Patent abstract
A cleaning sheet (1) includes at least one continuous-filament aggregate (10) formed by aggregating and orienting a multitude of continuous filaments (11) substantially in one orientation direction. The continuous filaments (11) are joined by a single first joining line (12) extending continuously in a direction orthogonal to the orientation direction of the continuous filaments (11) and are joined by a plurality of second joining lines (13) extending in the orientation direction. In this way, the continuous filaments (11) in the continuous-filament aggregate (10) are kept in an aggregated state. Preferably, the second joining lines (13) are connected to the first joining line (12).
