いる。2. Description of the Related Art Conventionally, there are JIS L-1096 A method and B method as a method for measuring the drying property of a cloth. In the A method, a test piece is immersed in water and sufficiently absorbed, and then it is removed from the water. There is a method of measuring the time from the time when the sample is pulled up and the water drops do not fall until it is naturally dried. In method B, the mass of the test piece before water absorption was weighed, and then it was immersed in water and allowed to absorb water sufficiently. After that, the method of measuring the mass after 10 minutes of pulling up from water to determine the amount of evaporative free water is performed.

The gist of the present invention is to provide a method for measuring the drying property of a fabric, which is characterized in that the time required for the sample to be naturally dried in a standard test room while being placed on a glass plate is measured from the change in mass. Hereinafter, the present invention will be described in detail.
【0008】本発明でいう水分平衡状態にある布帛と

3 pieces of 10 cm test piece are sampled, the test piece is placed on a glass plate of 10 × 10 cm, and the mass is measured. Then, the test piece is removed from the glass plate, and 0.2 cc of water specified in the chemical analysis method of JISK-0050 is dropped in the center of the glass plate using a micropipette. Place the test piece again on the glass plate so that the side that comes into contact with the skin comes into contact with the glass plate, absorb water,
Measure the mass. Then, with the test piece still placed on the glass plate, the time required for it to naturally dry in the test room under the standard condition is 10
Measure from the change in mass every minute.

The change in mass due to drying is calculated as the moisture content by the following formula, and is represented by the average value of three sheets. Moisture content (%) = (W T −W 0 ) / A × 100 ───── (1) W T : Weight of test piece after absorption of water T minutes W 0 : Weight of test piece before water absorption A: Drop Water mass

できる。[Production] As in the present invention, a method in which a cloth is placed on a glass plate on which water is dropped so that the surface side of the cloth contacting the skin is in contact with the glass plate to absorb water, and then the cloth is naturally dried with the cloth placed on the glass plate When the dryness is measured with, the fabric absorbs water from one side by contact and dries on the other side.
It becomes possible to measure the dryness of the cloth in a state close to the wetness of the clothes and the dryness of the sweat due to perspiration from the skin when the clothes are worn. Moreover, since the drying property can be measured with a very small amount of water droplets, the result can be obtained in a short time for the measurement.
