研究了有机硅涂层风衣面料的热湿舒适性能。由于有机硅涂层的阻隔作用，织物的隔热性和耐蒸发性均随涂层面积的增加而增加。此外，具有自相似结构的涂层织物在相同的涂层总面积下，表现出不同的隔热性能和蒸发阻力。分形理论被用来解释这一现象。当分形维数（D=1.599）接近黄金分割维数（1.618）时，热湿舒适性最佳。当涂层的分形维数小于1.599时，织物的保暖性不高。当分形维数大于1.599时，织物的蒸发阻力已经超过了人们感觉舒适的值。
In this paper, thermal and wet comforts of silicone coated windbreaker shell jacket fabrics were studied. Both thermal insulation and evaporative resistance of fabric increased with an increase in coating area due to the barrier effect of the silicone coating layer. Moreover, the coated fabrics with self-similar structures showed different thermal insulation and evaporative resistance under the same total coating area. Fractal theory was used to explain this phenomenon. Optimal thermal-wet comfort properties were obtained when the fractal dimension (D=1.599) was close to the Golden Mean (1.618). When the fractal dimension of coating was lower than 1.599, fabric warmth retention was not high enough. In contrast, fabric evaporative resistance was beyond the value at which people would feel comfortable when the fractal dimension was greater than 1.599.
