Steps of processing fibres into wool;

1. Sheep Wool comes from sheep. They grow a wool coat and once a year this wool coat is sheared off the animal. In Wisconsin, thisis frequently done in the early spring shortly before they have their lambs. A shorn ewe will be more likely to stay out of the wind and bad weather and protect her new-born lamb if shedoes not have a thick wool coat on her.
2. FleeceThe shorn wool coat is called a fleece. It is also called "grease wool" because of all the oil and lanolin in the wool. This fleece must be cleaned before it can beprocessed into wool yarn. There is much vegetable matter, manure and natural oil that mustbe removed. Sometimes as much as 50% of the weight of the fleece is not wool.
3. Skirting a fleeceThe wool from the back end of the sheep, their legs and sometimes their belly is too full of manure to use. These are referred to as "tags" (as in the phrase "tag end"). These are removed first before washing the fleece; this process is called skirting, as all the edges of the wool coat are removed. The fleeces are also sorted into the various types: fine from coarse and short from long.
4. Washing the woolThe grease must then be removed from the wool. This can be done using soap or detergent and a lot of water or it can be done by submerging the wool in an acid bath which dissolves all the vegetable matter as well as the grease (this is called scouring).
5. PickingThe washed and dried wool is then "teased" or "picked" which is the beginning of the process of opening up the locks of wool and turning it into a consistent web. The wool is put through a picker which opens the locks and blows the fluffy wool into a room. At the same time a special spinning oil is added which helps the wool fibers slideagainst each other but also helps them stick together as a fine web through the processing.
6. CardingThe wool fibers are then put through a series of combing steps called carding. This can be done with small hand cards that look much like brushes you would use on a dog. It can also be done on a larger scale with machine driven drums covered with "card cloth" which combs the wool many times by transfering it back and forth from one drum to the other as it is passed down the series of drums. We have "woolen"cards which produce a wool web with the fibers coming off in random alignment. This is in contrast to"worsted" combing that lines up all the fibers (as you would see in thread).
7. RovingThe final step in the carding process divides the web into small strips called pencil rovings. These are collected on large spools on the end of the card. These spools of pencil roving will be placed on the spinning frame to make yarn. Pencil roving is too delicate to be handled much, so when proccessing fiber for handspinners the roving is takenoff the machines earlier and wound into balls.
8. SpinningThe roving as it comes off the card has no twist. It is held together by the oil and natural hooks that exist on the surface of the wool fibers. The spinning frame will put the actual twist onthe roving and turn it into yarn. This is collected on wooden bobbins. The frame we have is small but it can spin up to 90 threads at one time. This only spins one ply yarn (single stranded), which is not as sturdyas most prefer. In order to maketwo or more ply yarn the strands are twisted together on the plyer,from several cones onto fewer spools.
9. Wind and/or skeiningWhen the wooden bobbins are full of yarn, they are placed on a cone winder and the yarn is transferred to paper cones for use in weaving and knitting machines. It could also be put into skeins of yarn which are theform that knitters like to use.
10. FinishingThere are many ways of finishing the yarn. It is sometimes necessary to removethe lubricant by washing, which also "sets the twist" which allows the fibers to open up, fluffout and make a loftier yarn. Sometimes the wool is woven orknitted directly from the cone and is washed and blocked in itsfinal form (as cloth, socks, sweaters, etc.).
