Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to waterproof clothing.

[0002]

2. Description of the Related Art A large number of waterproof and moisture-permeable fabrics have already been used in the market.
No. 2111649, a fabric obtained by subjecting a high-density woven fabric to a water-repellent treatment, or a fabric obtained by combining other means in addition to the water-repellent treatment, that is, a fabric obtained by subjecting a woven or knitted fabric to a water-repellent treatment and coating. And a fabric obtained by subjecting a woven or knitted product to water repellent treatment and film lamination.

A water-repellent cloth made of a high-density woven fabric has good moisture permeability, but only has a water pressure resistance of about 300 mm to 800 mm. When a strong water pressure is applied, water permeates into the cloth. And does not play the role of its waterproof function. In addition, in such a water-repellent fabric, the water-repellent surface is constantly exposed to the outside, so that the water repellency is reduced due to adhesion of dirt or the like at the time of wearing, so that water easily penetrates into the inside of the fabric and does not have a waterproof function. It also has problems.

On the other hand, in the case of a fabric coated or coated with a film, the water pressure resistance is 500 mm to 2000 mm.
The above high value can be obtained by forming the coating resin layer and the film layer. However, in the presence of these layers, in general, the moisture permeability is reduced, and when worn, a feeling of stuffiness or, when sweating in large amounts, sweat evaporating to the inside of the fabric is dewed and the comfort is deteriorated. There was also a problem that the feeling of wearing as clothes was poor due to coating, film, and lamination.

[0005]

SUMMARY OF THE INVENTION The present invention provides a novel waterproof garment which solves these problems.

[0006]

SUMMARY OF THE INVENTION The present invention is directed to a garment in which at least a part of a body part and a sleeve part are composed of a surface material and a lining, wherein the lining is woven with high-density filament yarn at a high density. A mesh cloth made of a water-repellent fabric having a thickness of 300 mm or more and having a permeability of 10 cc / cm ² / sec or more for the outer material, and having a thickness of 0.4 mm or more between the outer material and the lining. Waterproof fabric having a structure in which an air layer formed of a fabric or a lace-like fabric having a high air content is interposed, and a surface material and a lining are separated by the high air content fabric. It is.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The garment of the present invention is formed of only an upper garment, only a lower garment, a combination of an upper garment and a lower garment, and further integrally formed with the upper garment and the lower garment. It means something and is composed of a dress material and a lining material.

The outer material of the garment of the present invention preferably has a relatively dense structure for the purpose of relieving water pressure from the outside, while a loose structure is preferable for keeping the inside of the garment comfortable.

When a structure that satisfies both conditions is expressed by air permeability, it is 10 cc / cm ² / sec or more and 50 cc / cm ² / s.
ec or less is preferable. Also, since the outer material is for lowering the water pressure, it is not always necessary to be water-repellent, but when used in the rain, it is preferably water-repellent to reduce surface swelling. .

[0010] Further, the garment has an air layer interposed therebetween by using a surface material and a lining material. The intermediate air layer is a fabric, to positively fix the air layer,
A preferred example is one in which a fabric having a high air content, such as a knit or a nonwoven fabric, is interposed between the outer material and the lining. In particular, the thickness is 0.4 mm more than an amorphous structure such as a nonwoven fabric.
It is preferable to use a material having a high air content, such as the above-mentioned mesh-like fabric or lace-like fabric, but these may be used in combination.

The outer material, the lining material, and the intermediate layer fabric may be sewn along a normal sewing line of the garment, or may be sewn to each other by eight stitches. ,
The three members or the two members are used by being overlapped with each other by bonding with an adhesive or the like.

The intermediate fabric may be either water-repellent or non-water-repellent, and is preferably water-repellent in order to prevent water from entering.

As the water-repellent woven fabric for the lining used in the present invention, known woven fabrics can be used. In particular, as shown in the examples, high-density woven fabrics woven with ultrafine filament yarns having a single denier of 1.1 denier or less. Is preferably exemplified, and the waterproof pressure of the lining is preferably 300 mm or more, and more preferably 500 mm or more.

Regarding the air permeability of the outer material, a relatively high density of 50 cc / cm 2 is used for the purpose of reducing external water pressure.
preferably cm ² / sec or less of the fabric, whereas more than 10cc / cm ² / sec is preferable from the comfort.

FIG. 1 is a cross-sectional view showing an example of a cross section in the thickness direction of the best viewing portion of the garment of the present invention in a horizontal direction.

The best-looking portion is composed of a surface cloth 1 and a lining 2 made of a water-repellent fabric, and an air layer 4 is provided between the surface 1 and the lining 2.
Is interposed. The air layer 4, as shown in FIG.
An air layer 4 is stably formed by interposing a mesh 3 as an intermediate fabric between the outer material 1 and the lining 2.

In the garment according to the present invention, it is not necessary to use such a structure over the entire garment, and in particular, it is required to provide a waterproof part, for example, a part of the body, such as a shoulder or a back body of the lower garment. It is possible to use, and to form the rest with a normal water-repellent fabric.

[0018]

The garment of the present invention has excellent waterproof and moisture-permeable properties because it has the above structure. Surprisingly, the water pressure resistance, which is a substitute property of the waterproof performance, is 1.5 times the water pressure of the cloth (woven fabric) used for the outer material or the lining.
性能 2 times or more, and its performance can be maintained semipermanently. In addition, when the air layer is fixed by the fabric interposed between the outer material and the lining, this effect is stably obtained, and particularly, the intermediate layer fabric has a small contact area with the outer material and the lining. This effect is remarkable in the case of a cloth (for example, a mesh-like cloth residual cloth or a lace-like cloth). It is considered that this is because the leakage from the surface material does not reach the lining due to the middle air layer.

Further, since the garment of the present invention uses a water-repellent woven fabric for the lining, the surface (2 'in FIG. 1) on the side of the air layer existing therebetween is waterproof by friction during use of the garment. The waterproof performance can be maintained semi-permanently with almost no reduction in performance, deterioration of waterproof performance due to wearing dirt, and the like.
