Terminology: What’s the difference between worsted & woolen wool fabrics?

If you have ever gone shopping for wool fabrics you may have seen some of the fabric described as worsted, and some of it  described as woolen.

If you are me, you may have wondered what this meant.  Aren’t all wool fabrics woolen?  I mean, they are wool, right?

Not quite!

In brief, worsted and woolen are  different types of wool (long staple  vs short staple), prepared in different ways, resulting in a different look and feel.  Under magnification, worsted yarns look smooth with long fibres, and woolen yarns are much hairier, with lots of short fibres and more pokey-out bits.  Worsted wools are slick when woven, woolen wools are knitted, crocheted, or woven into softer, fluffier fabric, or fulled fabric.  Worsted wools are better at keeping out the wind and rain, but woolen wools are warmer, because they are full of air which acts as insulation.

Worsted is also used to describe a particular way of spinning yarn, or weight of yarn, but I’m not going to go into that because it’s a modern spinning thing, not a historical textile thing.

Worsted wool comes from sheep with really long wool (long-staple): generally sheep that live in fairly easily accessible, lush, green pastures, as opposed to sheep that do best in harsher environments. The long wool from worsted-type sheep is arranged, either by gilling (pulling through holes) combing with metal combs, or as part of the spinning process, so that the fibres lie parallel and end to end: these long, parallel wool fibres are what characterise worsted wool processing.

Because worsted wool is made from long fibres which all lie parallel, the natural crimp of the wool is removed, and the forms a very tight, hard yarn when spun, with little space between the fibres (as opposed to the more open, fluffy woollen yarn).  When woven into fabric, worsted fabric has a tighter, harder, shiny-er finish, and can make a finer, lighter weight fabric.

The development of worsted wool fabric (in the modern sense) dates back to the Middle Ages, when changing agricultural practices in England meant that new breeds of sheep that thrived on rich, enclosed pastures were being introduced, at the expense of older breeds, which did better in rougher environments.  At the same time waves of Flemish weavers, fleeing unrest in the Low Countries in the early 14th century, immigrated to Norfolk in England in response to invitations to settle in England offered in 1271 to fullers, dyers and weavers. They  set up weaving in and around Worstead, in Norfolk, and introduced new spinning and weaving techniques.  The type of cloth they produced came to be known as worsted.

Worsted cloth was known in the 18th and through the 19th century  as stuff to differentiate it from cloth, which was woollen fabric.  Stuff was also used to describe other woven fabrics of fibres other than silk, especially once cotton became more common as a fabric in the late 18th century, so a mention of a garment made of stuff does not necessarily mean the item was made of wool, simply that if it was, it wasn’t woollen.

Worsted wool fabric tends to be more expensive than the same weight and quality of woollen fabric, because the pasture land needed for worsted sheep varieties is in higher demand (in New Zealand, for example, it is far more financially beneficial  for farmers to use pasture land for dairy cows than wool sheep), and because worsted fabrics require more processing.  However, you also get more wear for your dollar: worsted fabrics are also more durable than their woollen counterparts.  Desirable light or ‘tropical’ weight wools are generally worsted as well.

The one drawback, wear-wise, to some worsted fabrics is that they may go shiny at areas that receive a lot of wear, such as the seat of pants and skirts, as the parallel fibres are pressed more firmly together.  Twill weaves are more likely to go shiny than plain weaves.

There is also a semi-worsted type of fabric, with yarns that are spun tightly, but not combed.  This is a cheaper process, and is usually done with inferior wool to further cut costs.  Even with 100% wool fabrics there can be huge differences in quality and durability, which is why I prefer to buy fabric, and wool in particular, in person rather than online, unless it is from a very reputable supplier.

Today, worsted fabrics are most likely to be seen in men’s suiting, and in trench coats and other outerwear.

Woolen wool  usually comes from sheep with shorter wool fibres, though the shorter fibres (under 8cm/3″ or so) of long-staple sheep varieties that are combed out in the worsting process can also be used to make woollen cloth.

