Abstract

The invention relates to a method for measuring the thickness of anair layer under apparel. The method comprises the steps of wearingtheapparel on thermal manikin, turning on the thermal manikin to make the thermal manikin work in constant skin temperature control situation, making the thermal manikin reach a stable state; measuring temperature of each area of apparel surface, eliminating infraredtransmission power of fabric to achieve outer surface temperature of the apparel; calculating inner surface temperature of the apparel according to the outer surface temperature of the apparel; and according to the inner surface temperature of the apparel, the thickness of the air layer under the apparel is calculated by considering infrared thermal radiation between a human body and the appareland infrared transmission of apparel fabric. According to the method, the thickness of the air layer under the apparel can be measured more accurately.

Description

technical field [0001] The invention relates to the technical field of measuring the thickness of the air layer under clothing, in particular to a method for measuring the thickness of the air layer under clothing. Background technique [0002] The air layer under clothing is an important part of human clothing, and plays an important role in human body insulation and moisture permeability. The ability to quickly and accurately measure the thickness and distribution of the air layer under clothing plays an important role in the study of clothing thermal comfort. The prior art uses infrared thermography to measure the thickness of the air layer under clothing, but this method does not consider the influence of infrared radiation between the human body and clothing and the infrared transmission of clothing, and the skin surface temperature distribution of real people is also uneven. Contents of the invention [0003] The technical problem to be solved by the present inventi...
