とが示されている。2. Description of the Related Art A porous moisture-permeable waterproof membrane is laminated with a synthetic fiber cloth to form a moisture-permeable waterproof sheet material, and a three-dimensional molding technique using this material is, for example, Shoukaisho 63-606.
There is one described in Japanese Patent No. 25. According to this publication, a hat with less seams can be manufactured by three-dimensionally processing the moisture-permeable waterproof sheet, and it is possible to provide an inexpensive moisture-permeable waterproof molded article that does not require seam processing when a three-dimensional body is formed by sewing. It is shown.

ートが有していた透湿性を維持できない。However, since the moisture-permeable and waterproof sheet is a laminate of a porous sheet and a synthetic fiber cloth, the porous structure is deformed by stretching during three-dimensional molding, and the sheet has a transparent property before molding. Cannot maintain wetness.

制約を受ける。Since it is a porous body, its strength per thickness is naturally weaker than that of a solid body made of the same material.
Material will be destroyed due to excessive deformation. In other words, only elongation deformation that does not cause material destruction can be performed, and processing (mold) is restricted.

い。The hat material used in the present invention is a cloth in which a non-porous moisture-permeable and waterproof polyurethane film is laminated on the surface of a knitted fabric as shown in FIG. In the figure, 1 indicates a knitted fabric, and 2 indicates a non-porous moisture-permeable waterproof polyurethane membrane. The knitted fabric used in the present invention is a general nylon, a knitted fabric made of synthetic fiber such as polyester, or a stretch knit containing elastic fibers such as spunbond yarn. Examples of such a knitted fabric include a circular knit, Warp knit, plain knit,
Examples thereof include tricot knit and tricot half knit. The thread thickness of this knitted fabric is 1 to 70 denier, preferably 5 to 40 denier. The thickness of the knitted fabric is 0.05 to 1.0 mm, preferably 0.1 to 0.5
mm. The non-porous moisture-permeable and waterproof polyurethane membrane is conventionally known, and has a molecular weight of 500 to 3000, for example.
Polyoxyethylene content of 15 to 6 by the reaction polymer of polyether polyol and organic polyisocyanate of
It can be obtained by forming 2% of polyurethane polymer into a film. This polyurethane film has an elongation of 50% or more, preferably 100% or more and a tensile strength of 10%.
0 kg / cm 2 or more, preferably 150 kg / cm 2 or more, thickness 5 to 100 μm, preferably 10 to 100 μm
It is preferable to use those having physical properties of m and moisture permeability of 8000 g / m 2 · 24 hr or more. Such a polyurethane film is non-porous, has flexibility, is highly stretchable, and has excellent moisture permeation and waterproof properties. If the thickness of the polyurethane film is less than 5 μm, the material breaks during three-dimensional molding, and if it is more than 100 μm, the moisture permeability deteriorates. Also, the elongation is 50% or more and the tensile strength is 100 kg /
If it is at least cm 2 , the film will not be broken during stretching.

せず有効である。The porous moisture-permeable waterproof membrane used in the prior art has a porous structure that allows water vapor to pass therethrough. When these materials are stretched, the porous structure is stretched and the pores are collapsed, so that the pores through which water vapor permeates are substantially eliminated and the moisture permeability decreases. On the other hand, the non-porous moisture-permeable waterproof membrane has a moisture-permeable mechanism of "dissolution of water molecules into the membrane-diffusion in the thickness direction-evaporation from the surface opposite to the membrane", so that the material is extended by stretching When it is blown out, it may be thin, the diffusion distance of water molecules may be short, and the moisture permeability may be high, but it is not low. As described above, it is effective to use the non-porous moisture-permeable waterproof membrane for a three-dimensional molded article without impairing the properties of the material before processing.

ない。In the laminate of the knitted fabric and the polyurethane film, a part of the polyurethane film penetrates into the knitted fabric, but in the present invention, the thickness of the polyurethane film on the knitted fabric surface is 5 to 100 μm, preferably 10 to 10
It must be 0 μm thick. If the thickness of the knitted surface of the polyurethane film is less than 5 μm, the breaking elongation is reduced to 50% or less, and three-dimensional molding becomes impossible. On the other hand, according to the present invention, when the thickness of the polyurethane film on the knitted surface is set to 5 μm or more, preferably 10 μm or more as described above, the breaking elongation is also 50.
% Or more, the polyurethane film is not broken during the three-dimensional molding and the three-dimensional molded product can be easily processed. Further, in the laminate of the knitted fabric and the polyurethane film, since the knitted fabric originally has stretchability due to its stitch structure, the laminate laminated with the polyurethane film having the above properties also has the stretch ratio of 50% or more. Those that do not have an elongation rate of 50% or more are not practical as hats with few seams from the viewpoint of three-dimensional molding.

In addition to the heat fusion method, an adhesive method using an adhesive can be used. In this case, conventionally known adhesives, for example, urethane-based, nylon-based, ester-based, etc. adhesives can be used. Further, as the adhesive application device, a spray device or a gravure roll can be used. The adhesion area between the non-stretchable knitted fabric and the polyurethane film is
It is good to set it in the range of 5 to 90%, preferably 10 to 50% of the total contact area. As for the positional relationship between the knitted fabric and the polyurethane film, the polyurethane film may be positioned on either the inner side or the outer side of the hat.

A structure in which the knitted fabrics 1 and 3 are laminated on both surfaces of the film may be used. By doing so, when the cap itself is produced by using the laminate itself, that is, when the cap is not used as an insert or a liner, the polyurethane film surface is not outside and the appearance is good, and it is also useful for protecting the polyurethane film surface.

記以外の成形法も使用可能である。In order to manufacture the hat of the present invention, at least a part of the cloth made of the above laminated body is three-dimensionally molded. When the whole is three-dimensionally molded, not only the head covering portion but also the brim and eaves portion are simultaneously three-dimensionally molded. When a part is three-dimensionally molded, for example, only the part covering the head is three-dimensionally molded, and then the brim and the eaves are attached.
The three-dimensional molding can be performed, for example, by mounting a male and female mold on a surface plate of a hot press and pressing at a temperature of 150 to 230 ° C. for a pressing time of 15 to 60 seconds. When the laminate has a two-layer structure, it is preferable to squeeze the polyurethane film surface so that the polyurethane film surface is not scratched. Of course, molding methods other than the above can also be used.

Only a few. Further, there is an advantage that softness is imparted, light weight, low cost and high reliability are provided.
