WATER-DISINTEGRATABLE FIBROUS SHEET CONTAINING FIBERS HAVINGDIFFERENT FIBER LENGTHS AND PROCESS FOR PRODUCING THE SAME |
摘要 |
A water-disintegratable fibrous sheet comprising a web of fibers comprising pulp of hardwood and pulp of conifer, pulp of conifer having a fiber length longer than that of the pulp of hardwood, and a water-insoluble or water-swellable binder being contained in the web to bind the fibers, is disclosed. The fibrous sheet is excellent in water-disintegratability and has sufficient strength for withstanding practical use. Furthermore, since excellent water-disintegratability and strength can be obtained without using a water-soluble binder, a production process of the fibrous sheet can be made simple.
