BACKGROUND Patent Application MX 91000150, and Patents JP 9059857, JP 2002052307, JP 2001279073 JP2003183509, JP2004300601 and US 6, 498.227 B1, which relate to processes, additives or coatings for retarding fire in the none of the cases is spoken of the constitution of the fabric, some of the cases use both carbon black and red phosphorus but never as part of the product. Likewise JP8074141 patent, is a product retardarte the fire, and uses different compounds to the fibers of our invention, and our invention is not retardant to fire but fireproof.

There are previous documents that although they describe fibers such as Application 2203006, PA a / 1996/006745, Publication No. 166068 and that of Patent JP 2003268651 are of different origin from our invention since they have the disadvantage of not having a adequate flexibility and rough appearance to the touch.

The patent application WO2004 / 031465 A1, WO 0242534, US 6,812,171 B2 and JP2003239163 in these documents specifies that the nonwoven is composed of two layers, an acrylic fiber with flame resistance with its characteristics and a non-woven fabric of Carbon fibers with their characteristics saying that it is produced by applying a carbonization treatment. Ours is the process of mixing the fibers and not the carbonization of these. The patent application WO 99/37852 the MX9606745 and the JP Patent 2004270095describes a treatment to achieve the flame retardancy, however unlike what is proposed in the present invention is not a treatment on the fibers but the combination of these for the obtaining of a final product, and that is fireproof. The patent application EP 1 466 940 A1 and the patent application US 2004/0241440 A1 describe a composite of carbon napo-fibers and dispersion elastomers, a composition resulting from the different constitution of the present invention. The application JP2002129456 deals with a process for the manufacture of a cushion with retardarte to the flame that does not lose resilience over time and is achieved by the placement of carbon fibers in different directions. Ours is the mixture of two types of fibers passed through a mechanical process for the formation of a non-woven fireproof fabric.

Although some of these documents have a fiber that has adequate characteristics of flexibility, these are obtained by a process that differs, in that the process of the present invention consists of mixing the 2 fibers by specified weights, varying the percentages of the 2 fibers. fibers according to the final application with a range of 50/50 to 90/10 with the first percentage being that of the OPF fiber and the second PES. Mixed through a system of rollers with tines called loaders / weighers that homogenize the dosed amount of each component. From there it passes to an air-driven system that mixes the two components again to achieve a greater homogeneity called fine opener, leaving a bicolor mixture. From there it passes to a carding system which is known as a high production card prepared to handle fine fibers that forms a gray nappa through the exact mixture of the 2 fibers. This nappa passes through a pre-punched mechanical reinforcement system, punched on both sides that interweaves the fibers three-dimensionally giving it longitudinal and transversal resistance, resulting in a non-woven "fabric" with a predetermined weight per square meter. The edges are rolled and cut to the desired width, obtaining rolls of a specific length and an exact width. It is passed to a calendering system with pressure and temperature to give a homogeneous and calibrated thickness to the whole width of the fabric, this being the product that will be cut in the necessary dimensions. And on the other hand the product of the aforementioned document has a totally different process.

DETAILED DESCRIPTION OF THE INVENTION Mix the 2 fibers by specified weights, varying the percentages of the 2 fibers according to the final application with a range of 50/50 to 90/10 with the first percentage being that of the OPF fiber and the second PES . Mixed through a system of rollers with spikes called loaders / weighers that homogenize the dosed amount of each component. From there it passes to an air driven system that mixes the two components again to achieve a greater homogeneity known as a fine opener, leaving a two-color mixture. From there it passes to a carding system called high production card prepared to handle fine fibers that forms a gray colored layer by the exact mixture of the 2 fibers. This nappa goes through a mechanical reinforcement system called pre-punching, punched on both sides that interlaces the fibers three-dimensionally, giving it longitudinal and transversal resistance, resulting in a non-woven "fabric" with a predetermined weight per square meter. The edges are rolled and cut to the desired width, obtaining rolls of a specific length and an exact width. It is passed to a calendering system with pressure and temperature to give a homogeneous and calibrated thickness to the whole width of the fabric, this being the product that will be cut in the necessary dimensions. EXAMPLE The blanket can be exposed to direct fire at temperatures greater than 1000 ° C for a period of 15 seconds without burning or producing heat.

PREFERRED MODE OF THE INVENTION The preferred embodiments of the fireproof blanket, is in a presentation in such a way that it can cover any type of object to avoid burning. At the same time it can be used to extinguish small fires just by covering the fire.

On the other hand it can be used by people who are in a building that is burning, the only thing you have to do is cover yourself with it and transfer the fire without the minimum risk of burning.

On the other hand it can be used for the construction of clothing or blankets against fires for those people who are at risk of fires as in the case of car pilots or test pilots. Also for the construction of furniture, floor coverings, walls, ceilings to prevent fires. For cushioning of furniture, bedding, mattresses, seats and backs of cars, buses, trains and airplanes. Cover for furniture to prevent fire. It can be used as a protective fire blanket for the protection of any item as it can be produced in any length and thickness. Support for wallpaper and fire curtains. Under carpet against fire. Thermal cover protector against fire. Blankets of protection that serve to transfer fires in fires in Hotels, Prisons, Trains, Aircraft, Spacecraft, Trains, Ships. Clothing for aircraft pilots, train drivers. Clothing or cover for people who work with the fire such as steel factories, application of electric welding, grinding, cutting with torches or as protection to stop or contain sparks, hot slices, hinder flashes.
