Research progress on the evaluation of thermal and moisture comfort of disposable diapers for babies

Abstract

In order to further improve evaluation of baby disposable diapers and optimize product design, as well as enhance thermal and moisture comfort and safety of the baby, heat and moisture transfer mechanisms in the wearing state of diapers were analysed, and current evaluation technologies of diaper's thermal and moisture comfort were summarized from material and product perspectives. In view of current problems, the following suggestions were proposed for improvement: 1) It is necessary to pay attention to the effects of changes after urine absorption in properties of diaper materials and the dynamic changes in size of the micro-space underneath the diaper on thermal and moisture comfort; 2) Experiments for evaluation need to be closer to life scene and the manikin system needs to be standardized; 3) In order to predict skin health of babies in the future research, correlation between thermal and moisture comfort and skin damage needs to be established.