To make all the short bits of woollen wool lie nicely together so that it  can be spun into yarn, it is carded, or brushed in two directions at once with stiff brushes.  The name carding comes from the Latin carduus  or  teasel, because carding was originally said to have been done with teasel heads (note, the use of actual teasels for the initial carding is under some debate).

Once it is carded, the wool is spun, and then woven.  After weaving, woolen cloth is sometimes subjected to the fulling process (also known as waulking or tucking), which cleans the fabric, making it thicker, and works the hairs of the wool together, creating a uniform, almost felted surface, without much visible weave.  Fulling basically involves pounding  or rubbing the surface of the cloth, either with hands, feet, or clubs, or in special water-driven fulling mills, which began appearing in England in the early Middle Ages.

The first part of the fulling  process is scouring, when cleaning agents were pounded in to the fabric.  These agents were initially urine (the Romans used it), which is full of ammonia, which softened and whitened the wool, and later fullers earth, clay with mineral elements which performed the same purpose of softening, whitening, and absorbing oil and dirt.  Fullers earth is sometimes known as bleaching clay.

Once the wool was scoured, it would be rinsed (thoroughly!), and then beaten again, to matt the fibres together and thicken the cloth, making it more water and wind resistant.

Woolen cloth can also be brushed with teasels or carding combs after it is woven, to raise the nap of a  fulled surface.  This too was done with teasel heads: in fact, there are still some wool processing plants that still use teasel heads set on to a special frame for the initial or  post-wearing carding.  There is at least one teasel-head carding frame still in use in  a commercial factory  in New Zealand – which I think is pretty awesome.

When woven up, woolen cloth  is usually softer and fluffier than worsted stuff, though it can also be pricklier and hairier, if made with cheaper wool.  It’s generally easier to fit and sew with, because it  isn’t as slippery and stiff as worsted, and woolen cloth gives and eases around your body more.  However, certain woollen weaves are  prone to snagging, and may sag at the knees and bottom, or wear out at the knees.

Have a piece of fabric and want to know if it is worsted or woolen? If it is soft and fluffy, or has a brushed, fulled surface that looks almost like felt and makes it hard to see the weave, it’s woollen. If it has a smooth, slick, hard surface, it’s worsted.

Worsted fabrics generally look best for suits, and other smart, crisp, tailored garments.  Woolens are softer looking and drape better, so work better for more informal garments.

Common modern & historical woolen fabrics include:

  • Boiled wool – woolen fabric, woven or knit, which has been thickened or shrunk by heavy fulling and/or boiling.  You can create your own boiled wool by washing your fabrics multiple times on the hottest, roughest setting – assume that you will loose approximately 20cm of length for every metre.
  • Boucle – fabrics of wool or other fibres with twisted, irregular crepe threads and a loopy, textured weave.
  • Camelet – medium quality woolen fabric produced in England in the Middle Ages.
  • Camelin – luxury woolen cloth made from the wool of the angora goat, imported into England from the Near East in the Middle Ages.
  • Challis – soft, draping, lightweight, plain weave fabric of wool, cotton, or rayon.
  • Crepe – soft, draping fabric with a twisted thread, giving it a slightly nubbly surface and excellent drape, recovery, and movement around the body.  Wool crepes can range from very lightweight, to heavy double-weave crepes.
  • Knits (jersey, doubleknit, etc)
  • Tweeds – woolen cloth with an unfulled surface, often with mixed (heathered) yarns.

