The housing 102 is configured to provide an accommodating space 104, and the accommodating space 104 may be a cuboid. The pedestal 106, the electronic balance 108, the heating device 110, the moisture permeable cup 116, and the wind situation simulation device 140 are all placed in the accommodating space 104. The box 102 can provide a steady-state environmental source during measurement, that is, the thickness and structure of the box 102 can prevent the fabric moisture permeability measuring system 100 from being interfered by the external environment during operation, and the material of the box 102 can be metal. Plastic or wood.

The base 106 is a mobile platform that is movable relative to the housing 102 to facilitate removal of the base 106 and components thereon from the housing 102. For example, the base 106 carries an electronic balance 108, a heating device 110, a moisture permeable cup 116, a rainstorm situation simulation device 130, and a wind situation simulation device 140.

More specifically, the electronic balance 108 is placed on the base 106, the heating device 110 is placed on the electronic balance 108, and the moisture permeable cup 116 is placed on the heating device 110. The rainstorm scenario simulation device 130 and the windstorm scenario simulation device 140 are respectively fixed to the rear side and the top of the base 106. The position of the wind situation simulation device 140 corresponds to the moisture permeable cup 116 such that the wind energy provided by the wind situation simulation device 140 is blown through the moisture permeable cup 116. The rainstorm scenario simulator 130 is positioned substantially directly above the moisture permeable cup 116.

The rainstorm scenario simulation device 130 is used to simulate a natural environment The rainy day situation when faced with outdoor activities. The rainstorm scenario simulation device 130 includes a water supply device 132, a compressed air source 134, and an adjustable showerhead 136. The water supply device 132 and the compressed air source 134 may be disposed outside the casing 102, and the adjustable spray head 136 is disposed in the accommodating space 104 to spray the water mist to the moisture permeable cup 116. More specifically, the opposite ends of the adjustable spray head 136 in the accommodating space 104 have passages, and the two passages are respectively connected to the water supply device 132 and the compressed air source 134 by pipelines.

The water supply device 132 can be a water storage device such as a water tank or a water storage tank to provide a rainwater source of rain. A high pressure air gas is stored in the compressed air source 134. When the rainstorm scenario simulation device 130 is activated to simulate a rain shower scenario, the water inside the water supply device 132 and the high pressure air supplied from the compressed air source 134 are respectively flowed through the pipeline to the adjustable nozzle 136 for mixing, and then ejected from the adjustable nozzle 136. . At this time, the water is dissipated by the high-pressure air and turned into a mist and sprayed to the accommodating space 104.

In the rainstorm scenario simulation device 130, an adjustable spray head 136 is used to further simulate the rain conditions of different rainfall sizes. The adjustable nozzle 136 can have a control knob to adjust the aperture of the nozzle on the adjustable nozzle 136. The larger the aperture, the larger the water volume of the water mist. By adjusting the spray state of the adjustable nozzle 136, the output water can be controlled to change the rainfall. size. The adjustable spray head 136 is placed over the moisture permeable cup 116, and the distance between the adjustable spray head 136 and the cup opening of the moisture permeable cup 116 is about 0-80 cm.

The rainstorm situation simulation device 130 sprays the water mist on the accommodating space 104, which can change the rain spray range and the rainfall amount by adjusting the adjustable spray head 136, and the rainfall simulation range provided by the rainstorm situation simulation device 130 is 0~100ml/min.

The wind situation simulation device 140 is used to simulate the wind situation faced when performing outdoor activities in a natural environment. The wind scenario simulator 140 has a parallel fan 141 to provide a source of wind to the moisture permeable cup 116. The parallel fan 141 includes a motor 142, a rotating shaft 146, and a plurality of blades 148, wherein the blades 148 are disposed on the rotating shaft 146 in parallel with each other. The motor 142 has a rotor 144, the rotating shaft 146 is connected to the rotor 144, and the rotational speed of the motor 142 is controllable, and the wind power provided by the parallel fan 141 can be adjusted by adjusting the rotational speed of the motor 142. The wind situation simulation device 140 The range of wind power provided is approximately 0 to 8 meters per second.

It should be noted that although only one moisture permeable cup 116 is shown in the figure, in the actual measurement, a plurality of moisture permeable cups 116 are often placed at the same time to take an average value as a measurement result, so the wind situation simulation device 140 outputs The wind, as shown in FIG. 2, is preferably a parallel wind parallel to the first direction 149 to create a stable flow field in the accommodating space 104 to blow through the plurality of moisture permeable cups 116.

