Textile finishing for sustainable odor control

Sustainable, silver-free odour control that neutralises smells at the source for long-lasting freshness

HeiQ Fresh™ is a family of odor control textile technologies. The technology helps reduce unwanted smells in textiles during everyday use. The textiles stay fresher for longer by effectively addressing the source of odor. This technology absorbs odor-causing molecules or VOC's (volatile organic compounds), responsible for unwanted smells on textiles to help maintain a fresh textile experience.

 

Key benefits

  • Odor control with durable freshness
  • Addresses body odors, environmental odors, fabric odors, and odor build-up on synthetic fibers (permastink) 
  • Odor control performance is maintained over repeated washes

    HeiQ Fresh™ is a family of advanced silver-free odor control technologies developed to keep textiles fresher for longer in a more sustainable way. Unlike conventional odor management systems that often rely on biocidal action or metallic additives such as silver, HeiQ Fresh™ works by targeting the root cause of unwanted smells: the volatile organic compounds (VOCs) that create odor.

    HeiQ Fresh™ is neither antimicrobial nor antibacterial. It is a silver-free odour control technology that works without biocides. Instead of targeting bacteria, HeiQ Fresh™ neutralises odours by capturing volatile organic compounds (VOCs), the molecules responsible for unpleasant smells, directly on the textile. This approach enables long-lasting freshness while maintaining fabric properties such as breathability, softness, and performance.

    Yes. It uses bio-based or mineral ingredients, is silver-free, and meets OEKO-TEX® ECO PASSPORT and most RSL requirements, making it a more responsible odor control solution.

    HeiQ Fresh™ uses adsorption-based technology to capture and bind odor-causing VOCs from sweat, the environment, and everyday use. The technology physically traps odor molecules, helping prevent their release into the air. It delivers effective odor control without the use of silver, fragrances, or antimicrobial agents.

    Yes. HeiQ Fresh™ is designed to deliver long-lasting performance, even after repeated washing. The technology is engineered to regenerate during laundering, restoring their odor-adsorbing capabilities. This ensures that textiles remain fresh throughout their lifecycle.

    HeiQ Fresh™ performance is evaluated using standardised odour control test methods that measure its ability to reduce or neutralise odour-causing compounds. Key methods include:

    • Odour emission tests (ISO 17299-2 modified (propionic acid))*: measure reduction in odour intensity
    • Deodorant efficacy tests (ISO 17299-2 (ammonia))*: assess neutralisation of specific odour molecules
    • HeiQ ASP Colouration test*: demonstrate interaction with odour-causing compounds
       

    *Quality Assurance (QA/Quality Control (QC) test method (at cost if used for QC purpose)

    Additional durability and wash-resistance tests can be applied depending on the textile application. These methods ensure proven, measurable, and long-lasting odour control performance.

    Yes. Different textile finishes can be combined on the same fabric to deliver multiple effects at once. The key is formulation and process control. Finishes must be compatible and engineered to work side‑by‑side during application and remain stable during use and washing. Well‑designed combinations extend fabric functionality without changing how the textile feels or behaves in daily wear. For example, a garment can manage moisture while also reducing odour build‑up.
