Not all fiber is wool part II Fiber Quality

This is probably where I am least familiar on wool, especially how to judge and rate quality. There are full time jobs of people doing noting but rating and grading wool. So, with that being said, much of my information is going to come from external sources and added references.

Some animals have a single coat, some dual an inner and outer layer. In some cases you use the inner layer, in some the outer, and depending on the animal it may be difficult to separate the inner and outer layers. Hair sheep are not shorn but their fiber naturally falls out for summer. That isn’t to say it cant be used, but it doesn’t exhibit much if any of the qualities in fiber production.

Use this glossary of terms if there is a term you are not familiar with and it already doesn’t have a link.

Fiber is graded by many qualities, and depending on the final use and some may be more in demand than others. Use is a whole different topic which we will cover in Part Four. The main ways fiber is graded is by length, staple, crimp, fiber diameter,  color, cleanliness, and yield. I will try to explain the best I can each.

Here are some ideas on sheep and fiber from Sheep 101. We have several of the breeds listed, check out our animals sheep page.

Cleanliness is an important part especially for shearing. VM or vegetable matter is all the things that can get tangled into the fiber. Sticks, leaves, twigs, grains, etc. For the longest time when hearing people talk I always thought they were saying BM. When having kids in daycare the daily sheets would record bowl movements, BM, so I assumed they were talking about bowl matter i.e. how much poop is in the fiber. This is just grouped into the VM, as well as urine, sweat etc. A better term would be to call it Foreign Organic Materials as this would cover all the bases, and leave fiber and lanolin in tact for discussion. Having a variety of animals (see Our animals) we have come to appreciate low foreign organic material in the fiber. It is easier to shear, easier to clean, and takes a whole lot less time to process. We find all kinds of things from thorn bushes, to leaves, we have even found sprouting grains in the fiber where a sheep had feed grain on her back, it rained, then it started to sprout. Usually the other sheep smell the grains and pick it out like a walking lunch plate. To minimize foreign organic materials you can coat your animals. Yes, they wear a lightweight coat as long as the fiber is growing, and take at least three coats a season. Different animals have different lanolin content. Lanolin is an oil the animals produce, similar to oil in a persons hair. Some people have oily hair, some very dry, and it impacts the condition or quality of hair.  Using wool without cleaning the lanolin is called greasy wool, or wool in the grease. We will talk more about cleaning the fiber in Part Three about processing

The chart below came from Wikipedia

Common Name Part of Sheep Style of Wool
Fine Shoulder Fine uniform and very dense
Near Sides Fine uniform and strong
Downrights Neck Short and irregular, lower quality
Choice Back Shorter staple, open and less strong
Abb Haunches Longer, stronger large staples
Seconds Belly Short, tender, Matted and dirty
Top-not Head Stiff, very coarse, rough and kempy
Brokes Forelegs Short irregular and faulty
Cowtail Hindlegs Very strong, coarse and hairy
Britch Tail Very coarse, kempy and dirty

Length of the fiber is another part which may or may not be determined by the fiber grower (plant/animal). If it is an animal the shearer has a lot to do with the length of fiber, probably as much as the animal itself. On our first couple of sheep we sheared, we were so scared to cut the animal we left quite a bit of fiber on the animal making the usable fiber shorter. As we got more confident and experienced we were able to shear closer and closer without any injuries to the animals. Generally the longer the length of fiber the better. That isn’t to say short fiber is bad, but it can still be used but maybe not for spinning, or carpet/rugs, instead felting, which we talk about in Part Four using fiber.

The most important quality is fiber diameter, also called micrometer. Wool is not hollow. However, it can absorb 1/3 the fiber weight in water. Due to the lanolin on the fibers, it can also make wool water resistant.

Some examples of micrometer size of various animals (wikipedia)

Animal Fibre diameter
(micrometers)
Vicuña 6–10
Alpaca (Suri) 10–15
Muskox (Qivlut) 11–13
Merino 12–20
Angora Rabbit 13
Cashmere 15–19
Yak Down 15–19
Alpaca (Huacaya) 15-29
Camel Down 16–25
Guanaco 16–18
Llama (Tapada) 20–30
Chinchilla 21
Mohair 25–45
Llama (Ccara) 30–40

Here is a sheep table of wool micrometer from Wild Fibers. 
Bradford cound is a new term for me which I learned from Wild Fibers.

