Ontario, Canada, (May 1st, 2005.) -- Thomson
Research Associates today announcedthe introduction
of Ultra-Fresh Silpure , the new
generation silver-based antimicrobial treatment
for textiles. Ultra-Fresh Silpure enables textile
manufacturers to add superior odor and fiber-degradation
resistance to their products through the use of
a powerful antimicrobial substance – metallic silver.
Ultra-Fresh Silpure ,
the newest development in the Ultra-Fresh® family
of products, represents a breakthrough in the use
of silver-based antimicrobials for the textile
market. Ultra-Fresh Silpure is applied at the finishing
stage for more complete protection of the fabric,
and has been proven in tests to be consistently
effective, with no tendency to cause discoloration.
The superior performance of this new generation
silver-based antimicrobial has been achieved by combining
application expertise developed over 50 years of
Ultra-Fresh treatments with proprietary nanotechnology
manufacturing processes for the metallic silver.
The ultra-fine particles adhere more effectively
to fibers for longer protection.
Ultra-Fresh Silpure has broken the cost barriers
which have restricted the use of silver- based antimicrobials
in the past.
A natural antimicrobial
Silver containers have been used to keep their contents
pure for centuries. Investigations into the ability
of metallic silver to inhibit the growth of bacteria
began in the late 19th century.
The result was a number of pharmaceutical products
intended as dressings for wounds and intreatment
of eye infections, many of which are still in use.
However, the cost of silver and the technical challenges
of reducing the metal to the ultra-fine particles
necessary for optimum performance limited its applications.
Ultra-Fresh Silpure promises ease
of application for cost-effective use and long-lasting
protection for optimal performance. Plant trials
have established that antimicrobial performance of
Ultra-Fresh Silpure remains strong after 50 or more
washes -- a powerful benefit for consumers of sports
and leisure wear. In plant trials, using typical
application processes on 100% polyester fabrics,
bacterial survival was less than 0.1%, even after
"Previous cost barriers to the wider use of silver
have been overcome," says Dr. Laval Yau, president
of TRA. "Now, silver antimicrobials are no longer
confined to niche markets. They can be used effectively
and profitably through the broadest range of consumer
The Ultra-Fresh brand, introduced
by Thomson Research Associates is now used by more
than 200 companies in more than 30 countries. Seen
on a wide range of products and in magazine, radio
and television advertising, the brand and its logo
promise the highest standards of antimicrobial protection
in clothing, household textiles, and many other applications.
