Patent number: 5525397Abstract: A cleaning sheet comprises a network sheet and a nonwoven fiber aggregate formed by the entanglement of fibers of a fiber web and disposed on at least one side of the network sheet. The fibers of the nonwoven fiber aggregate are further entangled with the network sheet, forming a unitary body. The cleaning sheet has the breaking strength of 500 g/30 mm or more, and the elongation at a load of 500 g/30 mm is 10% or less. The fiber aggregate has the entanglement coefficient of from 10 to 500 m. The entanglement coefficient is expressed by the initial gradient of the stress-strain curve measured with respect to the direction perpendicular to the fiber orientation in the fiber aggregate.Type: GrantFiled: December 8, 1994Date of Patent: June 11, 1996Assignee: Kao CorporationInventors: Akihito Shizuno, Hiroyuki Yanagida
