This paper presents a study conducted on the thermo-mechanical properties of knitted structures, the methods of manufacture, effect of contact pressure at the structural binding points, on the degree of heating. The test results also present the level of heating produced as a function of the separation between the supply terminals. The study further investigates the rate of heating and cooling of the knitted structures. The work also presents the decay of heating properties of the yarn due to overheating. Thermal images were taken to study the heat distribution over the surface of the knitted fabric. A tensile tester having constant rate of extension was used to stretch the fabric. The behavior of temperature profile of stretched fabric was observed. A comparison of heat generation by plain, rib and interlock structures was studied. It was observed from the series of experiments that there is a minimum threshold force of contact at binding points of a knitted structure is required to pass the electricity. Once this force is achieved, stretching the fabric does not affect the amount of heat produced.
本文介绍了一项关于针织结构热机械性能、制造方法、结构结合点处接触压力对加热程度影响的研究。测试结果还给出了作为供电终端之间间距函数的发热水平。该研究进一步考察了针织结构的加热和冷却速率。这项工作还展示了纱线因过热导致的发热性能衰减。拍摄了热图像以研究针织面料表面的热分布。使用具有恒定延伸速率的拉伸试验机对织物进行拉伸。观察了拉伸织物的温度分布行为。研究了平针、罗纹和双罗纹结构的发热比较。从一系列实验中观察到，针织结构的结合点处需要有一个最小接触阈值力才能通电。一旦达到这个力，拉伸织物不会影响产生的热量。
