The more fibers in the same space, the larger the insulation layer formed on the fiber surface to block thermal radiation, and the warmer the material, which requires the fiber to be thin; The more air remains in the fiber, the less heat loss is transferred, and the higher the heat insulation efficiency of the material, which requires the fiber to be hollow.
Thin and hollow, which is the characteristic of thermal insulation materials. Outdoor clothing is famous for its functionality, and there are many kinds of warm-keeping materials. The following is the explanation of fleece, cotton and down. Wool, commonly known as polyester fiber, has extremely fine fineness, so it has warm keeping performance.
Fabric density and gram weight are the main basis to measure the thermal insulation performance of a fleece garment. It follows the principle that the more fibers, the larger the thermal insulation layer formed on the fiber surface area to block thermal radiation, and the warmer the material. But generally speaking, measuring the warmth retention of wool depends on the gram weight. The greater the gram weight under the same material, the better the warm-keeping function.
