Performance charasteristics of sleeping bags and design of the sleeping bag that providing high wearing performance

Sleeping bag; is a multi-layer textile product essentially including exterior fabric (shell), filling and lining which consisting of three parts and that generally people used it who staying outdoors at night, without losing body temperature and in order to get an efficient sleep. Especially, sleeping bags which are used in extreme sports and military fields have vital importance. The aim of this thesis is determination of mechanical properties of sleeping bags that are provided from market. According to the analysis of comparative results, it is aimed to design the sleeping bag that may provide the best utilization features with different outer fabric, the inner core and lining materials. Furthermore, making a comparative analysis and improvement for widely used sleeping bags on the market in terms of examining fastness and handle properties of the outer fabrics was aimed. While water vapor resistance is generally high of sleeping bags used in the study that has a high thermal resistance value as well. Therefore, according to the test results, when the thermally high comfort sleeping bag, in terms of water vapor resistance is less comfort. As a result, the thermal performance of sleeping bags features not only is determined to use also depends on the person's physiological properties.
