Patent attributes
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.
