Summary: | A security yarn which is inconspicuous, prevents from being removed, can be attached to an article having a shape that conventionally refuses the attaching, and is expanded in range of applications, the yarn comprising; a core material consisting of a soft magnetic fiber (1) or a soft magnetic fiber and a wadding (4), and cover materials (2, 3) each consisting of a non-metallic material for convering the core material; a core material consisting of a soft magnetic fiber or a soft magnetic fiber and a wadding, and a semi-hard magnetic material (10) covered with a cover material; or a core material consisting of a soft magnetic fiber or a soft magnetic fiber and a wadding, and a fusion-deposition fiber (9) covered with a cover material.
L'invention concerne un fil de sécurité non apparent, que l'on ne peut pas retirer, susceptible d'être fixé sur un article dont la forme ne se prête généralement pas à la fixation d'un tel fil, et dont l'éventail d'applications est large. Le fil est composé de la manière suivante : coeur en fibre magnétique molle (1) ou en fibre magnétique molle avec matière de ouatage (4), et matériaux de revêtement (2, 3) comprenant chacun un élément non métallique, recouvrant le coeur; coeur en fibre magnétique molle ou en fibre magnétique molle avec matière de ouatage, et matériau magnétique semi-dur (10) recouvert d'un matériau de revêtement; ou bien coeur en fibre magnétique molle ou en fibre magnétique molle avec matière de ouatage, et fibre à fusion-déposition (9) recouverte d'un matériau de revêtement. |
