he Netherlands-based polyester fiber manufacturer Advansa has brought its Thermo°Cool™
hybrid thermoregulating, moisture-management technology to North American apparel market. Launched
earlier this year in Europe, Thermo°Cool made its US debut at the 2008 Summer Outdoor Retailer Show
in Salt Lake City.
According to Advansa, the techology involves the intimate blending of hollow-core fibers –
to provide a thermobuffering function to insulate the wearer from temperature changes and protect
against chills following periods of high activity – and multi-channeled fibers – to provide
moisture management and evaporative cooling as well as help with ultraviolet resistance – all
without the use of finishes. The hybrid fiber, offered in both staple and filament form, is the
first and only combination of the two fiber types available on the market today. In testing,
Thermo°Cool fabrics have been shown to provide 48-percent better moisture management and 53-percent
better evaporative cooling than other performance fabrics.
Club of Comfort® is using Thermo°Cool™ in its line of casualwear.
First introduced in polyester, the technology also is offered as Thermo°Cool ECO using
bio-based DuPont™ Sorona® polytrimethylene terephthalate (PTT) polymer. PTT chemically is similar
to polyester and offers that polymer’s printable and dyefast attributes, but it behaves more like
nylon in terms of its fluidity, softness and drape. Additional benefits of the ECO version include
its dyability at lower temperatures than for polyester and its quick-drying properties, both of
which reduce energy usage. Because it is highly durable, it is not biodegradable, but it is
recyclable, and it has qualified to carry the Oeko-Tex® label.
In addition to its standard polyester and renewable Sorona PTT variants, Thermo°Cool also is
offered in a blend with Tencel® lyocell from Austria-based cellulosic fiber manufacturer Lenzing
AG. According to Tricia Carey, merchandising manager, Lenzing Fibers Inc., the addition of Tencel –
which is derived from eucalyptus pulp in a closed-loop process – brings enhanced moisture
management to the blend, as well as the soft hand and other aesthetics associated with a natural
fiber. Tencel’s own capillary action and moisture absorption allow moisture to spread over the
fabric and evaporate quickly from its outer surface, while Thermo°Cool’s multi-channel component
quickly wicks moisture from the body. Tencel also contributes antistatic properties to the blend.
Thermo°Cool fibers and yarns are produced at Advansa plants in Germany and Turkey. Fabrics,
manufactured by licensed mills, are certified for performance by the company.
Denine Woodrow, president, DP Woodrow & Co. LLC, which represents Advansa in North
America, said Advansa is targeting the Thermo°Cool product line to sports-, athletic- and
performancewear; hosiery and socks; and casualwear markets. European brands that have adopted the
program include Alpine Pro, Czech Republic; Club of Comfort®, Germany; and Spain-based Grifone® and
Lurbel. US brands are currently sampling fabrics.
