Description

[Detailed description of the invention] This invention does not cause the internal filling material to sag as it is used as in the past, and the filling material is a low-volume fiber cushioning material that is hard and soft on the front and back. The purpose is to easily obtain a convenient futon that can be used both in winter and at a low price.

The present invention involves adding a small amount (10 to 15%) of high melting point synthetic fibers such as nylon, polyethylene phthalate, polyvinyl chloride, polyester, polyacrylic to 100% of low melting point synthetic fibers such as polypropylene, polyethylene, polyvinylidene chloride, A small amount (15~
20%) of low melting point synthetic fiber 1 is polymerized and heated and compressed at 130°C to create a futon with a hard surface on the front side and a soft surface on the back side. Fiber laminates A and B are formed.

That is, the batted cotton layer A is a mixture of low melting point synthetic fiber 1 and a small amount of high melting point synthetic fiber 2, which is heated and compressed at a low melting point of 130°C, so that the low melting point fiber leaves the high melting point fiber and changes to the point where it is on the verge of fusion. On the other hand, since the batting layer B has a small amount of low melting point synthetic fibers 1 mixed with high melting point synthetic fibers 2, only the low melting point fibers soften when heated and pressed just before they fuse, forming high melting point synthetic fibers 2. Since it is only bonded and connected, it retains its flexibility, so when it is heated and compressed as a polymerized unit, it becomes an independent fiber laminate A with a hard surface on the front side and a soft surface on the back side.
Form B.

Then, these two independent fiber laminates A and B are polymerized by separately applying sewing machine stitches 3 across the width at equal intervals, and the - side of these is covered with a raised fabric 4, and the other side is covered with a raised fabric 4. The structure of the futon is characterized in that each piece is covered with a plain cloth 5, and its periphery is wrapped and sewn with a hem cloth 6 to form an integral piece.

This project consists of the above structure, with independent fiber laminates A and B.
Since two sheets of fiber laminate A and B are polymerized, the first fiber laminate A and B become batt layer A having a hard surface A on the front side, batt layer B having a soft surface opening on the back side, and the second fiber laminate consists of the polymerized fibers. The laminates A and B also have a hard surface A on the front side and a soft surface hole on the back side, so by this polymerization, the entire surface becomes a hard surface A and a soft surface hole on the back side, with a soft surface hole and a hard surface A interposed between them. As mentioned above, it becomes bulky due to heating and pressing, and when used as a mattress, it feels elastic as if there is a spring interposed in the middle, and the internal filler does not sag as it is used as in the past. It has the characteristic of being low in bulk.

Since two independent fiber laminates A and B are polymerized, they have excellent heat retention, and as mentioned above, the front side is a hard side and the back side is a soft side, so the hard and soft sides can be freely reversed and used as necessary. It has characteristics.

In addition, each of the two polymerized fiber laminates A and B is machine-stitched separately across the width at equal intervals, so that the machine-sewn seams 3 form creases, making it foldable and low-volume for storage in closets, etc. It has features that make it easy to move and transport.

Furthermore, since one side is covered with the raised fabric 4, its flexibility and hardness blend well with the hard surface A, making it suitable for winter when heat retention is required.The other side is covered with plain cloth 5, making it suitable for summer. It has features that make it suitable for both winter use.

In addition, in order to integrate these items, the periphery of the front and lining fabrics 4 and 5 is covered with a hem fabric 6.
Because it is wrapped and sewn into one piece, it is strong and has high resistance to force.
It is extremely suitable for use in futons.
