In general, multiple fabrics used as fabrics for clothes and bedclothes are constructed so as to form a sense of volume by inserting an adherend forming a cushion layer between the fabric layers forming the front and back surfaces.

In the case of the quilted fabric, which is a typical example of the multi-fabric, the quilted material such as cotton or wool is inserted between the two layers of fabric to form a voluminous feeling according to the bulkiness of the inner material,

The quilted fabric which forms the cushion layer by using an adherend such as cotton or wool forms a two-layered fabric through a process of separately weaving a surface and a back fabric using a weaving machine, I will also provide my charity through a separate process.

As described above, the natural quilted fabric of the quilted fabric is mainly used by using natural cotton, artificial cotton or wool as a raw material, and then processing the cotton in a sheet form corresponding to the fabric prepared in advance or using a unique chain structure Wool is processed into a sheet form and used.

For example, in Patent Document 10-2016- 0039703, there is known a method for producing a quilt cotton and a quilt cotton manufactured by the method, and a method for preparing the quilt cotton raw material, A step of preparing a prepreg cotton fiber sheet, a step of preparing a prepreg cotton fiber sheet, and a forming step of producing a prepreg cotton fiber sheet by laminating the perishable cotton fiber sheet, A step of covering the nonwoven fabric with a nonwoven fabric and a step of needle-punching the molded quilt-stranded fiber sheet covering the top and bottom of the nonwoven fabric spatially by a predetermined distance using a needle punching machine.

The quilted fabric and the fabrics prepared as described above are laminated, and the quilted fabric is stitched by using the predetermined quilting process, and the quilting process is sequentially performed to produce the quilted fabric.

For example, in the registered utility model No. 20-0185771, there has been known a technique of embedding a cotton or non-woven fabric between two pieces of fabric and forming a quilting fabric using the quilting, and the registered utility model No. 20-228399 A quilting fabric is known between the backing fabric and the backing fabric to incorporate a thermosetting material such as cotton or sponge. The technique consists of embedding cotton or other wrapping material between two separate fabrics which are individually woven and forming a quilting fabric by using quilting.

As another example, Japanese Patent Registration No. 10-1158791 discloses a method of manufacturing a Uebam bedding using wool as an adherend, wherein a cotton fabric is woven by cotton yarn and a woven fabric is fabricated so that wool does not protrude from the woven fabric Preparing a raw material for a surface material and a backing material, processing raw natural wool, selecting a woolen wool having a thickness of 10 to 80 mm and a weight of 112 to 224 g / m ² as a filling material, inserting a wool filling material between the surface material and the backing material, And a beam forming step of combining the surface material, the backing material, and the filler by pressing the bedding material with a punching machine.
