Solution dyed fabrics perform better than any other type of outdoor fabrics.

Discover here the coloring methods. Learn outdoor fabrics weaknesses and strenghnesses depending on the coloring process. Why solution dyed fabrics are the most resistant to UV rays?

  • Solution dyed fiber: Color process happens at the earliest stage by inserting pigments in the fiber core of a still melted raw material. Thus, color is an intrinsic part of the yarn that covers its full cross section and the yarn appears uniformly colored. Look at the carrot on the illustration below. This is the most appropriate coloring system for outdoor fabrics provided pigments are good. If so, color fastness to light is the highest, above 7 (on a scale of 8, UNE-ISO 105-B02:2014)
  • Dyed fiber or yarn dyed: it consists of applying color on uncolored yarn or fiber called “greige good”. The core of the yarns do not contain pigment. Pigment remains on the the surface of the section resulting in a lower light fastness that reaches a maximum of 6 (on a scale of 8, UNE-ISO 105-B02:2014). Look at the radish on the illustration below.
  • Fabric dyed or piece dyed: it is very similar to the above “Yarn dyed” but manufacturers apply color on a uncolored fabric after the weaving process. Again, light fastness reaches a maximum of 5-6 and even lower (on a scale of 8, UNE-ISO 105-B02:2014).

The drawing below illustrates what yarns or fibers look like depending on the coloring method:
