more unethical behavior

A TESTIMONIAL FROM A LONG TIME CUSTOMER; I.E. A FRIEND

Well it finally happened....after just short of 60 years of all kinds of camping I ended up with a wet sleeping bag. I've always been very careful to always have the bag in a waterproof cover of some sort but screwed up last weekend when camping with some friends.
The tent was a single wall Cabela's Outback Lodge that I usually have a Kelty Noah's Tarp over if it is going to rain. But I didn't and when it poured Sunday when we were away from camp everything in the tent got wet. Worse I didn't discover it until just before bed. So I moved into one of my friend's Adirondack shelters and slept on a cot.

Now I have heard that if a Wiggy's bag gets wet, and this was my pushing 20 year old Nautilus that's been washed 30+ times, if one climbed in the bag would warm up quickly and be dry by morning. So rather than digging out the wool blankets I keep in the truck I decided to try it figuring if it didn't I'd just go get the blankets.

Had on a t-shirt, underwear and socks, crawled into the wet bag and in a minute began to feel warm...fell right asleep as usual. Woke up a few hours later and got up to go to the bathroom to find that most of the bag was dry. When I got up in the morning the only part of the bag that wasn't dry was the area of the final foot or so of the zipper.

Monday when I got home put the bag in the washer with a cap full of SportWash. Then put it over the deck rail for about 2-3 hours and it was like new again.

Preventing permastink goes beyond antimicrobial solutions

The effort to eliminate body odor seems incredible to me.

September 1st, 2017 / By: Debra Cobb / Advanced Textiles, Markets

Are you sure you wish to continue?

Conventional solutions for preventing permastink—the unpleasant smell that won’t wash out of textile products—focus on using antimicrobials to inhibit the growth of odor-causing bacteria. New technologies trap, adsorb and eliminate odor so that consumers don’t perceive it.

I do not believe that new technologies actually exist!

It’s everywhere and it’s not attractive. Permastink—the unpleasant smell that won’t wash out of textile products—has become a topic of conversation for consumers and brands alike. Polyester and other synthetic fibers are the materials of choice for the active performance and athleisure styles consumers now wear throughout the day. Unfortunately, these synthetic fibers are perceived as being smellier than natural fibers, according to a 2008 wear trial at the University of Alberta, Edmonton, Alberta, Canada.

I have never heard people talking about this at all let alone as some sort of problem.

What causes permastink?

Malodors are created by the breakdown of bodily secretions into various compounds by bacteria on the skin. These compounds may include methanethiol, hydrogen sulfide, propanoic acid and isovaleric acid. They create a chemical bond with performance fibers, locking permastink into the fabric.

Is this a new set of bacteria from the human body or is it on going since the inception of humanity but somehow at this time it is now a problem.

Consumers are choosing to save energy by washing textile products at lower temperatures, and most performance fabrics recommend a low temperature wash. As a result, higher levels of odor-causing bacteria remain on untreated articles even after laundering.

Yes, I only use cold water in my washing machine and believe it or not my clothing natural fiber, mostly cotton and all of the polyester and nylon garments come out of the dryer come out odor free. No malodors at all. Their last sentence is non-sense.

“With permastink, garments don’t wash clean, and brands get returns,” says Lisa Owen, vice president of global textiles at Microban® International, Ltd., Huntersville, N.C., a provider of antimicrobial technologies and odor control solutions. “It’s quite a problem in the industry.”

Lisa wants to sell her chemicals so she is creating the returns senerio.

“Once odors lock into untreated synthetics, they are difficult to remove,” confirms Lee Christie Stapleton, director of training and education at Sensory Spectrum, a New Providence, New Jersey-based global management consulting firm specializing in understanding the sensory consumer experience. “How can we prevent that from happening?”

What the hell is a sensory consumer experience? Lee belongs in the looney bin as Lisa.

Killing microbes, not odors

Conventional solutions for preventing malodors on textiles focus on inhibiting the growth of odor-causing bacteria through the application of antimicrobials, either built into fiber or applied during the textile finishing process. While many of these successfully reduce the amount of bacteria, there is a wide variation in efficacy and durability of these formulations—and in the methods used to test and measure them.

