Abstract
(EN)
A thermoplastic synthetic fiber nonwoven fabric which has a weight of 7 to 50 g/m2, an average fiber diameter of 7 to 40 μm, a partial heat contact bonding percentage of 5 to 30 %, a delustering agent content of 0.5 wt % or less; or a laminated nonwoven fabric characterized in that it comprises the thermoplastic synthetic fiber nonwoven fabric as a primary component and has a maximum opening diameter of 200 to 2000 μm, a transparency of 50 % or higher, a powder leak percentage of 10 wt % or less, and a value representing the hydrophilicity thereof of less than 10 seconds; a tea bag using the nonwoven fabric.
(FR)
L'invention concerne un non-tissé en fibre synthétique thermoplastique présentant un poids compris entre 7 et 50g/m2, un diamètre moyen de la fibre compris entre 7 et 40$g(m)m, un pourcentage de liaison par contact de chaleur partiel compris entre 5 et 30 %, une teneur en agent de matage égale ou inférieure à 0,5 % en poids. L'invention concerne également un non-tissé laminé présentant la caractéristique de comprendre un non-tissé en fibre synthétique thermoplastique en tant que constituant principal, et de présenter un diamètre d'ouverture maximum de 200 à 2000$g(m)m, une transparence égale ou supérieure à 50 %, un pourcentage de fuite de poudre égal ou inférieur à 10 % en poids, et une valeur représentant la capacité hydrophile égale ou inférieure à 10 secondes. Cette invention concerne également un sachet de thé utilisant un tel non-tissé.
