Definitions
- the invention relates to an asbestos-free twine for attaching incandescent lamps to burners incandescent lamps, the incandescent bodies of which are exposed after the attachment of a flame, the twine consisting of a refractory material and one
- twine For the mechanical durability of a filament on the burner incandescenter lamps, in addition to the number of sewing stitches with which the twine is sewn into the filament fabric, sewing through both fabric layers, if necessary, if the end of the fabric tube is turned over, especially the nature of the Twine of importance.
- the selection of the twine is subject to various criteria. It must be resistant to high temperatures, retain textile properties even at high temperatures and neither become hard nor brittle, i.e. a steel thread cannot be used and the knot must hold up well.
- asbestos yarn was the only binding thread used in incandescent bodies. This yarn was resistant to high temperatures and easy to knot. However, it has the disadvantageous property that it is harmful to health and has therefore been banned in many countries. The disadvantageous properties of asbestos, in particular the restricted use due to the ban, have caused the search and use of new binding yarns.
- binding yarns based on glass fiber, ceramics, organic materials are known.
- disadvantageous properties These yarns have such a smooth and frictionless surface that they are difficult to knot or the knot is easy to open. (A knot only holds due to friction). With low text number, low tear strength, poor processability, e.g. when sewing, cutting, etc.
- Common binding yarns from which the invention is based consist of a glass fiber or ceramic core or silica core of approximately 0.2 mm in diameter covered with cotton from staple fibers in accordance with international patent application PCT / GB92 / 00432, so that a total diameter of approximately 0.5 mm results.
- the object of the invention is therefore to provide an easy-to-use yarn which is easy to knot and which also increases the service life and durability of a mantle sock when exposed to impacts and blows.
- an asbestos-free twine for attaching incandescent lamps to burners, incandescent lamps, the incandescent bodies of which are exposed after the attachment of a flame, the twine consisting of a refractory material and one
- twine is understood to mean any flexible, one-dimensional body, thread, yarn or ribbon. In the case of tapes, their thickness takes the place of the diameter.
- the yarn consists of a refractory material that is knitted, interwoven or spun with itself. This makes it possible to dispense with staple fibers, which means that no complex DREF machines are required.
- twine is understood to mean any flexible, one-dimensional body, thread, yarn or ribbon.
- Texturing is understood to mean various processes for increasing the volume of the smooth, structureless filaments. Become smooth yarns For example, constantly crimped, so-called crimped yarn, crimped yarn, bulk yarn, stretch yarn is produced, the stretchability and elasticity of which is increased due to its appearance similar to spun fibers
- a yarn has proven to be particularly suitable, in particular a silicate yarn which is textured by means of a jet blowing process.
- the yarn has an etched surface.
- the type of yarn is not restricted, all high-temperature yarns with a smooth surface can be used without exception, such as yarns made of glass fibers, carbon fibers or mineral fibers or any mixtures thereof.
- the etching can be done, for example, with hydrofluoric acid.
- Significant diameter shrinkage advantageously does not take place, so that the incandescent body has an increased service life.
- the high temperature yarn e.g. Silica yarn, among others, is etched in hydrofluoric acid, then washed and dried.
- the yarn is covered by a layer of combustible material, preferably wrapped, knitted, braided or wound around by continuous filaments or continuous yarns.
- Such a layer can be produced particularly inexpensively if the layer consists of a plastic, preferably a polymer.
- the high-temperature yarn is mixed with an artificial polymer or a natural polymer and the smooth surface of the original yarn is coated with it.
- the high-temperature yarn is mixed with monomers or prepolymers, which are then polymerized so that the effects, inter alia, can be achieved.
- Examples of such polymers are polyacrylates, polymethacrylates, casein, polyacrylonitriles, latex but also polymers are referred to as high temperature polymers due to their properties.
- the refined yarns can be produced with simple aids and can be produced using various methods. This can be done by soaking, mechanically moving or spraying the yarn and then drying it, etc.
- the chemical finishing changes the text number of the raw yarn only slightly, so that the disadvantages of the yarn according to the prior art do not occur.
- the incandescent body produced with the new yarn described here has a higher mechanical durability on the burner than the incandescent body produced with the known yarn, since even after the
- the filament is just as firmly connected to the burner as it was before it burned.
- Textile auxiliaries such as plasticizers, surface-active substances, etc. can also be added to the chemical bond.
- the specialty game produced in this way can be subjected to a finishing agent.
- the attached chemical compound either burns without residue or the amount of residue is so small that it does not affect the performance of the filament.
- the possibility of dyeing the yarn is of great importance. This can be done by adding a dye to the solution or dispersion in which the chemical compound is located, whereas glass fiber and other similar fibers are difficult to dye.
- the yarn consists of several fiber strands, preferably 2 to 3, preferably twisted, fiber strands, which in particular have a length-related mass of 170 Tex per fiber strand, it can be soaked particularly easily with such plastics.
