Problems solved by technology

However, this fake head adopts the active sweating method, and its sweating water supply is a quantitative water supply mode. It is often impossible to estimate in advance how much sweating is needed during the test, so the thermal comfort index of the hat cannot be determined: Effective measurement of thermal and moisture resistance

Abstract

The invention relates to a method for measuring heat resistance and moisture resistance of a hat. The method comprises the following steps of: removing the influence of an air layer outside a dummy head by using strong surround wind; measuring the moisture resistance of simulative skin; measuring the moisture resistance of the air layer outside the dummy head under a windless condition; and finally, realizing synchronous measurement on the heat resistance and the moisture resistance of the hat under a normal condition. According to the method for measuring the heat resistance and the moisture resistance of the hat, heating power and sweat rate of the dummy head can be accurately measured, and moreover, the one-step synchronous measurement can be realized on the heat resistance and the moisture resistance of the hat on the sweaty dummy head.

Description

technical field [0001] The invention relates to a method for measuring clothing heat resistance and moisture resistance, in particular to a method for measuring hat heat resistance and moisture resistance. Background technique [0002] At present, many kinds of sweating thermal dummies have appeared in the world. However, due to various reasons, there have been no papers on the evaluation of the thermal comfort of hats using thermal dummies. In fact, using the entire thermal dummies Evaluating hats alone presents many technical problems in specific measurements. It is more realistic and reasonable to use the dummy head to measure the thermal comfort of the hat than the whole dummy. There have been multiple simulation heads in the world, but the fake head capable of simulating sweating is only developed by Herring, A.M, etc. to evaluate the physiological comfort of motorcycle safety helmets (Hering, A.M.Weder, M.Rickards, N.Mattle, M. Evaluation of physiological properties ...
