Description

[Detailed explanation of the idea] This invention relates to futons.

In more detail, it is a futon whose filling is made of continuous filament yarn, which effectively prevents the ends of the continuous filament yarn constituting the filament cotton from coming out from the side fabric. This is about a futon that has been used for a long time.

Traditionally, futon cotton made of stable (short fibers) is well known, but it has the disadvantage that the futon cotton (short fibers) comes out from the side of the futon, and in order to improve this, , special processing is applied to the side of the futon,
Alternatively, the side fabric density and basis weight have been increased, the fibers used have been made into composite fibers, or resins have been applied.

However, these methods not only have the drawbacks of significantly impairing the feel and feel of the futon and increasing costs, but they also cannot completely prevent cotton from coming off. .

On the other hand, cotton padding materials using continuous long filament yarns have been used and developed for stable futon cotton, but although they are cheaper in cost (HS), they have problems with texture (H3) and the cotton shedding mentioned above. Although it is not as frequent and severe as when using a table, it still has the same drawback that the cut end of the filament comes off, and in this case, one continuous long filament thread is pulled out as a whole. However, the frequency of cotton removal was at least significant, and the quality of the product was significantly lowered.

In order to prevent this drawback, methods are known in which the entire filament cotton material is treated with resin, or the cut ends of the filament are treated with cotton and welded together, but both of these methods do not provide enough softness to be used as a futon. The current situation is that IS is not a desirable solution because it impairs the H3 texture and hardens the texture.

Furthermore, as a conventional example, there is also known a futon which is folded in the thickness direction using a tow, as disclosed in Japanese Patent Publication No. 46-21263.

However, the futon obtained by this method has a relatively hard feel, and the futon of the apparatus is high, so this method is not satisfactory.

The purpose of the present invention is to improve the problem of cotton shedding in the prior art, and to provide a new futon made of continuous filament yarn that is inexpensive and has less deterioration in feel.

This purpose is to provide a futon in which a large number of continuous long filament yarns form a fibrous layer to constitute the filling, and the cotton is covered on the side fabric, and the continuous long filament yarns are arranged in a plane direction of the futon. The fibers are arranged diagonally with respect to the longitudinal direction, and form a plurality of fiber layers in the thickness direction of the futon, and the fiber ends of the continuous filament yarns are arranged in a non-contact state with the side fabric. A futon characterized by being folded into the inside of a futon (hence its distant cousin).

Hereinafter, the futon of the present invention will be explained in more detail.

The continuous long filament yarn used in the futon of the present invention may be made of any material, but polyester synthetic fibers are effective because they have excellent resistance to sagging.

The number (denier) and number of continuous filament yarns are '
%l is limited, and it is possible to use tow-shaped fibers, fibers that have been opened into a bulky shape, and fibers that have been roughly crimped. Shaped products can also be used.

In the futon of the present invention, a large number of continuous long filament yarns form a plurality of fiber layers to constitute the filling, and the fiber layers are arranged so that the fiber end force of the continuous long filament yarns does not come into contact with the side material. It is folded in and covered from the side.

Such a structure will be explained using the drawings.

FIGS. 2 to 6 are schematic diagrams showing various embodiments of the futon of the present invention and showing cross sections in the longitudinal direction of the futon.

As can be seen from these figures, the futon of the present invention is made by appropriately folding the fiber layers 1 and 1' to prevent them from coming into contact with the fabric 2 and the cut end force 3 of the continuous filament yarn.

As an example of a futon, FIGS. 2 to 4 show an example of a futon having substantially four fiber layers.

The embodiment shown in FIG. 3 is D, which is obtained by additionally using a sheet material 3 such as a non-woven fabric in addition to the embodiment shown in FIG. 2.

In this way, the futon of the present invention can have various aspects.
3. The important point is that the fiber layer is folded in such a way that the cut end of the continuous filament yarn does not come into contact with the side fabric.

Note that FIG. 1 shows a comparative example of the present invention, in which the fiber layer is one layer.

A single fiber layer is not preferable because the folded portion becomes abnormally thick and lacks uniformity.

Such breather layer] can be improved by rubbing and becomes preferable.

Also, in Figures 2 to 4, the direction of the fibers is shown to be mostly parallel to the longitudinal direction of the futon, but in reality, the direction of the fibers is parallel to the longitudinal direction of the futon. As shown in Fig. 6, it is oblique.

That is, as shown in the model in FIG. 5, the continuous fiber web is traversed diagonally in the longitudinal direction A of the futon in the direction of arrow B to form a fiber layer.

In such a case, after forming one long diagonal fiber layer, fold multiple layers of the fiber layer as appropriate, and then fold in the vicinity of the end of the fiber layer as appropriate so that the cut end of the filament does not come into contact with the side material. You can fold the futon as per the finished dimensions of the futon, or you can finish the futon at the same time as the diagonal arrangement, taking into account the folding allowance near the end of the fiber layer, that is, the diagonal arrangement several times. It is also possible to form a plurality of fiber layers by reciprocating by a distance other than the dimension, and then fold the folding margin.

When the continuous long filament system is arranged diagonally in this way, line deviation can be prevented also because the long filament system force S is arranged obliquely, which is compatible with the above-mentioned effect of folding. However, the line method provides a futon with a great prevention effect.

In addition, since the filling is integrated, the futon also has the advantage of good shape stability.

In this case, even if the end of one futon is not folded over the entire area as shown in FIG. 1, it is folded in only a single web end of the traversed continuous fiber web as shown in FIG. It goes without saying that the configuration shown in section C in FIG. 6 may also be used.

In the futon 1 of the present invention, the end surfaces of the continuous long filament yarns may of course be subjected to line bonding or resin processing before folding.

When used in combination with the fusing bonding and resin processing, the futon line method of the present invention will have an even greater prevention effect, and the folding workability will also be significantly improved.

Furthermore, the fact that the melted/adhesive part or the resin-processed part is folded in so that it does not come into contact with the side fabric means that the part has been treated to prevent it from coming into contact with the human body. As a result, this part hardly gives the user a feeling of roughness or discomfort.

As described above, the futon of the present invention has a simple structure, can significantly prevent the inconvenience of cotton shedding, which was conventionally desired to be solved, and is extremely useful without deteriorating the feel, feel, etc.

Moreover, manufacturing cost can also be made extremely low.
