ENHANCED PERFORMANCE
Formed in 2014, brrr° is a relatively new fabric
technology that incorporates salts and natural
minerals into the extrusion mix for a synthetic
textile that has cooling properties. Mary Jane
Credeur, speaking on behalf of brrr°, describes
this as a cooling technology integrated into a
polyester or nylon blend. "The secret sauce,"
she says, "is a master blend of salts and cooling
minerals" that was developed in 2014 by a
team led by Mary-Cathryn Kolb, the former
director of sales for SPANX®.
Basically, the salts and minerals are
pulverized and then added to the polymer.
The technology is a component of several
high-end products, including golf apparel
from Greyson and women's dresses from
Southern Tide®.
BREAKING DOWN DEGRADATION
Other companies are adding biomaterials
to synthetics, such as polyester, to facilitate
a process similar to biodegradation. That,
however, is what Dr. Sonja Salmon, associate
professor of textile engineering at NC
State's Wilson College of Textiles, describes
as a "complicated space," due to potential
misunderstandings related to the various
stages of a textile's decomposition.
The first step, Salmon says, is deconstruction. This is where a textile product is taken
apart. The next step is disintegration where a
textile is physically broken apart into smaller
microscopic fragments. The last is degradation, which refers to a chemical conversion of
a larger or more complex chemical structure
into simpler chemical structures. A subgroup
of degradation, she adds, is biodegradation,
where the remaining particles go through
a chemical conversion into energy that can
be consumed.
"When you eat something, you are
biodegrading it," she says, "and those layers
are very important when we start talking
about polyester or other acrylics."
California state law, for example, has
strict rules related to the use of the word
"biodegradation" in connection with any
polyester product. California law SB 567
prohibits any plastic product sold within
the state to be labeled as "biodegradable,"
"degradable," "decomposable" or any form
of those terms.

SUSTAINABLE SYNTHETICS
The makers of CiCLO® additive technology,
a new fiber option in the textile industry
supply chain, have taken that guideline to
heart as they bring a new, more sustainable
synthetic fiber technology to market. CiCLO
chemistry is added to polymers during the
extrusion process, which helps fabrics, such
as polyester, break down in a way that's
similar to wool at the end of a product's life
cycle. According to materials from Parkdale
Mills, which is marketing the new fiber to
the textile industry, the additive technology
accelerates the speed at which a synthetic
fiber biodegrades in the ocean or a landfill.
CiCLO is a product of California-based
Intrinsic Textiles Group LLC, which was
formed to develop and commercialize
sustainable, closed-loop solutions for textiles.
According to Cheryl Smyre, brand manager
and director of advanced materials at Parkdale,
apparel manufacturers can easily integrate the
technology into their supply chain.
She adds that brands in the performance
sector are looking to manufacture apparel
made from synthetic fibers in ways that
pollute less, without losing the performance
strengths of synthetics such as polyester
and nylon.
"Extensive testing by reliable third-party
laboratories over a number of years has proven
that CiCLO technology is effective at reducing
synthetic fiber accumulation in landfills and
microfiber pollution in the oceans," Smyre
says. "At the same time, products made from
CiCLO additive polyester can be washed and
cared for just as you would any other polyester
apparel item."
She adds that CiCLO fibers and yarns can
play a role in reducing the impact of textile
waste in landfills and synthetic microfibers
in the oceans generated by the high volume
of personal protective equipment (PPE) that
will be used as the world fights the COVID19 pandemic.

A NUMBER OF
NATURAL MATERIALS
ARE BEING USED
BY THE TEXTILE
INDUSTRY TO
DEVELOP BIO-BASED
FABRICS OR FABRIC
BLENDS, INCLUDING
MILK, CORNSTARCH
AND ALGAE.

PLANT-BASED PERFORMANCE
Other companies in the outdoor apparel
and gear sector that are using biomaterials
to replace or supplement synthetics include
NEMO Equipment Inc. and Reima USA.
NEMO is a camping gear brand that sells
sleeping bags and tents, among other products.
