The leading silver ion technology for obtaining hygiene, protection and freshness

SILVERPLUS® transfers the element silver into a silver compound which has been applied to microstructured substrates by means of highly innovative coating procedures.

Hygiene and freshnessbased on the reaction mass of titanium dioxide and silver chloride

  • Inhibits the multiplication of odour-causing bacteria
  • Fresh textiles, even if washed at low temperatures, thus, reduction of energy consumption and costs in textile care
  • Resistant to washing and dry cleaning

Fresh textiles even at low washing temperatures


Over their entire life span, significant amounts of energy for washing, tumble drying, ironing or mangling textiles are necessary in the professional or household textile care. The consumption of water and detergent is considerable and exceeds many times the quantities necessary for the textiles‘ production. With an increasing world population we will have reached our limits soon. Integral system optimisation is thus imperative.

SILVERPLUS® ecology: fresh textiles even at low washing temperatures – less energy consumption and better CO2 balance


Due to its micropigmentation SILVERPLUS® anchors to textiles by itself in a resistant to washing and dry cleaning manner without the addition of chemical binder or adhesive systems.

SILVERPLUS® for example deposits in the yarn interstices and is permanently bonded to the substrate due to strong attractive forces. This procedure is comparable with the deposit of soot particles, which, even after repeated wash cycles, cannot be removed by standard detergents.


The use of SILVERPLUS® has been shown to have no negative effects on the environment. The quantities of silver which SILVERPLUS® returns to nature (ppb range) correspond to the average natural silver content of natural soil or rocks.


SILVERPLUS® does not waste important resources, i.e. the antimicrobial active free silver ions; but only uses them if necessary. Free silver ions dispose of extensive antimicrobial effects. Thus even small SILVERPLUS® quantities are sufficient to permanently control odour-causing bacteria in textiles.


Your reliable safety pack for functional final textile finishes


With the OEKO-TEX®-listed SILVERPLUS® products ®RUCO-BAC AGP and ®RUCO-BAC AGL the RUDOLF GROUP ensures that antimicrobially finished textiles will be OEKO-TEX-labelled if they fulfill all other OEKO-TEX® criteria.


With RUCO®-BAC AGP the SILVERPLUS® technology fulfills the stringent ecological and toxicological bluesign® criteria and is, thus, bluesign® approved.


The US-Environmental Protection Agency (EPA) is responsible for protecting the environment and human health. EPA-registered antibacterial ingredients must be used on textiles or other substrates as well as on those textiles or substrates that are intended for the US importation. Any violations will be rigorously punished worldwide by EPA. The SILVERPLUS® products ®RUCO-BAC AGP and ®RUCO-BAC AGL assure you to use the right freshness technology for the importation of these textiles into the US market.

Hohenstein field study

In a field study carried out by Hohenstein researchers, who have been assisted by an external dermatologist, it has been found that the natural skin flora is not affected even if the silver-containing antibacterial clothing is permanently worn.

The clothing only showed the desired fresh effect, thus controlling bacteria that got into the textile and avoiding unpleasant degradation products caused by perspiration. In other words: Safe fresh effects without negative accessory symptoms!

In the meantime, the fresh effect of silver is widely offered to end-users, e.g. in the form of deodorants, to avoid unpleasant odours and to secure freshness.

Laus study

The antibacterial active ingredient (AgCl) of SILVERPLUS® products reacts with the constantly present sulphide (hydrogen sulphide = odour of rotten eggs) to absolutely insoluble silver sulphide (Ag2S) and is thus no longer bio- available. The activity of the important bacteria of biological purging during sewage treatment is not inhibited. This has been confirmed by studies conducted by the independent test institute LAUS-GmbH, Kirrweiler/Germany.
