FIG. 2 is a cross-sectional view of a multi-layered four seasons pad according to an embodiment of the present invention, and FIG. 3 is a cross-sectional view of another embodiment of the present invention. Sectional structure of the multi-layered four seasons.

A multi-layered four-seam pad 1 according to an embodiment of the present invention includes a first outer layer 11 formed to have a surface exposed at one side thereof, a second outer layer 11 bonded on the other surface of the first outer layer 11, A second filler 22 having a thickness greater than that of the first filler 12 and having one side thereof facing the first filler 12 and a second filler 22 bonded to the other side of the second filler 22, The second outer sheet 21 is laminated.

The multi-layered seasonal pad 1 according to an embodiment of the present invention is a pad having a multi-layered structure made of different materials so that the user can selectively feel a cold sensation corresponding to each season. The thickness of the entire pad is increased to provide a cushioning feeling, and each different material corresponding to the outer surface is applied to the surface of the pad, in addition to using the outer surface of the cool or warm material which is in contact with the user on one surface and the other surface of the pad. So that a multi-layered functional pad usable in all seasons can be realized.

On the outer surface of the pad 1, a first outer sheet 11 which is in direct contact with the user is formed. The first outer layer 11 is exposed on one side and the first filler 12 is bonded on the other inner side. The first outer layer 11 may be formed to include a face, an eye, or a combination thereof. By arranging the pad 1 so as to form the first outer surface 11 as an upper surface in spring or summer, the user can feel a cool feeling when laid on the first outer surface 11. In addition, by bonding the first filler 12 to the first outer surface 11 with a material including cotton or cotton wool, the cushioning feeling can be realized together with the coolness. The first filler 12 may include a larger amount of cotton, cotton or polyester cotton than the general product, so that the first filler 11, together with the coolness, can do. The first outer layer 11 may be joined to the first filler 12 by a quilting process. In this case, since the first outer layer 11 is located on the outer side, a more compact quilting process is performed. The first outer sheet 11 having a harder feeling can be realized. Therefore, in addition to the sense of cushioning by the first filler 12 as the pad 1, it is possible to provide comfort to the user's body.

Although the first filler 12 has been described as a cotton or a cotton pad, it is possible to apply a variety of natural or artificial materials such as a polyester cotton that can give a cushioning feeling, along with the coolness of the first outer cloth 11. However, the first filler 12, along with the first outer sheet 11, may be applied to materials that can provide a cool feeling in spring or summer.

Specifically, the surface of the fabric such as cotton, linen, and poly may be processed to give a feeling of embossing to give a cool feeling, ripples, and thin and woven gauze using cotton, silk, and rayon may be applied as the first outer layer 11 have.

The second outer layer 21 is bonded to the first filler 12 in the other surface direction which is the opposite surface to which the first outer layer 11 is bonded. The second outer sheet 21 is made of a soft material so as to give a warm feeling of autumn or winter. 2, the second filler 22 is joined to the second outer surface 21 and is joined to one side of the second filler 22 so as to face the first filler 12, The second outer cloth 21 is joined to the other surface, and the second outer cloth 21 is directly contacted by the user. The second outer surface 21 may be formed to include a microfiber fabric, Velor fabric, or a combination thereof.

The second filler 22 may include polyurethane or memory foam with a warmth of autumn or winter or a combination thereof. The second outer cloth 21 is disposed on the opposite surface to the first outer cloth 11 so that the first outer cloth 11 comes to the upper surface or the second outer cloth 21 comes to the upper surface It can be used selectively for each season. However, the second filler 22 together with the second outer sheet 21 may be made of a material capable of giving a warm feeling in autumn or winter. Accordingly, the second outer surface 21 can be formed by applying a heat-resistant material, a material capable of giving a thick thickness feeling, or a physical structure having a thick feeling. Specifically, an air layer may be formed on a space inside the second outer sheet 21 to form a predetermined thickness feeling, and a warm feeling of warmth can be given to the user through a thick laminated structure of the material itself. In an embodiment of the present invention, a pad combining the second outer sheet 21 and the second filler 22 is referred to as a lower pad 20 for convenience.

2 and 3, the first outer sheet 11, the first filler 12, the second filler 22 and the second outer sheet 21 are laminated and integrally subjected to a quilting process Q )do. Alternatively, as shown in FIG. 3, after the upper pad 10 having the first outer sheet 11 and the first filler 12 bonded thereto is first quilted (Q1), the upper pad 10 The second filler 22 and the lower pad 20 of the second outer sheet 21 can be quilted (Q2) together with the upper pad 10 in an integrated manner. After quilting, the pad 1 is completed by joining the side edges of the combined entire pad to the finish 30.

The first material 11, the first filler material 12, the second material material 21, and the second filler material 22 may be formed to be mutually replaceable. The first and second materials 11, It is needless to say that the terms themselves are not limited to each configuration.

4 to 9 are process drawings of a method of manufacturing a pad for a multi-layered four seasons according to an embodiment of the present invention.

