A RESEARCH ON THE BREATHABILITY PROPERTY OF BABY DIAPER BACKSHEET

Disposable breathable diapers are considered as one of the most important developments in diaper sector. Breathable diapers keep the child’s skin dry and provide a comfortable feeling to the child. Breathability of diapers is obtained by using the breathable back sheet layer which is the most outer layer that the diaper comprises. In this study, the effects of laminating and printing processes on back sheet material breathability are studied. For this aim, four types of back sheet samples namely; film, printed film, laminated film and printedlaminated film are tested for breathability. For breathability testing, water vapour permeability test was applied with two different test devices which principally operate in different ambient conditions. As a result of the study, it is seen that, the breathability of back sheet component decreases as a result of printing and laminating processes. Also, it can be concluded that the ambient conditions for standard textile fabrics is not convenient for testing back sheet samples. Since, the test does not simulate the real ambient conditions of microclimate between the diaper and the child’s skin during diaper use.
