Description

[Detailed description of the invention] This invention relates to the improvement of futons such as mattresses.

In general, futons such as mattresses are required to be bulky because they need to block cold outside air and maintain heat retention. By the way, traditional Japanese futons are made by wrapping around 5.5 kg of batting in the outer material and binding it in the required position, and recently, as shown in Figure 1, hard cotton 2 is placed in the center of futon 1. Then, the hard cotton 2 is wrapped with the batting 3 for Japanese binding 4, or quilting is applied to prevent the batting from moving. However, with either of the former Japanese binding methods, if the binding thread breaks or if the futon is used for a long period of time, the cotton may bunch or break, reducing its ability to block outside air, retain heat, or absorb and release moisture. I had a problem with the output being lost.

In addition, with the latter quilting method, if the futon is around 6cm thick, it cannot be quilted on a quilting machine, so the futon ends up being thin and lacking in bulk, which means it has poor air insulation and insulation ability.
Furthermore, when quilting is applied, the fabric is pulled toward the quilting seams, reducing the overall size of the futon and causing problems with its shape retention.

This idea involves making two quilted futon halves face each other with their mid-layers facing each other, securing their peripheral edges with a band-shaped gusset of the desired width made of flocked fabric, and attaching them to each other through a band-shaped gusset of a desired width made of flocked fabric. The above problem was solved by placing hard cotton on the inner layer and forming an air layer between the inner layers. The purpose is to provide a futon that has excellent shapeability and excellent moisture release.

This invention will be explained in detail below based on the drawings.

FIGS. 2 and 3 show an embodiment of this invention, in which the mattress consists of two futon halves 10. This futon half 10 has a filling of 11
It consists of an outer material 12 that covers the outer surface of this filling 11, and a middle material 13 that covers the inner surface of this filling 11,
The outer material 12, the batting 11, and the middle material 13 are integrally quilted 14 at required intervals to form a rectangular shape. The batting 11 has a two-layer structure, with shaped cotton 11a on the outer side and hard cotton 11b on the inside. The molded cotton 11
For a, ordinary cotton, synthetic cotton, wool cotton, or a blend of synthetic cotton and wool cotton is used, and for the hard cotton 11b, needle-punched wool cotton is used. It may also be hard cotton made by mixing 60% polypropylene and 40% polypropylene, heating the mixture to about 130°, melting polypropylene with a low melting point, and fixing the contact points between wool fibers as a binder. In any case, the quilting 14 is applied to the futon half 10, so
These battings 11 must be formed to a thickness (approximately 5 cm) that allows quilting 14 to be applied.

In this way, the batting 11 contains a large amount of air between fibers with low thermal conductivity, and has excellent heat retention and cold air blocking ability, as well as moisture absorption and
Since wool fibers are used, which are highly releasable and elastic, sweat can be absorbed quickly while sleeping, making it ideal as a material for the batting 11 of bedding. Further, when heat and moisture are applied to wool fibers, they are generally made into felt, but since the hard cotton 11b is needle-punched, it is already in a felted state and does not lose its bulk. In addition, hard cotton 11, which is harder than normal cotton, is on the inside 13 side.
b is stored, even if the quilting 14 is applied, the side fabric is not drawn to the seams of the quilting 14 and the overall size of the futon is not reduced, and the futon has excellent shape retention. Furthermore, if polypropylene is melted to fix the contact points between wool fibers, felting is prevented, so bulkiness is not lost.

In addition, the above-mentioned outer material 12 is made of cotton that is comfortable to the touch.
100% woven fabric is used, but the middle material is 13
Non-woven fabrics are used.

On the other hand, the two futon halves 10 configured in this way have their mid-layers 13 facing each other,
And a belt-shaped gusset 16 of a required width is fixed to the peripheral edge 15 of each insole 13, and the two futon halves 1 are assembled.
They are integrally provided with an air layer 17 formed between them. Further, this peripheral edge portion 15 is hemmed to fix the gusset 16 and the outer material 12, respectively. The gusset 16 is generally called sheep wool, and is made of a flocked fabric in which wool fibers, polyester, or the like are injected into the base fabric. In this way, two futon halves 1
A gusset 16 made of flocked fabric, which is thicker than normal fabric, is fixed to the peripheral edge 15 of 0, and the middle fabric 13
Since the hard cotton 11b is placed on the side to form an air layer 17 between the two fillings 13, the heat retention ability is further increased, and when this mattress is dried, the filling 11 Since the contained moisture is released into this air layer 17, drying becomes faster. In addition, since the peripheral edge portions 15 of one futon half 10 need only be fixed with one hem tape 15a, the peripheral edge portions 15 can be made bulky. Therefore, like a normal pine tress, the cross-sectional shape becomes a flat rectangle, and the hard cotton 1
By arranging 1b, the overall size of the futon does not change, so the width can be used as wide as possible.

Furthermore, quilting 1 is added to the futon half 10.
4 is applied and the hard cotton 11b is housed, so it has excellent shape retention and prevents the cotton from bunching or cutting. In addition, this mattress is made by stacking two futon halves 10 with quilting 14, so it is about twice as bulky as a regular quilted futon, and it retains heat. It has excellent protection against heat and external air.

As explained above, this idea involves making the insole of two futon halves face each other, and fixing the periphery of the two futon halves through a belt-like gusset of the required width made of flocked fabric. Since the duvet is made of hard cotton and is integrally formed, it has sufficient bulk, and an air layer is formed between the two layers, and even when quilted, the overall size of the duvet does not become smaller. Good shape retention. In addition, since an air layer is formed, it has excellent heat retention and insulation against outside air, and dries quickly.Furthermore, the half of the futon is quilted, so even after long-term use, the cotton will not bunch or break. It has the advantage that such problems do not occur.
