Beautiful and unique wool colors without dyes and chemicals
Traditional chemical dyeing processes for wool guarantee an infinite chromatic variety and an easy reproducibility, but they have a significant impact on the environment, especially in terms of water consumption, power usage and chemical pollution. However, this is valid just for virgin wool fabrics, since when it comes to recycled wool fabrics, there’s a fascinating and sustainable way to create colors. Here at Manteco, we call it Recype® – the art of creating wool colors with no dyes and chemicals.
Obtaining colorful fibers from pre- and post-consumer garments
As explained here, after a meticulous cleaning and sorting process, pre and post consumer wool garments are divided by color and mechanically shredded to obtain a ‘new’ recycled wool fiber, all of this without using chemicals, but just with a little water. Also, no additional dyes are needed, because garments and scraps come already colored from their former life. For example, here below you can see a bale of knits that were divided by color (in this case yellow), which – after being shredded – have given life to a yellow recycled wool fiber.
The recycled wool warehouse as a painter's palette
Considering that millions of knits, garments and scraps are mechanically shredded every year, recycled wool warehouses are like a huge color archives. They’re filled with hundreds of bales, each one with recycled wool fibers of different colors and tones. Raw material artisans, also called Feltrinisti, draw from these bales just as painter does from his colorboard.
The creation of a 'color recipe'
When brands or designers forward a specific color request for a recycled wool fabric or jersey, the process of creating a new color starts. Raw materials artisans check what they have in the warehouse and choose different recycled colors and mix them in specific percentages, creating an actual ‘color recipe’ on a small scale. This process is a real form of art that no school can teach, but just experience.
Carding the 'color recipe' to make a trial felt
The ‘color recipe’ is carded with a traditional machine ( called Cardina ) to clean, mix and parallelize the fibers, ending up creating a trial felt ( or Feltrino ), a recycled wool puff that shows the new color obtained, with no dyes and chemicals.
Checking if the trial felt's color matches the requested color
Raw material artisans then compare the requested color with the one achieved through the ‘color recipe’ carding. If colors do not match, artisans repeat the whole process until the trial felt’s color perfectly matches the requested color.
A new recycled wool color is born
Once the trial felt’s color is approved, the ‘color recipe’ is archived and officially becomes a new recycled wool color. The latters are usually multiplied by the kgs of yarns that must be produced and prepared to be sent to the spinning mill, where it will be carded, spinned and twisted to produce ‘new’ recycled wool yarns.
