PROLEN®SILTEX is a special  polypropylene yarn treated with a permanent antibacterial additive, based on silver phosphate glass.
PROLEN®SILTEX is effective against the growth of bacteria and unpleasant smells for hygienic freshness. It is harmless for humans and the environment.

The antibacterial effect of silver has been known already for many centuries. Silver ions inhibit the growth of bacteria, reduce unpleasant smells, keep a biological balance of your skin and set hygienic freshness to the product during sports and leisure activities. Due to the fact that the bacteriostatic agent is applied to the core of the yarn and not to its surface, it doesn`t migrate from the fabric and permanently remains in it even after multiple washing.

PROLEN®SILTEX has been created for underwear, sports garments, workwear, socks, filling material for shoes, bedclothes, lining and upholstery to protect in environments which require high hygienic standards.

Certificates and Test Reports

Antibacterial properties have been approved by the VUTCH – CHEMITEX certificate according to the standard AATCC TM 100: 2012 (Klebsiella pneumoniae, Staphylococcus aureus) and by the VUTCH – CHEMITEX test report according to the standard ASTM E2149-13a (Escherichia coli).

PROLEN®SILTEX fulfills the requirements of Oeko-tex® Standard 100 – class 1- baby articles. The human-ecological properties of PROLEN®SILTEX are Bluesign® APPROVED.



Trevira Bioactive forms the basis for fabrics with permanently bioactive properties. These properties prevent bacteria multiplying in or on the fibre and so improve hygiene.

Trevira Bioactive properties
The familiar functions of Trevira fabrics, such as their low pill, elastic, hard-wearing, breathable or heat-regulating properties, remain unchanged. But now they’re joined by a welcome new addition to the team  – Trevira Bioactive’s antimicrobial effect. The antimicrobial function is created through the use of bioactive Trevira fibres. Trevira Bioactive textiles made with these fibres contain built-in protection against micro-organisms. Trevira Bioactive fibres protect textiles through minimising the growth of bacteria in and on the fabric.

Effects that last forever
Unlike products that are given post-production treatments or finished with substances likely to migrate into the environment, Trevira Bioactive has an antimicrobial agent which is firmly integrated in the fibre polymer. This additive has a permanent antimicrobial effect.

Tested for certainty
Comprehensive tests carried out by independent external laboratories have proven that bioactive Trevira fibres have an antimicrobial effect, demonstrating that the bioactive component prevents the exponential growth of bacteria populations on the fibre surface. In an extensive long-term study, the Hohenstein Institute has also shown that Trevira Bioactive textiles are kind to the skin. The antimicrobial effect is restricted to the fibre surface, as substantiated by tests carried out for skin compatibility and cytotoxicity, where there was no evidence of skin cell damage. The skin flora and other physiological skin indicators did not show any significant changes through contact with Trevira Bioactive. And as a textile, Trevira Bioactive naturally also offers all the advantages of tried and tested Trevira fibres.
