Abstract

"MéTODO DE PRODUZIR UM MATERIAL NãO TECIDO". A presente invenção se refere a um método de produzir um material não tecido, compreendendo a formação de uma manta de filamentos contínuos sobre um membro de formação (12) e aplicação sobre os filamentos contínuos de uma dispersão de fibras, formada por via úmida ou por espuma, contendo fibras naturais e/ou fibras sintéticas curtas. Desta maneira, forma-se uma manta fibrosa que contém filamentos contínuos e fibras naturais e/ou fibras curtas sintéticas, e subsequentemente a manta é hidroentrelaçada de maneira a formar um material não tecido. Aplica-se umidade à manta de filamentos contínuos à baixa pressão antes de depositar a dispersão de fibras formada por via úmida ou por espuma sobre a manta de filamentos contínuos, evitando assim qualquer ligação substancial entre os filamentos da manta."METHOD OF PRODUCING NON-WOVEN MATERIAL". The present invention relates to a method of producing a nonwoven material comprising forming a continuous filament mat over a forming member (12) and applying to the continuous filaments a wet or wet formed fiber dispersion. foam containing natural fibers and / or short synthetic fibers. In this manner, a fibrous mat is formed which contains continuous filaments and natural fibers and / or synthetic short fibers, and subsequently the mat is hydroentangled to form a nonwoven material. Moisture is applied to the continuous pressure filament mat at low pressure before depositing the wet or foam dispersion of fibers onto the continuous filament mat, thus avoiding any substantial bonding between the filaments of the mat.
