Definitions
- the present invention relates to an insulation material thermal.
- a material constituting a firebreak which is in the form of a sheet made from a wire made of two synthetic materials, aramid and pre-oxidized, the wires being cracked, mixed, spun and knitted.
- the sheet thus obtained has holes relatively large formed by meshes and which, thanks to the down formed by the cracking operation, traps a certain amount of air which constitutes insulation natural thermal slowing the conduction of heat.
- This down also forms an optical filter whose lengths cut-off waves correspond to those of radiation thermal emission spectrum of the flame of a fire.
- This fabric is light, easy to use and constitutes a fire barrier reducing radiation of a flame front.
- One of the aims of the present invention is, starting from a thread used for fabric making flame arrester, to make a fabric capable of constituting a coating for the thermal protection of organs or of devices.
- the invention relates to a manufacturing process a thermal insulation material in which we use stubborn yarn from a synthetic aramid yarn and a preoxidized synthetic yarn, these yarns being cracked to get fibers that are mixed and spun, said process being characterized in that, from several of these threads, a wick, said wick being knitted to obtain said material.
- the invention also relates to the material obtained according to the above method and which is of the type produced from a synthetic aramid yarn and a synthetic yarn preoxidized, these threads being cracked and the fibers thus obtained mixed and spun, said material being characterized in that it consists of a wick made from several of these threads, the wick being knitted.
- the wick is formed of at least four threads knitted on a lace-making machine.
- the wick has a size included between N.M. 2.8 and N.M. 6.
- the wick is knitted on a loom garnished with large needles.
- Insulation material is made of fibers made from a known synthetic aramid yarn commercially under the name of "KEVLAR” and a thread pre-oxidized synthetic known commercially as of "SIGRAFIL 0". PANOX-PREOX.
- These threads are made in a continuous form, the synthetic aramid yarn being light and having qualities of mechanical resistance, while the wire synthetic pre-oxidized is thermally stabilized, non-flammable and does not melt when heated.
- the wires are subjected to a cracking operation to stretch them until they break to get fibers having lengths between 60 mm and 200 mm.
- the fibers are mixed in the proportion 70% of fibers of the preoxidized synthetic yarn and 30% fibers of synthetic aramid yarn.
- This wire thus obtained has, on its surface, fibrils which constitute a down and form a network reflective elements.
- the wick thus obtained has a size of N.M. 2.8 (i.e. 2800 m for a kilo) to 6.
- This wick has curls that enclose air trapped between the fibrils.
- the lock obtained is knitted on a loom with large needles (gauge 2 to 6) and you get thus a knitted fabric which has a certain thickness and a certain volume of air which lends itself perfectly thermal protection of parts or devices for example liquefied gas tanks, electric batteries, batteries etc ...
