Abstract:
1. A cleaning element, having a fiber bundle and a non-woven fabric laminated together, comprising: a long tubular part which is formed into a tubular shape by folding back the cleaning element such that the non-woven fabric of the cleaning element is located inside, a receiving space which is defined inside the tubular part and in which a holding part for holding the cleaning element is removably received, and a brush part which forms a brush-like cleaning area in a region of the cleaning element other than the tubular part, wherein the fiber bundle is one of i) a single fiber structure formed by fibers of twist yarn, yarn, or yarn to which a plurality of filaments are partially connected, which fibers are aligned in at least one of a length direction and a radial direction, and ii) an assembly of such fiber structures, and the fiber bundle is disposed on an outer surface of the tubular part and includes a fiber extending region in which the fibers extend parallel in a predetermined direction, and the fiber extending region forms a second cleaning area other than the brush part, the fiber bundle and the non-woven fabric are fusion bonded together in a zig-zag fusion bonded pattern that is exclusively provided over the receiving space and consists of bonding lines that extend to and between a pair of parallel fusion bonding lines that are parallel to the receiving space and near a central portion of the cleaning element, and a plurality of cuts are formed in the fiber bundle between the pair of fusion bonding lines and the zig-zag bonded pattern.
