I would like to prefer the wool fibre which is obtained from the fleece of the sheep and it is the good conductor of heat
Yes, but on a low heat like 130, or depending on how good quality the fibre is you could go up to 180 MAXIMUM heat,
Unless your fibre contains metal, it has no heat conductivity.
A layer of fleece is good at reducing the transfer of heat because it is a good insulator. Fleece traps air between its fibers, creating a barrier that helps to slow down heat transfer. This makes it effective at keeping you warm in cold weather.
The glass fibre would be OK but the polyurethane resin is not heat resistant.
Fiberglass is a good insulator of heat. It is often used in homes and buildings to help regulate temperature by reducing the transfer of heat between different spaces.
A layer of fleece is good at reducing energy transfer because it traps air within its fibers, creating a barrier that slows down the transfer of heat. This trapped air acts as a thermal insulator, reducing the amount of heat that can escape or enter through the material, thus helping to maintain a more stable temperature.
when you sleep next to them they can feel your heat but when you move they lose that heat they get from you.and they can fell the vibration when you move. cats have good feeling senses
Sleeping bags are good insulators because they trap and retain body heat within the insulated layers, preventing it from escaping into the surrounding environment. The materials used in sleeping bags are typically designed to limit heat loss and create a barrier against the cold, keeping the sleeper warm and comfortable during rest. Additionally, the snug fit of a sleeping bag helps to reduce air circulation and further enhances its insulating properties.
Sleeping Bags don't actually provide the heat, it is when our body heats us and he bag insulates (keeps) the heat in the bag. That is why we can get constant heat from the bag.
Materials such as aluminum, copper, and silver are good reflectors of radiant heat due to their high thermal reflectivity. These materials have the ability to reflect a high percentage of heat energy, making them effective in reducing thermal transfer.
Materials such as aluminum foil, silver, and reflective paint are good heat reflectors. Insulating materials like fiberglass, foam board, and cellulose are effective at reducing heat transfer and insulating against temperature changes.
