The invention relates to an asbestos-free binding yarn for fastening incandescent bodies to burners of incandescent lamps whose incandescent bodies after the fastening are exposed to a flame, wherein the binding yarn consists of a fireproof material, preferably silica yarn. For improving the knotting ability of the yarn it is envisaged that the binding yarn after exposure in the flame has a diameter changed of less that 50% of its original diameter. The subject-matter of the invention is also the use of the binding yarn on an incandescent body for increasing its retention and durability. |
