Abstract

This article mainly studied the incidence of temperature and humidity on the moisture permeability of natural cattle leather. Firstly, it analysed the influence of a single factor of temperature or humidity on the moisture permeability of natural cattle leather based on the measured data. Then it analysed the comprehensive influence of temperature and humidity on the moisture permeability of natural cattle leather. Finally, the regression equation for the comprehensive influence of temperature and humidity on the moisture permeability of natural cattle leather was established by using the principle of least squares method through matlab software. The research shows that the higher the ambient temperature, the better the moisture permeability of natural cattle leather, when the humidity is about 67%, the moisture permeability of natural cattle leather is the highest, when the humidity is about 74%, the moisture permeability of natural cattle leather is the worst. The comprehensive influence surface of temperature and humidity on moisture permeability of natural cattle leather is.
