Abstract
A water-disintegrable cleaning sheet comprising a web of water-dispersible fibers having incorporated thereinto a water-soluble binder having a carboxyl group; at least one metallic ion selected from the group consisting of ions of alkaline earth metals, manganese, zinc, cobalt, and nickel; and an aqueous cleaning agent containing an organic solvent, is disclosed. The sheet satisfies both water disintegrability and strength even when cotained a cleaning agent of high water content.
Claims13
A water-disintegratable cleaning sheet comprising a web of water-dispersible fibers selected from the group consisting of wood pulp fibers, non-wood vegetable fibers, rayon fibers, and polyester fibers, having incorporated thereinto a water-soluble binder having a carboxyl group that is selected from the group consisting of carboxyl group containing polysaccharide derivatives, synthetic polymers of unsaturated carboxylic acid monomers, and alginic acid in an amount from 0.1 to 30% by weight based on the dry wight of said web;
- at least one metallic ion selected from the group consisting of ions of alkaline earth metals, manganese, zinc, cobalt, and nickel, in an amount of at least 1/4 mol per mol of the carboxyl group of said water-soluble binder;
- and an aqueous cleaning agent containing an organic solvent which comprises an organic solvent in an amount ranging from 5 to 95% by weight, and water in an amount ranging from 95 to 5% by weight.
