Crypton and NANO-TEX together at last

Leave a reply

A Jan. 6, 2014 news item on Nanowerk notes that Crypton Fabrics has purchased NANO-TEX,

CRYPTON INC. has acquired NANO-TEX®, announced Randy Rubin, Chairman of The Crypton Companies. The privately held, 20-year-old Crypton Fabrics, based in Bloomfield Hills, Michigan, recently purchased NANO-TEX from private equity and venture capital investors; WL Ross and Co. LLC as major stockholders, in addition to Norwest Venture Partners, Masters Capital Nanotechnology Fund, Firelake Capital Management and Masters Capital Management.

NANO-TEX is a textile technology company whose performance finishes have enhanced leading consumer brands such as GAP, TARGET, MAIDENFORM, BASS PRO SHOPS, NORDSTROM, LAND’S END, FISHER-PRICE and many more.

The Jan. 6, 2014 Crypton (there has to be a Superman or inert gas enthusiast in that company) press release, which can be found on this page under this title: Silicon Valley to Motown, Performance Textile Leader Crypton Purchases Nano-Tex, explains why the NANO-TEX acquisition was so attractive and what it means to NANO-TEX’s major stockholders,

NANO‐TEX employs a proprietary nanotechnology approach to enhance textiles at the molecular level that provides permanent performance attributes such as stain and water resistance, moisture wicking, odor control, static elimination and wrinkle free properties. The end result is performance fabrics that maintain the original comfort, look and feel of the fabric and perform for the life of the product.

In 2013, NANO‐TEX technologies were on $280 million in branded finished products at retail worldwide.

Wilbur Ross, Jr., Chairman of WL Ross said, “We are extremely pleased by Crypton’s acquisition. This assures that NANO‐TEX will continue on a strong growth trajectory. Its expanding market reach and prominence will further enhance the competitiveness of WL Ross’s companies in the consumer and industrial fabrics industries, too; the goal that sparked our initial investment interest in NANO‐TEX eight years ago.”

It seems there was a specific product which attracted the Crypton team’s attention,

“This is a strategic acquisition as we extend our market share with apparel throughout the world. The intellectual properties and latest development, Aquapel®, a non‐fluorinated repellency treatment, is very exciting to our research team,” said Rubin.

There’s more about this product on the NANO-TEX Aquapel® page.

On a completely other note, at least one NANO-TEX product has silver in it according to a 2007 entry on the Consumer Products Inventory (Project on Emerging Nanotechnologies),

They Say:

“Nano-Tex™’s revolutionary technology fundamentally transforms fabric at the nano-level to dramatically improve your favorite everyday clothing.”

Nanomaterials:

Silver

Potential Exposure Pathways:

Dermal

How much we know:

Category 4 (Unsupported claim)

Additional Information:

Generic Product

Crypton too has silver in at least one product (from the INCASE Fabric Protection FAQs),

Q:  How does INCASE™ resist bacterial growth?
A: Silver Ion technology is used in INCASE to inhibit the growth of a broad spectrum of medically relevant microorganisms, including bacteria. Silver is one of nature’s original antimicrobials. Used thousands of years ago by Greeks in vessels to preserve water and wine, the natural benefits of silver have now been tapped to keep fabrics odor-free.

Cyrpton’s INCASE product uses sliver ions, which according to some research at Rice University (based in Texas, US), are more toxic than silver nanoparticles, from my July 13, 2012 posting,

He [Pedro Alvarez, George R. Brown Professor and chair of Rice’s Civil and Environmental Engineering Department] said the finding should shift the debate over the size, shape and coating of silver nanoparticles. [emphasis mine] “Of course they matter,” Alvarez said, “but only indirectly, as far as these variables affect the dissolution rate of the ions. The key determinant of toxicity is the silver ions. So the focus should be on mass-transfer processes and controlled-release mechanisms.”

Crypton’s About page strongly suggests an environmentally friendly and health conscious company (Note: Links have been removed),

Innovation. Industry leadership. A deep commitment to product excellence. These core elements are at the heart of the Crypton DNA – a labor of love that began in 1993 when founders Craig and Randy Rubin set out to create a new generation of stylish fabrics that were moisture-resistant and easy-to-clean, yet soft, comfortable and breathable.

From the basement of their Michigan home, a textile revolution was born.

Now based in West Bloomfield Michigan, with a green manufacturing facility in Kings Mountain, North Carolina, Crypton is the only textile solution in the world offering complete stain, moisture, mildew, bacteria and odor-resistant protection thanks to a patented process developed by some of the leading minds in the textile industry.

Early on, by offering a fabric – not a vinyl or plastic – that was capable of resisting stains, moisture, odors and bacteria, Crypton proved to be the perfect solution for the health care market. Following this initial success, Crypton solutions rapidly expanded into some of the finest restaurants, hotels, cruise ships around the world, as well as government complexes, schools and health care facilities.

Now trusted and relied on by over 90% of contract designers, there are more than 20,000 patterns of Crypton fabric available today. Crypton is the only fabric deemed a non-porous surface and can be disinfected when used in conjunction with our U.S. EPA-approved Crypton Disinfectant & Deodorizer.

From fabric, carpet, leather, wall and mattress to pet beds, home accessories, bags and luggage – our mission is to give customers more ways to live healthy, live beautifully and Live Clean®.

