Abstract

PURPOSE:To evaluate the function of cloth almost at the time of putting on it by providing a body dummy with the cloth and moving and twisting the arms and legs of the body dummy repeatedly. CONSTITUTION:Humidity sensors 2 are fitted to the breast, upper abdomen, back, etc., of the body dummy 1. Further, driving parts 4A and 4B are provided to twist the dummy 1 supposing that the dummy is in walking motion, thereby letting the dummy bend and stretching repeatedly. Further, water scattering devices 3 are installed right above, above in front of, and by the dummy 1. The dummy 1 is provided with a long-sleeved shirt and water is scattered while the dummy is put in motion, thereby taking a test in the artificial rain. At this time, the amount of water from the seams and zipper is measured from the wet of the cotton shirt. Similarly, the dummy 1 is put in motion and cloths having wind resistance, dust resistance, etc., are tested. Thus, tests are taken while the dummy 1 is in repetitive motion, so the cloths can be evaluated in the state very close to the actual wear state.

Description

DETAILED DESCRIPTION OF THE INVENTION 1. Detailed Description of the Invention [Field of Industrial Application] The present invention is an apparatus for evaluating functions of clothing, such as waterproofing, windproofing, and dustproofing.

[Conventional technology and its problems]

Currently, JIS is used as a method for evaluating the functions of fabrics.
Various methods are shown in . For example, typical methods for evaluating the waterproofness of fabrics include the JIS L 1096° water pressure test method and the water repellency test method. Further, there are methods such as JIS L1096 and air permeability test method to evaluate the windproof property of a fabric, and JIS20208 method and the like to evaluate moisture permeability. Furthermore, JIS Z89 is used to evaluate the dust resistance of fabrics.
01 method is used, and the JIS method is widely used for other functional evaluations. However, although these methods can evaluate the functions of a fabric such as waterproofing, windproofing, dustproofing, weatherproofing, etc., the functionality of clothes sewn from the fabric cannot be determined at all. That is, clothing has seams, zippers, pockets, ventilation areas, etc., and sometimes incorporates other fabrics. Therefore, even if the fabric alone has sufficient desired functions, it is difficult to say that it has the desired functions as clothing. For example, in waterproof clothing, even if the fabric is sufficiently waterproof, rain can still penetrate through the seams and part of the zipper.

For this reason, it is sometimes possible to prepare a piece of fabric with a seam or a zipper, measure the waterproofness, windproofness, etc. of this part, and predict the function of the garment when it is made into a garment. Although this is possible, the functionality of the clothing changes due to the various movements of the person wearing the clothing.

As mentioned above, despite the importance placed on the function of clothes as well as the function of fabrics, there is currently no device that can evaluate the function of clothes.

[Means for solving problems]

The present invention provides a clothing function evaluation device in which a sensor for evaluating the clothing function is installed on a human dummy that has the function of making repeated movements.

The present invention will be specifically explained below.

The human body dummy in the present invention is a dummy that imitates the shape of a human body, and any dummy can be used, such as not only the whole body but also only the upper body, only the lower body, no arms, no head, etc. In addition, the size of the dummy can be selected for children or adults, and the gender can be selected for men or women. Furthermore, it is also possible to create a dummy with only a skeleton by making the inside of the dummy hollow.

This dummy has the ability to repeat arbitrary movements necessary for evaluating clothing functions, such as arm and leg movements assuming walking, twisting movements, forward bending movements, bending and stretching movements, etc. depending on the purpose. It may be manufactured using known methods and devices to perform the same motion. For example, in evaluating waterproofness,
In particular, it is best to give the dummy a twisting motion, and for dustproof evaluation, it is best to make it perform bending and stretching motions. Known techniques can be used to drive these movements. For example, the drive unit may be composed of a motor, gears, cams, cranks, etc., and these may be built into the dummy, or may be connected to the dummy from the outside via a connecting rod to give motion to the dummy. One or more required number of sensors that can evaluate the function to be measured are installed on or inside the dummy.

For example, to evaluate waterproofness, use a humidity sensor, moisture content needle, or water-absorbent clothing, to evaluate windproofness, use an anemometer, and to evaluate dustproofness, use a chisel-tiful counter, and other sensors. For example, sensors such as a solar transmittance meter, a thermometer, and an electromagnetic wave receiving antenna can also be used.

Moreover, all known sensors can be used as the above-mentioned sensors.

