no, wool should stay on sheep, not be made into jumpers. how would you like it if someone shaved all your hair off to make a wig?

Interesting question!
Apparently, wool does not shrink, it "felts" as the fibres of wool (which have scales that are like tiny hooks) catch on one another and get entangled and knotted.
The fact that wool "felts" is useful - for when wool is spun, these hooks interlock to help to keep the yarn together (as well as the twist that is inserted).
On a jumper, felting usually occurs in the presence of heat, water and agitation, and this acts as a ratchet, tightening the contact between the fibres in the yarn, and then the yarns in the fabric.
Shrink-proofing is a chemical treatment of wool, which uses chlorine to "burn" off the scales that "catch".
This doesn't entirely remove the scales, but it does make them smaller and then the fibres are coated with a resin to smooth the fibre still further, so even less catching can occur.
This allows the wool to be machine washed without "felting", and the shrinkage of the fabric associated with felting.
The reason a sheep does not shrink is that the fibres in a fleece on a sheep are all growing out of the follicles in the same direction, and generally speaking, they all grow at a similar rate.
This means that the cuticle scales (which are a bit like the tiny teeth on a saw) are all pointed in the same direction. They don't catch on one another. These scales can be seen clearly in electron micrographs.
After the fleece is shorn, the processing stages cause the natural fibre alignment to be completely disrupted and the fibres no longer line up "tip to base" as they would in the fleece.
They can be in all dimensions and also suffer entangling after scouring and drying. The scales now can be at 180 degrees to one another, and can catch on one another.
Other animal fibres have cuticular scales also, but to different degrees. For instance, the scales on human hair are much flatter. Fine diameter wools are more likely to felt than broad diameter wools because they have a greater surface area, and hence more scales proportionately.

in basic terms a guess yet Sheep's wool is roofed in an oily substance all of us understand of as lanolin. it somewhat is faraway from the fibers formerly turning out to be yarn. That substance is then utilized in many splendor products. It in all probability makes the water bead as a substitute of soak in.

Yes, it does. Why do you think there are so many tiny little sheep in April? April showers, small sheep!!! It's no coincidence!!

Yes. Otherwise they would be huge.
