Description

[Detailed description of the invention] (Industrial application field) The present invention relates to waterproof garments.

(Prior art) Many waterproof and breathable fabrics are already in use on the market.For example, there is a high-density, water-repellent fabric proposed in Japanese Patent Application No. 84044/1983. or fabrics that combine water-repellent finishing with other means, such as fabrics that have been treated with water-repellent treatment and coating, fabrics that have undergone water-repellent treatment and film lamination on woven fabric, etc. can be given.

High! Fabrics that have been treated to be water repellent have good moisture permeability, but the water pressure resistance is only about 3001 to 800fi, and when strong water pressure is applied, water can penetrate into the fabric. However, it does not fulfill its waterproof function. In addition, since the water-repellent surface of such water-absorbing fabrics is always exposed to the outside, the water resistance decreases due to the adhesion of dirt during use, and water easily penetrates into the fabric, resulting in a water-repellent function. There are also 5 problems when it stops being used.

On the other hand, for fabrics that have been coated or film laminated, those with a high water pressure resistance of 500 to 2,000 nm or more are better for forming the coaching resin layer or film layer.

However, the presence of these layers generally reduces moisture permeability,
When you feel stuffy when you wear it, or when you sweat profusely, the sweat that evaporates inside the fabric can form electricity, making it uncomfortable to wear. There was also the problem of poor patient comfort.

(Object of the Invention) The present invention provides a novel waterproof garment that solves these problems.

(Structure of the Invention) The present invention provides a garment in which at least a part of the body part and sleeve part is made of an outer material and a lining material, in which both the outer material and the lining material are made of several A fabrics, and the outer material and the lining material are A waterproof garment characterized by having an air layer interposed between the two.

The garment of the present invention means a garment consisting only of a top garment, a garment consisting only of a bottom garment, a combination of a top garment and a bottom garment, or a garment formed by integrally molding a top garment and a bottom garment. It is composed of.

It is important for the garment of the present invention that both the outer material and the lining are made of water-repellent fabric.

In addition, by using the outer material and the lining, air can be created between the outer material and the lining material.
It is something that uses a ladle. In order to fix the air layer conventionally, the intermediate air layer is preferably exemplified by interposing an air-containing fabric such as woven fabric, knit fabric, or insensitive fabric between the outer fabric and the lining fabric. In particular, it is preferable to use mesh-like fabrics or lace-like fabrics with a thickness of 0.4 m or more that contain a large amount of air, rather than amorphous structures such as nonwoven fabrics; It's okay.

In addition, these outer material, lining material, and intermediate layer fabric are sewn along the normal 0-line of clothing, but the three or three are mutually 4i[f or 4i[f] by stitching. Or 43n
, or two units may be stacked one on top of the other by borrowing each other with a cylindrical agent.

The intermediate layer fabric can be either water repellent or non-water repellent.

As the water-repellent fabric used in the present invention, any known water-repellent fabric may be used, but the water pressure resistance of the outer material is preferably 300 squares or more, more preferably 500 f1 or more.

In addition, regarding the breathability of the outer material and lining, it is preferable that the air in the intermediate layer has low permeability so that air easily escapes under pressure and is not replaced by water, less than 2 ex3/cd/see, more preferably 1 ex '/ aj It must be less than or equal to 7 formulas.

Regarding the relationship between the water pressure resistance of the outer fabric and the lining, a more favorable result can be obtained if the water pressure resistance of the lining is equal to or at least greater than that of the outer fabric.

Regarding air permeability, it is preferable that the air permeability of the scarred area is equal to or smaller than that of the outer material.

FIGS. 1 and 2 are cross-sectional views horizontally showing an example of a cross-section in the thickness direction of the body portion of the garment according to the present invention.

The body part consists of a outer material 1 and a lining material 2 made of water-repellent material, and an air layer 4 is interposed between the outer material 1 and the lining material 2. Furthermore, as shown in FIG. 2, a menswear 3 as an intermediate fabric is interposed between the outer fabric 1 and the lining 2 to stably form an air layer 4.

In addition, in the garment of the present invention, it is not necessary to use such a structure over the entire garment, but only in parts where waterproof performance is particularly required, such as the first part of the body and the back of the lower garment. However, the remaining portion can be formed from a normal water-repellent fabric.

, Effects of the Invention) Since the garment of the present invention has the above-described structure, it has excellent waterproofness, moisture permeability, and distortion.

Surprisingly, its water pressure resistance, which is a substitute for waterproof performance, is 1.5 to 2 times higher than that of the 1-piece fabric (4 items) used for the outer material or lining, and its performance can be maintained semi-permanently. It is something that can be maintained. Moreover, the inside of the outer material and lining is 1.
If the air layer is fixed by a fabric interposed in the itl, this effect can be stably obtained, and the intermediate layer fabric may be made of coarse fabric (for example, , mesh-like fabric, lace-like fabric), this effect is remarkable.