- the yarn treated in this way if it consists of a number of filaments and possibly also staple fibers, becomes a compact unit due to the chemical finishing and behaves like a thread, as a result of which the Processability (sewability, cutability, machine processing, etc.) is facilitated and improved.
- the yarn can have a knitted, knitted or spun outer surface. Due to the surface structure created by these processes, the friction is reduced to such an extent that the yarn is easy to knot.
- the yarn consists of a mixture of refractory fibers and combustible fibers, the proportion of refractory fibers preferably being greater than or equal to 60 percent by volume, this already leads to the desired increase in the service life, even if a part burns off.
- the diameter shrinkage is additionally reduced.
- the invention relates to the intended use of twine on a filament, which consists of a fabric tube with at least one open end, wherein a fireproof fastening material is provided for fastening the hose ends to a burner or to a molded part for a burner of an incandescent lamp.
- Such incandescent bodies consist of a circular knitted carrier material, generally viscose is used, which is mixed with metal salts.
- the incandescent body is usually attached with a twine either directly to a burner or first to a prefabricated molded part for the burner (the molded part is placed on the burner by the end user with the attached incandescent body) and then burned down and lit in the gas flame.
- the carrier material burns off completely and only the oxide skeleton of the metal salts remains. Low mechanical stress is enough to destroy it. If this oxide framework is now exposed to shocks or vibrations, e.g. when the lamp is transported or handled carelessly, the incandescent body is generally destroyed at its weakest point, namely on the burner.
- One consists of reinforcing the tissue at the point of contact with the burner.
- the tissue in the burner area is turned inside out and chemically reinforced in this area and is therefore duplicated.
- the tissue and the oxide scaffold that remains after burning off now consists of 2 layers that are chemically reinforced. This double-layer oxide structure increases the time that the incandescent body remains intact on the burner when it is subjected to knocks and blows.
- Another way is to select the twine with which the incandescent body is bound to the burner.
- a thread is sewn into the fabric.
- Different burners require different binding of the twine.
- a yarn is inserted into the fastening opening or into the two during production
- the incandescent body is drawn together and pre-knotted during the production process, the diameter of the opening remaining in this way being specified to the nearest tenth of a millimeter.
- the fastening material also has an influence on the durability of the filament.
- the twine is the most common method of fastening the filament.
- Incandescent lamp is damaged.
- the vibration time is the measure for checking the mechanical resistance to impacts and impacts.
- the incandescent bodies manufactured according to the present invention surprisingly have an extended durability and service life by more than three times.
- the incandescent body in the sense of the invention wears out in a completely different way than the conventional incandescent body.
- the conventional incandescent body is destroyed by successively separating the oxide structure from the twine until it is no longer held by the twine and falls off the burner. If the incandescent body produced in the sense of the invention is exposed to shocks, impacts and vibrations, the oxide structure no longer separates from the binding yarn and is therefore held on the burner for a considerably longer time.
- This incandescent body is below the Fastening and destroyed in the incandescent body itself, so that the durability of this incandescent body depends only on the nature of the oxide structure from which the incandescent body is made and on the shape of the burner.
- Fastening material thus serves as a protective medium when the incandescent body is exposed to shocks, impacts and vibrations, which prevents the oxide framework from separating from the fastening material.
- This fastening material can be incorporated as a thread, for example as follows:
- loops can be several that are worked in continuously, or individual and separate ones that are attached to different places along the opening, and each of which can also be knotted.
- d- it is attached to the inside of the filament in the area of the burner (e.g. by gluing or tacking).
- the twine is looped through the fabric tube over the circumference of the fabric tube.
- the at least one loop or the loops do not necessarily have to be already in the unsecured state, but can only form during attachment to the burner.
- the loops do not have to be closed either, but can also be present, for example, as meanders.
- a further increase in durability can be achieved if the twine is looped around the end of the fabric tube. As a result, the fabric end is simultaneously reinforced by the loops formed. After the sewing thread has been sewn around the incandescent body according to the usual method, it can also be worked in again around or along the opening of the incandescent body and thus becomes the protective medium in the second circulation.
- the incandescent bodies need only be changed slightly in order to achieve the advantages according to the invention if the twine is arranged so as to be penetrating at a distance from the end of the fabric tube, it being attached to the fabric tube in such a way that it forms loops when tightened.
- additional spacers or threads can advantageously be dispensed with.
- the twine itself acts through the loops that form itself the spacer.
- the binding twine itself after it has been sewn in around the incandescent body according to the usual method, is worked in again around or along the opening of the incandescent body and thereby in the second circulation to the protective medium.
- the twine is not sewn around in the glow body using the usual method.
- the twine is sewn in a loop around the opening of the incandescent body, so that in the area of the incandescent body facing the burner, interposing the yarn. It is both a binding medium and a protective medium.

- Figure 16 a plan view of the yarn according to a further alternative embodiment.
