Freshness redefined for sports gear – HeiQ launches world’s first 100% bio-based, non-antimicrobial, non-silver odor control technology (1/26/18)
The Swiss textile innovator HeiQ launches HeiQ Fresh FFL (Fresh For Long), a 100% bio-based odor
control technology. The product targets the sportswear and intimate segment, with application
especially suitable for seamless garments made of synthetics that are prone to permastink. Visitors
at ISPO Munich can get a first sniff of the technology at HeiQ’s booth at Hall C3 Booth 402 during
The funky founding story keeps the Swiss high-tech company busy in adding more solutions to its
broad odor control product range. Apart from the founding silver product that is today used
worldwide in more than 500 million garments by over 100 major active wear brands, and the
recently launched volatile odor source sequestering technologies HeiQ Fresh NKU and HeiQ Fresh
AGOS, HeiQ continues to redefine freshness for textile by introducing the world’s first bio-based,
non-antimicrobial, non-silver-based textile odor control technology – HeiQ Fresh FFL, which is
based on a biopolymer derived from 100% renewable source. This wash-resistant, biodegradable
textile finishing stops bad smell before it emerges on textile.
HeiQ Fresh FFL is a non-antimicrobial alternative to traditional odor control in textiles. This
sustainable, fully biomass-derived Amino-Sugar-Polymer functions by binding proteins and other
sweat components that can cause odor. The HeiQ Fresh FFL biopolymer supports ready removal of
these sweat components during home laundering. As a non-antimicrobial solution to odor control
the regulatory obligations normally associated with biocides are of no relevance when applying HeiQ
Fresh FFL on garments and other textile products.
“Odor control efficacy is maximized with the correct technology-fiber match, as well as the right
application of the technology in the textile finishing process. While most odor-control textile
finishing target polyester, the application is often limited to padding, which is not utilized for
textiles that seamless garments are made of. HeiQ Fresh FFL can be used on both cellulosic and
synthetic fibers. The flexibility of application of HeiQ Fresh FFL – can be done through either exhaust
or padding – means that brands can apply it freely on different fiber and product design, including
seamless garments.,” says Ralf Mundinger, HeiQ’s Head of Technology Application, “we see this as a
clear advantage for our brand partners in the sportswear and intimate segment.”
Participants in a multi-day wear trial confirmed that the odor control efficacy of HeiQ Fresh FFL is
much better than the best silver antimicrobial textile finishing on the market (control). HeiQ Fresh
FFL was also tested under the newly developed “HeiQ 72-hour Tennis Bag challenge” test protocol,
in which HeiQ Fresh FFL-treated, control and untreated fabrics infused with artificial sweat are
placed into a red Wilson® Federer DNA tennis bag in a climate chamber at 30°C (86°C) and 40°C
(104°F), followed by an olfactometric evaluation. In addition to the many ISO laboratory standard
tests offered, HeiQ wanted to have a “hard hitting” test and suggests olfactometric evaluation,
encouraging brands to “listen to your own nose”, to complement standard laboratory tests in
predicting the physiological experience of the human nose, and give a comprehensive evaluation on
the “real life” odor control efficacy of the technology.
At their booth at ISPO Munich (Hall C3 Booth 402), HeiQ welcomes all visitors to learn more about
the product, not only by asking and listening, but actually using their own noses in sniffing the
differences between HeiQ Fresh FFL and other odor control finishing. HeiQ Fresh FFL is also ready for
any wear trial applications shall anyone wish to prove the odor control performance in the field.
