Abstract

In this paper, the influence of compressibility on the thermal contact conductivity of diamond-shaped quilted lining for special purpose clothing will be determined with the aim of obtaining the accurate data essential for the technical design of special purpose clothing, the required thermal properties. The tests were carried out on the basis of the newly established measurement method using a multipurpose differential conductometer, developed, patented, calibrated and installed in the Laboratory for thermal insulation properties of clothing at the Department of clothing technology. The materials mentioned are used for the production of thermal inserts and linings for special purpose clothing and have excellent thermal properties. Two specimens were oversewn using the sewing technique with square chamber segments, while the third specimen was joined using the ultrasonic welding technique with the so-called mirror-image trajectory of the ultrasonic welding, but in practice they are also called diamond-shaped quilted lining. The geometric parameters of the seam/weld and chamber segments, which also influence the thermal properties of the materials used, are determined with regard to the sewing or welding technique.
