Therefore, when designing and producing clothing, the evaluation of clothing comfort represented by perspiration performance, thermal resistance and moisture resistance becomes an indispensable step. When testing perspiration performance, thermal resistance and moisture resistance, on the one hand, it is necessary to simulate the body temperature of various parts of the human body on the dummy model, and on the other hand, it is necessary to simulate the environment in which the dummy is located, such as ambient temperature and ambient humidity.

[0034] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following is a detailed description in conjunction with the accompanying drawings and preferred embodiments.

[0035] The invention provides a device and a system for testing the comfort level of clothing. The device for testing the comfort level of clothing can better detect the comfort level of clothing.

[0036] Figure 1 FIG. 1 is a system block diagram of a device for testing clothing comfort provided by a first embodiment of the present invention. Figure 2 Shown Figure 1 A schematic diagram of the cross-sectional structure of the middle dummy model 40, Figure 3 Shown Figure 1 A schematic diagram of the structure of the temperature control components inside the dummy model 40. Figures 1 to 3 As shown, the device for clothing comfort testing provided by the first embodiment of the present invention includes a controller 10, a dummy temperature control unit 20, a dummy temperature detection unit 30 and a dummy model 40. The dummy temperature control unit 20 and the dummy temperature detection unit 30 are electrically connected to the controller 10. The dummy model 40 includes a lining 41. A constant temperature area 411 is formed in the lining 41. The constant temperature area 411 is filled with a fluid medium, such as a gas medium or a liquid medium. The dummy temperature detection unit 30 detects the temperature of the fluid medium and transmits the temperature information to the controller 10. The controller 10 controls the temperature of the constant temperature area 411 through the dummy temperature control unit 20.

[0037] The controller 10 may be a circuit module including a single chip microcomputer or other processors, etc., for acquiring and analyzing data collected by peripheral devices. The lining 41 is usually made of a material with good thermal stability, such as metal, plastic, rubber, and supports the dummy.

[0038] In this embodiment, by filling the constant temperature area 411 with a fluid medium and controlling the temperature of the fluid medium through the dummy temperature detection unit 30 and the dummy temperature control unit 20, the outer surface of the lining 41 can simulate the epidermis of the human body. When evaluating the comfort of clothing, since the temperature of the outer surface of the lining remains relatively stable, after the dummy model 40 is put on the clothing to be tested, the heat dissipation of the dummy model 40 after the clothing to be tested is calculated, and according to the area of ​​the clothing to be tested, the thermal resistance of the clothing can be obtained more accurately to evaluate the thermal insulation performance of the clothing.

[0039] Preferably, the fluid medium may be a liquid medium to better maintain the temperature stability in the liner 41 .

[0040] Furthermore, the dummy model 40 also includes an artificial skin 42 which is sleeved on the inner lining 41 , and a gap 43 is formed between the artificial skin 42 and the inner lining 41 , and simulated sweat is stored in the gap 43 .

[0041] Since the artificial skin 42 is arranged outside the lining 41, and a gap 43 filled with simulated sweat is formed between the artificial skin 42 and the lining 41, the artificial skin 42 can simulate sweating. Generally, the simulated sweat evaporates naturally. During exercise, the temperature of the constant temperature area rises, and the simulated sweat is heated and evaporated. After the garment to be tested is put on the dummy model 40, the moisture resistance and thermal resistance of the garment to be tested and its boundary layer (the air between the garment and the dummy) can be calculated to evaluate the comfort of the garment.

[0042] During the evaluation, since the moisture resistance and thermal resistance of the artificial skin 42 are known at a constant temperature, the moisture resistance and thermal resistance of the test garment when it is put on the dummy model 40 are measured, and then the moisture resistance and thermal resistance of the artificial skin 42 are respectively subtracted to obtain the moisture resistance (Formula 1) and thermal resistance (Formula 2) of the test garment and its boundary layer, so as to quantify the comfort of the garment. The calculation formulas of the moisture resistance and thermal resistance are as follows:

[0043]

[0044]

[0045] In the formula, R e is the moisture resistance of the clothing and its boundary layer air (Pa·m 2 / W);

[0046] R d is the thermal resistance of the clothing and its boundary layer air (℃·m 2 / W);

[0047] A is the body surface area (m 2 );

[0048] t s It is the temperature of the artificial skin (℃). Temperature sensors are set on the surface of the skin at each temperature to measure the temperature value of the skin surface in real time.

