Definitions

• the present invention relates to a fire-resistant textile yarn comprising an inorganic filament core surrounded by fibers formed at least in part of aramid resin, the title of the yarn being between 30-55 tex, the proportion by mass of the core being between 10% and 30%, the aramid fibers being spun around this core free from axial torsion.
• This invention also relates to a use of this wire.
• the subject of this invention is first of all a fire-resistant textile yarn according to claim 1, and then a use of this yarn according to claim 7.
• This textile yarn exhibits better abrasion resistance, the fibers adhering better to the core constituted by a multi-filament twist than to a mono-filament.
• the breaking strength as well as the regularity of breaking strength are also improved.
• the manufacture of the thread which is the subject of the invention with a thin core which is not twisted axially during the spinning of the fibers which covers it is carried out by a process known under the name of Dref III, implemented by a spinning loom from the house of FEHRER. . According to this process, the fibers are wound around the core, which therefore does not undergo axial twisting as in conventional spinning processes. It is therefore possible to use a twisted glass monofilament which, for a thread of 30 to 55 tex represents between 10% and 30% by weight of this thread.
• Dref III makes it possible to obtain thinner wires than those manufactured on a Dref II system, since the machine Dref III allows the spinning of threads up to 36 tex and even up to 20 tex for the spinning of long fibers.
• a 50 tex yarn was produced comprising a glass core formed by a twisted pair of 2 ⁇ 5.5 tex multi-filaments of glass tinted green by coating, produced by the company Chavanoz SA of the Porcher group, 163 Boulevard des United States, 69009 Lyon (France).
• the twisted glass filaments represent 22% by weight of the wire.
• the fibers spun around this core contain 50% Kermel R from Rhône Poulenc Textile which is a fire-resistant Polyamideimide polymer and 50% Viscose Flame Retardant, a mass-dyed or unbleached fiber supplied by the Austrian Lenzing Company. About 70% of all the fibers are arranged parallel to the core and about 30% are wound around.
• a textile thread of 42 tex was produced, comprising a glass core formed by a twist of two multi-filaments of 2 ⁇ 5.5 tex tinted orange by coating, produced by the company Chavanoz SA.
• the twist of multi-filaments of glass represents 26% by weight of the wire.
• the fibers around this core comprise 50% of meta-aramid fibers sold under the brand Corex R of the Japanese company Teijin and 50% of Viscose Flame Retardant as in Example 1. About 70% of the fibers are arranged parallel to the soul and about 30% are wrapped around.
• Example 2 We made a 55 tex thread comprising a core a ply of glass multi-filaments as in Example 1. This ply corresponds to 20% by weight of the wire.
• the fibers around the core contain 67% Viscose Flame Retardant, the same fiber as in the previous examples and 33% fire-resistant fibers of a copolyimide sold under the brand P-83 by the Austrian company Lenzing. As before, approximately 70% of these fibers are arranged parallel to the core of the wire and approximately 30% are wound around them.