The power control box 150 includes a power switch 152, a control panel 154, and a display screen 156. The power control box 150 is connected to the electronic balance 108, the heating device 110, and the wind situation simulation device 140, respectively, to provide a source of power and to adjust environmental conditions. After the power switch 152 is activated, the display screen 156 immediately displays the surface temperature of the heating device 110 and the wind speed in the environment inside the cabinet 102. The user can control the heating temperature provided by the heating device 110 and the wind environment provided by the wind situation simulation device 140 by operating the control panel 154.

The fabric moisture permeability measurement system 100 further includes an analysis unit 160 that includes an analysis display software for calculating the moisture permeability of the fabric to be tested. The analysis unit 160 is connected to the electronic balance 108 and the moisture permeable cup 116, respectively.

Referring to Fig. 3, it is a top view of the heating device in Fig. 1. The heating device 110 includes a plurality of coils 112 and a plate body 113. And a region 114 is defined on the plate 113 to place the moisture permeable cup 116. The heating method of the heating device 110 generates heat by energizing the coil 112 and transmits heat to the moisture permeable cup 116 through the plate body 113, and heat transfer through the plate body 113 causes the moisture permeable cup 116 to be uniformly heated when heated.

The heating device 110 has a heating range of 25 degrees Celsius to 50 degrees Celsius. When the surface temperature of the human skin is simulated, the temperature of the heating device 110 can be controlled at 35 °C.

Please refer to FIG. 4A and FIG. 4B at the same time, which is a top view and a side view of the moisture permeable cup in FIG. 1 . The moisture permeable cup 116 includes a cup body 122 and a fixing member 124. After the fabric 120 is placed flat on the cup opening of the cup 122, the fabric 120 is secured to the cup 122 by the fixing member 124. The fixing member 124 may include a hollow fixing ring 123 and a fixing screw 121. The fabric 120 is placed between the fixing ring 123 and the cup 122, and the rear fixing screw 121 locks the fixing ring 123 to the cup 122 to fix the fabric 120. . It should be noted that the cup body 122 has a coverless design, and the fixing ring 123 is also hollow, so that the fabric 120 in the moisture permeable cup 116 is in an open environment, that is, the air and moisture inside the moisture permeable cup 116. The fabric 120 can be exchanged with the external environment of the moisture permeable cup 116.

The moisture permeable cup 116 further includes a sensor 118, which is a sense of temperature and humidity. The sensor 118 is disposed on the cup 122. Since the temperature and humidity in the moisture permeable cup 116 may change with time, the sensor 118 can instantly detect and collect the temperature and humidity in the moisture permeable cup 116 and then return it to the analysis unit 160.

The method for measuring the moisture permeability is to add a certain amount of water to the cup body 122, and then place the fabric 120 on the cup mouth and fix it with the fixing member 124. As described above, the moisture permeable cup 116 is an open environment, and the cup is open. After the water in the body 122 evaporates into moisture, it will diffuse into the accommodating space 104 through the fabric 120 due to the difference in humidity. Therefore, the overall weight of the moisture permeable cup 116 may vary with time, and the moisture permeability is obtained by dividing the weight change of the moisture permeable cup 116 per unit time by the area of the object to be tested. In the fabric moisture permeability measuring system 100 of the present invention, the moisture permeability can be measured by the electronic balance 108, and the weight of the moisture permeable cup 116 can be transmitted back to the analyzing unit 160 for calculation.

Next, please refer to FIG. 5A and FIG. 5B simultaneously, which respectively show a schematic diagram of the moisture permeable cup lying flat and obliquely placed on the heating device in the fabric moisture permeability measuring system of the present invention. During the measurement, the moisture permeable cup 116 can be placed on the heating device 110 in a flat or oblique manner in accordance with environmental requirements. The mode adopted when it is laid flat is the general case. That is to say, when it is necessary to measure a special situation, for example, to simulate a rainy situation, a mode of using a diagonal shift can be adopted, the purpose of which is to prevent experimental inaccuracies due to water accumulation caused by rain.

Compared with the prior art, the fabric moisture permeability measuring system 100 of the present invention can simulate the different environmental conditions simulated, in addition to simulating the surface temperature of the human body, the rainy situation and the wind situation, and the temperature and Humidity is also listed as an important parameter, rather than simply calculating the moisture permeability of the fabric 120 to present a more realistic condition of the fabric 120 when worn by the human body outdoors.

When the measurement begins, the electronic balance 108 remains open, and the heating device 110, the rainstorm scenario simulator 130, and the wind scenario simulator 140 set the desired environmental conditions. Next, the fabric 120 is placed in the cup 122 mouth and secured. When the measurement is performed, the weight of the moisture permeable cup 116 and the temperature and humidity collection in the cup are transmitted to the analysis unit 160 by the electronic balance 108 and the sensor 118 to obtain the moisture permeability and related information.

