• the fabrics according to the invention are particularly suitable for use as horizontally attached ceiling coverings in sprinkler systems or as vertical wall coverings for sprinkler systems.
• Glass threads in the context of the invention are to be understood as glass threads that consist of a plurality of individual glass filaments exist. These threads can be one Have protective twist. Instead of a thread made up of multifilaments a monofilament glass thread can also be used.
• Another option for building the fabric is to use Glass fiber yarns, the glass fibers being in the form of lumber. Even such Glass staple yarns are known per se to the person skilled in the art and their production does not pose any problems.
• polyester threads or polyester fiber yarns Another possibility within the scope of the invention is to build up a fabric the use of polyester threads or polyester fiber yarns.
• polyester threads threads that consist of a variety of Filaments exist, so-called multifilament threads or multifilament yarns or usual polyester monofilaments.
• Yarns are closed under polyester fiber yarns understand that are made of polyester staple fibers.
• the raw fabric as such is made with a plastic is coated.
• plastic in solid form, e.g. B. in the form of powder
• the fabric is made of Builds threads or yarns in which the fibers or threads already with the Plastic material are encased.
• the plastic can be treated by treating the glass fibers or Glass filaments with a plastic melt or a plastic dispersion or Plastic solution are applied.
• the plastic preferred for fiber production using a multi-component nozzle applied through which the polyester as the core component and the plastic as Sheath component is extruded.
• the flame retardant additives are preferred together with the plastic applied.
• the flame retardant or additives are already dispersed or dissolved in the plastic and either with Coating is applied to the fabric or in the manufacture of the Bicomponent fiber or filament is used as a sheath component that which already contains additives.
• the production of the sprinkler system covering using Polyester monofilaments with a polyester core can e.g. B. in the following way happen: First, core sheath filaments are made in a manner known per se is produced, in particular a melt-spinnable core material Polymer used, made entirely or partially of polyester in particular There is polyethylene terephthalate. Preferred is the jacket component Polyvinyl chloride used.
• the polyvinyl chloride contains one or more flame retardant additives that are as homogeneous as possible in the polyvinyl chloride are distributed. Common flame retardant additives are suitable as additives.
• the fabric is preferred after the completion of a thermal Treated so that the filaments pass through at their crossing points Melting or melting of the jacket can be connected to each other and fixed. This gives the fabric good surface stability.
• the fabric is used according to the area of application Sprinkler system assembled. To do this, u. a. the High frequency welding process or the hot wedge welding process. Also the fabrics can be made up accordingly by sewing.
• the density of the weft and warp threads is adjusted so that the Area coverage is 15 to 80%. Under area coverage in The ratio of covered area to area is to be understood within the scope of the invention Total area of the fabric.
• the titer of the monofilaments used can be in relatively wide ranges can be varied, for example between 1,000 and 2,000 dtex.
• a very beneficial one Composition is, core with a titer of 550 dtex and coat with a Titer of 850 dtex.
• the area coverage can be influenced on the one hand by the binding technique become, d. H. by the number of warp and / or weft threads per cm or by the titer of the yarn from core / sheath filaments.
• the fabrics can be used directly printed, in particular digitally printed, d. H. without a finishing such as B. by painting.

• the coverings are horizontal below the sprinkler system appropriate. You can directly below the sprinkler system on the ceiling be attached. But it is also possible to clamp them in frames and in Form of frame to attach to the ceiling.
• the fabrics have a calm and closed picture and do not leave recognize that it is actually only used to cover the sprinkler systems become. They therefore offer a textile or wallpaper-like image. You can use the customary solvent-based colors printed according to digital printing technology and thus offer the possibility of a very attractive ceiling to give aesthetic character.
• the coverings can also be used vertically in sprinkler systems, which are integrated in the walls of rooms.
• the coverings offer those created during the fire Heat radiation is not an obstacle, so that the sprinkler system when a Fire can function immediately. Because of the chosen Coverage is provided by the coverings when the water is expelled through the Sprinkler system also has no serious resistance, so the water at Sprinkler system operation immediately sprayed onto the fire site unhindered can be. This applies to both horizontal and vertical installation.
• the sprinkler system coverings according to the invention can therefore also advantageously be used as ceiling covering material for covering the exhibition stand. Areas of up to 30 m 2, for example, can be freely spanned. A disturbing sagging can be avoided by appropriately strong tensioning.
