The breakthrough dye synthesis technology creates natural shades from waste fleeces, solving a problem for sheep farmers and advancing sustainability for clothing and home textile brands


FiberColors® is based on the EarthColors® technology which is Archroma's patented method of synthesizing dyes to produce warm shades from nature.

A new method of creating warm shades from nature
FiberColors® is made from using wool waste as a raw material and is produced in the Castellbisbal plant (Spain). All brands and retailers will be able to create complete collections for casual wear, home textiles and denim garments.
FiberColors® is based on the technology of transforming wool waste into gorgeous upcycled colors. The colors are synthesized with a minimum content of 50% waste-based raw material, thus contributing to circular economy in fashion & textiles.
The FiberColors® range comprises of five dyes, covering a palette of natural shades: DIRESUL® Fiber-Teak (brown shades), DIRESUL® Fiber-Ochre (olive shades), DIRESUL® Fiber-Maroon (bordeaux shades), DIRESUL® Fiber-Slate (blue grey shades) & DIRESUL® Fiber-Graphite (dark grey shades)
The raw material and technology come with some limitations. That said, our R&D experts are continuously exploring other colors.
At present, we can use wool to transform waste into our FiberColors®. (Our R&D experts are continuously working in order to make FiberColors® by Archroma available from other fibers.)
At present, the FiberColors® range is available for wool, paper, and cellulosic fibers, such as cotton, viscose, linen, bamboo, kapok, etc. This means that partnering brands & retailers will be able to create complete collections including t-shirts, chinos, jeans, sweatshirts, hoodies, polo shirts, as well as home textiles.
Archroma uses its manufacturing facility, near Barcelona, with state-of-the-art dye synthesis equipment specially adapted to produce the FiberColors®.
Archroma is looking to partner with local suppliers who are located as close to our production facility as possible.
The FiberColors® range can be applied with most well-established dyeing processes, such as continuous piece dyeing, jet/overflow exhaust coloration, garment dyeing, as well as processes typically used in the denim coloration (slasher, rope…).
The FiberColors® can also be used in printing applications.
The FiberColors® have excellent affinity for wool, paper, and cellulosic fibers. Moreover, they have similar dyeing and fastness performance to conventional sulfur dyes.
Fibercolors® products are GOTS-approved, and we are awaiting bluesign, and ZDHC certifications.
Based on our experience with our EarthColors®, we are also quite optimistic that the FiberColors® would support obtaining high certification standards for the final article, such as cradle-to-cradle.
The FiberColors® technology is available worldwide.
