What is Carbonization of Wool?
Carbonization is a type of scouring that employs a chemical bath. Chemicals include hydrochloric acid and in some cases sulfuric acid to remove dyes from recycled wool. If you've ever experienced itchy wool, carbonization is partly to blame. The carbonization shreds the tiny hair follicles on the wool strands, making them brittle and ragged. It also strips away all of the natural lanolin. The result is itchy wool.
At Holy Lamb Organics, we never use carbonized wool. Our mill processes wool by scouring it multiple times with hot water and a natural, biodegradable soap. The wool is also carded several times.Carding is a brushing process that loosens and releases any debris, dirt, or vegetable matter from the wool without stripping the fibers or removing the lanolin. Carding also shifts the wool fibers so they are running in the same direction. The end result is a beautifully smooth, all-natural wool batting with bounce and natural resilience.
