The aim of doctoral thesis „Development of the Thermoregulatory Clothing with the Integrated Electrically Conductive System” is to create a clothing prototype for human microclimate control with an integrated electrically conductive system, where the cooling function is performed by the Peltier element, but heat removing is based on the heat conduction processes in solid-states. The research by the development of cooling system was initiated before, but there was a need for further researches to integrate system into clothing and to verify operating efficiency of thermoregulatory system. The doctoral thesis includes the research of smart textile area: summarized terminology and concepts, explanations; analysis of the intersectional role of smart textile in the evolution of textile industry; research of electrical systems integration possibilities into textile and requirements to the smart textile. Within the thesis there are researched electrically conductive yarns application possibilities for smart textile: the yarn suitability for sewing and knitting, the creating of sewn textile based switches and knitting of resistive heating elements, as well as durability of them during washing and wearing. Generally the experiments on 11 kinds of conductive yarns that differ in structure, in used conductive material and additional processing are performed and the results are analysed and described. Developed microclimate regulatory clothing has been manufactured using two methods: adding and integration of electronica elements into pockets and sewn in tunnels of garment, as well as integrating some electrically conductive traces in the structure of fabric by sewing. So far failed to replace the Peltier elements and copper foils with the materials more suitable for the integration in the fabric structure and at the same time able to provide a necessary quality of microclimate control by the conditions of high ambient or/and body temperature. The part of electrical circuit that provides the operation of communication Panel is integrated in the structure of fabric using the electrically conductive thread. To verify the microclimate regulating garment prototype operational efficiency 11 series of experiments has been performed - a total of more than 20 experiments simulating the microclimate conditions during physical activities. The additional some garments with integrated electrically conductive systems and single elements performing certain functions where manufactured during the research of conductive yarn properties. The doctoral thesis has been written in Latvian and includes: 167 text pages, 8 chapters, 97 figures, 16 tables, 11 annexes and 146 literary sources.
