摘要或動機

In this project, the stem of the banana tree is innovated into the absorbent substance in the baby’s diapers. A water proof material too has been innovated . In the study carried out, several changes has been identified in the production of an environment friendly disposable diapers.The structure of water molecules and cellulose as well as charges in both materials will enable cellulose present in all green plants to absorb water easily and effectively. Cellulose is also insoluble in water or solvent. This project uses the banana stem due to its high cellulose content and furthermore the cellulose present has a very fine structure which will increase its absorbency rate. Baby’s urine will be absorb into the absorbent material through capillary actions due to surface tension that develops between the cellulose and baby’s urine. The absorbent substance in baby’s diapers available today in the market is made up of Polyacrilate (SAP) and cellulose which are extracted from hardwoods, particularly pine trees. The production of the absorbent substance from the cellulose will help to reduce the logging of hardwoods.
