The transient hot-wire thermal conductivity meter for solids was used to determine the thermal conductivity of polar bear hair fibers. The experimental apparatus was tested by measuring the thermal conductivity of borosilicate glass and stainless steel from 283 to 353 K, with an absolute average deviation from the recommended values of 0.78% and 0.91%, respectively. Measurements were performed with polar bear hair fibers over the temperature range from 230 to 313 K in the transverse direction and all directions of polar bear hairs under natural and compressed conditions. The data of thermal conductivity were correlated as a function of temperature and pressure. The maximum deviation between the experiment values and the calculated values in the transverse direction and all directions of polar bear hair fibers were 0. 132 300% and 0.139 936%, and the absolute average deviation were 0. 059 312% and 0.052 844%, respectively.
