A bi-functional nonwoven fabric wipe (10) embodying the principles of the present invention comprises a hydroentangled, composite fibrous matrix having first and second, opposite expansive surfaces. The first expansive surface of the wipe is provided by a first outer layer (12) of the composite fibrous matrix, with this surface exhibiting a relatively soft, smooth surface texture. In contrast, the second, expansive surface is provided by a second outer layer (14) of the composite fibrous matrix, and exhibits a relatively abrasive surface texture. By the differing surface textures of the opposite expansive surfaces, the present wipe is provided with bi-functional characteristics, thus enhancing versatile use for cleaning applications.
L'invention concerne un tampon de nettoyage non tissé bifonctionnel comprenant une matrice composite de fibres entremêlées par procédé hydraulique possédant une première surface expansive et une seconde surface expansive opposées. La première surface expansive du tampon est constituée par une première couche extérieure de la matrice composite fibreuse, présentant une texture de surface relativement souple et uniforme. En contraste, la seconde surface expansive est constituée par une seconde couche extérieure de la matrice composite fibreuse, et présente une texture de surface relativement abrasive. Grâce aux textures de surface différentes des surfaces expansives opposées, le tampon de la présente invention présente des caractéristiques bifonctionnelles, facilitant ainsi une utilisation polyvalente dans les applications de nettoyage.
