Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a skin type hot plate apparatus capable of simultaneously measuring the climate and moisture resistance of clothing,

The present invention relates to a skin type hot plate device capable of simultaneously measuring the climate and moisture resistance of clothing, and more particularly, to a skin type hot plate device capable of measuring the temperature and humidity inside the air layer under a clothing environment in which an air layer is formed between the skin and clothing The present invention relates to a skin type hot plate device capable of simultaneously measuring the climate and moisture resistance of a garment so as to measure airflow and temperature and humidity in an external environment so that a more substantial and accurate moisture permeability and insulation performance can be measured and evaluated.

In the general garment condition, an air layer is formed between the skin and the garment (fabric). However, in the conventional cloth moisture permeability and warming test, only the moisture resistance is measured under the clothing environment in which the cloth is adhered to the skin, The moisture permeability and the thermal insulation performance evaluation under the actual wearing environment of the fabric have not been accurately performed.

The moisture permeability and warmth performance evaluation test of this fabric is made through a test method that can simulate the relationship between the fiber product and the skin, and the moisture resistance (Ret), that is, how well moisture from the human body is discharged through the fiber, Or not discharged. In addition, the temperature and humidity measurement value between the human body and the moisturizing fiber is calculated in an environment in which perspiration continues. The temperature of the normal sweating condition is set at 35 DEG C as body temperature, and is set to an external environmental condition at a relative humidity of 40% and an air velocity of 1 m / s.

On the other hand, when the moisture permeability resistance is large, the moisture permeability is low while the moisture permeability is low, and when the moisture permeability resistance is low, the moisture retentivity is low while the moisture permeability is high. If there is no air layer in the clothes, the test is carried out by stacking and fixing the fabric on the moisture-proof vinyl which passes water vapor and does not pass the liquid on the heat plate which is supplied with water for vaporizing the skin for simulating skin. Is expressed and measured as the amount of water vapor that passes, that is, the power consumed when the liquid vaporizes.

The moisture resistance value, that is, the value showing the resistance of the skin to the outside of the clothes, shows that the higher the moisture content is, the more moisture is contained between the skin and the clothes. The lower the moisture content, the better moisture permeability and comfort can be judged.

However, in the past, performance and evaluation based on only the moisture-permeation resistance value under a clinging environment in which the fabric is not adhered to the skin, the actual moisture permeability and the thermal insulation performance under the clinging environment in which the air layer is formed, And there is a problem that the objectivity and accuracy of the moisture permeability and insulation performance evaluation of the fabric are lacked.
