Problems solved by technology

But this method only focuses on simulation, and there is always a certain gap with the real situation, and the physical structure of different textiles is always different, which virtually increases the difficulty of simulation

Abstract

The invention discloses a method and a device for testing the dynamic heat transfer characteristics of textiles. The test device includes a test component, a transmission mechanism, a lifting mechanism, a pillar and a base. The test components include upper platen, lower platen, heating plate, copper support plate, pressure sensor and heat flow sensor. The transmission mechanism is composed of upper baffle plate, motor, coupling, bearing, worm gear mounting frame, worm and worm gear. The test method is to realize the up and down movement of the upper platen through the motor, transmission mechanism and lifting mechanism, and the stop position of the upper platen is controlled by the pressure sensor. During the dynamic contact process between the upper platen and the textile, due to the temperature difference between the upper platen and the lower platen , the heat flow sensor set above the lower platen can measure the dynamic changes of heat flow and heat transfer through the textile during the contact process. Through testing and calculation, two characteristic indexes of thermal regulation time and thermal stimulation intensity are obtained, which can be applied to the textile testing industry to realize the rapid measurement of the dynamic heat transfer characteristics of textiles.

Description

technical field [0001] The invention belongs to the field of testing the physical characteristics of textiles, in particular to the field of testing the dynamic heat transfer characteristics of textiles. Background technique [0002] Thermal conductivity (or heat transfer) is one of the fundamental properties of various materials. When there is a temperature difference between different parts of the object or two objects with different temperatures are in direct contact, there will be a certain amount of heat transfer. The heat transfer performance of textiles is one of the important properties of clothing products. It is an important basis for measuring the thermal insulation and thermal regulation performance of textiles, and it is also one of the decisive factors for consumers to measure the quality of fabrics. Therefore, it is particularly important to study the heat transfer performance of textiles in the research and development of textiles. [0003] Most of the test...
