Ki~inin viicudu ile gevre arasmdaki fizyolojik, psikolojik ve fiziksel uyum sonucu ortaya 91kan memnuniyet duygusu olarak tammlanabilen termal konforu etkileyen en 6nemli parametreler, giysi sisteminin deriyle temasl sonucu ortaya 91kan sogukluk ve IslaklIk hisleridir. Bu hisler ise giysi sistemi-gevre havasl arasll1da, giysinin katmanlan arasmda ve kuma~ igerisinde meydana gelen lSI ve hitle transferi mekanizmalanna bagII olarak ortaya 9lkar. Kuma~ ve giysilerin termal konfor performanslannm incelenmesi i9in yapIlan 9alI~malarda, vOcutta meydana gelen fizyolojik degi~imlerin yanll1da bu degi~imlere yol a9an lSI ve kOtle transferi mekanizmalannm da incelenmesi gerekmektedir. Bu 9ah~manm amaCI, bu konuda uzun yIllardlr yapIlan teorik ve pratik 9ah~malardan bir klSm1l11 inceleyerek 9ah~malann hangi dogrultuda ilerledigini tespit etmektir. 

Thelmal comfort, which can be defined as 'a pleasant state of physiological, psychological and physical hanl10ny between human body and its environment' is mainly controlled by the sensations of coldness and dampness arising from skin contact with the garment system. These sensations are originated from heat and mass transfer mechanisms occming between garment system-environment, between clothing layers and within fabric structure. In order to investigate the thelmal comfort performances of fabrics and galment systems, besides physiological changes in human body, heat and mass transfer mechanisms ensuring these changes should also be analyzed. The aim of this paper is to examine some ofthe theoretical and experimental studies about heat and mass transfer mechanisms occuring in fabric and garment systems and detemline the direction of these studies.
