Researching on Baby Diaper Performance with 3D Absorbent Layer

Abstract

Disposable diaper manufacturers have focused on absorbent zone layers as a way to ensure consumers achieve optimum comfort and minimize the environmental impact of products. The producers who want to achieve the desired performance values in the absorbent core layers have been investigated the amounts / mixing ratios of raw materials such as superabsorbent polymer (SAP) and wood pulp (pulp) or their distribution on the absorbent layer. When the absorbent core layers consisting of homogeneous SAP / pulp mixtures are examined in the current diapers, it is seen that the urine is concentrated in the middle section and this amount decreases towards the front and back parts of the diaper. It can be said that the SAP / pulp mixtures, which are sectionally evenly distributed in the absorbent zone layer, are used less in the front and rear sections, that is, the absorbent layer has a 3D structure. It can be said that the SAP/pulp mixtures, which are distributed sectionally on the absorbent layer, are absorbed more intensely in the middle region, so the amount in the front and back parts has less effect on the performance of the diaper. When the diaper machines currently in our company were examined, it was seen that it has not be possible to produce diapers with a 3D absorbent zone layer. In this study the effect of transferring some of the SAP/pulp mixtures homogeneously distributed in the absorbent layer from the back sections to the center of the core section on the diaper performance was investigated with the 3D mold system designed in our company. As result of the tested diapers, it was observed that the performance of the product increased or remained constant by moving the SAP / pulp mixes moved behind the absorbent layer to the center of the core layer. At the same time, it can be said that it is a cost-reducing work since raw materials that are not used in the front and back sections are saved.