In summary, the fabric moisture permeability measuring system provided by the present invention aims to make the measurement of the moisture permeability performance of the fabric more in line with the actual outdoor wearing condition. The following will be explained in conjunction with the actual test data.

In order to compare the moisture permeability measurement system of the fabric with the conventional measurement method, in addition to using the system to simulate different situations, the basic measurement of an unused heating device, a rainstorm situation simulation device, and a wind situation simulation device is also measured. Wet behavior. In the experimental data provided below, each fabric material was measured three times under each environmental condition, and the measurement results were averaged. The fabric materials were respectively polytetrafluoroethylene (PTFE) and hydrophilic film (Hydrophilic membrane). ) and Micro-porous membrane.

Table 1 Measurement results of basic moisture permeability

Table 1 shows the measured values of the basic moisture permeability of the three fabric materials, including moisture permeability, temperature and humidity. It did not match any simulation scenarios during the measurement. The initial environmental conditions 126 in the moisture permeable cup are both temperature 23.5 ± 1 ° C and humidity 50 ± 2% RH, and in the case of ventilation, the fixed wind speed does not exceed 0.3 m / sec (can be regarded as a windless state).

Please refer to FIG. 6 , which is a comparative diagram of the moisture permeability of different fabrics when simulating human skin temperature according to an embodiment of the fabric moisture permeability measuring system of the present invention. The measuring method is to place the moisture permeable cup on the heating device. As shown in Fig. 6, after the human skin temperature is simulated by using the fabric moisture permeability measuring system of the present invention, the moisture permeability of the fabric is higher than the temperature of the unsimulated human skin, and the higher the simulated temperature, the measured fabric permeability. Humidity performance also increases.

Table 2 shows the measured values of simulated human skin temperature (30 ° C) for the three fabric materials in Figure 6, including moisture permeability, temperature and humidity. It can be seen from the results of Table 2 that the moisture permeability of the three fabric materials is significantly greater than that of the basic moisture permeability (see Table 1), and the average moisture increase is about 70%.

Table 3 shows the measured values of simulated human skin temperature (35 ° C) for the three fabric materials in Figure 6, including moisture permeability, temperature and humidity. It can be seen from the results in Table 3 that after the simulated temperature rise, the moisture permeability of the fabric continues to rise, and the average is about 2.5 times the moisture permeability of the basic moisture permeability (see Table 1), and the temperature inside the cup continues to rise.

Table 4 shows the measured values of simulated human skin temperature (40 ° C) for the three fabric materials in Figure 6, including moisture permeability, temperature and humidity. It can be seen from the results in Table 4 that after the simulated temperature rise, the moisture permeability of the fabric is greater than the previous result, which is about 4 times the moisture permeability of the basic moisture permeability (see Table 1) and the temperature inside the cup is also higher.

Combining the above results of simulating different human skin temperatures, the fabric does exhibit different results due to ambient temperature. It can be seen that the body temperature of the human body affects the performance of the moisture permeability of the fabric.

Next, please refer to FIG. 7 , which is a comparative diagram of the moisture permeability of different fabrics in the simulated rain shower situation (the moisture permeable cup is laid flat) in an embodiment of the fabric moisture permeability measuring system of the present invention. The initial environmental conditions in the moisture permeable cup are the same, and the measurement method is to place the moisture permeable cup on the heating device. As shown in Fig. 7, after simulating the rainy environment using the fabric moisture permeability measuring system of the present invention, when the external environment of the moisture permeable cup increases with the rainfall, the internal moisture permeability is reduced, especially in the middle and large. In the state of rainfall, there is no moisture permeability at all.

Table 5 shows the measured values of the simulated rain conditions of 20 ± 5 ml / min (small rain) in the three fabric materials in Figure 7, including moisture permeability, temperature and humidity. It can be seen from the results of Table 5 that the moisture permeability of the three fabric materials is significantly reduced compared with the basic moisture permeability, and the humidity in the moisture permeable cup is slightly increased.

Cup flat)

Table 6 shows the measured values of the simulated rain conditions of 50±5ml/min (medium rainfall) for the three fabric materials in Figure 7 (the moisture-permeable cup is laid flat), including moisture permeability, temperature and humidity. It can be known from the results of Table 6 that the three fabric materials have zero moisture permeability, and the humidity in the moisture permeable cup is still greater than the basic moisture permeability.

Table 7 shows the measured values of the simulated rain conditions of 100±5ml/min (heavy rain) for the three fabric materials in Figure 7, including moisture permeability, temperature and humidity. It can be seen from the results of Table 7 that the moisture permeability of the three fabric materials is still zero compared with the basic moisture permeability, and the humidity in the moisture permeable cup is greater than the previous results.

