Abstract
The pore fractal dimensions of PVA/PAA-AM blend superabsorbent fiber were calculated by box-counting method. The results indicate that the pore structures of superabsorbent fiber have obvious fractal characteristics. In addition, we have also studied the relations of AM ratio with other parameters. Calculation shows that the addition of appropriate amount of AM can increase the porosity of superabsorbent fibers and improve its absorption ability.
