Bu çalýþmada, iki farklý (ultrasonik ve klasik) yýkama yöntemi ile yýkanmýþ %100 pamuk, %100 polyester (PES) ve %50/50 pamuk/PES karýþým dokuma kumaþlarýn kuru ve nemli haldeki termal konfor özellikleri incelenmiþtir. Yýkama sonrasý termal konfor özelliklerinin nasýl deðiþtiðinin bilinmesi üretilecek kumaþýn kullaným alanýnýn belirlenmesinde faydalý olacaktýr. Alambeta ve Permetest cihazlarý kullanýlarak kumaþlarýn termal özelliklerine, yýkama yöntemlerinin, kuru ve nemli hallerin ve lif türünün etkisi karþýlaþtýrmalý olarak analiz edilmiþtir. Elde edilen test sonuçlarý termal konfor özelliklerinin, yýkama metodu, kuru-nemli halde olma ve lif cinsine göre deðiþtiðini göstermektedir. 

In this study, 100% cotton, 100% polyester and %50/50 cotton/PES woven fabrics were washed ultrasonically and traditionally. Determination of the thermal comfort properties of raw fabrics is important, however; the changes of the thermal comfort properties of the washed fabrics have also to be known for the better garment production. Thermal comfort properties of the unwashed and the washed fabrics' were tested in both dry and wet states. The investigation of the comfort properties were performed by using Alambeta and Permetest instruments. The effect of washing methods, dry and wet states, and of fibre types on thermal comfort properties were highlighted and compared. According to the test results the washing methods, dry-wet states and the fibre types have impact on the thermal comfort properties.
