Lots of air pockets among the threads.
cotton wool
No, cotton is not a better insulator than aluminum foil and tissue paper. Aluminum foil is a good insulator as it reflects heat, while tissue paper acts as a thermal barrier. Cotton, on the other hand, is not as effective of an insulator because it does not have the same reflective or thermal barrier properties.
semi conductor
Air is the best insulator among the options listed. It has low thermal conductivity, meaning it does not easily transfer heat. Thermocol, cotton, and aluminium are not as effective as insulators compared to air.
Yes, fabric can be a good thermal insulator. Natural fibers such as wool, cotton, and silk are known for their insulating properties due to their ability to trap air. Additionally, specialized synthetic fabrics like fleece and thermal materials are designed to provide excellent thermal insulation.

An insulator has several different meanings. The two most common are an electrical insulator and a thermal insulator. an electrical insulator would be polyethylene. a thermal insulator would be wool.
No, acrylic is not a good thermal insulator. It has low thermal resistance and can allow heat to transfer easily.
cotton
insulator. it is not a very good insulator though.
Plastic is an electrical and thermal insulator.
It is a insulator since it is not metal
