no, but it traps heat b/w its layers
Wool holds lot of air. As air is a bad conductor of heat, this makes the wool a bad conductor of heat, but a good insulator.
Cotton And Wool
thermal, electrical, chemical, or radiation
Silk is well known for being warmer than wool. Nylon and cotton are poorer insulators. (As well, there are other types of "wool" which are known for being much warmer than sheep's wool...)
when heat gets transferred along objects it is called conduction, different substances are better at conducting heat than others. for example, metals are good heat 'conductors' because the vibrating particles transfer energy along the metal object fast. but certain objects don't conduct heat very well and are called 'insulators'. an example of an insulator is wool, mainly because wool traps quite alot of air, and air is a terrible conductor due to how much the particles are spaced out.
Fleece-bearing animals are the source of wool fibres.

A wool sock is made of wool, the source of which is animal fleece.
wool!
wool
A wool sock is what it sounds like... A sock made from wool... You get wool from a sheep.
yes it is because wool has air pockets which keep in all the heat and block out the conduction of heat, convection and radiation.
the yak is a source of wool and milk mainly...!!
wool is a insulator
yes and no it depends on what wool and what you want to insulate ?
As wool keeps you warm and retains body heat
Animals that grow fleece are the source for the raw material that is made into wool.