Common modern & historical worsted fabrics include:

  • Barathea – very fine twill weave fabric, mainly used for mens dress suits.
  • Bombazine – a twilled or corded fabric with a silk warp and worsted weft (now sometimes all silk, or made of other fibres).
  • Cavalry Twill –  a fabric with a steeply  diagonal twill weave, and a distinctive raised ‘cord’ or rib.  Also known as artillery tweed.
  • Gabardine – A very tightly woven fabric with a fine steeply diagonal warp faced (has a clear wrong and right sides) twill weave, invented in 1879 by Thomas Burberry, originally as a kind of waterproof fabrics, but used as a general term for the weave and fabric type by the early 20th century.  The name is taken from ‘gaberdine’, a word for cloak or raincoat dating back to the late Middle Ages.
  • Serge – Very tight, hard wearing twill weave, frequently used for suiting, but prone to shining.
  • Sharkskin – lightweight wool fabric with a fine, nubbly weave that is supposed to imitate the skin of a shark.
  • Whipcord – like cavalry twill, a fabric with a steeply  diagonal twill, and a raised ‘cord’ or rib.  There is no official difference between whipcord and cavalry twill (except that whipcord may also be made of cotton), so either term may be used to describe certain fabrics.

  1. Fascinating! I had never really given much thought to the origen of fabric names but there’s so much in them, thank you!

  2. Ooh! A topic close to my heart!

    I fear you may have become a little muddled on the worsted/woolen distinction of the medieval period and earlier, though. Cards do not seem to have been invented prior to the mid-14th Century (at least in Europe). Certainly, Roman and Anglo-Saxon wool processing appears to have been done solely with combs – although with shorter-toothed combs used in-hand and sometimes singly, rather than the longer-toothed, larger combs that were introduced from about 1300 and used in pairs, often with one mounted and often (as in your image) heated and greased.

    Thus, I suspect the pre-1300 Europeans were making wool fabrics that were worsted or perhaps, as you’ve defined it, semi-worsted (though with comparatively inferior fibres compared to the later fabrics). A survey of archaeological textiles would be needed to prove this, but pre-1300 is a bit out of my area of interest.

    Also, despite many claims, I’ve never found any actual evidence that cards made from teasels were ever used for fibre processing (indeed, experimental archaeology suggests it just wouldn’t work). I suspect it is a modern misunderstanding based on the fact that both the fulling tool and the fibre-processing tool are both called a ‘card’.

    Finally, a historical textile term you may want to add to your glossary is vaðmál. It is characteristic of the medieval Greenland finds and is a weft-faced 2/2 twill made from double-coated sheep, with the warp made from the coarse, long, hair-like outer coat and the weft made from the soft, fluffy wool-like under coat. It is woven on a warp-weighted loom and weft-faced due to being beaten until the threadcount of the weft is much, much higher than of the warp. It was also used throughout Scandinavia, often as a currency: http://en.wikipedia.org/wiki/Wadmal

    Oh, P.S. The way you’ve phrased this makes it sound like merino is one of the latter sort of sheep, when actually it’s one of the former: “generally sheep that live in fairly easily accessible, lush, green pastures, as opposed to sheep that do best in harsher environments (like merino).”

    • Thanks Panth! The pre-medieval discussion was something that I knew was a weak point in the research, as all my sources disagreed with each other, or simply didn’t discuss it, and it’s certainly not my area of expertise. There was extensive discussion of fulling in Roman times, which is generally associated with woolens, and the only sources that claimed pre-medieval fabrics were worsted were either extremely old (19th century), or relying on that same very outdated research. A number of the bog mummy garments also show slight fulling (though some scholars have surmised that it is a result of wear and the preservation, not an original fabric treatment), which indicates a more woolen garment. I suspect the most accurate thing to say would be that, between the differences in processing and the advancement of modern wool, many pre-Medieval wool fabrics do not fall nicely into either the worsted or woolen category.

      I’ve read the research disputing that teasels were every used for original carding, but I also once worked for a museum that had the notes from a late 19th century curator traveling in South America coming across rural villagers ‘using the heads of teasels to comb out the loose wool.’ The curator had brought back some teasels for the collection, but sadly, they were long since disintegrated. A kernel of truth to the teasel story? It’s certainly repeated in many reputable sources, so between the two I chose to include it.

      The nice thing about the internet (as opposed to print), is that you can update and correct and discuss things! I’ve been working on this article for months, and reading more and more sources which just contradicted each other, so I decided to just publish, and we can work things out from here! I’ve edited and clarified slightly based on your excellent comments.

