for production efficiency.
The result of more than two years of research and development, the innovative new NTR Printing System required Archroma to create customized binding and fixing agents to ensure fastness for the pigment black dispersion comparable to current petroleum-based printing systems. All three printing elements are partially based on renewable feedstock to reduce reliance on non-renewable petrochemicals. Archroma also developed the new system to avoid toxic input streams and impurities, including formaldehyde. Two successful bulk trials were conducted with Textprint S. A. and Jeanologia.
