项目摘要

The influence of moisture, water and heat transfer between the skin and fabrics on tactile sensations were studied by several simulation and subjective tests. The following results were obtained.1) The heat transfer from the heat source plate to the environment through a fabric was measured using Thermolabo II (KESF-7) for newly developed lingerie fabrics and sports wear fabrics. The effect of moisture regain on the heat loss was investigated. The increase of moisture regain increased the heat loss and was influenced by the water and vapor transport properties of fabrics. For wet two layered fabrics having pile structure on one side, when the pile surface was placed on the heat plate, the total heat loss from the fabric was smaller than when the other side (knitted structure) was placed on the heat source.2) The sensation of "wetness" and "coolness" was investigated for two lingerie fabrics by subjective measurements. Two different water temperature such as 50℃ and 20℃ were chosen. Wetness was detected by subjects more clearly at 50℃ compared with that of 2O℃. Both moisture regain and temperature of a fabric are related to these sensations.3) Measurements of the friction between pile, knit fabrics and artificial skin were carried out for various moisture regains of fabrics. When the surface of the fabrics were totally wet, the frictional coefficient was smaller than that of the dry state of fabrics. For light weight knit fabrics, the degree of adhesion to the artificial skin depends on the moisture regain of fabrics and was reflected in the amount of frictional force.

通过模拟实验和主观实验，研究了皮肤与织物之间的水分、水分和热量传递对触觉的影响。1）使用Thermolabo II（KESF-7）对新开发的内衣织物和运动服织物测量从热源板通过织物到环境的热传递。研究了回潮率对热损失的影响。回潮率的增加增加了热损失，并受织物的水和蒸汽传输性能的影响。对于单面具有绒头结构的两层湿织物，绒头表面置于加热板上时，织物的总热损失小于另一面（针织结构）置于热源上时的热损失。2）通过主观测试研究了两种内衣织物的“湿”感和“凉”感。实验选用50℃和20℃两种不同的水温。在50℃时，受试者对湿度的感觉比20 ℃时更清晰。织物的回潮率和温度都与这些感觉有关。3）对各种织物的回潮率进行了绒头织物、针织物和人造皮肤之间摩擦力的测量。当织物表面完全湿润时，摩擦系数小于织物干燥时的摩擦系数。对于轻质针织物，与人造皮肤的粘附程度取决于织物的回潮率，并反映在摩擦力的大小上。
