摘　　要：利用动物毛皮热物性测试平台对水貂短毛黑色型、白色型、蓝宝石色型、银蓝色型等4个品种的水貂皮的总传热系数进行了测定,并测定了各色型水貂皮毛长度和毛密度,为制定水貂皮质量量化评价标准提供参考。结果表明:同一风速作用下,不同色型水貂传热系数差异性不显著(P>0.05)。随着风速的增加,水貂皮的传热系数显著提高(P<0.01),被毛的隔热性能下降,绒毛长度和毛密度是影响水貂皮总传热系数的主要因素。雄性水貂皮较雌性传热系数低,雄性水貂皮具有更高的隔热性能,被毛特征的性二型是导致雌雄水貂皮隔热性能差异的主要原因。通过总传热系数测定,能准确的反映不同水貂皮被毛特征产生的隔热性能的差异。The fur of farmed mink （mustela vision） is the main raw material for fur garment, so the heat retention property of fur are usually key parameters for evaluating fur heat insulation. To deminish the inadequacies of qualitative description of thermal insultation properties of the fur due to lack of quantative index, the paper measured the morphological indexes included the hair density and length of guard hairs and under hairs and the overall thermal transfer coefficients of furs from 4 breeds, namely black shorthair type, white, sapphire and silver blue minkswith fur thermal physical test platform. The results showed that thermal transfer coefficients did not reveal significant differences among various types of minks; the increase of wind speed brought forward higher thermal transfer coefficients of mink fur and lower heat insulting properties, under hairs length and hair density were the main factors that influenced the heat transfer property. Concerning the gender differences, the overall heat transfer coefficient of male mink fur was lower than that of the female and thermal heat insulting properties of the former higher than the latter, mainly caused by the dimorphism of fur morphological characteristic. The test of the overall thermal transfer coefficients exactly displayed the thermal insultation differences of mink furs to prepare references for quantative assessment index of mink fur quality.
