If you have ever held a skein that felt incredibly soft, almost silky – and promised to be machine washable – then you probably had Superwash yarn in your hands.
But what does that actually mean? And why do so many rave about non-Superwash wool when the other sounds so practical?

This article invites you to get to know both yarn worlds: the smooth, easy-care side of the Superwash treatment – and the natural, textured side of untreated fibers. Because which option you choose says a lot about your knitting feel, your values, and your favorite pieces.

What does “Superwash” mean?

“Superwash” refers to a process where wool fibers are treated so they can be machine washed without felting.
This happens in several steps – usually with chlorine treatment and a resin coating. The natural scale layer of the wool fiber is smoothed or coated in the process.

Result:

  • The wool feels smoother.

  • They often have a slight sheen.

  • They can be washed easily without shrinking.

  • Colors appear more intense and even.

Superwash yarns are especially popular for:

  • Baby and children's clothing

  • Everyday items that are washed often

  • Projects with clear, bright colors

And what is Non-Superwash?

Non-Superwash – also called “natural wool” – is pure, untreated wool. Its scale structure remains intact, and that is exactly what gives it character: warmth, texture, and a slightly “lively” feel.

These fibers feel more natural, breathe better, and offer high elasticity. They also have self-cleaning and temperature-regulating properties.

Non-Superwash yarns are ideal for:

  • traditional and rustic knitwear

  • Cable patterns and textured patterns (that hold up better)

  • natural, matte shades

  • conscious projects focusing on regionality and sustainability

A comparison – feel, behavior, care

Property Superwash Non-Superwash
Tactile feel Smooth, soft, slightly shiny Textured, warming, natural
Care Machine washable Hand wash recommended
Appearance Clear colors, even Lively surface, rather matte
Knitting texture Flowing, with more movement Stable, shape-retaining
Sustainability Chemical treatment necessary More environmentally friendly, untreated
Area of use Everyday clothing, children, socks Sweaters, cardigans, Fair Isle patterns


The knitting feel: perception with the hands

Anyone who has once had non-superwash yarn on the needles knows this little moment when the yarn almost responds. It catches slightly, is grippy – you consciously feel every stitch. The result is a fabric with character and depth.

Superwash, on the other hand, glides through the fingers like a silky-clear promise. Stitches flow, knitting goes quickly by hand. The knit falls softer, often more fluid – perfect for scarves, shawls, and delicate pieces.

Both can be incredibly satisfying. It depends on how you want to knit, not just what.

Topic Sustainability

Here the philosophy world of knitters diverges.
Superwash treatments mostly use chemical processes that make environmental aspects critical. Although there are now alternative methods – such as enzyme-based ones – very few are completely chemical-free.

Non-Superwash yarns, on the other hand, are often:

  • locally produced,

  • washed more gently,

  • and retain their natural properties.

Sustainable therefore means not only "eco" but "durably beautiful." A Non-Superwash jacket ages gracefully – it becomes softer, shapes itself to you, and over time tells your story.

Frequently Asked Questions (FAQ)

1. Can I really not wash Non-Superwash?

Yes – but carefully! Hand wash in lukewarm water with some wool detergent is completely sufficient. Important: do not rub or wring, otherwise the material felts.

2. Is Superwash worth it if I knit many everyday items?

Yes, absolutely. If you knit for children or everyday use, the easy-care option is often more practical.

3. Can I mix yarns?

You can – but make sure both yarns drape similarly. Superwash yarns often stretch more, Non-Superwash remains more stable.

4. How do I recognize if a yarn is Superwash?

This is usually on the label. Often you can also recognize it by the smoother surface and the gentle shine.

Conclusion: Which yarn suits you?

There is no "right" choice – only the one that suits you.
Superwash is comfortable, brilliant, and practical. Non-Superwash is honest, sensual, and durable.
Both types have their beauty.

If you like, try it out: knit two small swatches – the same needles, the same pattern. Feel how the stitches settle, how the yarn reacts to warmth, movement, and washing.

This is how you find out what makes you happy when knitting.
