How is superwash wool treated to become machine washable?

Answer by  Echo (229)

The wool is treated with a resin which coats the fiber and fuses the wool. The entire process includes a pretreatment, rinse, neutralization, rinse, and then the coating with the resin and last but not least, the addition of a softener

Superwash wool is treated in an acid bath that corrodes away the natural scales on wool. The scales on wool are what cause wool to felt; the scales interlock and snare creating felt. By removing the scales, you remove the chance of wool felting when washing.

Well basically it has a lot of chemicals on it that will prevent it from getting damaged if washed in a machine.

Sometimes the fibers are coated with a polymer, and other times it can be because the wool's been treated with an acid bath that helps keep the wool from shrinking.
