Abstract
A scrubbing-brush is manufactured by the following process. First, a number of nets formed of fibers connected with one another are secured. The bundle is bundled at an intermediate portion thereof by a bundling member. Then, the bundle is cut at opposite sides of the bundling member. The thus cut bundle is then heated to cause memory deformation of the fibers, thus completing a scrubbing-brush. The thus finished scrubbing-brush has a number of fibers having respective ends formed with smooth convex bristle surfaces.
