wool i think.
wool
If I had to choose the best insulator out of steel wool, aluminum foil, cotton and bubble wrap, I would choose the aluminum foil.
An insulator.
wool holds lot of air.air being bad conductor of heat make the wool a good conductor of heat.
wool from sheep ... cotton from the cotton plant ....
Cotton fabric will burn faster than wool fabric. Wool will also be more difficult to light than cotton and may even self extinguish.
Wool is considered one of the best heat insulating fabrics due to its natural properties that trap air, creating a barrier against heat loss. Other good heat insulators are fleece and down feathers, which have a high loft and trap warmth effectively.
cotton wool
Cotton wool is not a conductor or an insulator it is a semi conductor. It is sort of in the middle, electrons can travel through cotton wool but not as good as silver, bronze, metal and so on.

Cotton wool is not as effective as other materials like wool or synthetic fibers when it comes to insulation. It can still provide some insulation properties but may not be as efficient in retaining heat or keeping out cold compared to other materials.
wool insulates heated water best because woll is the best insulator.
Yes sawdust is an insulator such as Wood, Plastic, Styrofoam, Rubber, Paper, Glass, Cotton, Sand, Aerogel, and Wool. Cotton and Wool is likely to be found in a sock. These insulators can stop heat or electricity from flowing through them.
Materials with high thermal resistance such as foam, wool, or fiberglass are commonly used as insulators to keep things warm. These materials trap heat and slow down its transfer, helping to maintain the desired temperature inside. Depending on the specific application, the best insulator may vary.
because it can keep heat in because it is thick and good for insulation
Coton is best as wool can hold more allergens then cotton
polysterene?
