Carding is a peculiar way of processing fibers that cleans and parallelizes them in order to create a yarn with a more fuzzy, voluminous and warm appearance.

Chunky wool, also known as carded wool, is considered more sustainable than classic worsted wool, because some of the scrap generated by the machines used to comb the wool, is re-used in carding.

Chunky wool is a type of wool that undergoes the carding process, but afterwards it's not combed, so that it feels more raw to the touch, but thicker and softer. In fact, the carding stage brings the finest fibers to the surface and traps microscopic air bubbles inside the yarn, allowing it to stay warm for longer.

Worsted wool, on the other hand, is initially carded, but then undergoes the combing stage, which makes it lighter and fresher and becomes easily recognizable by its typical shaved appearance.

Unlike combing, carding involves the use of fibers of different lengths and which are not uniform. In fact, combing uses longer and more wavy fibers which generates more waste, whereas carding, on the other hand, combines the longer fibers, called tops, with the shorter fibers, called open, in such a way that they're tied together to make a better carding.
