How can I say in very good scientific language why Wool is a good insulator for heat?

Question

I need to explain in my Science soursework why Wool is a good insulator for heat in very detailed scientific words. Can any1 help me out plzzzz. I also need to explain why Fur is better than Wool in insulating heat? This is becuz in a science experiment, I covered 2 test tubes filled with boiling water in those two materials (one material per test tube ) and Fur lost the least amount of heat. Wool did not lose a lot either therefore I know they are both good insulators I just need to explain why Wool is a good insulator but why Fur is an even better one???? plzzzz help me
