The aim of this study was to propose the assessment for diapers on the bases of the required clothing ventilation. The tracer gas method allowed the detection of small changes in clothing ventilation of diapers due to urine loading in this experiments and three types of diapers, which were 3 brands for newborn babies, 5 brands for babies and 15 brands for elderly people, were tested.The clothing ventilation decreased, and whereas the wetted area increased with the urine load in all brands. Comparing the brands in each type of diapers, significant differences in the clothing ventilation and the wetted area were found. A significant negative correlation was found between the wetted area and the clothing ventilation in each brand, which suggested that the brands with a smaller wetted area could have provided greater ventilation. However, the relationship among some brands in terms of the clothing ventilation was not consistent with that assumption in terms of the wetted area. Furthermore, the slope of regression line between the wetted area and the clothing ventilation varied among some brands. These conflicts show the assessment on the bases of the required clothing ventilation (RCV) is necessary in order to examining the microclimate humidity inside diapers. RCV was estimated from the evaporated water per unit area, the wetted area and the difference of absolute humidity between inside and outside diaper in absorbed diapers. The ratios of the experimental values in clothing ventilation to RCV have a quantitative evaluation of absorbed diaper.

这项研究的目的是在所需的服装通风基础上提出尿布的评估。示踪气体方法允许在该实验中尿液加载和三种类型的尿布引起的尿布的服装通风较小，这是新生婴儿的3个品牌，5个婴儿品牌和15个老年人品牌的品牌。比较每种类型的尿布中的品牌，发现衣物通风和湿区的显着差异。在每个品牌的润湿区域和服装通风之间发现了显着的负相关，这表明具有较小湿润区域的品牌可能会提供更大的通风。但是，某些品牌在服装通风方面之间的关系与湿区域的假设不一致。此外，一些品牌之间的湿区和衣服通风之间的回归线斜率各不相同。这些冲突表明，为了检查尿布内部的微气候湿度，必须进行所需服装通风（RCV）基础的评估。从单位面积蒸发的水，湿面积和吸收尿布内部和外部尿布之间的绝对湿度差异估计RCV。服装通风中实验值与RCV的实验值之比具有对吸收尿布的定量评估。
