Patent

CA 2386389

The invention relates to a heel lining for use in the shoe industry comprising a polymer impregnated non-woven having a surface area weight of 180 to 350 g/m2 and a tear strength of > 15 N in a longitudinal and a perpendicular direction. The non-woven consists of melt spun, aerodynamically stretched multi-component endless filaments which are arranged directly to form a non- woven. Said non-woven has a titer of < 2 dtex. The multi-component endless filaments are split and hardened when said filaments have attained a pre- defined strength of 90 % of the supermicro-endless filaments, i.e. a titer of < 0.2 dtex.

L'invention concerne une doublure de talon pour l'industrie de la chaussure, réalisée dans un matériau composé d'un non-tissé imprégné d'un polymère, présentant un grammage de 180 à 350 g/m?2¿, et une résistance au déchirement dans le sens longitudinal et transversal >15N. Ce non-tissé est composé de filaments sans fin à plusieurs composants filés à chaud, étirés aérodynamiquement, et disposés en tant que non-tissé avec un titre <2 dtex, ces filaments sans fin à plusieurs composants étant séparés et encollés à au moins 90 %, après pré-encollage, pour obtenir des supermicro-filaments sans fin avec un titre <2 dtex.
