"Textile fabrics for protection against thermal radiation" 5

The innovation relates to a textile fabric as protection against thermal radiation according to the generic term of the main claim.

Protective clothing with a reflective protective layer is

This is particularly necessary in the production of metal or glass, as the workers in the blast furnaces or melting tanks are exposed to strong heat radiation. To protect against this heat radiation, textile fabrics are used as protective clothing that reflect the heat radiation as well as possible.

Such reflective protective clothing is already widely used as protective suits, aprons, jackets, trousers, gloves and shoes or overshoes, and aluminum color pigments or silver and gold color pigments are used as the reflective protective layer.

The term "textile fabric" refers to textile fabrics made essentially from fibres, including all types of fibre fleece, fibre mats, insulation materials, etc., as well as products made from them or equipped with them.

testimonies understood.

In technology, intumescent particles are materials that expand and swell when exposed to heat. Due to their intumescent behavior,

Intumescences are used particularly as flame retardants in technology.

In the previously known protective clothing for thermal protection, for example for foundry workers, such clothing is found in

Colour-coated protective clothing allows sufficient radiation and reflection of the heat that occurs. However, foundry workers face the problem that small metal particles are repeatedly thrown out, for example from the pouring trough, and can damage the protective clothing, penetrating the film coated with reflective materials and reaching the textile underlayer of this protective clothing. This can then lead to localised burns for the worker wearing the protective clothing.

The innovation is based on the task of achieving additional protection in protective clothing for this special application.

This problem underlying the innovation is solved by the teaching of the main claim.

Advantageous embodiments are explained in the subclaims.

In other words, it is proposed that intumescent particles be incorporated into the upper part of the textile fabric, which is equipped with a reflective layer to protect against heat radiation, which, for example,

made of expanded graphite. These particles have the task and effect of expanding and swelling when they are hit by fine metal or glass splashes and, on the one hand, lower the temperature of the splash due to the energy consumption during the expansion, and on the other hand,

Inflating carries the metal splashes or glass splashes away from the supporting layer of the textile surface, so that the previously feared penetration of the textile surface by the glass or metal splashes can no longer occur.

The desired effect is fully achieved through the dual effect of energy absorption on the one hand and pushing the impacting hot particles away from the textile base layer of the protective clothing on the other. 5

Preferably, the intumescent particles are incorporated into the adhesive layer with which the reflective coated film is attached to the insulating layer, which consists of a flame-retardant or non-flammable material. 10

Instead of the expanded graphite mentioned above, ammonium polyphosphates and/or dicyandiamide can also be used.

An example of the innovation is explained below using the drawing.

The drawing shows a section through a textile fabric in an exaggerated scale.

In the drawing, 1 denotes a textile fabric,

which consists of an insulating layer 2 made of state-of-the-art, flame-retardant or non-flammable material. A film 3 is applied to this insulating layer 2 by means of an adhesive layer 5, which is coated on its outside with color pigments 4, for example gold-colored color pigments, which

the reflection layer. According to the invention, intumescent particles 6, for example expanded graphite, are embedded in the adhesive layer 5 that fixes the film 3 to the insulating layer 2. If the color pigment layer 4 and the film 3 are penetrated by hot, glowing metal or glass splashes,

These splashes reach the expanded graphite layer, which expands due to the heat development, thereby on the one hand leading to energy consumption, on the other hand pushing the impacting particle away from the insulating layer 2, outwards, so that the insulating layer 2 is not damaged by this particle through

can be penetrated.
