Abstract
This article described a study on the gelβforming abilities of a number of different types of alginate fibers. The gelling abilities were assessed through the measurement on the release of calcium ions from the fibers and the absorption capacities in water and 0.9% saline solution. The effects of the chemical compositions of the alginate and the calcium and sodium contents of the fibers on the gelling abilities were studied. Β© 2003 Wiley Periodicals, Inc.

The swelling behaviour and elastic properties of gelatin gels are reported. Ampholytic swelling properties have been investigated. Antipolyelectrolyte performance is observed when gels are swollen in di β erent salt solutions. Swelling behaviour in high salt solutions is di β erent from that in low sa
The equilibrium and viscoelastic properties of alginate gel crosslinked with Ca 2+ were determined as a function of alginate concentration and duration of exposure to physiologic concentrations of NaCl. Compressive and shear stress relaxation tests and oscillatory shear tests were performed to measu
