[0011]

[Embodiment of the invention]

 FIG. 1 is a schematic cross-sectional view showing an example of a cloth according to the present invention. The cloth 10 includes a front cloth 12. The outer cloth 12 is formed of, for example, a soft mesh cloth formed of acrylic synthetic fiber.

The front fabric 12 is formed on the surface side of the high-foaming polyethylene sheet layer 14 to be described later so as to protect it from being easily torn. Therefore, it is preferable to use a fibrous body, particularly a woven fabric, in which fibers are formed in at least two directions so as not to be easily torn in one direction. In this example, the outer fabric 12 is formed of a mesh-like fabric formed by weaving a thread made of acrylic synthetic fiber, but is not limited to this, and other synthetic fibers, hemp, cotton, etc. It may be formed from a cloth made of natural fibers or the like, or a non-woven fabric made of various materials.

When the cloth 10 is desired to have high waterproofness, the surface cloth 12 is coated with a synthetic resin so as to prevent water from entering due to the texture of the cloth 12. Is preferred.

A high-foaming polyethylene sheet layer 14 is formed below the surface fabric 12. The high-foaming polyethylene sheet layer 14 is formed of a high-foaming polyethylene sheet 14a having a thickness of about 1 mm, each of which is provided with fine air bubbles independently formed.

The highly foamed polyethylene sheet 14a is formed into a sheet-like body by heating a raw material in which a foaming agent such as polyethylene and butane is mixed to cause foaming. At this time, the high-foaming polyethylene sheet 14a has fine bubbles formed independently of each other without forming bubbles in a continuous manner.

As described above, the high-foaming polyethylene sheet 14a formed by foaming is formed so that the weight ratio of polyethylene is 97% or more and the residual butane is 3% or less. As a result, the high-expansion polyethylene sheet 14a has an apparent density of 0.06 to 0.015 g / cm ³ and is extremely lightweight, and has a thermal conductivity of 0.035 to 0.040 Kcal / m · hr · ° C. And the heat insulation is very high.

A cushion material 16 is formed under the high-foam polyethylene sheet layer 14. In the example shown in FIG. 1, the cushion material 16 is formed of feathers such as down and feathers.

The cushion material 16 is formed so as to absorb the external force by being deformed when the cloth 10 receives the external force. However, it is not preferable to use a material that is plastically deformed when an external force is applied, because the appearance of products such as clothing and ornaments is deteriorated. Therefore, the material used for the cushion material 16 is made of feather or cotton made of various materials, which has many fine spaces for holding the outside air, is highly flexible, and can be easily restored in shape. Is preferred.

The high-foaming polyethylene sheet layer 14 described above is further laminated on the lower layer of the cushion material 16. As a result, it is possible to form the fabric 10 having higher waterproofness, heat retention and buoyancy.

Further, a backing material 18 is laminated under the high-foaming polyethylene sheet layer 14.

The backing fabric 18 is made of a material having the same properties as the front fabric 12. This is to prevent the high-foamed polyethylene sheet layer 14 laminated on the upper layer of the backing fabric 18 from easily tearing, and is formed for the same purpose as the front fabric 12.

In the cloth 10 shown in FIG. 1, the cloth 10 is made by stacking two layers of the high-foaming polyethylene sheet layer 14 and one cushion material 16 between the front cloth 12 and the back cloth 18. Although formed, the present invention is not limited to this, and several high-foam polyethylene sheet layers 14 and cushion materials 16 may be further laminated in accordance with desired waterproofness, heat retention and buoyancy.

FIG. 2 is a perspective view showing a life jacket 50 made by using the fabric 10 according to the present invention, and FIG. 3 is a sectional view taken along line III-III shown in FIG. The life jacket 50 is made by using the cloth 10 shown in FIG. 1, but as shown in FIG. 3, the life jacket 50 is appropriately directed in the thickness direction of the cloth 10, that is, from the front cloth 12 to the back cloth 18. Then, the welded portions 20 are formed by welding the layers forming the dough 10 and welded in a block shape.

