灰色评判环境因素对皮革透湿性的影响程度

Evaluation of the effect of environment factors on the moisture permeability of leather using grey system theory

灰色综合评判在穿着过程中环境温度、相对湿度等环境因素对皮革透湿性的影响程度,定量地分析了各因素对透湿量的影响程度。分析结果显示:环境温度对透湿性的影响最大,其次是压强、相对湿度、透湿时间。由于环境中的各因素之间是相互影响的复杂关系,通过灰色理论应用,使它们的综合影响结果具有一定可信度,且为研究服装舒适性,开发更好的适应环境的皮革服装提供依据。

The quantity of moisture transmitted through leather under different environment conditions was measured with self-made instrument, and the effect of ambient temperature, relative humidity and so on of the leather garment during wearing on its moisture permeability was evaluated using grey system theory. Quantitative analysis of each facor on the moisture permeability was conducted, and it revealed that they were in such an order： ambient temperature 〉 pressure 〉 relative humidity 〉 time of moisture transmittance. Since the： environment factors are influencing on each other and rather complicated, the results evaluated by means of grey system theory have certain degree of confidence, thus providing a scientific basis for researchers to design comfortable leather clothing for adapting the change of environment.
