Evaluating the Degree of Influence of Clothing Factors on the Moisture Permeability of Sheepskin through Grey Theory

摘要

The moisture permeability of sheepskin is affected by both the thickness of the leather and environmental factors. Using grey theory and 'five data modelling', the information that affects the moisture permeability of sheepskin is generated and developed, so as to extract valuable information. In this paper, the amount of water vapour transmission of sheepskin materials of different thicknesses under different environmental factors is tested experimentally, and the water vapour transmission of sheepskin is related to the four parameters that affect its moisture permeability, and the relative correlation analysis, absolute correlation analysis, and comprehensive correlation are further performed. The analysis results show that the biggest factor that affects the water vapour transmission of sheepskin is the internal and external pressure of sheepskin, the second factor is the humidity of sheepskin, the third factor is the thickness and the smallest factor is the temperature of the sheepskin.