As a result, the cushion material 16 laminated between the front cloth 12 and the back cloth 18 is held by the welding portion 20, moved by vigorous motion or gravity, and is positioned in a specific portion. You can prevent that. As a result, it is possible to prevent variations in heat retention and buffering between parts of the product.

Since the life jacket 50 is made of the fabric 10, it is extremely lightweight and has sufficient buoyancy and high heat retention. Therefore, the wearer should not be tired even when wearing the life jacket 50 for a long time in preparation for an accident, etc., and prevent the body temperature from decreasing even if he / she falls into the water. You can

FIG. 4 is a sectional view showing another example of the cloth according to the present invention. The fabric 30 of this example is different from the example shown in FIG. 1 in that the order of the high-foaming polyethylene sheet layer 14 and the cushioning material 16 laminated between the front fabric 12 and the back fabric 18 is different from that of the example of FIG. A cushion material 16 is laminated on the lower layer of 12.

In the case of stacking as in the example of FIG. 4, the cushion material 16 absorbs moisture, water and the like generated inside the cloth 30 through the back cloth 18. As a result, even when the wearer makes a lot of sweat due to heavy exercise or the like, water drops do not easily adhere to the clothes and the wearer does not feel uncomfortable.

In this example, since the cushion material 16 located in the upper layer is laminated near the surface layer of the cloth 30, the cushion material 16 is more likely to contain water. Therefore, when high waterproofness is desired for the fabric 30, it is desirable that the outer fabric 12 be formed of a material having waterproofness.

In order to use the cloth 30 as a surface cloth for clothes or the like, it is preferable to use a material having a water-repellent property for the surface cloth 12, but the cloth 30 is used as a filling material such as clothes, that is, This does not apply when the product is used so that it is sandwiched between the front and back fabrics.

FIG. 5 is a sectional view showing another example of the present invention. In the dough 40 shown in FIG. 5, the powdered polyethylene is evenly dispersed on the back surface of the front dough 12, and the powdered polyethylene is heated and melted, so that the high-foaming polyethylene sheet 14a laminated thereon is welded. Then it is laminated. That is, the cloth 40 is a cloth composed of the surface cloth 12, the adhesive layer 22 formed by dissolving the powdered polyethylene, and the high-foaming polyethylene sheet layer 14.

Since each layer of the dough 40 is welded over the entire surface, processing can be made very easy. Further, since the high-foaming polyethylene sheet layer 14 is used, it has the same high heat retention and waterproof properties as the fabric 10 described above.

In this example, the adhesive layer 22 is formed by dissolving the powdered polyethylene, and the surface material 12 and the high-foaming polyethylene sheet layer 14 are welded and laminated to each other. The means for laminating 12 and the high-foaming polyethylene sheet layer 14 is not limited to this.

For example, the material forming the adhesive layer 22 is not limited to polyethylene, and a powder synthetic resin having good weldability to both the surface material 12 and the highly expanded polyethylene sheet layer 14 is used. Then, the surface material 12 and the high-foaming polyethylene sheet layer 14 may be welded by the above-mentioned method and laminated.

The material forming the adhesive layer 22 is not limited to a powdery material, and a synthetic resin having good weldability with respect to both the surface material 12 and the high-foaming polyethylene sheet layer 14. It is also possible that the above film is laminated on the back surface of the front fabric 12, and this film is heated and melted to fuse and laminate the high-foaming polyethylene sheet layer 14 overlaid thereon.

Further, a synthetic resin having a favorable weldability is melted into both the outer fabric 12 and the high-foaming polyethylene sheet layer 14 and extruded in a film form on the back surface of the outer fabric 12. Alternatively, the high-foaming polyethylene sheet layer 14 may be laminated and laminated on the surface thereof by welding.

Furthermore, an adhesive having good adhesiveness is used for both the front fabric 12 and the high-foaming polyethylene sheet layer 14 to simply attach the front fabric 12 and the high-foaming polyethylene sheet layer 14 to each other. It may be laminated by adhering.
