Abstract

La présente invention concerne un outil de nettoyage, une feuille de nettoyage et un procédé d'enlèvement des débris, des peluches, ou des cheveux de diverses surfaces. Selon l'invention, l'outil de nettoyage comporte un premier réseau de tiges et un deuxième réseau de tiges, le premier réseau de tiges étant plus petit et plus dense sur une surface de l'outil de nettoyage. Les tiges plus grandes sont capables de desserrer et de tirer les cheveux enfoncés profondément dans les surfaces textiles lâches, alors que les tiges plus petites sont capables de saisir et de retenir les cheveux détachés.
