DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to clothing and bedding incorporating downs, and more particularly, to the prevention of protrusion of a stalk and leakage of a barb, and also saves the amount of downs used without impairing heat insulation. The present invention relates to a down inclusion and a method of manufacturing the same.

[0002]

2. Description of the Related Art As a heat insulating material used for clothing for winterization, down is considered to be the most excellent because of its lightness and heat insulating property. Here, “down” means, in a narrow sense, the chest and feathers of a waterfowl such as a goose or a duck, but in a broad sense, is a concept including small feathers. FIG.
(A) is the down 3 in a narrow sense composed of the wing shaft 31 and the barb 32.
FIG. 8B illustrates a small feather 30b including a blade shaft 31 and a barb 32. FIG. By the way, the down jacket as shown in FIG. 9 is a mixture of down and small feather in a narrow sense,
It has a cross-sectional structure as shown in FIG. That is,
The down 30 is accommodated in the high-density bag fabrics 33a and 33b, and the outer fabric 34 is provided outside the high-density bag fabrics 33a and 33b.
And a backing material 35 are provided.

[0003]

However, the down has the following problems due to its lightness and easy floating, and the down also contains small feathers. . First, the feather shaft 31 of the small feather may pierce through the high-density bag fabrics 33a and 33b and fly out, which may significantly impair the commercial value. The quill 31 is made of, for example, a high-density bag cloth 33.
a, and the back cloth 3 or the back cloth 3
5 may cause unevenness due to wrinkles 34a and 35a, which is also a problem. On the other hand, the down 30 is wrapped in high-density bag fabrics 33a and 33b to prevent leakage of the barb 32 separated from the blade shaft 31, but the barb 32 and the blade are still passed through the needle hole 38 of the stitch 37. There was a problem that the shaft 31 leaked. Here, in order to prevent leakage of the barb 32 and the like, it is conceivable that the stitch 37 is not provided. However, when the stitch 37 is not provided, the surface of the high-density bag fabric 33 is smooth,
There is a problem that the down 36 is shifted downward. The present invention has been made in view of these problems, and can reliably prevent down leakage.
An object of the present invention is to provide a down inclusion that does not cause unevenness due to wrinkles.

[0004]

In order to achieve the above object, according to the first aspect of the present invention, the cloth after sewing, the first inner bag and the second inner bag are separated into three pieces. After superimposing the layers, a step of welding or heat-sealing the peripheral portions of the three layers except for the part of the injection port to integrate them, and blowing a predetermined amount of down through the injection port, Wherein the first and second inner bags are made of cotton or synthetic fabric. The invention according to claim 3 is characterized in that, after the sewn-up outer fabric, the first inner bag cotton and the second inner bag cotton are overlaid in three layers, the three layers except for the injection port are overlapped. A first step of welding or heat-sealing the peripheral portions of the first and second parts, and a second step of sewing and closing the injection port after blowing a predetermined amount of down through the injection port. 2. The inner bag cotton is made of cotton or synthetic cotton. INDUSTRIAL APPLICABILITY The present invention balances the characteristics of the cotton with the heat retaining property of down, and can prevent leakage of the barb and can produce excellent products in which wrinkles due to the blade shaft are eliminated. In both of the first and third aspects of the invention, as the inner bag, processed cotton having a laminated film layer provided on the surface of the synthetic fiber can be used, and in this case, a product further excellent in heat insulation and waterproofness. Can be provided. The down inclusions are typically clothing for cold weather, but also include daily necessities such as duvets and sharafuzaks.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in more detail by taking a case of manufacturing a down jacket as an example. The sewn outer fabric 1, the first inner bag 2a, and the second
After the inner bag 2b is overlapped with the three layers, the peripheral part 4 of the three layers is sewn together except for the portion of the injection port 3 to integrate the whole. FIG. 1 shows the back body after sewing the inner bags 2a and 2b, but the middle bags 2a and 2b are sewn in the same manner for the front body and the sleeves. Cotton cotton can be used for the inner bag cotton 2a, 2b,
It is not necessary to be limited to this, but synthetic fibers may be used. And when synthetic fiber is used, since the surface cloth 1 of synthetic fiber and the synthetic bag inner cloth 2a, 2b can be heat-sealed using high frequency heat, work efficiency increases. When the outer cloth 1 and the inner bag 2a, 2b are integrated, a predetermined amount of down is put between the first and second inner bags 2a, 2b with the injection port 3 upward. Inhale. FIG.
Fig. 3 illustrates this working state, in which the injection pipe 5 is inserted from the injection port 3, and the down is uniformly injected while the injection pipe 5 is appropriately moved. After a predetermined amount of down is injected, the injection opening 3 is sewn and closed, thereby completing the down-filled batting. FIG. 3 illustrates a cross-sectional structure of the down-filled batting, and shows a peripheral portion of a four-layer structure including a surface cloth 1, a first inner bag 2a, a down 6, and a second inner bag 2b. 4 shows a state in which they are completely met. When the down-filling batting is completed, next, the front stitch 7 is provided if necessary, and finally, the backing fabric 8 is sewn (see FIG. 4). By assembling the front body, the back body, and the sleeve body thus completed, a down jacket as shown in FIG. 9 is completed.

