Abstract
Super absorbent polymer (SAP) and fluff pulp were used as absorbing materials, and the different SAP mass ratio and fluff pulp were applied to paper diaper absorption core layer. Then, the influence of different SAP/fluff pulp in composite core layer on the paper diapers normal saline absorption rate and topsheet run-off were studied. Results showed that SAP has a significant effect on normal saline absorbency respect to fluff pulp. When the normal saline volume increased, the paper diapers absorption rate about normal saline decreased, while the topsheet run-off increased. When the SAP mass ratio to fluff pulp was 0.5:0.5, the liquid absorbency rate was 35.23 g/g, the paper diaper average absorption rate was 3.96 mL/s, and the biggest topsheet run-off was 13.25 g.