What they leave out in the above paragraph is the fact that there antimicrobials otherwise known as pesticides are leached into the skin of the person wearing the garment; wonderful!

The International Antimicrobial Council (IAC) lists five different test methods for measuring the performance of standard antimicrobial treatments. The IAC recommends that these tests be performed and verified by IAC-certified labs. In general, the tests seek to assess the bactericidal activity of the test agent as well as its inhibition of bacterial growth. But if technology supplier A uses a different test method than that used by technology supplier B, is it possible to truly compare the efficacy and durability of the two antimicrobial technologies?

They are actually testing to see how much of the pesticides are leached into the skin!

Woodhead Publishing’s 2016 “Antimicrobial Textiles,” edited by Gang Sun, questions the validity of current test methods: “All these methods simulate optimum efficacy conditions for antimicrobial agents. … But these conditions, except sportive activities, normally do not occur during practical wearing. … Thus it is possible that textiles will be regarded as antimicrobial, but under practical wearing or environmental conditions, there is no, or a highly reduced, antimicrobial effect.

Good point, they do not know how the pesticides actually adversely affect the human body, but they do know it does.

“Another problem is that not every antimicrobial agent on the textile shows an antimicrobial action with every test method. Thus the comparability of the different methods is complicated, additionally.”

Complicated; when people get rashes you know what has caused them, the pesticides!

When it comes to their use on apparel textiles, antimicrobial technologies have other issues, including the growth of bacterial resistance and the leaching of silver or other antimicrobial agents. But the bigger question is: Does the reduction of bacteria actually prevent, block or remove odor on the textile?

Now we are getting somewhere, since they are publicly questioning if the pesticides have any positive affect at all, the answer is a resounding NO!!!

Odor adsorption

As it turns out, there are other options.

You could drink the pesticides and the end comes sooner. Not a good option.

“You have products that inhibit microbial growth. But there are other technologies that trap odor so that you don’t perceive it,” says Stapleton. “Preventing the malodor is the game in apparel. The more you can deactivate—‘eat’ the odor—you prevent it from getting to the permastink category.”

See, eat the odor? Lee should immediately return to the looney bin.

The concept of trapping, adsorbing and eliminating odor using activated carbon particles or cyclodextrins is well-known to hunters and gamekeepers. In 1992, a company called ScentLok first developed hunting apparel containing activated charcoal to block human scent so the game being hunted wouldn’t smell the hunters’ presence.

I have hunted and I could have been wearing a clown costume and bathed in pickle juice and still had the kill since I was 200 plus yards from the animal. I personally think scentlok is non-sense.

Owen says that carbons and cyclodextrins have shortcomings, however, such as cost, binders, discolorations and durability. A number of textile technology suppliers are now commercializing new versions of odor adsorption treatments for apparel textiles using substances such as zeolite (a mineral formed when volcanic ash reacts with alkaline groundwater) and alumina silica. The large surface area of these minerals attracts and adsorbs odor molecules.

Odor absorption is nothing more than a product to make a buck, no purpose. What did Dan Boone smear on himself. Hell of a hunter from reading much of his life story and the same holds true for all of the mountain men of his era and today.

The products’ efficacy can be proven by ISO test 17299, which measures deodorization rates via gas chromatography. Standards are also established by the Japan Textile Evaluation Technology Council (JTETC).

Step right up and get your certification from JTETC!

“There’s art and there’s science when it comes to measuring odor,” says Stapleton. Sensory Spectrum recognizes three methods for evaluating odor: microbiological detection, gas chromatography and the use of experts trained to identify and evaluate the strength of odors to a scale.

Lee is out of the bin again; what is the art, a twisted nose and of course the science a straight nose. Get yourself a trained expert sniffer to advise you of the chemical odor that you are exhibiting. Do these experts go to smeely school to learn their trade?

“Odor compounds aren’t necessarily good or bad—it’s about the context,” Stapleton says.

Cn somebody explain that comment from the looney bin for me?

My next comments are at the end of this article.