This is thought to be because even if water leaks from the outer layer, the air layer in the middle prevents the leak from reaching the lining.

In addition, since the garment of the present invention uses water-repellent fabrics for both the outer and lining, the surface on the side of the air layer (1', 2' in Figure 1) that exists between them is susceptible to friction due to use of the garment. The waterproof performance can be maintained semi-permanently with almost no decrease in waterproof performance due to wear and dirt.

(Example 1) Ultrafine polyethylene terephthalate multifilament with a diving shrinkage rate of 8 inches (total denier 64 denier,
Filament R144 Wood) A yarn made of a blend of polyethylene terephthalate multifilament (total denier 50 denier, number of filaments 24) with a diving shrinkage rate of 17% is used for the wheel, and the total cover factor of Keikyo is 2070. We wove a flat paste material with a diameter density of 18
4 lines/3.79cm, grass height 104 lines/3.79m). The fabric is refined, relaxed, dried, and
After precenting and dyeing and drying, a water repellent finish was applied using a regular linear resin with the following formulation.

Composition of Rokusui Treatment Solution After applying the water-breaking agent treatment solution to the fabric by a padding method, it is dried at a temperature of 100°C, and then dried at a temperature of 180°C for 30 minutes.
After heat treatment for 0 seconds, calender treatment was performed using a heating steel roll at 170'cO on the long side and a paper rule on the surface to obtain a water-repellent fabric.

The fabric thus obtained has a water pressure resistance of 430n1, an air permeability of 0.8 cc/d/Sec, and a Q water resistance of 10
0 points, transparency rA, gender 6000 g/d/24 h
It was r.

Waterproof clothing was created using this water-repellent fabric as the main parts of the upper garment, such as the body and sleeves, the outer material of the body of the lower garment, and the outer material of the finished garment.

The initial water pressure resistance of this waterproof garment was 630 m, and after repeated wearing and washing 10 times, the water pressure resistance was 600 n, maintaining the initial performance.

Also, when examining the other performance of this garment in the body area, breathability is 0.4 cc/cat/type, and moisture permeability is 5600g/+z.
It was found to be a waterproof and breathable garment that was comfortable to wear and had a water rupture time of 1/24 hours.

(Example 2) The same water-repellent fabric as used in Example f141 was used for the outer material and lining, and the medium ii! shown below was used. A jacket was created using l and fi fabrics for the body and sleeves.

As an intervening fabric, a raschel diameter flat fabric using 3 reeds using polyester filament yarn of 500 denier and 96 filaments for each reed of the bank and middle part (diameter density 9 threads/inch thread density 21 courses/inch) , i
A formation method L1: 20,02L' 66.44.6
6.00.22.00 L; 00.2# 22.00.44.22.44) was dyed and finished using a conventional method, and was made into a mesh-like fabric with a thickness of approximately 0.8 mm. , two waterproof garments, A1 using this mesh-cho fabric, and Oboro 2 using mesh-cho fabric treated with water sprinkling using the same recipe as in Example 1. We created it and investigated its performance.

The results are shown in Table 1.

Both AI and 42 have excellent waterproof performance, but Haya 1's garment has high water pressure resistance even though the middle layer fabric has not been treated to break water.

(Example 3) A weakly twisted polyester filament yarn (300T/M) of 75 denier and 72 filament was used as the warp yarn, and an ultra-fine type polyester filament yarn (64 f nille 144 filament) was inserted into the S yarn at high density without twisting. After dyeing the high-grade plain fabric using a conventional method, water-repellent finishing and calendering were performed using the method described in Example 1.
A water-repellent high-density taffeta with a warp thread count of 164 and a wheel thread count of lθ3 per 4 tx was obtained. The breathability of this tack is 0.5
cc 101/set, moisture permeability 65001/+/
/24hr.

The water pressure resistance was 900 m, and the water repellency was 100 points.

A waterproof garment was prepared in the same manner as in Example 1, except that the fabric described in Example IK was used as the outer fabric and the fabric obtained by the above method was used as the lining. The initial water pressure resistance of this waterproof garment reached 1200 mm, and almost no decrease was observed even after washing it 10 times.

Water repellency: 100-90 points initially, 90 points after 10 washes
There was almost no decline in the score.

Furthermore, its breathability was 0.3 cc/cd/sec, and its moisture permeability was 5000 g/vl/24 br, indicating that it was a waterproof garment that was comfortable to wear.

In addition, the measurement method of each physical property shown in Examples 1 to 3 is water resistance: A
