What ‘Superwash’ Means on a Wool Yarn Label

Wool fibers have microscopic scales that can lock together under moisture, heat and agitation. Superwash processing changes that behaviour to reduce felting.

What the label does—and does not—promise

“Superwash” means the wool has received a treatment intended to improve washability. It does not automatically mean every machine cycle, detergent or dryer setting is suitable.

Expect a different fabric response

Superwash yarn may relax or grow differently from untreated wool. The amount depends on the yarn construction and project. Wash the gauge swatch using the planned care method, let it dry fully and measure again.

Handle the finished item as labelled

If the band permits machine washing, use the specified setting. If tumble drying is not allowed, reshape and dry as directed. Keep the label or a photograph of it with your project notes.

When mixing superwash and non-superwash yarn, choose a care routine safe for the more delicate yarn and test the combination before making the full piece.
