Abstract: By removing burrs of the pin of the card clothing used in the slicker brush, and by giving a rounded distal ends, the feeling of use and safety of the slicker brush are improved, and removal of hair after use is facilitated. The method includes: a first process of implanting a plurality of pins made of metal wire on a base clothing to produce a card clothing; and a second process of polishing each pin of the card clothing, using a polishing material having flexibility and elasticity, in which in the second process, polishing is performed by rubbing, while pressing the polishing material against each of the pins, thereby manufacturing a card clothing having a rounded distal ends with no burr.
