because the yarn in the sweater is cleaned and died and the wool on the sheep is not
No, cotton is made from the fibers of the cotton plant, while sheep produce wool which is used for yarn and fabric. Cotton fibers are harvested from the cotton plant's bolls and spun into yarn for textiles, while sheep are shorn to obtain wool for making fabric.
The number of sheep required to make a sweater varies by two things: 1. The yield of wool from the particular breed of sheep, and 2. How light or bulky the sweater is. Most "all-wool" sweaters weigh between about 3/4 lb. and 1.5 lbs., again, depending on the sweater's size and thickness. The most numerous sheep breed in the U.S. is probably the Rambouillet, which typically will yield around 12 to 15 lbs. of "grease" wool (that is, unwashed). After washing the wool, you may have about 5 to 7 lbs. left, of which 4 to 5 lbs. will end up in the yarn for the sweater. For those breeds you can likely get 3 to 4 sweaters--more if they're loosely knit and/or of small size. For wool sweaters that have more bulk, and are therefore warmer, one would move towards breeds such as Romney with stout-fiber, through to the Columbia with the slenderest fibers of the medium-fiber class of breeds. Medium-wool breeds yield slightly fewer pounds per animal in clip, but there's a good bit less grease (lanolin) that must be scoured out at washing. Most of the weight of grease is its adhering dust and dirt. With medium-wool breeds, you can't make really light and flimsy type sweaters. Still, you should get 4 to 5 sweaters, easily. One may also use wool from the true longwools--Cotswold, Leicester, Lincoln, Teeswater & Wensleydale. Wool from these breeds tends to be less "springy" or "bouncy," but sturdier, and can really stand the abuse of outdoor activities--particularly in the woods and brush. The first 3 mentioned are especially sturdy. All true longwool breeds produce very shiny, lustrous wool. Lincoln and Cotswold rams commonly produce well over 20 lbs. of wool per year; ewes, about 12 to 15 lbs. Some Lincolns--well fed with plenty of grain and top hay--could yield over 30 lbs. These breeds typically have a very high percentage yield, and you may very well end up with 10 or more pounds of yarn for your sweater, but it will likely be rather bulky and warm. A ballpark figure for longwool sheep should be about 4 to 6 sweaters per ewe per year, and for rams, probably 6 to 8 sweaters. Ask your supplier how much a specific ewe or ram yields each time it's shorn. Bear in mind that many modern longwool growers clip twice a year, so fleece weight may be only half the annual yield. Ask also how much the scouring yield is. From that figure, count on losing about 20% more or less in the carding and spinning operations. For numerous web-accessible articles on sheep, wool and how growers can supply them to buyers, search "sheep magazine" in any web search engine. Data in the magazine articles often show clip yields and uses for specific breeds. In the United States alone there are over 60 breeds, many of which don't yield wool at all, and certain crossbreeds' wool could be full of hair, which makes for a very prickly sweater.
A group of wool is typically referred to as a skein or a ball of wool, depending on its form. A skein is a length of yarn wound in a loose loop, while a ball is yarn wound into a round shape.
A braided wool woven rug is made from clean wool, that has been formed into a yarn, then woven into a rug. The first step in making a woven wool rug is to decide how much wool is needed for the final project.
No. A special breed of Himalayan goat sheds its hair every year. This hair is made into the finest, most expensive type of yarn known to us as Cashmere.The goats have been grown commercially with great success, and they are brushed during their shedding season to collect the wool. It is still the same fine quality, but it much more abundant today than it was in the past.This is a renewable product and does not harm the goat in any way.
Wool
Yarn from sheep means that the wool used to make the yarn was harvested from a sheep, rather than an Alpaca, Yak or some other wool producing mammal.
Wool.

In some cases it's the same thing. If it's mass produced there may be some acrylic or pollyester blended into it.
It all depends on what kind of sweater you're thinking of- knit sweaters are made of wool or yarn (i think) some are made of cotton, and polyester, and 100% rayon (probably) You should look it up! Hope this helped!
It depends on what size the sweater is intended to be and the weight of the yarn to be used. A medium woman's sweater (40") will take about 12 oz fine (sport) wool, 20 oz. medium (worsted), or 28 oz heavy yarn.
Just like sheep, the wool of an alpaca can be used to make really soft yarn.
Um... I think your talking about wool. It has four letters and comes from sheep. :D
Soft, fluffy, whatever you think of when you hear "cotton wool".
You need a full grown sheep. Sheer her and get Wool. Then you need a Maker Shed. Once you have that you can buy a Yarn Maker. When you've got that drop the Wool into the Yarn Maker and then you'll get a ball of Yarn.
You may be able to unravel the sweater, and in so doing as you wind it, you'll end up with a ball of yarn. If the yarn is plyed -- twisted, you may be able to unply the strands. You will not be successful in 'un-spinning' the fibres that make up the yarn.