Bradford Count
Bradford or English Spinning Count System is the number of hanks of yarn, each of 560 yards in length that can be spun from one pound of clean wool. The finer the fibre is, the more hanks that can be obtained from one pound of wool. The higher the number, the finer the wool, and therefore 64 is finer than 48.
Fibre Microns Bradford Count
Merino 18-24 80-60
Rambouillet 18-24 80-60
Icelandic 22-28 (55-65 outer) 70-46
Blue-faced Leicester 22-25 60-56
Southdown 23-29 60-54
Finnish Landrace 23-31 60-50
Shetland 20-33 60-50
Shropshire 24-33 60-48

Crimp is another critical criteria for fiber. Hand spinners, like to have higher crimp. Fibers with a fine crimp have many bends and usually have a small diameter. So think of a corrugated roof tin or the inside of cardboard. The waves back and forth. Such fibers can be spun into fine yarns, with great lengths of yarn for a given weight of wool, and higher market value. The crimp allows the fibers to interlock with each other. If there is little to no crimp the fibers wont grab each other.

Below are some examples of sheep for comparison.

This is Ramona a Rambouillet ewe who has dense fine wool with nice crimp. This is the equivalent to merino wool.

This is a picture from Pixie one of our Finn ewes who has high crimp but not as dense or fine fiber

Below is Olaf a Shetland ram who had medium crimp, dense fibers but a larger diameter

This is Scotchie who is a Scottish Blackface and has little crimp but long coarse fiber. She is also double coated.

These are just examples of sheep and they can be blended together for the final intended purpose. More on use of fiber in the next article. But you wouldn’t use a fine wool with good crimp to make carpets, it would be a waste and wouldn’t hold up compared to a coarse larger diameter fiber. This link and associated article from Northwest Alpacas has more information than you ever wanted to know about crimp. Initially I thought there was no, light, medium and heavy crimp. I was way wrong.

Wool staple is a naturally formed cluster or lock of wool fibres and not a single fibre. Very many staples together form a fleece. The cluster of wool fibres is made by a cluster of follicles. The natural cluster of wool is held together because individual fibres have the ability to attach to each other so that they stay together

Lastly color. Color can ultimately be tied to what you want to do with it. Personally, I find white fiber to be more desirable, as you can color it easier. There is a downside, that it shows dirt and foreign organic material much easier and thus must be cleaned more thoroughly. If you were to get a colored fleece, then again, personally I would want it uniformed in color, because there is less blending needed to be done to get a uniform color. This is my personal preference, BUT, having a fleece with varying colors and used int eh right way, can give some amazing looks to hand crafted items. Because multi colored fleeces are unique, then the shearing, cleaning, carding, spinning, and use of the material will never be able to be duplicated, you can have something truly unique. In the end what one person things of as poor quality, another my find high because of the end use. You can see some of the color patterns of our animals on the Our Animals page.

Part Three will be on fiber processing. I thought I knew the process, but more like I knew the 10,000 foot view of it. I will give you the 10,000 foot view and maybe 1,000 foot. There is a LOT to processing. When you realize what goes into the fiber, to get it from animal to what you wear/use you would be shocked.

 

Not all fiber is wool Part I

As I started to write this, it quickly became larger than I expected so I am breaking it down into sections. Part one will be about types of fiber. Part two will be dedicated to quality of the fiber. Part three will be processing fiber.  Part four will be using the fiber. I never really knew there was so much to fiber. We are in no way experts, we are just sharing what we have learned along the way.

For someone who isn’t into spinning, fiber, and the wool world understanding what the differences are can be daunting. We were in this boat about five years ago. We assumed all animals you shear provide wool. Not the case. Sheep provide wool. So what do you call the material from llama, alpaca, or better silk worms? A friend who has now become family started educating us. It is all called fiber. There are different types of fiber, from different sources, different qualities and that also goes for natural vs man made fiber. For the most part we want to focus on natural fibers. We will try and break down some of the lessons we have learned, and point you to places so you can learn more.

Fiber can come from many sources, not just animals. Take the silk worm for instance. The fiber comes from the cocoon of the silk worm moth.  Wee aka Jr. Farm Boss and I found one on the farm one day but had no idea what we had. Using the Insect Identification Page on Facebook we were able to tell we had in fact found a native Indiana silk moth. Antheraea polyphemusThese native species are not great at producing usable silk for working with like you would think of for a silk scarf. But still pretty cool.