A method for manufacturing a multi-layered four seasons pad according to an embodiment of the present invention includes the steps of preparing a first outer layer (11) having an upper surface exposed, and a filler (12) stacked on the other surface of the first outer layer Forming an upper pad 10 by quilting the first outer sheet 11 and the first filler 12 in a thickness direction in which the first pad 11 and the first filler 12 are laminated, A step of preparing a second filler 22 so as to correspond to one surface of the second surface 21 and the second surface 21, a step of preparing the stabilized upper pad 10 , Preparing the second filler 22 and the second outer sheet 21 to be laminated on the second pad 22 and the second pad 21 and the second pad 22 and the second outer sheet 21, Integrally quilting in the thickness direction; And joining the finishing material 30 to the side edge portions of the pad.

First, as shown in FIG. 4, a step of preparing a first outer sheet 11 and a first filler 12 coupled to the other surface of the first outer sheet 11 so that the upper surface is exposed. The first filler 12 is bonded to the inner surface of the first outer layer 11, and the first filler 12 is bonded to the inner surface of the first outer layer 11. The first filler 12 is formed of cotton or cotton wool to provide a cushioning feeling to the user. The first outer layer 11 is formed to have a cool feeling in spring or summer by the surface or the sight, and a cushioning feeling or a comfortable feeling can be realized along with the first filler 12 on the inner surface thereof.

Next, as shown in FIG. 5, the upper pad 10 is formed by quilting the first outer sheet 11 and the first filler 12 in the thickness direction in which the first outer sheet 11 and the first filler 12 are laminated. The quilting process is generally referred to as a singe beam process, whereby the first outer sheet 11 and the first filler 12 can be more firmly coupled. Considering that the first filler 12 and the second filler 22 described later are formed of different materials, the first outer sheet 11 and the first filler 12 are combined before the final combining process, A pretreatment process for the upper pad 10 may be added. In particular, when a product having a high shrinkage percentage such as cotton wool is applied and a difference in shrinkage ratio with a lower pad to be described later occurs, it is necessary to stabilize the shrinkage ratio beforehand so that the product is not defective during the washing and drying process of the end product will be.

6, the upper pad 10, to which the first outer sheet 11 and the first filler 12 are coupled, is subjected to a washing treatment at a high temperature and then dried by hot air, ) Is shrunk and stabilized. Washing treatment is a process in which enzymes are added at high temperature to remove impurities and contaminants, and the product itself is further softened by friction so that the feeling of use can be effectively improved. Particularly, in this process, since the first outer layer 11 and the first filler 12 are formed of a different material from the second outer layer 21 and the second filler 22 to be described later, And the occurrence of non-uniform defective products due to shrinkage and relaxation of the lower surface. That is, it is possible to stabilize the shrinkage ratio of the upper pad 10 by appropriately adjusting the processing time in the washing process within the range of 60 ° C to 100 ° C and the subsequent hot air drying process.

In the case where the first filler 12 is formed of the same material as cotton wool, the shrinkage that can occur during washing can be effectively stabilized by adjusting the processing time beforehand, And the shrinkage of the product during drying can be minimized. Here, the upper pad 10 has been described, but it goes without saying that the lower pad 20 to be described later can be selectively subjected to such a process depending on the material to which it is applied.

Accordingly, it is possible to further include forming the shrinkage ratio of the upper pad 10 to 5% or less by appropriately adjusting the processing time of the washing process of the upper pad 10 and the drying process of the hot air. By doing so, it is possible to fundamentally eliminate structural problems that may occur during washing or drying depending on the different materials of the upper and lower surfaces of the final product.

Here, the shrinkage ratio is effectively stabilized by controlling the processing time of the washing process and the hot air drying so that the shrinkage ratio of the upper pad 10 is set to be within 5%. The product stability and reliability of the other four seasons pads 1 can be improved.

When the shrinkage ratio is maintained in a range exceeding 5%, the final upper pad 10 and the lower pad 20 are quilted and joined together, and in the course of the additional washing or drying, 10 or a shrinkage due to a difference in shrinkage percentage of the lower pad 20 or non-uniformity of the upper and lower surfaces may result in product failure that can not realize the function of the pad product.

Next, as shown in FIG. 7, it is a step of preparing the second outer sheet 21 and the second filler 22 so as to be laminated on the upper pad 10. At this time, the second outer sheet 21 must be disposed on both outermost sides of the pad 1, together with the first outer sheet 11 of the upper pad 10. Accordingly, the upper pad 10, the second filler 22, and the second outer sheet 21 may be stacked in this order.

Next, as shown in FIG. 8, the upper pad 10, the second filler 22, and the second outer sheet 21, which are quilted (Q1), are sequentially laminated, And quilting (Q2). The upper pad 10 and the lower pad 20 which are sequentially stacked are bonded to each other by a quilting process.

Next, as shown in FIG. 9, the finishing material 30 can be joined to finish the entire pad stack side edge including the top pad 10, the bottom pad 20, and the like. Processing of the finishing material 30 produces the final multi-layered four seasons pad 1.

In addition, implementation of the multi-layered seasonal pad 1 described above such as the first outer sheet 11, the first filler 12, the second outer sheet 21 and the second filler 22 applied to the embodiment of the present manufacturing process The description of the structure of the pad 1 and the operation and effect of the pad 1 described above are omitted.
