Washington Gov. Jay Inslee signed the first state law to ban toxic fluorinated chemicals in food packaging, such as microwave popcorn bags, pizza boxes and fast-food wrappers. The ban – conditioned on the state identifying a safer alternative – is a major defeat for the chemical and packaging industries, which have quashed similar proposed bans in other states.

From EcoTextile News:
Research raises questions over short chain PFCs
Written by Brett Mathews
CALIFORNIA – US researchers have released study findings which indicate that short-chain fluorinated chemicals actually accumulate in the body for longer – and at higher concentrations – than their long-chain counterparts. The findings come at a time when many apparel brands, particularly those in the outdoor sector, are shifting away from long-chain (C8) chemistry and towards short-chain (C6, C4) alternatives in their fluorinated repellents on the basis that the latter represents a more environmentally benign option.
In the study, three types of fluorinated chemicals, two short-chain compounds and one long-chain, were radio-labelled and injected
into mice. By following the radiolabels with a standard nuclear medical technique, the researchers could then identify which of the three chemicals was found in which organ and at what levels. These
chemicals were found to migrate in the liver, stomach, leg bone, lungs, kidney, heart, skin, muscle, brain and other organs of mice after injection of the very high dose of radio-labelled
All three types of PFAS compounds were found to bind to blood and to be transported to every mouse organ studied. “What was unexpected was that the safe short chain alternatives were found in higher levels in about half of the organs studied than the phased-out long chains,” says a note from the US-based Green Science Policy Institute. “This paper supports previous work from a Spanish research group that found short-chain PFAS chemicals in a variety of organs in human autopsy tissue.
“The results of the research were surprising, and have potential human health implications far beyond this initial study.”
Dr. Graham Peaslee, a co-author on the study from the University of Notre Dame, claimed the results call into question the safety of alternative shorter-chain PFAS compounds being used in consumer goods.
The research findings look likely to sound a further death-knell for the fluorinated chemistry industry and increase calls for a ban on the use of such chemistry in the European Union. However, with regards the use of fluorinated repellent coatings used in the apparel industry it is implausible that the high levels of fluorinated chemicals that the mice were subjected to, would ever be replicated by simply wearing a garment with a PFC-based coating – be it C8 or C6 chemistry.
Dose is an important factor that cannot be ignored.
However, Dr Arlene Blum of UC Berkeley and the Green Science Policy Institute noted: “Highly fluorinated chemicals—also known as PFASs or PFCs—are used to give water-repellent, stain-resistant, and non-stick properties to consumer products such as carpets, outdoor gear, clothing, cosmetics, cookware, and food packaging. We should ask whether we really need fluorinated materials in products with (any) human exposure.”

Full-width, high pressure, dry finishing capability at GTT
GTT is proud to announce that it now has added capability for finishing of full width fabric at high pressure using its proprietary, water-free, fluorocarbon-free finishing technology. The pressure pod shown in the photo consists of 1 cm thick steel and is ASME certified for operation up to 500 psi = 35 Bar = 3.5 MPa. The unit weighs about 500 lbs = 227 Kg. The pressure pod can handle rolls of treated fabric up to 68"= 1.7 m width and up to 91 m long.
GTT has shown that high pressure dry curing provides performance benefits well beyond wet finishing and atmospheric plasma finishing. High pressure technology is especially well suited for thick fabrics, such as fleece, membrane fabrics and nonwovens and provides the highest possible performance for sports apparel, upholstery and outdoor fabrics.

Greenpeace slams major outdoor apparel brands
Greenpeace collected 40 products from major outdoor apparel brands, including bags, jackets, trousers, tents and sleeping bags and sent them to an independent laboratory for analysis.
All but four of the products were found to contain PFCs. And 18 of the products contained the more harmful and persistent long-chain PFCs, which most of the tested brands have stated they no longer use. To read the article, click here.
This demonstrates that even products produced after the C8 fluorocarbon ban are still found with PFC, including C8-type PFCs.
GTT has the best performing PFC-free DWR treatment, making the use of PFCs unnecessary.

GTT Technology Breakthrough: Hyper- Baric Dry Finishing!
GTT is excited to announce that it has ushered in a new era of dry finishing: high pressure finishing technology. Further expanding its lead in dry finishing, GTT has developed and is commercializing its proprietary hyper-baric dry finishing technology. This process technology is ideally suited for tightly woven or knitted fabric and technical textiles in which the highest water repellency performance is needed - and without perfluorinated chemicals. As in the standard GTT approach, the ChemStik® treatment is applied to the fabric at room temperature. The coated fabric is then placed into a "Pod", a pressure vessel, where it is pressurized to 10-25 Bar. This "pushes" the coating in between fibers (even for tightly spun fibers). Then, the Pod is heated to thermally cure the coating, ensuring that the polymer stays in place even when the pressure is released. This process is environmentally-friendly, as no gases or waste chemical is released. The low cost of a Pod and the capacity of a Pod to hold hundreds of yards of coated fabric means that the mill throughput is unaffected by this continuous batch process and the capital equipment cost remains low. It also frees up the stenter. Further details to be coming.
