    摘要: A water disintegratable non-woven fabric having excellent water disintegratability and high wet strength can be obtained by a step of forming a fiber web from fibers having a fiber length of 10 mm or less, a step of applying a water jet treatment to the fiber web to obtain a fiber sheet having wet strength of less than 100 g/25 mm in MD and CD, the wet strength being defined by tensile strength at break of the fiber sheet, as measured by using a tensilon tester with a chuck distance of 100 mm, at a tensile speed of 100 mm/min to the fiber sheet which is cut into 25 mm width and 150 mm length and impregnated with water in an amount 2.5 times the weight of the fiber sheet, and a step of adding at least one binder selected from the group consisting of carboxymethyl cellulose, alkylcellulose, polyvinyl alcohol and modified polyvinyl alcohol to the fiber sheet. The water disintegratable non-woven fabric is sufficiently bulky and has an excellent wiping effect.

    摘要: After laminating together the first sheets crepe-processed at a high crepe ratio and the second sheet crepe-processed at a crepe ratio lower than that of the first sheet or not crepe-processed, the sheets are bonded together at bonding parts at a given pitch in rows. When the resulting bonded sheets are impregnated with a liquid, expansions are generated between the rows of bonding parts due to the difference in ratios of the elongation of the two sheets. The expansions take on the shape of large wrinkle according to the pitch of the bonding parts. At the production process of the sheet, the sheet is crepe-processed containing water at a preset ratio, whereby small wrinkles as residual crepe wrinkles are formed on the sheet surface. The large wrinkles and the small wrinkles can enhance the wiping effect.

    摘要: Conventional water-decomposable fibrous sheets for cleaning sheets capable of being disposed of in toilets and others do not have well-balanced decomposability in water and strength. The water-decomposable fibrous sheet containing from 5 to 100% by mass of fibrillated rayon having a fiber length of at most 10 mm and having a degree of beating of at most 700 cc, optionally along with other fibers having a length of at most 10 mm, has good decomposability in water and high wet strength. When subjected to water-jetting treatment, it becomes more bulky to have a soft feel.

    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.
