Abstract:
1. A cleaning sheet comprising: a hydrophobic first nonwoven fabric sheet, a hydrophobic second nonwoven fabric sheet and a hydrophilic impregnated element impregnated with cleaning solution, the impregnated element being disposed between the first nonwoven sheet and the second nonwoven sheet, wherein the first nonwoven fabric sheet and the second nonwoven fabric sheet are integrated to each other with the impregnated element disposed between the first and second nonwoven fabric sheets, wherein: the first nonwoven fabric sheet has a fusion bonded layer provided at a side of the first nonwoven fabric sheet facing the impregnated element which fusion bonded layer controls the amount of release of cleaning solution of the impregnated element from the outer surface of the first nonwoven fabric sheet, the first nonwoven fabric sheet is provided with fibers containing thermoplastic fibers and thermoplastic fibers provided on the side of the first nonwoven fabric sheet facing the impregnated element has a lower melting point than thermoplastic fibers provided on the sides opposite from the sides facing the impregnated element, whereby the fusion bonded layer is provided at a side of the first nonwoven fabric sheet facing the impregnated element, the second nonwoven fabric sheet also has a fusion bonded layer provided at a side facing the impregnated element and the fusion bonded layer of the second nonwoven fabric sheet controls the amount of release of cleaning solution of the impregnated element from the outer surface of the second nonwoven fabric sheet, and the second nonwoven fabric sheets is provided with fibers containing thermoplastic fibers and thermoplastic fibers provided on the side of the second nonwoven fabric sheet facing the impregnated element has a lower melting point than thermoplastic fibers provided on the sides opposite from the sides facing the impregnated element, whereby the fusion bonded layer is provided at a side of the second nonwoven fabric sheet facing the impregnated element.
