In daily life, people cannot leave the quilt for keeping warm. The quilt is a rectangular cloth with an area enough to cover a human body, and is generally used for keeping warm during sleeping, and is generally formed by covering a quilt cover or a quilt single with cotton wool. In the traditional quilt, a quilt core consisting of cotton wool is directly inserted into a quilt cover and then laid flat, and the quilt cover is covered for heating after the quilt core and the quilt cover are attached flatly.

The early cotton wool can be warmed in winter due to the thickness, and most quilts made of cotton are adopted, so the prior quilts have the thickness, and the situation that the quilt cover is only pulled but the cotton wool is not pulled can not occur when the quilt cover on the surface of the quilt is pulled. However, with the improvement of living conditions of people, the lighter the weight of the existing cotton wool is, the better the heat preservation effect is, for example, the cotton wool is made of artificial fibers such as wool, silk or acrylic fiber; the materials of the quilt cover are gradually diversified and advanced. Therefore, with the change of the material of the quilt and the development of light weight, the following phenomena are easy to occur in the using process:

the cotton wool in the quilt cover is shrunk into a group when the quilt cover wakes up, the four corners or the edge zones of the quilt cover form a vacuum shape, and the quilt cover and the cotton wool are arranged in a time-consuming and labor-consuming manner before the quilt cover is used again, so that the quilt cover and the cotton wool are completely attached.