[0049] t a is the ambient temperature (°C);

[0050] p isf is the temperature t s Saturated vapor pressure on the inner side of the lower artificial skin (Pa);

[0051] p af is the temperature t a Saturated vapor pressure of the environment (Pa);

[0052] RH a is the relative humidity of the environment (%);

[0053] E is the heat of vaporization of water (W·h / g);

[0054] G e is the evaporative sweat output of the dummy (g / h);

[0055] H is the total heat dissipation of the dummy (W). Usually, the total heat dissipation can be calculated based on the heating power of the heating device;

[0056] R es is the moisture resistance of the artificial skin (Pa·m 2 / W),

[0057] R ds is the thermal resistance of the artificial skin (℃·m 2 / W).

[0058] The artificial skin is a fixed material, and the thermal resistance and moisture resistance of the material itself are known.

[0059] The mannequin design ensures that except for the exposed part (the part in direct contact with the clothing interface) with a certain thermal conductivity, the fluid pipeline for transmitting the fluid adopts a weak thermal conductivity material to avoid heat loss. The calculation of the heat dissipation power of each part of the mannequin is mainly calculated by the heating power and the heat loss of the unit volume of the fluid medium. Specifically, for a mannequin with a single constant temperature area 411, the heat dissipation power is equal to the heating power of the constant temperature source; for a mannequin with multiple constant temperature areas 411 and multiple constant temperature areas 411 have independent constant temperature sources to provide constant temperature fluid medium, the heat dissipation power of each temperature zone is equal to the heating power of each constant temperature fluid medium; for a mannequin with multiple constant temperature areas 411 and only one constant temperature source to provide constant temperature fluid medium for multiple constant temperature areas 411, an input end temperature sensor (not shown) is provided at the constant temperature source heat output end, and a return end temperature sensor (not shown) is provided at the constant temperature source return end, and the heating power is estimated by the temperature change and the medium storage volume of the constant temperature zone.

[0060] In the dummy model 40, each joint of the dummy model 40 is rotatably arranged on the dummy model 40. Specifically, the device for clothing comfort test also includes a motion unit 70, which is electrically connected to the controller 10 and is arranged on each joint of the dummy model 40. The controller 10 drives the limbs of the dummy model 40 to move through the motion unit 70. At the same time, the temperature of the constant temperature area 411 is adjusted to the temperature of the human body during exercise by the controller 10, and the evaporation amount of the simulated sweat can also be adjusted by the controller 10. The evaporation amount of the simulated sweat can also be increased by increasing the temperature of the constant temperature area 411, thereby forming a structure in which the airflow exchange between the clothing and the human body in the state of movement will change. The device for clothing comfort test can evaluate the warmth and moisture permeability of clothing when the human body is in motion.

[0061] See also Figure 2 and Figure 3 In this embodiment, the dummy model 40 includes a plurality of independent constant temperature areas 411, and each of the constant temperature areas can be independently temperature controlled. For example, there are eight independent constant temperature areas, such as the head constant temperature area, the torso constant temperature area, the left arm constant temperature area, the right arm constant temperature area, the left leg constant temperature area, the right leg constant temperature area, the left foot constant temperature area, and the right foot constant temperature area. A dummy temperature control unit 20 and a dummy temperature detection unit 30 are provided in each constant temperature area 411. The temperature of the fluid medium in each constant temperature area 411 can be different, so as to simulate different body temperatures in different areas, and to facilitate the comfort evaluation of various clothing, such as long-sleeved clothes, short-sleeved clothes, pants, hats, socks or shoes. A connecting valve 412 is also provided between two adjacent constant temperature areas 411 to control the circulation of the fluid medium in the two constant temperature areas.

[0062] More specifically, in this embodiment, the dummy temperature control unit 20 includes a heating rod 21 and a homogenizer 22, such as a stirrer or a stirring pump. The heating rod 21 and the homogenizer 22 are arranged in the constant temperature area 411, the heating rod 21 heats the fluid medium, and the homogenizer 22 stirs the fluid medium to make the temperature in the fluid medium more uniform.

[0063] Please continue to refer to Figure 2 In the present embodiment, an electrical circuit arrangement conduit 44 is further provided inside the dummy model 40. The electrical circuit arrangement conduit 44 enters the dummy model 40 from the head of the dummy model 40 and extends into each constant temperature area 411, so that the temperature control components (heating rod 21 and uniformizer 22) of the dummy temperature control unit 20 and the dummy temperature detection unit 30 are electrically connected to the controller 10.

[0064] Furthermore, a fluid pipeline 23 is provided on each constant temperature area 411 , and the constant temperature area 411 is connected to the outside through the fluid pipeline 23 . The fluid pipeline 23 can transport and discharge the fluid medium to the constant temperature area 411 connected thereto to control the content of the fluid medium in each constant temperature area 411 .

