Fibrousmaterial is a complex porous medium and steady test methodsare the main test approaches we currently depend on tostudy the heat transfer properties. The application of unsteady testmethods on fibrous material is still not mature. In thispaper, some systematic studies are taken to investigate this problem.By analyzing the main factors impacting the test results, itis found that the local heat convection potentially excited byimposing test temperature can be avoided by limiting the internaltemperature gradient and the so-called dual-phase lagging effects are negligibleso that the feasibility of the unsteady test method isverified via both theoretical analysis and experimental data.
