Abstract

PURPOSE:To prevent this double cloth from swelling round even when filled with fluid and swell flat to enable the cloths to stack up, by jointing the upper cloth with the lower cloth, which are superimposed on each other at a predeter mined interval, by mean of pile threads to form a double-piled cloth and closing the texture of the upper and lower cloths. CONSTITUTION:The upper cloth 11 and the lower cloth 12 superimposed in each other at a predetermined interval H are mutually joined by pile threads 13 to form a double-piled cloth structure. The texture of the upper cloth 11 and the lower cloth 12 are closed to fill with a fluid the space 20 between the upper cloth 11 and the lower cloth 12. The peripheral edge 16 is sewed to form a shaped seat (cushion material) 22. In this way, this double-cloth 15 made of the upper cloth and the lower cloth is useful for a bag 18 material holding a fluid and a super-ficial member or a rear face member of a molding 22 made from a solidified fluid and also it is preferable when producing a fluid-ejector.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double cloth used as a container or bag for filling and storing a fluid such as gas or liquid.

[0002]

2. Description of the Related Art A bag filled with a fluid is constructed by stitching the peripheral edges of a non-breathable sheet which is vertically laminated and doubled. In this type of conventional bag, the inside of the sewn rim is a continuous cavity from the rim to the rim, and the fluid filled in the cavity can move freely, and the bag itself can be folded to make it optional. Since it is a flexible one that can be deformed to the shape of, the whole bag bulges round when full of fluid is filled, the short bag with a shallow bottom deforms to a shape close to a sphere, and the bag with a deep bottom has a pillar shape. It transforms into a shape close to the shape,
In addition, when the amount of fluid to be filled is small, the fluid is deformed into various shapes.

[0003]

A bag that is filled with a fluid and bulged in a round shape cannot be stacked high because a load collapse easily occurs. It requires a large space in its storage warehouse and is easy to transport by truck. Always carries the risk of collapse. Therefore, the present invention is intended to provide a bag that does not bulge in a round shape even if it is filled with a fluid, and bulges flat and can be stacked high.

[0004]

Double cloth 15 according to the present invention
Can be made into a bag only by closing the peripheral edge 16, and the upper cloth 11 and the lower cloth 12 that are overlapped with each other at a constant interval H are connected by a pile thread 13 to form a double pile cloth original fabric structure. It is characterized in that the upper cloth 11 and the lower cloth 12 are configured so as to close the mesh. Double cloth 1 like that
To make No. 5 a double pile fabric original structure, the upper cloth 11 and the lower cloth 12 are simultaneously woven in upper and lower layers by a loom or knitting machine such as a double moquette loom, a double Wilton loom, a double Rasiel warp knitting machine, or the like. In the process of knitting, the pile thread 13 is woven or knitted into the upper cloth 11 and the lower cloth 12, and the pile thread 13 to be woven or knitted is transferred between the upper cloth 11 and the lower cloth 12 to form the upper cloth 11 and the lower cloth 12. Just connect.

Conventionally, in such a double pile fabric original fabric, the pile thread 13 is then cut between the upper cloth 11 and the lower cloth 12 to separate the upper cloth 11 and the lower cloth 12, and the cut surface is the pile surface. Is known as an intermediate product for producing carpets and moquettes of cut pile fabric. The cut pile fabric thus cut off is coated with a necessary backing adhesive for backing, and at that time, a required secondary base fabric is laminated to be finished into a carpet or a moquette.
Depending on the backing adhesive used for backing and the secondary base cloth, a non-breathable, water-impermeable carpet or moquette can be obtained. Since it is performed after separating it from the upper cloth 11 and the lower cloth 12, the raw material of the double pile cloth before the separation has air permeability and water permeability, and the fluid is filled between the upper cloth 11 and the lower cloth 12. I can't do that.

The present invention relates to a double pile fabric stock, which is conventionally woven and knitted as an intermediate product of carpets and moquettes,
It is intended to be used as a material of a bag 18 for filling a fluid, and the space of the upper cloth 11 and the lower cloth 12 can be filled with the fluid by closing the grain of the upper cloth 11 and the lower cloth 12 thereof. To do. In order to close the texture of the upper cloth 11 and the lower cloth 12 of the double pile fabric original fabric, a fluid composition having a caking property is applied to the front and back of the double pile fabric original fabric, or a non-breathable / water impermeable sheet or It is preferable to laminate the non-breathable / water-impermeable layer 25 by laminating the plates. In that case, as the fluid composition having a caking property, cement or gypsum, an inorganic adhesive such as clay or an organic adhesive such as a plastic paste or latex, or as a non-breathable / water-impermeable sheet or plate. Plastic films, rubber sheets, plywood, metal plates, etc. are used.

The double cloth 15 is cut into a desired size, and the upper cloth 11 and the lower cloth 12 are sewn together at the peripheral edge 16, or the patch cloth 21 is sewn to the peripheral edge 16 or the like. It is used by filling a space between the upper cloth 11 and the lower cloth 12 with a fluid by closing the gap of the peripheral edge 16 of the bag to make a bag 18. In that case, it is possible to fill the space 20 between the upper cloth 11 and the lower cloth 12 with the fluid and then sew the peripheral edge 16, or
In some cases, the peripheral edge 16 may be left unsewn. For example, in a fluid such as an electromagnetic wave curable resin composition or a vinyl chloride paste sol which can be solidified by irradiation with electromagnetic waves, heating or other means after filling the space 20, the space between the upper cloth 11 and the lower cloth 12 should be 20. It is also possible to obtain a cushioning material or other molded article 22 by filling the upper cloth 11 and the lower cloth 12 with each other at the peripheral edge 16 of the double cloth 15 when the fluid is filled. Stitching is not always required. As described above, the double cloth 15 according to the present invention can be used as the surface material and the back surface material of the molded product 22 formed by filling the space 20 with the solidifying fluid. Set the heavy cloth 15 in the cavity of the molding die and molding frame that form the required three-dimensional structure,
By filling the double cloth 15 in the set cavity with the fluid, a molded product 22 having a complicated three-dimensional structure in which the double cloth 15 and the fluid are integrated is obtained.

