Testing device for temperature rise of far-infrared textiles and testing method

Abstract

The invention discloses a testing device for the temperature rise of far-infrared textiles and a testing method. The testing method is characterized in that a thermal manikin for simulating the use temperature of the real wearing of a human body is introduced, the surface of the thermal manikin has the current more-mature related technical product for simulating a sweating skin layer, the change of the temperature is detected by utilizing an intelligent multipoint average thermometer under the radiation of a far-infrared radiation source, not only is the influence of the external radiation energy considered, but also the influence of the self radiation energy of a human body is also considered; and simultaneously, due to introduction of the thermal manikin, the influence of the individual differences and the psychological factors in a human-body experimental method is eliminated. The testing device and the testing method disclosed by the invention have the advantages that the design is scientific and standard, the credibility of the testing result is high and the temperature-rise performance of the far-infrared textiles can be reasonably reflected.

Description

technical field [0001] The invention belongs to the technical field of textile testing, and in particular relates to a far-infrared textile temperature rise testing device and a testing method. Background technique [0002] Far-infrared textiles have attracted much attention as a product integrating heat storage, heat preservation, health care and antibacterial functions. Since the 1980s, researchers from all over the world have begun to study them. Far-infrared textiles are effectively fused with far-infrared ceramics and textiles, which can absorb electromagnetic waves emitted by the environment or the human body in a wide range of wavelengths, and radiate far-infrared rays with a wavelength of 2.5-30 μm. Functional textiles that regulate blood circulation, regulate metabolism, reduce the degree of association of water molecules and improve cell activity. But to achieve the above purpose, the following conditions must be met: one is to absorb external energy, and the othe...

Problems solved by technology

However, the emissivity detection method cannot completely exclude the influence of objective factors such as textile surface structure, color, and sample moisture regain. Therefore, to a certain extent, the performance of far-infrared textiles cannot be fully explained simply based on the emissivity of textiles.

In addition, the emissivity test methods all have the problem of referring to the selection of black bodies. There is no real black body in reality, so the approximate degree of black bodies selected in different test instruments is different, resulting in differences in emissivity test results.
