PLAfter inserting the fibers on the fibers to be screened, the water evaporates, the rubbing should be used in the form of an emulsion, so that it remains plastic and more concentrated. The advantage is that it adheres tightly to the fibers. Introducing the sheath material onto the fiber while the coating of the fibers to be used during their manufacture, that is, until the fibers are still hot. At the same time, this mass increases the strength of the fibers. The invention further envisages the addition of a sterilizing agent, such as mercury chloride, to the coating mass, thanks to which, under certain circumstances, free radicals and bacteria are killed, as well as fibers contaminated with such the coating must not be covered with moldy. In order to increase the active filter surface in the fibers used as filter material, thickeners such as zinc soap may be added to the coating in such a way that lumps or the like are formed on the fibers. protruding parts. Increasing the wicking surface is also achieved by adding gypsum, borax, sodium silicate. In the case of a certain type of glass fibers: the fiber mats are cut into cubes and rolled into rolls or knobs. The presence of more free bases on the fibers is beneficial for cutting and fighting this wool. Of course, the content must however be so small that the abovementioned deleterious effect which the present invention seeks to eliminate cannot occur. For example, if the normal free base content is, for example, about 0.035%, then for the purpose of the last-mentioned it should be increased to approximately 0.045%, and even up to 0.15%. According to the invention, this can be achieved with a little addition of sodium silicate. Depending on the purpose for which the fibers are to be used, the ingredients of the mixtures and emulsions mentioned can be used individually or in any combination. PL

Claims

Patent claims. 1. A method of treating glass fibers, used in particular as a material for thermal insulation or gas filters, characterized by the fact that the fibers are subjected to the action of such chemicals that affect the content of free bases in the surface layer of individual fibers.

2. The method according to claim The method of claim 1, characterized in that the fibers are subjected to the action of substances that neutralize the bases present on the surface of the fibers.

3. The method according to p. 1 and 2 as used in the treatment of fibers provided with an oily or plastic coating, characterized in that a base-active agent is added to the coating compound.

4. Method of treating the fibers according to claim Process according to any one of claims 1 to 3, characterized in that, as a rule, the coating becomes neutral during the treatment preceding the coating of the fibers.

5. The method according to p. 1 to 4, characterized in that an organic acid, for example stearic, abietic or oily acid, is used to neutralize the free base.

6. The method according to p. 1-5, characterized in that an ammonium salt, for example ammonium chloride or sulfate, is used as the neutralizing substance.

7. The method according to p. 5. The method of claim 5, wherein zinc chloride is added to the organic acid-containing coating composition.

8. The method according to p. 1 to 7, characterized in that a wax, for example paraffin wax, is added to the coating composition in order to prevent the coating from dripping from the fibers and to give the coating mass sufficient ductility over a wide temperature range.

9. The method according to p. 1-8, characterized in that the coating or fibers are applied in the form of an oil-in-water emulsion in an amount that provides good lubrication of the fibers, but not too much, so that at normal oil ignition temperature, this amount is not sufficient to generate a fire or to sustain it. - 5 -

10. The method according to p. 1-9, characterized in that materials that reduce the flammability of the mass or suppress the fire are added to the coating.

11. The method according to p. A method according to any one of the preceding claims, characterized in that calcium chloride, ammonium phosphate or other salts with similar properties are used as measures to reduce the risk of fire.

12. The method according to p. The process according to any of the claims 1-10, characterized in that trisylphosphate or other esters of phosphoric acid are used as the means to reduce the fire hazard.

13. The method according to p. The process according to any of the preceding claims, characterized in that a material which kills spores and bacteria, for example mercury chloride, is added to the coating.

14. The method according to p. A process as claimed in any one of the preceding claims, characterized in that thickening materials, e.g. zinc soap, or solids, e.g. gypsum, borax, sodium silicate or similar substances increasing the surface of the fibers, are added to the coating.

15. The method according to p. A process as claimed in any one of claims 1-14, characterized in that sodium silicate or the like is added to the coating in such an amount that the free base content of the fibers increases somewhat to an extent that is not harmful to the fibers and the coating.

16. The method according to p. The process of any one of claims 1-15, characterized in that amines are added to the coating compound. Naamlooze Vennootschap Maatschappij tot Beheer en Exploitatie van Octrooien Deputy: engineer B. Muller, patent attorney DRUK. M ARCT. CZERNIAKOWSKA 225 PL