- FIGS. 1 and 2 denotes the incandescent body, which is first knitted endlessly and has an open end 2 after a separating cut. At a preselected distance from the end 2, a textured twine 3 is drawn through the circumference of the incandescent body in such a way that it alternates between inside and outside. Pearl-like refractory bodies 4 are drawn onto the inner sections of the textured binding yarn 3. For this purpose, these bodies have corresponding holes through which the textured twine can be passed. This arrangement is preferred.
- FIGS. 3 and 4 show an alternative embodiment in which a thread 6 acts as a protective medium. As in the example described above, the textured twine is passed alternately through the incandescent body.
- the thread 6 is guided in the inner regions 7 of the textured yarn 3 around it in the form of a loop 8 and thus slidably attached to the twine 3.
- the ends of the thread 6 are fixed to the incandescent body by means of a knot 10.
- the thread 6 forms loops 9.
- the formation of the loops 9 can be reproducibly influenced by the guidance and / or type of loops 8.
- FIGS. 5 and 6 show a further exemplary embodiment in which the thread 6, which serves as a protective medium, is passed alternately through the incandescent body 1 around its upper end 2.
- the thread 6, which serves as a protective medium is passed alternately through the incandescent body 1 around its upper end 2.
- loops 9 are formed which envelop the end 2 of the incandescent body 1 in the manner of a buttonhole stitch.
- This species shows a particularly long lifespan.
- FIGS. 7 and 8 represent a variant of the embodiment according to FIGS. 5 and 6.
- the twine is not guided through the incandescent body 1 but through the upper ends of the loops 9 of the thread 6, so that the glow body 1 is now attached to a burner indirectly via the thread 6.
- incandescent body is turned inside out so that it is double-layered in the area between the end 2 and the cutting edge 11.
- This area can also be chemically reinforced and / or colored.
- the inverted area can also be knitted from refractory material and thus represent a fabric 13 according to the invention, which takes over the protective function.
- FIG. 9 shows an embodiment in which the twine takes on both the protective function and the binding and holding function.
- the twine 3 is placed twice around the circumference of the incandescent body and passed through it several times alternately. On the route of one revolution, it is firmly connected to the incandescent body at several points 12, while it displaceably penetrates the incandescent body on the route of the second revolution. When tightening the twine, it therefore forms 12 loops along the route with the fastening points.
- the incandescent body in the area of the burner according to the above Methods processed with a textured binding yarn have a much higher durability when exposed to knocks, bumps and vibrations. Without significant loss of durability, the incandescent body produced in the sense of the invention can be used as an alternative to the traditional processing method in the area of the burner, i.e. hitting the
- Incandescent body so that the incandescent fabric lies twice on the burner and sewing the twine through both fabric layers, as follows:
- Glow body fabric layer of choice (depending on the type of burner) sewn. This makes sewing the binding medium quicker and easier.
- the glow body fabric is no longer turned inside out, and the binding medium is only sewn through a glow body fabric layer.
- the binding medium can be sewn more easily and quickly.
- c- The introduction of the binding medium can be carried out more easily, quickly and with perfect regularity by the binding medium on the knitting machine in the knitting process of the carrier material (usually viscose) from which the incandescent body is produced and introduced at the point on the knitting direction Burner is attached.
- This knitted-in binding medium is subjected to the further processing of the knitted goods without damage to the finished incandescent body.
- the binding medium knitted in this way can be handled in the same way as the binding thread sewn in the traditional way with more or less stitches in order to attach the incandescent bodies to the burner.
- FIG. 10 denotes the binding yarn according to the invention, which consists of a number of refractory fibers 14 twisted together, the surface of which has been roughened by an etching process.
- Such a yarn avoids shrinking in diameter after burning and is nevertheless easy to knot.
- Fibers made of a combustible material 15 can also be added if their proportion and diameter are selected such that after burning the loss of diameter remains below the value according to the invention, as is shown, for example, as a cross section in FIG.
- the fibers 14 and, if desired, combustible fibers 15 are shown embedded or encased in a matrix 16 made of a polymer as a cross section and in FIG. 12 as a schematic view.
- This envelope only slightly increases the diameter. There is hardly a measurable loss of diameter when it burns off.
- FIG. 14 shows a schematic axial section and FIG. 15 shows the cross section according to a further alternative embodiment in which a yarn made of refractory fibers 14 from a sheath 17 combustible fibers 15 is surrounded.
- this sleeve 17 is designed thinner than in the prior art.
- the fibers 15 are spun, knitted, braided or knitted around the core, that is to say around the inner refractory fibers 14.
- the refractory fibers 14 can also be spun, knitted, braided or knitted directly with one another to form a yarn, so that the structure resulting from the process provides a sufficiently rough surface 18 is created, which makes the yarn easily knotted and shows no loss of diameter when it burns. Flammable fibers can then be dispensed with entirely.