A platform of solutions

Based on zeolites, Wakefield, Massachusetts-based Sciessent’s LAVA XL™ technology attracts, adsorbs and degrades odor molecules, avoiding saturation and allowing the product to regenerate between launderings. The bluesign®-approved formulation can be combined with Sciessent’s Agion® silver ion-based antimicrobial to create Agion Active XL with dual-function odor control.

Just introduced, Swiss company HeiQ’s Fresh NKU goes beyond adsorbing body odor deriving from bacterial sweat metabolites to sequestering volatile malodors like the “plastic” smell of polyester, new upholstery or body hormones. The large surface of the alumina-silica microparticles in Fresh NKU immobilizes unpleasant volatile odor compounds, turning them into non-volatile, and therefore non-perceivable, odor compounds. HeiQ is also planning to release a product combining Fresh NKU with its silver-based antimicrobial technology.

Scentry®, Microban’s odor control solution for textile product applications, was introduced as a novel solution to the problem of adsorbing and trapping the body odorant compounds released by bacteria—blocking the formation of permastink, according to Brian Aylward, director of liquid formulations, R&D, at Microban. Applied as a finish, Scentry creates a barrier layer on the surface of the textiles, trapping the odors and preventing them from bonding with the fabric. Washing the textile with water and detergent releases the trapped odors and recharges the treatment.

“The technology is completely different from antimicrobials and is capable of reducing the amount of odor building up in a textile over time,” says Aylward.

Scentry has already been commercialized with the hunting and outdoor apparel brand Hook and Bullet, where odor adsorption commands a premium. A number of trials are being run in the performance and leisure wear segments, according to Owen. The technology has received the bluesign system blue product designation and can be combined with Microban antimicrobial-based technologies to provide 360-degree odor control, the company says.

Microban has also developed Scentry for polymers, which will function as a built-in solution for consumer products using recycled polyethylene terephthalate (PET), for example. “Scentry is part of a platform of customized solutions, built on our odor management expertise,” says Owens.

Korean textile producer Hyosung also sees the merit of polymers that can chemically neutralize odors in textiles. Its creora® Fresh is a functional spandex that chemically neutralizes odors such as ammonia, acetic acid and isovaleric acid, keeping textiles smelling fresh.

Because the deodorizing function is in the polymer, it is more durable than textile coatings or finishes and is particularly effective in textiles that come in direct contact with the skin, such as underwear, sportswear and hosiery.

“At the consumer level, all ages continue to focus on health and wellness, with increased participation in exercise,” says Ria Stern, Hyosung textiles global marketing director. “In socks for running or walking, creora Fresh adds compression, support and odor-neutralizing benefits with technology built into the fiber for more durability. In sports bras and underwear, we are working with brands and retailers who want to move away from having antimicrobial chemicals next to skin.”

Hyosung has also developed freshgear® polyester and MIPAN freshgear nylon as solutions for controlling odors in apparel fabrics.

What’s clear is that no one method of odor control will work in every situation. While some brands may prefer to prove odor reduction by counting bacteria in the lab, others can now choose a more sensory approach. Meanwhile, technology providers continue to develop new solutions to the problem of stinky textiles.

All I know at this time is if you are not chemically sensitive wearing these garments next to you skin will ultimately cause you to become chemically sensitive. I knew a person who was not chemically sensitive and worked in an atmosphere where chemicals were used and after a year or two they became seriously chemically sensitive.

I have sold hundreds of sleeping bags to chemically sensitive people over the years because there are no chemicals used on the materials I use. There is a web site for chemically sensitive people who list my bag as the one that does not affect them. The number of chemically sensitive people is increasing I believe because the textile industry is processing materials with these pesticides which is what they are, not antimicrobial chemicals which is just a fancy name for pesticides.

And since so much of these garments are made in China or possible North Korea these days who knows what the chemicals are that they are bathing the fabrics in? If the garments are not made in the USA where the company that makes them can show you in black and white that they are only using materials that have no treatment on them don’t buy them.

We are living in what I believe are tragic times, with more immoral and unethical behavior!
