A cleaning element includes a fiber assembly having a plurality of fibers extending in a predetermined direction and a nonwoven fabric provided on the fiber assembly. A first fusion bonded part extends in a cross direction traversing the predetermined direction to fusion-bond the fiber assembly and the nonwoven fabric, and a plurality of second fusion bonded parts is provided discontinuously in the cross direction to fusion-bond the fiber assembly and the nonwoven fabric. Each of the second fusion bonded parts has a first area and a second area. A length in the predetermined direction from the first fusion bonded part to the first area is different from a length in the predetermined direction from the first fusion bonded part to the second area.

Cleaning element and cleaning tool

It is an object of the present invention to provide effective technique for a higher cleaning effect and higher operability of a cleaning element. According to the representative cleaning element, a distance dbetween adjacent ones of the fusion bonded partsis longer than a length dor dformed on both of the pair adjacent fusion bonded partsandin the respective longitudinal end regions of the cleaning element.

A cleaning tool comprises a cleaning body having such a layer structure that non-woven fabrics and fiber bundles are laminated onto each other. In the cleaning body, a hardening treatment is applied to the fiber bundles disposed in the storage space of a cylindrical part in which the holding part of a holder is stored.

A cleaning tool comprises a cleaning body in which non-woven fabrics and fiber bundles are laminated onto each other. In the cleaning body, the fiber bundles disposed on the outer surface of a cylindrical part in which the holding part of a holder is stored include fiber extending areas in which a plurality of fibers extend parallel with each other in a predetermined direction. These fiber extending areas form a second cleaning portion.

It is an object of the invention to provide an effective technique for realizing a higher cleaning effect in a cleaning tool having a sheet-type cleaning element for wiping an object to be cleaned. According to a representative cleaning element, the sheet pieces () of a cleaning side sheet () have a smaller width in a longitudinal direction than the sheet pieces () of an upper face side sheet ().

A cleaning element includes a fiber assembly having a plurality of fibers extending in a predetermined direction and a nonwoven fabric disposed on the fiber assembly. A first fusion bonded part extends in a cross direction crossing the predetermined direction to fusion bond the fiber assembly and the nonwoven fabric, and a plurality of second fusion bonded parts formed discontinuously in the cross direction at a lateral side of the first fusion bonded part to fusion bond the fiber assembly and the nonwoven fabric. The first fusion bonded part extends all the way through the fiber assembly in a thickness direction of the cleaning element. The plurality of second fusion bonded parts extend only a part of said fiber assembly in the thickness direction.

It is an object of the present invention to provide effective technique for a higher cleaning effect and higher operability of a cleaning element. According to the representative cleaning element, a distance dbetween adjacent ones of the fusion bonded parts is longer than a length dor dformed on both of the pair adjacent fusion bonded parts and in the respective longitudinal end regions of the cleaning element.

It is an object of the present invention to provide effective technique for a higher cleaning effect and higher operability of a cleaning element. According to a representative cleaning tool, bonding thickness of the fusion bonded partin a thickness direction of the cleaning elementof the cleaning toolis smaller than the bonding thickness of the fusion bonded part

It is an object of the present invention to provide effective technique for a higher cleaning effect and higher operability of a cleaning element. Representative cleaning element includes a fusion bonded part having a curved portion to project to the holding space.

The present invention provides an indoor cleaning tool having a dry fibrous base material. An antigenicity-reducing composition that includes an antigenicity-reducing component, a lubricant, and a surfactant is applied to the fibrous base material. It would be preferable for the antigenicity-reducing component to be tannic acid.

Cleaning tool

An indoor cleaning tool having a dry fibrous base material is provided. An antigenicity-reducing composition including an antigenicity-reducing component, an oil and a surfactant are applied to the fibrous base material. Preferably, the antigenicity-reducing component is an extract of anor aplant extracted with water or an organic solvent.

A cleaning implement includes a cleaning head having on a bottom a cleaning operation surface, a holding portion arranged on the side opposite the cleaning head, a pipe for coupling the cleaning head and the holding portion, and a valve opening and closing device provided to the pipe so as to be able to hold a first container for receiving a first fluid or a second container for receiving a second fluid. The holding portion includes a lever coupled to the valve opening and closing device so as to open and close a first valve of the first container or a second valve of the second container. A spout of a second ejection nozzle for ejecting the second fluid containing an allergen inactivator is located, for example, at a height of about 30 cm or more from the floor.

Cleaning implement

There is disclosed a cleaning article including a brush portion. The brush portion has a plurality of strips and at least one layer of a fiber bundle.
