ADVANCED ACQUISITION LAYERS FROM ENHANCED CELLULOSE FIBERS

摘要

The development of diaper structures over the years has several benchmark breakthrough technologies. These include the initial disposable diaper structure based on layers of tissue wadding; fluff pulp; hydrophobic coverstock materials; superabsorbent development and placement; leg cuffs, and others. The defining technology for fluid acquisition enhancement was the development and application of superabsorbent systems for ultrathin diapers. This allowed the diaper manufacturer to utilize a more efficient fluid storage material (in terms of cost per gram absorption), produced a much smaller packaged unit, and allowed the retailer to dramatically increase return on shelf space. However, the technology also provided a significant challenge to ensure that fluid insults could be taken into the core at a rate high enough to avoid leakage problems while providing enough liquid spreading to utilize the costly storage core.
