The present invention relates to a device for measuring insulation and moisture permeability of a wearable system for measuring and analyzing thermal insulation.

In recent years, a multifunctional fiber material has been developed and used. For example, a high-performance fiber having excellent air permeability from the inside to the outside while absorbing sweat from the inside of the cloth and quickly discharging it to the outside, while preventing the outside moisture from penetrating into the inside. Is being presented.

The base of this high-performance material is a fabric having moisture permeability, moisture absorption, and quick-drying function to satisfy the function of discharging the internal moisture to the outside, so as to quickly discharge the sweat from the human body and quickly dry it to help the human body temperature control. The pursuit of comfort is to maintain comfort.

Here, the moisture permeability refers to the weight (g) of water vapor passing through 1 m 2 of the fiber product under the prescribed temperature and humidity for 1 hour.

This moisture permeability can be measured when evaluating the moisture transfer from the back layer, which is in contact with the skin of the fabric, to the surface layer, which is in contact with the outside, the quick drying ability of the back layer, and the diffusion ability after the water is transferred to the surface layer.

The evaluation method for the fabric having a general moisture permeability is measured as suggested in the test method for the moisture permeability of textile products of the Korean Industrial Standards, and these conventional moisture permeation tests include the calcium chloride method, the water method, and the potassium acetate method.

Here, the wind speed of about 0.5 kPa means that the wind speed is in the range of 0.3 to 1.0 kPa when measured at a position about 10 cm away from the center of the exit from which the wind blows.

For chemical scales, a scale with a sensitivity of 1 mg or more is applied, and the moisture-permeable material does not pass water vapor, and does not corrode or change moisture permeability according to the test conditions, and the absorbent is specified in KS M 8040.

The measurement of the calcium chloride method was performed by collecting three circular test pieces of about 7 cm in diameter from the sample, and placing the surface of the test piece in which 33 g of the moisture absorbent was put into the moisture absorbent cup pretreated at about 40 ° C. to the condensation cup toward the moisture absorbent. Put the rings in order and fix them with the butterfly nut. Again, the mounting side is sealed with vinyl adhesive tape to be a test body.

The test body is placed in a constant temperature device in which air at a temperature of 40 ± 2 ° C. and a humidity of 90 ± 5% RH circulates, and after 1 hour, the test body is taken out and the weight α₁ (mg) is immediately measured.

Next, put the specimen back into the thermo-hygrostat and take out the specimen after 1 hour and immediately measure the weight α₂ (mg).

The value obtained under the above conditions is calculated by the following formula, and the water vapor permeability is calculated as the average of three tests. (The value is calculated to the first decimal place and expressed as an integer place.)

        S: moisture permeation area (cm 2)

In addition, the configuration device according to the water vapor transmission test is as follows.

First, the constant temperature and humidity device allows the air maintained at the specified temperature and humidity to circulate at a wind speed of about 0.5 kPa, and the chemical balance applies a scale having a sensitivity of 1 mg or more, and the moisture vapor cup is shown in FIG. Does not pass and does not corrode or change moisture permeability depending on the test conditions.

The measurement of this water method takes three round specimens of about 8 cm in diameter from the sample, puts 42 ml of water (distilled water or ion-exchanged water) of about 40 degrees Celsius into a permeation cup pretreated at about 40 degrees Celsius in advance, and the distance between the water and the bottom of the specimen. Is 10mm. Next, as shown in Figure 2, the back of the test piece toward the water to be concentric with respect to the moisture-permeable cup to put the packing and the ring sequentially and fixed with a butterfly nut. Again, the mounting side is sealed with vinyl adhesive tape to be a test body.

The test body is placed in a constant temperature and humidity device with air circulating at a temperature of 40 ± 2 ° C and a humidity of 50 ± 5% RH, and after 1 hour, the test body is taken out and the weight α 2 (mg) is immediately measured.

        S: moisture permeation area (cm 2)

Next, the construction apparatus according to the moisture permeation test of the acetic acid method is as follows.

First, the constant temperature and humidity device is to be controlled to the specified temperature, the chemical scale is applied to the balance with a sensitivity of 1mg or more, and the test frame support frame is made of synthetic resin cylindrical of about 80mm in diameter, about 50mm in height and about 3mm in thickness. do.

The water tank should be a structure that can enter the thermostat and fix the specimen support frame, and the moisture-permeability measurement auxiliary film has a microporous structure of about 80% of the porosity (the ratio of space to volume) and is about 25 μm thick. Phosphorus polytetrafluorourethylene film is applied.

Hygroscopic agent shall be prescribed in KS M 8318.

For measuring acetate acetate, take three specimens of approximately 20 x 20 cm from the sample. A water bath containing water at a temperature of about 23 ° C. is placed in a thermostat in which air at a temperature of 30 ± 2 ° C. circulates, and as shown in FIG. 3, the test piece is placed on the test piece support frame so that the back side of the test piece faces the outside of the support frame. Mount it with a rubber band and fix it to float in the water of the bath in the thermostat.

In the next moisture cup, the potassium acetate solution maintained at a temperature of about 23 ° C. (300g of potassium acetate was added to 100 ml of water and left for 1 day to precipitate crystals) was added to about 2/3 of the volume of the moisture cup, and the moisture permeability was measured. The auxiliary film is mounted with a rubber band to be a test body. After measuring the weight a0 (mg) with the film loading side up, immediately put the test object upside down into the specimen support frame, and after 15 minutes, remove the test body and weigh the weight α₁ (mg) with the film mounting side up.
