In the past, in order to achieve the purpose of keeping warm, clothes are usually made of high-density or multi-layer fabrics. Although this type of fabric is warmer to use on clothes, it is thicker and less comfortable to wear. Bed bedding equipment is made of such fabrics, such as pillows, quilts and bedspreads. It is rarely moved because of the fixed position. Although it is cumbersome, consumers are still acceptable, but there are also no use. comfortability.

In order to improve the above-mentioned defects, down jackets and bedding equipment have been manufactured on the market, mainly by filling a layer of feathers filled with animal feathers such as duck feathers, goose feathers, etc. between the two layers of fabrics. The so-called down jacket and bedding bedding equipment can not only use the down filling layer to achieve warmth, but also greatly reduce the weight and comfort of the clothes, so it is widely loved by consumers.

However, the down filling layer of the conventional down jacket and bed bedding equipment is taken from the feather of the animal, and may be mixed with a spike such as a feather thorn, a feather hook, etc., and the fabric covered with the down filling layer is covered. They are all woven from yarn, so there are some small gaps between the yarns or the yarn itself. When the down of the down filling layer and its spikes pass through the gap of the fabric, not only the user but also the fabric is easily damaged.

In order to improve the aforementioned defects, although a manufacturer adds a spacer layer between the cloth and the down filling layer to prevent the spikes from penetrating the cloth, the barrier layer blocks the circulation of air, and therefore the sweat of the human body cannot be discharged.
