Abstract

MATERIAL FILTRANTE PLISSADO PARA ARTIGOS DE FUMO. A presente invenção refere-se a um material filtrante para produzir um segmento para um artigo de fumo, em que o material filtrante inclui um tecido não tecido hidroemaranhado, e o tecido não tecido inclui fibras, sendo que as fibras são selecionadas do grupo que consiste de fibras de celulose, fibras de celulose regenerada e misturas das mesmas, e estas fibras juntas são contidas em uma quantidade de no mínimo 50% e no máximo 100% da massa do tecido não tecido hidroemaranhado no tecido não tecido, e sendo que o tecido não tecido tem um formato de tira, que apresenta um sentido longitudinal no sentido do movimento da tira, para este ortogonal um sentido transversal situado no nível da tira e um sentido da espessura ortogonal para o sentido longitudinal e sentido transversal. O tecido não tecido é formado de tal maneira, que ele apresenta, no nível estendido em do sentido transversal e sentido da espessura, uma estrutura de onda com uma altura da onda de no mínimo 50 µm e no máximo 1000 µm, assim como um comprimento da onda de no mínimo 150 µm e no máximo 5000 µm.PLEATED FILTERING MATERIAL FOR SMOKING ARTICLES. The present invention relates to a filter material for producing a segment for a smoking article, wherein the filter material includes a hydroentangled nonwoven fabric, and the nonwoven fabric includes fibers, the fibers being selected from the group consisting of of cellulose fibers, regenerated cellulose fibers and mixtures thereof, and these fibers together are contained in an amount of at least 50% and at most 100% of the mass of the hydroentangled nonwoven fabric in the nonwoven fabric, and wherein the fabric The nonwoven has a strip format, which has a longitudinal direction in the direction of movement of the strip, for this orthogonal a transverse direction located at the level of the strip and an orthogonal thickness direction for the longitudinal direction and transverse direction. The non-woven fabric is formed in such a way that it has, at the level extended in the transverse direction and the thickness direction, a wave structure with a wave height of at least 50 µm and a maximum of 1000 µm, as well as a wave length wave length of at least 150 µm and at most 5000 µm.