In order to facilitate the diffusion of the fluid thus filled between the upper cloth 11 and the lower cloth 12, the distance S between the pile yarn 13 in both the warp direction (S) and the weft direction (G) is set. It is recommended that both G be 2 cm or more. This pile thread 13
The spacing S and G of may be partially changed,
In order to partially change the spacing S and G between the pile yarns 13 as described above, the pile yarns 13 are arranged at regular intervals in the weaving / knitting process of the double pile fabric original structure.
The upper cloth 11 and the lower cloth 12 are transferred by connecting the upper cloth 11 and the lower cloth 12 together, and the pile yarn 13 is long together with the ground warp 23 forming the upper cloth 11 and the lower cloth 12 for a certain interval until the upper cloth 11 and the lower cloth 12 are changed. The weave / knit structure of the lower cloth 12 may be configured. In that case, the arrangement density of the pile yarns is changed so that the interval between the pile yarns adjacent to each other at a constant interval G of 2 cm or more becomes about 1 to 5 cm, or the pile yarns are adjacent to each other with a constant interval S of 2 cm or more. The pile yarns are moved between the upper cloth and the lower cloth so as to closely match the pile yarns by about 1 to 5 cm, and the pile yarns are closely bonded to each other, so that the distances S and G between the pile yarns are both partially changed. You can also do it.

The densities of the warp and weft of the woven / knitted fabric structure of the upper cloth 11 and the lower cloth 12 and the density of the stitches depend on the strength of the coating film of the adhesive that closes the cloth and the non-breathing / water-impermeable properties to be laminated. It is appropriately set in consideration of the adhesive strength with the sheet or plate. Top cloth 1
The distance H between the lower cloth 1 and the lower cloth 12 is the double cloth 15 filled with the fluid.
Is appropriately set according to the use of, for example, when filling and storing gas or liquid, or when making a cushion material such as an air mat, a water bed, or a water pillow, the interval H may be set to 5 to 20 cm, When the fluid is solidified to form the molded product 22 having a thickness of 1 to 5 cm, the thickness is set to 1 to 5 cm according to the thickness. When a cushioning material such as an air mat or a water bed is formed, or when a fluidized product is solidified to form a molded product 22, those products (18
・ In order to change the design and physical properties of the front and back of 22), the upper cloth 11
It is also possible to change the color and thickness of the ground warp yarn 23 and the ground weft yarn 24 of the lower cloth 12, the fiber material, the weaving / knitting density, and the weaving / knitting fabric structure.

In the double cloth 15 according to the present invention, the gap between the upper cloth 11 and the lower cloth 12 at the periphery thereof is closed with a pad cloth 21 or the like, and then the upper cloth 11 or the lower cloth 12 is passed through a large number of passages. Pore 2
6, the gas or liquid sent into the internal space 20 by the blower is ejected from the vent hole 26 to form an air table, a wall ventilation device, a bubble ejection device in a bathtub, a bubble generation device,
It is also possible to form a fluid ejection device such as a fountain device.

[0011]

In the double cloth 15 of the present invention, the upper cloth 11 and the lower cloth 12 are bonded to each other by the pile yarns 13 on the entire surface thereof, so that a large amount of fluid is filled between the upper cloth 11 and the lower cloth 12. It does not swell in a round shape even when filled, and the upper cloth 11 and the lower cloth 12 are connected to the pile yarns 13 that are connected to each other so that the pile cloth 13 is kept in a parallel state. Since it becomes a thick plate, it is difficult to collapse the load even if it is piled up high, and therefore, it is possible to store the fluid by stacking it in a cubic shape instead of a pyramid shape, and by doing so, it can be stored in a truck or the like. The load capacity can be increased and space can be effectively used in the storage warehouse.

The internal pressure of the double cloth 15 generated when the fluid is fully filled in this way is
Of the pile yarns 13 distributed over the entire surface of the
Since the pile threads 13 are woven into the upper cloth 11 and the lower cloth 12 to form a part of the woven / knitted fabric structure of the upper cloth 11 and the lower cloth 12, the internal pressure acting on each pile thread is Then, the upper cloth 11 and the lower cloth 12 are dispersed in the ground warp 23 and the ground weft 24 and absorbed by the upper cloth 11 and the lower cloth 12. Therefore, the pile thread 13 is not cut and the upper cloth 11 and the lower cloth 12 are not broken, and the double cloth 15 filled with the fluid is provided.
The packaging of is maintained as a flat plate.

Further, according to the present invention, a molded article 22 in which the filled fluid is solidified and the front and back are covered with the fabrics 11 and 12
It is also possible to obtain a molded product 22 thus obtained
Since the front and back are connected by pile threads 13, it is possible to obtain a molded product 22 having a stable shape and excellent strength, even if the fluid temporarily solidifies softly like gelatin or agar. I can.

As described above, the double cloth 15 according to the present invention is used as a material for the bag 18 filled with the fluid, as a surface material or a back material of the molded product 22 formed by solidifying the fluid, and as a fluid material. This is a great advantage in manufacturing a body ejection device.
