Des revêtements pour solidariser des articles épars tels que des fils métalliques, des câbles ou des tubes sont généralement connus dans la technique. Ces revêtements protecteurs comprennent des revêtements ondulés, des revêtements tressés et des revêtements textiles. Jusqu'à présent, chacun de ces types de gaines tubulaires était conçu pour une fonction donnée et se comportait particulièrement bien pour cette fonction donnée, notamment une résistance à l'abrasion, un retard de flamme, des températures élevées ou une protection contre les interférences électromagnétiques. Cependant, beaucoup des modèles de gaines tubulaires exigent une fabrication spécifique pour leur application donnée. En conséquence, il existe un besoin d'un moyen courant ou universel de fabrication d'une gaine tubulaire dans laquelle les fils se trouvant à l'intérieur de la gaine sont remplacés, combinés ou échangés en se basant sur une application donnée.Coatings for securing loose articles such as wires, cables, or tubes are generally known in the art.

Dans une troisième forme de réalisation de l'invention, un fil monofilamentaire de poly(sulfure de phénylène) est utilisé conjointement avec un fil mixte texturé Nomex®/Basofil®, c'est à dire un filament composite à hautes caractéristiques de tenue à la flamme, à la chaleur et à l'abrasion, pour obtenir une gaine tubulaire à température élevée résistant à l'abrasion. Dans une quatrième forme de réalisation, un monofilament de polyamide est utilisé conjointement avec une série de fils mixtes d'acier inoxydable et de polyester et de fils multifilamentaires de polyester pour former une gaine tubulaire protégée résistant à l'abrasion.Accordingly, the present invention is directed to an abrasion-resistant tubular sheath having a monofilament forming a first weft in the textile web, a first multifilament yarn forming a second weft in the textile web, and a set of crocheted chains comprising a plurality of yarns. textured multifilament forming a chain-stitch ply in the textile fabric. The textile fabric is crocheted in a flat configuration and then shaped by an operation of thermofixing in elastic tubular sheath.
