In some cases it's the same thing. If it's mass produced there may be some acrylic or pollyester blended into it.
because the yarn in the sweater is cleaned and died and the wool on the sheep is not
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.

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
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.
Yes. Depending on the size of the sweater and the weight of yarn used, a knitted sweater may use up to 1000 or 2000 yards of yarn. The average ball of worsted weight yarn contains about 200 or less yards, so it is not only possible, but necessary to knit a sweater with more than one ball of yarn.
Soft, fluffy, whatever you think of when you hear "cotton wool".