Comprehensively simulating the results of different rain conditions, the fabric does show different results due to different rain conditions. When the outdoor rainfall is greater, the moisture permeability of the fabric is reduced, and even there is no moisture permeability.

Next, please refer to FIG. 8 , which is a comparative diagram of the moisture permeability of different fabrics (the moisture permeable cup obliquely) when the simulated rain shower situation is applied to an embodiment of the fabric moisture permeability measuring system of the present invention. The initial environmental conditions in the moisture permeable cup are the same, measured In the manner, the moisture permeable cup is placed obliquely on the heating device to prevent the rainy environment simulation device from causing water on the fabric to block moisture, which affects the accuracy of the experiment. As shown in Figure 8, as in the previous rainy situation, when the external environment of the moisture permeable cup increases with the rainfall, the internal moisture permeability is still reduced, and the medium and heavy rainfall conditions are still completely opaque. Wet behavior.

Table 8 shows the measured values of the simulated rain conditions of 20 ± 5 ml/min (small rain) for the three fabric materials in Figure 8, including moisture permeability, temperature and humidity. It can be seen from the results of Table 8 that the moisture permeability of the three fabric materials is still significantly reduced compared with the basic moisture permeability, and the average is about 50% of the original, while the humidity in the moisture permeable cup is slightly increased.

Table 9 shows the measured values of the simulated rain conditions of 50±5ml/min (medium rain) for the three fabric materials in Figure 8, including the moisture permeability, temperature and humidity. It can be known from the results of Table 9 that the three fabric materials have zero moisture permeability, and the humidity in the moisture permeable cup is still greater than the basic moisture permeability.

Table 10 shows the measured values of the simulated rain conditions of 100±5ml/min (large rainfall) for the three fabric materials in Figure 8, including the moisture permeability, temperature and humidity. It can be seen from the results of Table 10 that the moisture permeability of the three fabric materials is still zero compared with the basic moisture permeability behavior, and the humidity in the moisture permeable cup is greater than the previous several results. The results of simulating different rain conditions and sloping cups are similar to those of the moisture permeable cups. In the case of small rainfall, the cups are placed at a higher humidity than the normal cups (average approx. Increase by 15%).

Please refer to FIG. 9 again, which is a comparative diagram of the moisture permeability of different fabrics when simulating a wind situation in an embodiment of the fabric moisture permeability measuring system of the present invention. The initial environmental conditions in the moisture permeable cup are the same, and the measurement method is to place the moisture permeable cup on the heating device. As shown in Fig. 9, after simulating the wind situation using the fabric moisture permeability measuring system of the present invention, the external environment of the moisture permeable cup follows the wind The speed is enhanced and the internal moisture permeability is also increased.

Table 11 shows the measured values of the simulated wind conditions of 2.0 ± 0.05 m / s (the amount of breeze) for the three fabric materials in Figure 9, including moisture permeability, temperature and humidity. It can be seen from the results of Table 11 that the moisture permeability of the three fabric materials is increased, and the moisture permeability is increased by about 13% compared with the basic moisture permeability behavior (see Table 1).

Table 12 shows the measured values of the simulated wind conditions of 4.0±0.05 m/s (stroke volume) for the three fabric materials in Figure 9, including moisture permeability, temperature and humidity. It can be seen from the results of Table 12 that the moisture permeability of the three fabric materials continued to increase, and the moisture permeability increased by about 20% compared with the basic moisture permeability behavior (see Table 1).

Table 13 shows the measured values of the simulated wind conditions of 6.0 ± 0.05 m / s (strong air volume) for the three fabric materials in Figure 9, including moisture permeability, temperature and humidity. It can be seen from the results of Table 13 that the moisture permeability of the three fabric materials is greater than the previous wind situation, and the moisture permeability is increased by about 31% compared to the basic moisture permeability behavior (see Table 1). However, it can be seen that if polytetrafluoroethylene (PTFE) is used as the material to be tested, the humidity in the moisture permeable cup will also decrease significantly with the wind speed.

In summary, in the windy situation, the difference in wind speed does affect the actual moisture permeability during wear, and the moisture permeability of the fabric is also significantly enhanced with the increase of external wind power.

In summary, the object of the present invention is to obtain the moisture permeability performance of the actual wearing fabric when it is outdoors. From the experimental results, it is known that the fabric is indeed subjected to the human body for the basic moisture permeability and the comparison with the moisture permeability under different simulation scenarios. Skin temperature, rain conditions and wind conditions have three environmental effects, and obviously show different moisture permeability. Therefore, the fabric moisture permeability measuring system of the present invention simulates different environmental changes, so that the test result is more in line with the result that the human body actually wears the fabric for outdoor activities.
