Yak, Mongolian, Churro and Zwartbles Fibers

Yak, Mongolian, Churro and Zwartbles Fibers

Our Guest Artist/Author today is Zara Tuulikki Rooke sharing her experience with some exotic fiber samples.

The Felting and Fiber Studio Forum is an excellent place to exchange ideas and experiences with other felters and fiber enthusiasts around the world. In addition, I have also done a couple of fiber swaps with other members on the forum. I have sent wool from our Swedish sheep breeds and have, in return, received a wonderful variety of fabrics and different types of wool and other fibers that can be used for felting. Now I have tried felting some of the exotic wool that I have received from Nada, Zed and Marilyn.

Nada, who lives in Slovenia, very kindly sent me Yak wool, which she got directly from nomads from Tibet. Apparently, Yaks have three different types of fibers; long and thick hairs forming the outer coat (79-90 microns), an intermediate type (20-50 microns), and a very fine and dense wooly undercoat (16-20 microns). The softness/fineness of the yak undercoat is comparable to the better known cashmere wool (which is a fine undercoat of goats). This particular carded batt also included some coarser fibers, but most of it was very fine wool. I laid out two thin layers of wool, on a 20 cm x 20 cm ( 7.87 x 7.87″) surface, put on a piece of cotton gauze, and attempted to felt it.

The Yak wool was surprisingly easy to felt. It quickly shrank down to a compact square of 10 cm x 10 cm (3.94 x 3.94″), and the fabric has felted in firmly. The coarser fibers give the felted piece a hairy appearance and reduce the softness, but I can imagine how luxurious pure, soft undercoat wool from Yak must be.

Zed, who lives in England, sent me some carded wool labeled “Mongolian.” A search on the Internet showed that there are quite a few local breeds of sheep in Mongolia, and crosses with imported breeds with finer wool. I found an article titled Sheep breeds of Mongolia describing 15 of their indigenous breeds of fat-tailed carpet-wool sheep. Our Swedish native breeds belong to the group Northern short-tailed sheep, while the sheep in the group fat-tailed sheep are adapted to harsh environmental conditions and are common in Africa and Asia.

I didn’t get any closer than that in the identification of the wool, but the carded wool feels like a mixture of coarse and slightly finer fibers, mostly black or dark brown (perhaps sun-bleached) with occasional white fibers. To be able to compare this to other wool, I chose the same method as I have used to make previous samples, i.e. 10 g of wool laid out in four thin layers to cover an area of 20 cm x 20 cm, and on top of it a piece of gauze. The wool was very easy to felt and full, and shrank to 12.5 cm x 12.5 cm (4.92 x 4.92″). Compared to Swedish wool, the felted piece feels similar to those I felted with wool from our landrace breeds Klövsjö and Åsen, although slightly rougher to the touch.

Marilyn, who lives in the US, sent me wool from the American breed Navajo-Churro. The breed has its origin in the Spanish breed Churra, which the Spaniards brought with them when they colonized, what is now, the southwest of USA. Navajo Indians got hold of the sheep and saw a value in the wool, from which they made carpets and other weaved textiles. The breed’s origins, near disappearance and subsequent rescue, and its significance for Navajo culture and textile crafts, is a really interesting read. More on that can be found at The Navajo-Churro Sheep Association and The Navajo Sheep Project.

The Navajo Sheep Project link:  http://navajosheepproject.com/churrohistory.html

The Navajo-Churro have a variety of colors, and three types of fibers. About 80% of the fleece consists of undercoat wool (10-35 microns), and the rest is coarser outer coat hairs (35+ microns) and less than 5% kemp (65+ microns). This wool was also easy to felt and full, although it didn’t shrink quite as much as the above. The final size was 15 cm x 15 cm  (5.9 x 5.9″), and it has quite a hairy appearance. In the photos below you can see the pure white kemp fibers that do not felt. But I like the rustic look and the different tones in the brown wool.

Zed also sent me some wool from Zwartbles sheep, which is a breed from the Netherlands, primarily used as meat and dairy sheep. The wool is black to sun-bleached brown, and the sheep have a white blaze on the face (hence the name “black” + “blaze”) and white socks on 2-4 legs. Pictures and more information about the breed can, for example, be found on The Zwartbles Sheep Association link.

The wool is described as medium to fine (around 27 microns), thick and springy with a good crimp, and popular for spinning and felting. The latter surprised me, because to me this wool personifies all the descriptions I have read about wool from meat breeds, which are generally considered difficult to felt. It is really spongy and bulky, without any shine, and even makes a slightly crunchy sound when you handle it. I would describe this wool as something that should be excellent to use as pillow stuffing. But maybe it works well for needle-felting, and I actually found some examples on the internet where people vowed that it was good for wet-felting. So, I had to give it a try. It was not easy to press the wool down and start the felting process with soap and water, but after a while, the fibers began latching into each other. Then I tried fulling, with a little rougher handling, and then it started to disintegrate completely. The very loosely felted and spongy piece is the same size as it was from the beginning, and I am astonished that piece keeps together at all. Different types of wool definitely have their different uses, and this would not be my first choice for wet-felting.

