Clothing comfort and water absorbency and retantion of adult incontinence diapers

为了获得与成人失禁尿布的穿着舒适性和吸水性、保水性相关的基础数据，通过改变水刺非织造布的纤维种类、纤维长度、纤维纤度、二次水射流压力、共混比、喷嘴直径和输送带网孔尺寸等工艺参数，研究了水刺非织造布的孔径分布和物理性能。结果表明，这些参数均影响孔径分布和物理性能。我们试图通过使用感官检测方法来评估各种类型的织物的凉爽感。结果表明，该方法对评价织物的凉爽感是非常有用的，织物的凉爽感主要受纤维的吸湿能力的影响，特别是在低含水率的条件下，对于成人失禁尿布的穿着舒适性，尿布材料的压缩特性、表面特性和热传递特性影响穿着舒适性，明确了在尿布含水的情况下这些特性的变化范围。并对所收集的材料进行了测试，看其是否良好，并得出了一个经验方程来估计服装舒适性的触感。并研究了尿布整体的吸水性和保水性对穿着舒适性的影响。虽然整个尿布的饱和含水量是最主要的因素，但纤维间的水与高吸水性树脂中的水的比例也影响服装的舒适性。

The purpose of this study is to gain the basic data related with the clothing comfort and water absorbency and retention of adult incontinence diapers.We examined the pore size distribution and physical properties of spunlace nonwovens made by changing manufacturing parameters such as fiber type, fiber length, fiber denier, secondary water jet pressure, blending ratio, diameter of nozzles and mesh size of conveyer belt. As a result, these all parameters influenced the pore size distribution and physical properties. We attempted to evaluate the cool feeling of various types of fabrics by using a sensory inspection method. As a result, it was found that this method is very useful to evaluate the cool feeling of the absorbent ability of fiber influenced mainly the cool feeling of fabrics especially under the condition as low water content.In regard to the clothing comfort of adult incontinence diapers, it was found that the compression, surface and heat transfer characteristics of diaper materials influenced the clothing comfort, and then we make clear the changing range of these characteristics in the case that diaper included water. And we tested the gather materials to see if it is good or not, and we obtained as an empirical equation to estimate the clothing comfort of the touch feeling.. The effects of water absorbency and retention of the whole diaper on the clothing comfort were investigated also. Though the saturated water content of the whole diaper was the most major factor, the ration of water existed between fibers to water held in super absorbent polymer influenced the clothing comfort also.