Cocoon
Pupa

We tried our hand at raising production silk worms as you can feed them native mulberry leaves here in Indiana.  They are ravenous little creatures. Sadly we never made it to the cocoon stage.  They only like fresh leaves, and are very fragile.  We may try it again someday but at the time had way too many projects going on to properly care for them. If you are interested in raising some check out Worm Spit. I would suggest wait until the warmer months, when you can have access to fresh mulberry leaves. Be prepared, they eat a lot, and you may run out of branches you can reach quickly.

There is a whole magnitude of fiber that comes from plants. Most people immediately think of cotton. We have some local friends here in Indiana at Stillwater Farms who grew cotton this year (2017) on their farm. We were always under the impression that it was a southern state crop. Learn something new all the time. Their cotton wasn’t a large scale production, but more an experiment to see if it could be done, and have the experience. Cotton production on a large scale takes specialized and expensive equipment.

Have you ever seen a cotton blossom? We haven’t. Thanks to Yvonne at Stillwater Farms for the picture.

In addition to cotton there is hemp which is far more sustainable and ecologically better than commercial cotton. Unfortunately the Indiana legislature still considers hemp, which has by law less than 0.3% THC (the active compound in getting people high associated with marijuana), A Schedule I  narcotic. A  Schedule I is said to have no medicinal value and Indiana and Federal legislature group marijuana with heroin, LSD, and ecstasy, Locally Indiana Hemp Industries Association has been on the forefront of getting hemp legalized here in Indiana. Hemp can replace many synthetic products or materials from ecologically damaging practices from fuel, to animal feed, to toilet paper, to fiber used in clothing. The IHIA has more information on their website and how you can help if interested. Up until the 1938 hemp was grown as a crop here in Indiana.

Yucca is another fiber product you can grow here in Indiana. While not suited for clothing it can be used for rope and crafts. Did you also know the roots of the yucca can be eaten,  made into a flour for baking. and even a shampoo and soap?

We have several different animal sources of fiber on our farm. Contrary to what PETA or other animal rights groups you DO NOT KILL an animal for fiber. Many times shearing the animal improves the animals health and comfort. Imagine, a typical Indiana summer, and you are wearing your heaviest winter coat, two layers of pants, and a hat. You would be hot, right? These animals are too. We only shear in early spring for sheep (helps with lambing) and late in spring for alpaca and llama. Why the difference? Ewes (female sheep) won’t feel the chill of early morning spring air with a heavy coat on. They will give birth in the field and not realize the lamb is cold. If they are shorn they will want to move into the barn, so the lamb and ewe will have a similar experience of temperature. We bread later in the season so that outside temps are warmer, and try to isolate ewes ready to give birth in the barn, but sometimes they surprise us.

You can learn more about individual animals or their breeds at the Our Animals page.

We have Sheep

We have a variety of pure sheep and several crosses. Each fiber has different qualities which we will discuss in part two.

Llama

Initially the llamas were here to help keep the pastures mowed and protect some of the other animals. Shearing for fiber was just a bonus.

Alpaca

All of our alpacas are the Huacaya  (pronounced wuh-kai-ya) breed.

Goat

Yes goat….Many people don’t know that the expensive angora (although typically associated with rabbits), cashmere, and mohair sweaters and clothing comes from GOATS.  Here are all the goat fiber breeds.  We have “Token” aka Norman a Pygora goat. While he wasn’t initially brought to the farm for fiber, we have grown to like it.

We will soon be adding rabbits to our fiber animals. Initially as a pet, but possibly production animal as well. Angora rabbits are another source of super soft fiber. Want to learn more about Angoras? Friends at Treen Acres has some info and pictures.

  

Surprisingly you can also use dog and cat hair as fiber. Jack and Freyja our LGD/Farm Dogs have a dual coats and they “blow them out” each spring. Blowing out a coat means the thick fluffy layer underneath that keeps them warm over the winter falls out and they regrow it again in the fall. Major, well, not much to say about Major other than “He’s so FLUFFY!!!”

Cows

In the distant future we hope to add Scottish Highland cattle which has fiber you can use in fiber works. At this time we cannot speak to the quality of the fiber. Aren’t they fluffy looking. Adults have long locks of fiber.

 

Pigs?!?!?!

There is a type of wooly pig that also has fiber. The Mangalica is a wooly pig said to have fiber similar to some sheep.
