| abstract |
The invention relates to a method for the production of basalt fibers or glass fibers, wherein in a first process (P1) from a basalt material or glass material pellets (P) and / or frits (F) are produced with a proportion of at least one additive, wherein in a second process (P2) a granulate (G) of the basalt material or glass material and the pellets (P) and/or frits (F) are melted homogeneously in a remelt process to form a melt, with basalt fibers or glass fibers being drawn from the melt, with a antimicrobial and/or antiviral and/or fungicidal additive is used, wherein in the first process (P1) a granulate (G) from the basalt material or glass material is combined with a substrate (K) of the at least one additive and melted to form a first melt (S1). is, from which the pellets (P) and / or frits (F) are made, wherein in the second process (P2) a quantity of granules (G) from the basalt material or glass material with a quantity of the pellets (P) and/or frits (F) produced in the first process (P1) is fed to the remelt process and melted to form a second melt. |