      • Thanks for the reply! I’m certainly very much still learning, so it’s nice to talk things over. ^_^ (Also, I fear my knowledge, or certainly strong knowledge, is very, very much restricted to 14th C Western Europe…)

        I wonder if the evolution of the wool comb from the shorter-tined ones to the longer-tined ones mark its evolution into a more long-staple-wool-only tool and helped foster the development of cards…

        Re. fabrics, I totally agree with this: “between the differences in processing and the advancement of modern wool, many pre-Medieval wool fabrics do not fall nicely into either the worsted or woolen category.” Certainly, I’m not arguing that all medieval and pre-medieval wools were worsteds as we know them now. But they weren’t necessarily the fulled-and-fluffy sort of woolen either. (Actually, fulled wools came into vogue in the 14th C and at least in the previous centuries fulling was not fashionable, I believe. Hence also why patterned twill wools become less common in the 14th C archaeological record.)

        (Oh, another thing — many fabrics were sheared after fulling. You could even re-full and re-shear them to refurbish the finish.)

    Thanks for this – lovely explanation. Have to ask. – who is still using teasels?

  4. Your timing with this post is unbelievably amazing! I have a two yard piece of worsted wool that I got for a song BUT don’t have a project for as of yet. I was trying to find information on where it would have been used historically but kept coming up with “cloth” in my research, which I know is woolen not worsted. On the search for “stuff” now!

  5. HannahS says

    So interesting! I just shelled out for some real wool for knitting, and was wondering why the one advertised as having long fibres was smoother, softer, and warmer. Thanks for writing! I always look forward to your posts.

      If anyone wants to know the first one is Norman Kennedy a renowned fiber artist and bard.

  6. Elise says

    I have a soft spot for wool, and was very glad to see an entire post on the subject. And thank you, Panth, for a great discussion. Who else would like to sip on tea and listen to Panth and our Dreamstress discuss wool? Maybe have some samples or pictures to pass around at each example?

  7. You’ve found great historical images of the process, which I particularly enjoyed in addition to your text. Thanks for spelling out the differences!


  8. What really gets my goat is when land suitable for sheep is instead used for dairy cows. This requires huge amounts of irrigation which is bad for local waterways (and the run-off isn’t that great either). Bring back the sheep!

    • But wool prices are so low that farmers can end up paying the shearers more to simply sheer the sheep than they will make from selling it. Few people can afford to farm sheep for the fun of it, so farmers switch to dairy cows because they can make a living in NZ off of dairy, wool, not necessarily. Until we can change that, more and more farmers will switch to dairy, with all the negative environmental implications that has.

  9. Wonderful, wonderful, wonderful. Thank you.
    Posts like this always make me wonder what the distinctions are in Czech terminology. I really should start checking out Czech sources more… In this particular case, I guess the mostly historical term “sukno” has a lot to do with Woolen (not the least because teasel is called “Å¡tÄ›tka soukenická”) – but at the same time, I’m not entirely sure if it’s one-on-one, because it often isn’t. And the confusing part is that “soukat” the verb actually means, in its primary meaning, “to wind thread on a spool”…
    … I am definitely a bit of a linguist, perhaps a predominantly practical one, which is why I really, truly love your terminology posts.

    Thank you for this well written and informative post. I just wanted to know what worsted wool was, but I have ended up learning so much more. Thank you thank you

  11. Curry Powder says

    Thank you so much for this article. I am learning to sew and I was searching for information on wool for a rain coat. This really explainef it all. Now I know how to treat wool fabric to get the fabric the way I want it. I know how to treat denim until I get the feel I want. The information on boiling the fabric wzs perfect. Also all the comments were also helpful. Thanks.

  12. Lorij says

    Very interesting information. Thank you. Can worsted wool be washed would shrinking?

  13. Bill Villers says

    Excellent article and full explanation of worsted wools. I’m glad I googled my curiosity.

    I LOVED reading this! So interesting, and informative! Thanks for sharing.
