Effect of Pulp and SAP Characteristics on Absorption in Hygienic Disposables, 1990 Nonwovens Conference Proceedings
Disposable diapers have caused environmental concerns because of their volume in landfills- Since fluff pulp cores are the largest and costliest element in these products, there is a strong interest in core source reduction. The work reported here was aimed at defining which system parameters most influenced fluid absorption in bonded fluff pulp cores containing super absorbent polymers. These structures hold good potential for source reduction. Laboratory fluff pulp pads were thermally bonded with a polyolefin pulp and their fluid absorption and retention characteristics were determined. Pad density had the greatest influence on absorption followed by SAP concentration. Low density pads showed the greatest absorption and retention. Cores with low cross link density SAP’s showed modestly better retention than those with high cross link density SAP’s.
