INSTRUMENT FOR MEASURING TEMPERATURE GRADIENTS IN COMPOSITE CLOTHING

Description: The instrument measures the temperature drop between the layers of clothing composites. It is designed to measure temperature gradients of conventional and intelligent clothing that has a composite structure of up to 5 layers, i.e. an outer shell, 3 layers of thermal protection and a lining.

The instrument measures the temperature drop between the layers of clothing composites. It is designed to measure temperature gradients of conventional and intelligent clothing that has a composite structure of up to 5 layers, i.e. an outer shell, 3 layers of thermal protection and a lining. The instrument has a 4-channel amplifier for K-type thermocouples with temperature compensation of the cold end of the thermocouple and analogue temperature displays and outputs for connection to AD transducers. Thermocouples are placed between the composite layers on the so-called hot plate or differential conductometer. Based on measurements of temperature gradients, the individual thermal insulation properties of each composite layer and the overall structure are determined during the design phase of the thermal properties of clothing. It can also be used to test the thermal properties of ready-made garments, where thermocouples are incorporated into the structure of the garment to measure the thermal insulation efficiency of each layer of clothing and assess the feasibility of incorporation and the cost of materials incorporated into clothing composites. Measurements can be performed under laboratory conditions on thermal mannequins and on the human body while wearing clothing.
