A water absorber for absorbing and removing water remaining on floors resulting fromnleakage or flooding, and comprising a water-permeable casing made of cotton cloth filled withnan antibacterial water-absorbing agent comprised of a modified polymer compound. The waternabsorber absorbs water to swell. The water absorber is filled with the antibacterialnwater-absorbing agent, and therefore, even after absorbing water, the water absorber is notnunder unsanitary conditions such that bacteria propagate. When the water absorber is dried,nit regains water-absorbing property and can be reused as a water absorber. The antibacterialnwater-absorbing agent (modified polymer compound) is produced by subjecting to acidntreatment and metal-salt forming treatment a scrap material of typical organic resins, such asnan ABS resin, and has a nitrile group, a hydrolysis product of the nitrile group, and an acidngroup introduced as a substituent in the form of a metal salt. |
