Title
(EN) ELECTRICAL SHIELDING MATERIAL COMPOSED OF METALLIZED STAINLESS STEEL MONOFILAMENT YARN
(FR) MATÉRIAU DE BLINDAGE ÉLECTRIQUE CONSTITUÉ DE FIL MONOFILAMENT EN ACIER INOXYDABLE MÉTALLISÉ
Abstract
(EN)
A yarn or multi-fiber formed of a plurality of micron diameter stainless steel monofilaments which have been rendered more conductive by one or more coatings of electrolytically-deposited metal or metal alloy materials. The metallized yarn provided by the invention has a very low electrical resistance, with consequent benefit in electrical performance, and is particularly useful as an RFI/EMI shielding material.
(FR)
L'invention concerne un fil ou une fibre multiple formée d'une pluralité de monofilaments d'acier inoxydable d'un diamètre de l'ordre du micron et rendus plus conducteurs par une ou plusieurs revêtements d'un métal ou de matériaux d'alliage de métal déposé(s) de manière électrolytique. Le fil métallisé fourni par la présente invention présente une résistance électrique très basse, ce qui augmente sa performance électrique, et est particulièrement utile en tant que matériau de blindage RFI/EMI.