[0006] In the down jacket manufactured as described above, the down 6 is accommodated in the inner bags 2a and 2b. Therefore, depending on the entanglement of cotton and synthetic fibers and the thickness thereof, the down shaft is provided. Since the hardness of 6A is absorbed, wrinkles do not occur on the front fabric 1 and the back fabric 8. In addition, even if the stitch 7 is put in the table cloth 1,
Since the needle hole 9 of the inner bag 2 is closed by the elasticity of the cotton or the synthetic fiber, the down barb 6B and the like do not leak. Further, since the down 6 has a property of being caught and entangled with cotton or synthetic cotton, if the amount of down used is not so large, the down will not be offset downward without providing the partition stitch 7. FIG. 5 shows a sectional structure in a state where the partition stitch 7 is not provided. It should be noted that cotton and synthetic cotton have higher air permeability than high-density fibers, and therefore there is no risk of causing unevenness. Further, although the amount of down use can be saved by the amount of the inner bags 2a and 2b, even if the amount of down use is reduced, the heat retention is not impaired.

The case where cotton or synthetic fiber is used has been described above. However, laminated cotton having a two-layer structure shown in FIG. 6 may be used as the inner bags 2a and 2b. This laminated cotton is obtained by laminating a film 21 such as urethane on the surface of a synthetic fiber cotton 20.
Are provided with fine ventilation holes that allow gas to pass through but prevent water from passing through. The use of such laminated cotton makes it possible to more reliably prevent the blade shaft from penetrating or wrinkling, regardless of the quality or amount of the down. In addition, heat retention and waterproofness can be further improved without impairing air permeability. Furthermore, even if a front stitch is provided due to design requirements, the needle hole 9 is closed by the elasticity of the film 21, so that the down barb 6B does not leak. In addition, two middle bag cotton 2a, 2b,
Since the polymer is polymerized in the illustrated direction, the cold feeling of the film 21 is not transmitted to the body 10.

When no partition stitch is provided, FIG.
As shown in (a), the net-like sheet 11 may be overlapped between the inner bags 2a and 2b. Then, a down 6 is blown between the inner bag 2a and the mesh sheet 11. According to this configuration, the down 6 is made of synthetic fiber cotton 20 of the inner bag 2a.
And the mesh sheet 11 are well entangled with each other, so that the down 6 can be more effectively prevented from shifting downward. The material of the mesh sheet 11 is not particularly limited, but it is preferable to select a material having good elasticity because it can cope with the movement of the body 10.

[0009]

As described above, according to the present invention, since the down is wrapped with the inner bag made of cotton or synthetic fiber, the following excellent effects are exhibited. Since the inner bag cotton serves as a cushion and can prevent protrusion and wrinkling of the wing shaft, it is possible to realize soft clothing having a smooth appearance. Since the down is caught on the inner bag and entangled, the down can be prevented from being biased without providing a partition stitch. On the other hand, even if stitches are provided on the outer fabric due to design requirements, the needle holes are closed by the elasticity of the fibers, so that there is no danger that the barb will leak from the seam holes. Since it is not necessary to use a high-density woven fabric as in the related art, it is possible to realize clothing and bedding with better breathability than in the related art. Since cotton or synthetic cotton is used, the amount of down used can be saved by that much, and even in this case, the heat retaining effect is not impaired by the characteristics of the cotton and down. Since the down consumption can be reduced in this way, it is possible to suppress the overfishing of rare water birds,
It can also contribute to nature conservation. In the past, the weaving density of the outer fabric was limited to prevent the protrusion of the wing shaft, but in the present invention, since the leakage of feathers and the like can be completely prevented by the inner bag, There are no restrictions. When synthetic fiber is used for the inner bag cotton, high-frequency heat fusion can be used, so that work efficiency is improved.