[0065] Figure 4 Shown Figure 2 Schematic diagram of the structure of each membrane layer of artificial skin, such as Figure 2 and Figure 4 As shown, in this embodiment, the artificial skin 42 includes an inner protective layer 421, a micro-nano layer 422 and an outer protective layer 423 in order from the direction close to the inner lining 41 to the direction away from the inner lining 41. The inner protective layer 421 is formed with a mesh water-retaining structure on the side facing the gap 43, which on the one hand offsets the influence of the liquid level pressure difference in the simulated sweat, and on the other hand can ensure that the simulated sweat has a certain fluidity. The micro-nano layer 422 is formed of a membrane material with a microporous structure, the maximum pore size of which is much larger than the diameter of the water vapor molecule, and the minimum pore size is much smaller than the diameter of the liquid water molecule, thereby ensuring the natural evaporation of the gaseous water molecules and blocking the liquid water from flowing out of the artificial skin. The outer protective layer 423 is formed of a wear-resistant material to protect the micro-nano layer 422. When the dummy model 40 is provided with a fluid pipeline 23, the fluid pipeline 23 passes through the artificial skin 42 and then extends into the constant temperature area 411.

[0066] In this embodiment, under the influence of the constant temperature areas 411 in the lining layer 41, the simulated sweat in the gap 43 can vaporize and then pass through the artificial skin 42 to reach the garment to be tested, so as to facilitate the testing of the moisture resistance and thermal resistance of the garment to be tested and its boundary layer.

[0067] On the head of the dummy model, a simulated sweat containing chamber 424 connected to the gap is provided. The simulated sweat containing chamber 424 is connected to the outside through a connecting tube 425 to replenish the simulated sweat. A flow meter (not shown) is also provided on the connecting tube 425 to measure the amount of replenished simulated sweat and obtain the evaporation amount of the simulated sweat.

The constant temperature source 24 is arranged to ensure the constant temperature of the fluid medium, and the fluid medium is circulated through the fluid medium circulation pipeline to ensure the uniformity of the temperature of the fluid medium in each constant temperature area 411.

[0069] In this embodiment, a constant temperature source 24 is disposed in the fluid medium circulation pipeline corresponding to each constant temperature area 411 to adjust the temperature of the fluid medium in the multiple constant temperature areas 411 respectively.

[0070] Furthermore, in this embodiment, in the left arm constant temperature area, the right arm constant temperature area, the left leg constant temperature area, and the right leg constant temperature area, the heat inlet pipe 26 is located at one end of each constant temperature area 411 close to the trunk constant temperature area, and the heat outlet pipe 27 is provided at one end of each constant temperature area 411 away from the trunk constant temperature area, so as to more realistically simulate the constant temperature of the dummy model 40 at the armpit, groin, and other positions.

Figure 7As shown, the third embodiment of the present invention is basically the same as the second embodiment, except that, in this embodiment, the fluid medium is a liquid, and the dummy temperature control unit 20 includes a high-temperature fluid constant temperature tank 241, a low-temperature fluid constant temperature tank 242, a fluid medium mixing device 28, a fluid pump 25, a heat inlet pipe 26, and a heat outlet pipe 27. The high-temperature fluid constant temperature tank 241 and the low-temperature fluid constant temperature tank 242 are both connected to the fluid medium mixing device 28, and the fluid medium mixing device 28 is connected to a plurality of heat inlet pipes 26, and is respectively connected to each constant temperature area 411 through a heat inlet pipe 26. The fluid medium mixing device 28 is electrically connected to the controller 10, and the controller 10 distributes the flow of the high-temperature medium and the low-temperature medium through the fluid medium mixing device 28, mixes the distributed high-temperature medium and the low-temperature medium to obtain liquid medium of different temperatures, and sends the liquid medium into a specific constant temperature area 411. That is, the fluid medium mixing device 28 can control the flow of the high-temperature medium and the low-temperature medium entering each heat inlet pipe 26. For a plurality of independent constant temperature areas, the temperature sensor 21 is disposed in each independent constant temperature area to monitor the temperature of the constant temperature area.

[0072] In a specific embodiment, the fluid medium mixing device 28 includes multiple mixing modules, temperature detection modules, and flow control valves.

The skin micro-change module 80 causes the artificial skin 42 of the dummy model to produce microscopic movement, so as to more accurately calculate the thermal resistance and moisture resistance of the clothing in the moving state.

When evaluating the comfort of clothing, since the artificial skin 42 is arranged outside the lining 41, and a gap 43 filled with simulated sweat is formed between the artificial skin 42 and the lining 41. Therefore, the artificial skin 42 can perform sweating simulation, and then after the clothing to be tested is put on the dummy model 40, the moisture resistance and thermal resistance of the clothing to be tested and its boundary layer can be calculated to evaluate the comfort of the clothing. By setting up the device for clothing comfort testing, a stable evaluation environment can be provided for the simulation dummy as much as possible, and relevant parameters of the environment can be controlled and changed relatively quickly.