While there is no incontrovertible proof that silver nanoparticles and/or silver ions are a serious threat to the environment, it would be nice to see companies acknowledge some of the concerns.

University of Alberta scientists sniff dirty clothes

Leave a reply

Bev Betkowski’s June 22, 2012 news item on physorg.com notes,

Using state-of-the-art techniques for molecular separations in a U of A [University of Alberta] chemistry lab to analyze a pile of sweaty T-shirts worn and washed by 18 study participants, lead researchers Rachel McQueen and James Harynuk joined forces to tackle the problem of stinky workout gear.

The news item which originated in a June 22, 2012 news release from the University of Alberta describes the experiment,

McQueen, an assistant professor in the Department of Human Ecology, teamed with Harynuk, an assistant professor in the Department of Chemistry, to put specially designed T-shirts—two for each participant—to the test in a field trial lasting 10 weeks.

The stack of 36 shirts was specially sewn with two test fabrics—untreated cotton matched either with untreated polyester or with cotton treated with a silver-chloride antimicrobial, designed to fight odour-causing bacteria in sweat. Participants wore the bisymmetrical shirts when exercising, then washed them after each workout.

For the research, the underarms were cut from each T-shirt. The washed and unwashed versions were analyzed for bacterial counts. Using high-tech methods—gas chromatography and mass spectrometry— in Harynuk’s lab, the odorous molecules were also examined.

The compounds in the sweat were separated and analyzed, with individual molecules being identified. The analysis revealed between 1,000 and 2,000 compounds in the odour profiles of each shirt.

…

“We may find ways to target compounds in the process of designing textiles that don’t retain certain odour-causing molecules.”  [said Harynuk]

Here’s what they discovered,

Their research showed that, for less reek in workout gear, cotton is better than polyester. The experiment also revealed that the T-shirts treated with the antimicrobial finish were not effective in cutting body odour.

“Fabric options vary for workout clothing, but for anyone concerned about body odour, cotton would be a preferable choice,” said McQueen.

That finding about silver nanoparticles definitely contradicts what I understood to be true.  Their conclusion is also a little unexpected,

“Ultimately, the ideal is to find a formula for an odour-resistant textile that can be washed less frequently between workouts, resulting in a more sustainable garment,” she added.

The challenge is in changing the perception of soiled clothing, she noted. [emphasis mine]

“An item may not look dirty, but it smells dirty when people do the ‘sniff test.’ If clothing didn’t look or smell soiled, people might be willing to wear something more than once or twice before throwing it in the laundry—which would really be better for the environment.”

So, changing how clothes smell after a few wearings could help save the environment. If that works, why not do it?

Textiles that can detect counterfeiting devices, bacteria, and dangerous chemicals; a 22 nm chip; copyrighting food?

Leave a reply

I’m going to watch at least part of the live stream for the PEN event (Transatlantic Regulatory Cooperation) that’s taking place this morning (9:30 PST), so this is going to be a quick posting.

In my master’s project (The Nanotech Mysteries wiki), I featured a 2007 news item about a student designer at Cornell University who used textile fibres coated with nanomaterials in her clothing designs. (You can see the wiki page here.) Today, I caught a news item on Azonano about some textile scientists at Cornell University who launched a start-up that markets these kinds of fabrics.

Fabrics with embedded nanoparticles to detect counterfeiting devices, explosives and dangerous chemicals or to serve as antibacterials for hospitals, law enforcement or the hospitality industry are just a few of the products that a new company, [iFyber LLC] launched by two Cornell researchers, will produce.

This is exciting as I’ve gotten to follow the story a little further than usual. Generally, I find out about a product and then learn that it had its origins in an academic laboratory.

Intel has announced a new 22 nanometre (nm) chip. From the news item on Nanowerk,

Intel President and CEO Paul Otellini today displayed a silicon wafer containing the world’s first working chips built on 22nm process technology. The 22nm test circuits include both SRAM memory as well as logic circuits to be used in future Intel microprocessors. “At Intel, Moore’s Law is alive and thriving,” said Otellini. “We’ve begun production of the world’s first 32nm microprocessor, which is also the first high-performance processor to integrate graphics with the CPU.

I posted about the 32 nm chip and Intel’s investment in retooling three of their manufacturing facilities to produce the chip here. As I recall, IBM has a 28 nm chip.

I’m not sure what to make of all this. I find these innovations exciting but I always wonder about the practicalities. Since these chips aren’t visible to the naked eye, how does your computer get fixed (e.g. chip replacement) by your average computer repair shop? How reliable are these chips?

Finally, here’s a posting I found on Techdirt about copyrighting hummus, etc. There is a group in Lebanon who are planning to sue  Israel for using words like hummus, tabbouleh, etc. to describe their food products. It seemed a little odd to me when I scanned the headline but as Techdirt sardonically points out, the word champagne is for the exclusive use of wine producers in  France and there have been other successful attempts at this type of copyright claim. (As I recall,  not even French wine producers from  regions other than Champagne can call their product champagne.) I followed one of the Techdirt links here for more information. My understanding after viewing a tv clip and reading the article (both Israeli-produced) is that the Lebanese group is motivated by the fact that Israel has been more successful at marketing and selling these products internationally.  I also wonder how the other countries that market and sell these products will react to Lebanon’s proposed copyright claim.
