Superwash Wool

Did you know that there is a type of machine washable wool? It's called superwash wool.

Properties

Normal wool fiber requires special care when washing, but superwash has been treated so that it will not felt or shrink. You can even machine wash it on the gentle cycle! It should still be air dried.

Production

This special type of wool does not grow on superwash sheep! It comes from the wool of regular sheep that has undergone the special treatment process.

There are two methods for treating the wool:

• Using an acid bath that removes the scales from the wool fiber
• Coating the fiber with a polymer that seals the scales

The coated type of fiber produces a wool yarn that feels more slippery on needles and hooks.
