The present invention is related to an abrasive cleaning article, made of spread abrasive particles and microencapsulated particles of an aromatizing substance contained in urea-formaldehyde walls, through a three-dimensional non-woven web of fiber that are bonded to the web by a resin adhesive. The item, of any geometric shape, offers the user a sensation of cleanliness due to the constant presence of a "fresh" scent associated to the fiber; the scent remains during the whole life of the abrasive item since the microcapsules break partially during the normal use of the item. The invention also refers to the production process of such abrasive item.
L'invention se rapporte à un article abrasif permettant de nettoyer et composé de particules abrasives dispersées et de particules microencapsulées d'une substance aromatisante contenue dans des parois de l'urée formaldéhyde, à travers un réseau tridimensionnel de fibres non tissées, adhérant à celui-ci par un adhésif résineux. L'article, dont la forme géométrique peut être quelconque, offre à l'utilisateur une sensation de nettoyage en raison de la présence constante d'un arôme "frais" associé à l'article. Cet arôme est préservé pendant toute la vie utile de l'article abrasif grâce à la rupture partielle des microcapsules résultant de l'utilisation normale de l'article. L'invention se réfère également au procédé d'obtention dudit article abrasif.
