Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a clothing comfort simulation device for measuring the comfort of clothing under various conditions when the clothing is worn.

0002

2. Description of the Related Art Conventionally, when developing materials for clothing or designing clothing, it has been necessary to examine in advance the comfort level of the clothing when worn.

[0003] For this reason, in the past, a method was generally used to evaluate the comfort of clothing by computer analysis of the thermal properties of clothing using a thermal mannequin and the physiological values measured during wearing the clothing through wearing experiments. Most of these are merely analyzes and evaluations of clothing materials or single characteristics of clothing, mainly between the human body and clothing, and are based on the analysis and evaluation of clothing materials under various conditions in which clothing is actually worn. It was not possible to fully evaluate comfort.

[0004] In other words, the comfort level when wearing clothing is closely related to the temperature, humidity, etc. of the microscopic space formed between the skin and the clothing, and the temperature, humidity, etc. inside the clothing. This is because the condition of clothing must be determined under various conditions that combine the external environment, clothing, and human body for each use of clothing.

[0005] Therefore, in the past, Japanese Patent Application Laid-Open No. 58-8
As shown in Japanese Patent Publication No. 8659 and Japanese Patent Application Laid-Open No. 60-3550, various external environmental conditions are artificially created, as well as temperature and humidity conditions due to sweat etc. on the human body side. A new technology has been developed that uses sensors to measure the temperature and humidity inside clothing, and measures the comfort of clothing worn by people under various conditions.

[0006] However, even when the comfort of clothing is measured based on what is shown in these publications, it does not necessarily match the comfort when people actually wear the clothing. For clothing with low breathability, such as cold-weather clothing and dust-proof clothing in IC factories, the measured comfort of the clothing and the comfort when the clothing is actually worn by a person are different. There were considerable differences, and it was not possible to accurately determine in advance how comfortable these garments would be when actually worn.

[0007]

[Problems to be Solved by the Invention] This invention provides a method for measuring the comfort of clothing under various external environmental conditions when developing materials for clothing or designing clothing. The objective is to be able to evaluate the comfort of clothing under the same conditions as when a person actually wears the clothing and engages in activities.

[0008] Here, the present inventor has discovered the cause of the difference between the comfort of clothing as measured by those disclosed in the above publications and the comfort of clothing felt when a person actually wears the clothing. We examined the following.

[0009] As a result, the inventor of the present invention realized that the effects of carbon dioxide emitted from the human body were not taken into consideration in the above-mentioned publications.

[0010] In other words, humans engage in cutaneous respiration, in which they absorb a small amount of oxygen through their skin and release carbon dioxide, and all of the carbon dioxide released through the skin is released to the outside through clothing. However, a certain amount of carbon dioxide accumulates between the human body and clothing.
In particular, clothing with low breathability, such as cold-weather clothing such as ski wear, and dust-proof clothing used in IC factories, etc., releases less carbon dioxide to the outside through clothing than normal clothing. Carbon begins to accumulate between the human body and clothing.

[0011] In this way, carbon dioxide accumulates between the human body and clothing, and when the partial pressure of carbon dioxide between the human body and clothing increases, the partial pressure of water vapor between the human body and clothing decreases, and water vapor appears in the form of water droplets between the human body and clothing, and the water droplets generated in this way change the comfort of clothing, and when the concentration of carbon dioxide between the human body and clothing increases, carbon dioxide can conversely reach the skin. It was discovered that the comfort of clothing changes as a result of absorption, leading to the completion of this invention.
