| Research Abstract |
The purpose of this study is to gain the basic data related with clothing materials for high quality life of aged person and handicapped person.
We examined physical properties of composite nonwovens made by changing structure parameters As reesults, these all parameters influenced physical properties of composite nonwovens, and composite nonwovens could be used for the medical sheet. In regard to water absorbency, we proposed a novel method to identify the kind of fibers by applying the sorptive property, and found that proteins gave high sorptive property of some organic compounds. We also investigated chemical modification of wool fibers for the effective re-use of waste wool and attempted succinylation combined with reduction, oxidation or hydrolysis. As results, succinylation increased water absorbency and hygroscopicity, and accelerates of some effective order components of wool. We evaluated performance of disposable diapers for adults by measuring physical properties and by comparing the measurements and sensory test results. The results show that caluculated NUMERI and THV have high positive correlation with subjective evaluation before wetting. To develop new clothing materials, three approaches were studied. As results, it was suggested the utility of chitosan to make use of its antibacterial properties in the clothing for the aged and handicapped persons, and a very small amount of carbon nanotube was very helpful to reduce the static electricity.
