1. Among the four natural thermal insulation materials, cotton, wool, silk and down, down has the best thermal insulation performance.
2. At present, there is no insulation material in the world that can surpass down in thermal performance. Because eiderdown has a radial structure, each feather filament can be seen under a microscope as a fish-scale structure, with countless tiny pores, and lots of still air.
3. The air conduction coefficient is the lowest, and the down is warm and elastic. Goose down, with 50% down content, was 2.8 times as light and fluffy as cotton and 2.2 times as wool. The duvet is not only soft and warm, but it also feels good to the touch.
4.Compared with other materials, goose down has a very good air permeability, has the function of moisture absorption and dehumidification. Goose down can absorb the water vapor from the body through the down wire, and at the same time, it can quickly disperse through the air, so as to achieve the effect of heat preservation.