These terminals are glued to the surface of the dummy or placed between the dummy and clothing. The position of the sensor (terminal) is not particularly limited; for example, in the evaluation of waterproof clothing, it may be installed at points near parts of zippers, seams, etc. that are likely to leak water.

Further, it is preferable to install the sensor not only on the surface or inside of the dummy, but also on the outside of the clothes worn on the dummy, and to measure the difference from the inside of the clothes.

A human dummy that has the ability to repeat desired movements is placed in any environment to evaluate the functionality of clothing. for example,
It is installed in an environmental test chamber where the environment can be changed freely or in a natural environment. The environmental test chamber has variable temperature and humidity, and is preferably equipped with a water sprinkler to evaluate waterproofness, a fan to generate wind, a dust generator to evaluate dustproofness, a light source, and the like.

〔Example〕

Example 1 A clothing waterproof testing device as shown in FIG. 1 was manufactured.

1 was a male-sized upper body dummy, and 2 was a humidity sensor (Cordix CHMT-CHM), which was installed at 8 locations on the left and right chest, upper abdomen, back, and rear of the upper abdomen. Further, 4A and 4B are drive units that give the dummy repeated movements of right twisting motion and pressure twisting motion, assuming that the dummy is walking.

This device was designed to have a twist angle of 10~b. Furthermore, a water sprinkler device 3 was installed at a distance of 1.0 m from the dummy at the top, upper front, and sides of the dummy.

The dummy of this device was dressed with a long-sleeved cotton shirt and then with long-sleeved waterproof clothing.The dummy's twisting angle was 30' and the number of movements was 90 times/min.
The waterproofness of the clothes was measured for 205+ under the following conditions: 00Oφ water receptacle was made and the water storage capacity was measured.

The results of the waterproof evaluation are shown in Table 1. By twisting the dummy, we were able to obtain measurement results that were very close to the actual wear test in the rain, making it clear that it could fully replace the wear test. . However, when the dummy did not twist, the water leakage area, the amount of water leakage, and the humidity inside the clothes were all lower than when the clothes were actually worn, and it was found that the waterproofness of the clothes could not be accurately determined.

(Extra color above) Table 1 Example 2 A device similar to Example 1 was used, but instead of the water sprinkler 3, two fans with a diameter of 3o (7) were installed in two stacks at a location 3 m away from the dummy side. In addition, the dummy is a dummy with only a skeleton with a hollow inside, and the wind speed a↑゛ (Rion Co., Ltd. pA
M-03) was installed.

The dummy of this device was dressed in a windproof garment with a front zipper, maple fabric, and horizontally elongated ventilation sections measuring 1.0 cm in length on the left and right chests. In addition, a fan was rotated, and a wind of 5 m/sea was blowing on the side of the dummy, and the dummy was twisted 70 times at a twisting angle of 40 degrees.
The windproof properties of clothing were evaluated in terms of times per minute.

The results are shown in Table 2, and each time the dummy twists,
It was found that wind entered the clothes through the ventilation section. From this result, the position of the pentillation part,
We were able to determine the size, which is an important evaluation for manufacturing windproof clothing that does not get stuffy.

Table 2 Example 3 A whole-body dummy was manufactured that repeated a 70' forward bending movement from the waist every 5 seconds, and a take-take counter (Kc-otA manufactured by Rion Co., Ltd.) was placed on the surface of the dummy. Terminals were placed on the chest and back.

This device was placed in a class 100 clean room, and dust-proof clothing was placed inside. Next, the circulation fan in the clean room was stopped, and a smoke cylinder was used to generate dust such that the amount of dust with a particle size of 1 μ or more in the clean room was 50,000 pieces/lcf. In this state, the dummy was bent forward for 10 minutes, and the amount of dust that had entered the inside of the dummy was measured.

As shown in Table 3, it was found that clothes with poor dustproof properties allow a large amount of dust to enter into the clothes due to forward bending movements, which was useful in the development of dustproof clothes.

Table 3 Average value of chest and back [Effects of the invention] The device for evaluating the functionality of clothing according to the present invention can evaluate the functionality of clothing, and by repeatedly exercising the dummy, it is possible to evaluate the functionality of clothing when it is actually worn by a human being. When you do this, you can evaluate the functions of clothing that are very close to each other.

Moreover, it is of course possible to evaluate the function of not only clothes but also cloth by covering the cloth as a dummy.
