The material of the moisture absorption layer 2 is wool fiber. The natural fibers have certain moisture absorption and heating performance, and particularly wool fibers are obvious. Generally, the heat generating performance of the hygroscopic exothermic fiber is related to the moisture regain thereof, and the hygroscopic exothermic performance is excellent when the moisture regain is high. When the wool fiber absorbs moisture, fiber molecules and water molecules are mutually attracted and combined, the kinetic energy of the water molecules is reduced and converted into heat (energy) to be released, and therefore the heating effect is achieved.

The down filling layer 3 comprises a first down prevention layer 6; the upper end of the first down-proof layer 6 is provided with a moisture absorption layer 2, and the lower part is provided with a second down-proof layer 8; the first down-proof layer 6 and the second down-proof layer 8 can more effectively play a role in down-proof. A down layer 7 is arranged between the first down-proof layer 6 and the second down-proof layer 8; the lower end of the second down-proof layer 8 is provided with an inner material layer; the heating and warm-keeping layer 4 is tightly connected with the second down-proof layer 8 through hot melt adhesives distributed in a dotted manner, so that the firmness of the fabric can be enhanced.
