Abstract

L'invention concerne un textile chauffable (6), tissé ou entrelacé à partir d'au moins un filament fin (1), contenant au moins une fibre (2 ; 4) en plastique et/ou à base d'un matériau naturel, enduit d'un matériau électriquement conducteur (3) et/ou enroulé avec une fibre électriquement conductrice (5). Le textile (6) selon l'invention convient notamment pour les couvertures chauffantes, les coussins chauffants, les surmatelas, les coussins, les vêtements, tels que les vestes ou les T-shirts, les chancelières, les doudous ou autres textiles destinés à réchauffer des parties du corps. Le textile chauffable peut atteindre de préférence une température comprise entre 30 et 100 degrés Celsius, de préférence entre 36 et 65 degrés Celsius. En outre, le textile selon l'invention peut être combiné en une structure monocouche ou multicouche, selon l'application, avec des feuilles de réflexion de la chaleur et/ou des matériaux de rembourrage.
