Abstract

An antimicrobial composition comprising an organic antimicrobial component (K) and at least one metal salt component (M) and also, where appropriate, a solvent (L) and further auxiliary components, which comprises as organic component (K) at least one compound of the general formula (I)

• • where the radicals independently have for example the following meanings:
  • R¹ is a branched or unbranched alkyl radical having 1 to 12 carbon atoms,
  • R² is a branched or unbranched alkyl radical having 1 to 12 carbon atoms,
  • R³ is a branched or unbranched alkyl radical having 1 to 12 carbon atoms,
  • R⁴ is a branched or unbranched alkyl radical having 1 to 18 carbon atoms,
  • R⁵ is a branched or unbranched alkyl radical having 1 to 18 carbon atoms,
  • R⁶ is a branched or unbranched alkyl radical having 8 to 18 carbon atoms;
  • n is an integer from 1 to 6,
  • and which comprises as metal salt component (M) at least one salt of a di- to pentavalent metal, is useful for durable finishing of textiles.

Claims

1. A composition comprising an organic antimicrobial component (K), at least one metal salt component (M), optionally a solvent (L) and, optionally auxiliary components, said organic component (K) comprising at least one compound of the general formula (I)

2. The composition as claimed in claim 1, wherein it comprises as metal salt component (M) a salt of a divalent metal from the group consisting of Mg, Ca, Ba, Zn and/or a salt of a trivalent metal from the group consisting of Al and Fe.

3. The composition as claimed in claim 1, wherein it comprises as organic component (K) of the general formula (I) a dimethyltetradecyl-(3-(trimethoxysilyl)-propyl)ammonium salt or a dimethyloctadecyl-(3-(trimethoxysilyl)propyl)ammonium salt and as metal salt component (M) a salt of a divalent metal from the group consisting of Mg, Ca, Zn, Ba and/or a salt of a trivalent metal from the group consisting of Al and Fe.

4. The composition as claimed in claim 1, wherein it represents an aqueous solution comprising 0.01% to 10% by weight, of the organic component (K) and 0.01% to 10% by weight of the metal salt component (M) and also 0% to 50% by weight of an organic solvent.

5. The composition as claimed in claim 1, wherein it comprises 0.3% to 2.5% by weight of the organic component (K) and 0.2% to 2.0% by weight of the metal salt component (M), 70% to 99.5% by weight of water as solvent (L) and also 0.1% to 30% by weight of auxiliary components.

6. The composition as claimed in claim 1, wherein it comprises as solvent water and also, optionally, an alcohol and optionally an auxiliary component, selected from the group consisting of pH buffers, softeners, hydrophobicizers, oleophobicizers, binders, crosslinkers, flame retardants, textile dyes, sewability improvers, soil repellents and combinations thereof.

7. Textiles, fibers and yarns finished with an antimicrobial and/or antiviral composition as claimed in claim 1.

8. Textiles, fibers and yarns finished with an antimicrobial composition as claimed in claim 1.

9. A process for antimicrobial and/or antiviral finishing of textiles, fibers and yarns, which comprises at least one organic antimicrobial component (K) of the general formula (I) as set forth in claim 1 and at least one metal salt component (M) as set forth in claim 1 and also, where appropriate, solvent (L) and, where appropriate, further auxiliary components being applied to textiles, fibers and yarns at the same time or at different times.

10. A process for finishing textiles, fibers and yarns comprising polyamide and/or polyester as claimed in claim 9.

11. A process for finishing textiles, fibers and yarns by means of padding processes, foam application, spraying processes, coating or exhaust method as claimed in claim 9.