From Raw Fleece to Carded Batts of Wool

From Raw Fleece to Carded Batts of Wool

Our guest author/artist today is Zara Tuulikki Rooke.  She generously offered to take us through the process of preparing fibers from her own sheep to use for felting.

As I enjoy felting, I feel very fortunate to also be able to keep a couple of sheep. My four ewes are crossbreeds, from traditional Swedish breeds including the more well-known Gotland, and the perhaps internationally less well-known Rya and Finull. In any case, they do have really nice locks.

In Sweden, the common recommendation (with exceptions for certain breeds) is to shear the sheep both in the spring (to remove the thick winter fleece before they have their lambs and before the summer) and in the autumn (when they return to the barn and start spending more time indoors). The summer fleece (sheared in the autumn) is considered to be of higher quality. It has been grown while the sheep have been out grazing nutritious green grass, and not full of hay and straw like the winter fleece. Below is a photo of their summer fleece, sheared last autumn. The lighter, brown tips are from bleaching by the sun (and probably some dirt as they are unwashed).

Photo 2

My ram is from an old breed called Åsen. His fleece is straighter, without real locks. This breed can have a variety of fleece characteristics and different colours in patches on the same individual animal. My neighbour also has a ram of the same breed, and the darker fleece (black-brown-grey) on the photo below is from one of her lambs.

In addition, I also buy raw fleeces from pure Gotland sheep from a farm in a neighbouring village. The photo below shows some of the variation you can get between individuals, both in colour and in the size and shape of the locks. The lambs are born black, but later the wool turns grey and the once black tips are bleached by the sun. Or rather, they grown an increasing proportion of white hairs – there are no grey hairs, just different proportions of white or black hairs making the fleece look grey.

To a felter, this abundance of raw fleeces must seem like an ideal situation. And I certainly think it is. But, the process of turning raw fleece into carded wool is quite time-consuming. And that is what this post is really about.

After shearing, the fleece needs to be skirted and sorted, to take away wool that is too short, dirty or tangled. The short wool can either be from the head or legs of the sheep, or the result of what we call double-shearing (i.e. shearing a patch a second time to even it out). You usually also need to remove a fair amount of grass seeds and other vegetable matter that gets stuck in the fleece. That can take a lot of time, but it helps to do the sorting on some kind of wire mesh that allows small bits to fall through.

Then comes the washing. I try to get as much washing as I can done outdoors in the autumn, after shearing, up until the temperatures drop below freezing (in the North of Sweden that can be quite early in the season). I leave the wool to soak overnight in net-baskets in an old bathtub filled with cold water. The next day, the water will be really brown, but that just shows how much dirt you can actually clean out from a raw fleece with just cold water. I change the water at least twice after that, allowing the wool to soak for at least a few hours between changes, until the water no longer looks dirty. In my opinion, washing the wool in just cold water is sufficient if I am going to use the wool for wet-felting. During felting it will anyhow get washed again with hot water and soap.

During the winter, I do the washing in my bathtub indoors (which prevents anyone in the family taking a shower/bath for 24 hours), and then I usually use lukewarm water. If the wool is very dirty, I also add some washing powder (the type used for knitted wool items). The main rules when washing, to avoid felting the wool in the process, it to avoid too hot water, or quick changes in water temperature, and to disturb the wool as little as possible.

After washing comes drying. The net-baskets are easy to just lift out of the water and then I usually hang them up for a while to drip off a bit. If I am washing a smaller amount of wool, I often use one of those contraptions meant for spinning water from salad. Then I lay it out to dry, on a wire mesh or on towels on a clothes drying rack. Drying takes time, usually several days. It helps to turn the wool over each day and fluff it up a bit each time. It may seem dry on the surface, but wool has an incredible capacity for retaining moisture.
Finally, you have your washed and dried wool, ready for carding. However, some locks do need to be teased first. This means pulling apart the locks/fibres – and you will probably find even more grass seeds now. The photo shows washed locks, before and after teasing. It´s an extra step in the process, but if the locks are tangled in the tips, teasing really does facilitate the carding.

I own a drum-carder, which really does save time compared to using hand-carders. The wool is feed in under the small drum, which in turn feeds it onto the larger drum, as you turn the handle. After two or three runs through the drum-carder, you can finally lift off a batt of lovely, fluffy, carded wool. Then you can start felting!

Photo 7

It does take a lot of time and effort, and I do swear about grass seeds through the whole process, but each step also has its own charm. I often find it very relaxing to sort, tease and card wool. It provides an opportunity to really feel and look at the locks – and to plan what to do with them. And at the end of the day, when I look at my washed locks and carded batts of wool, I feel really wealthy. Perhaps, in part, because I know how much time and effort has been invested into those locks and batts of wool.

Thank you  Zara for such a wonderful tutorial with exceptional pictures to show us the whole  process from fleece to wool batts!
