Because cotton has little spaces that air can go through, and that makes the insulation last longer. It gets rid of the cold/hot air, and lets the product in the insulator have most of the air temperature it needs.

∙ 14y agoCotton is a good thermal insulator because it traps the air. Heat loss occurs when the body is exposed to cold air. The skin loses heat to the surrounding cooler air through conduction. Without an insulator like cotton, the air currents constantly replace the air around the body, keeping the air at the same ambient temperature. But a cotton shirt creates a trapped layer of air around the body, and without the air currents replacing that air, the trapped air warms up, thereby keeping your body warmer.
Because trapping air is a good way to insulate yourself, it is better to wear more thin layers than one thick one.

Why is cotton balls a good insulator?
cotton balls are a good insulator because they contain many air filled spaces, the tiny pockets trap air in the cotton balls preventing energy from being transferred. So there is less heat transfer.
Is cotton a better insulator than aluminium foil and tissue paper?
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.
Is cotton a good inslator?
cotton is a good insulater yes cotton is a good insulater because it adsorbs sound
What fabric is a good insulator wrapped around a jar?
If you use a glass jar, it is already an insulator
Is plastic a good insulator of heat?
yes i think A2: No, Not in Solid form. It is a Very Good insulator If sprayed into closed-cell foam or spun into fabric.
Is a good insulator?
cotton wool
What is a good thermal insulator?
cotton wool
Why is a cotton clothing a good insulator?
Cotton keeps its heat very well.
Is cotton an insulator or a conductor?
semi conductor
Is cottom wool a good insulator?
Cotton wool has a very low density and has thousands of pockets to trap air in. Because of this, cotton wool is a good insulator, but there are others that are better. As a rule of thumb, the lower the density, the better the insulator. There are virtually no exceptions to this.
Is cotton wool a conductor of electricity or an insulator?
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.
Is coton a good insulator?
Cotton is a moderate insulator, and cotton covered wire was often used in low voltage applications. (Probably completely replaced nowadays by insulating varnishes.)
Is a cotton ball a conductor or a insulator?
insulator
Why is cotton balls a good insulator?
cotton balls are a good insulator because they contain many air filled spaces, the tiny pockets trap air in the cotton balls preventing energy from being transferred. So there is less heat transfer.
What is a better insulator Styrofoam or cotton?
cotton
Is cotton a insulator or a conductor?
It is a insulator since it is not metal
Is cotton wool a good heat insulator?
because it can keep heat in because it is thick and good for insulation
