Restriction of perfluorooctanoic acid (PFOA)

and PFC-free alternatives for hydrophobisation
Water-repellent finishes are used in many different textiles and it is hard to imagine daily life without them today. No matter whether it is outdoor furniture, the awning on the patio, hiking outfits, work clothes or technical textiles - fluorine-based hydrophobisation often achieves the desired water- and dirt-repellent effect.

However, as early as 2013, PFOA, its salts and precursors were ranked by the European Commission as being substances of very high concern. A tenacious struggle ensued, but was not able to prevent the edict that from July 2020 onwards it would no longer be permissible to put PFOAs into circulation in concentrations of 25ppm or higher.

The dangers and above all the health risks involved with these substances are immense. In the jargon, perfluorinated and polyfluorinated chemicals are regarded as persistent, bioaccumulative and toxic. But what do these terms mean?

These substances are toxic, and thus poisonous, as they have been proven to damage the immune system, particularly in children, to have a negative effect on fertility and to lead to the increased occurrence of cancer .  
With respect to environmental chemistry, the resistance of compounds to degradation processes is described as persistent. Persistent compounds remain unchanged by physical, chemical or biological processes for long periods, thus leading to undesired accumulation, also in the food chain (bioaccumulation).

While numerous companies in the textile industry are now apparently only just begin to search for PFC-free alternatives, TWD Fibres is already one decisive step further. With the optional yarn finish “Green FC Free”, it offers a fluorine-free hydrophobisation for all DIOLEN® polyester and TIMBRELLE® PA 6.6 yarns.

One flaw that has marred the established PFC-free hydrophobisations so far - lack of wear resistance in household washing - does not apply to this alternative in any way. “We’re aware of this problem, of course, particularly with paraffin-based products, and that’s why we have specifically been looking for alternatives that will also meet our customers’ requirements with regard to wear resistance. And it’s precisely this issue that we also subjected to special observation in standardised test procedures according to DIN EN ISO 4920 (spray test) and DIN EN 29865 (sprinkler test) in two different laboratories. In these tests, it wasn’t only the brand new woven goods that proved to have very good hydrophobic properties, obtaining grade 4 (on a scale from 0 to 5), but the results for knitted goods were also impressive. The water-repellent properties were then repeatedly retested using a spray test at intervals of five or ten washes. So we can say with a clear conscience that we can still achieve a clearly recognisable water-repellent effect even after 50 washes,” Dr. Oliver Bensch  (CEO, TWD Fibres). “This makes Green FC Free a harmless, ecological alternative to conventional hydrophobisations.”

Fighting plastic in the oceans

100% recycled PET - Polyester yarns DIOLEN®ReCIRCLE

In 30 years will be more plastic bags and bottles swimming in the oceans than fishes. This horrifying pictures was drawn in this week by UN Secretary General António Guterres while the UN Maritime Conference in New York. He invited all participants from nearly 200 different countries to overcome their territorial and national interests and fight together for a more careful dealing of the oceans.

What is sad on this: there are already functional strategies and proven products that could minimize each personal contribution to plastic in the seas. One example in the textile industry are polyester textiles made out of recycled plastic bottles.

48 PET bottles with a capacity of 1.5l are used to produce one kilogram of DIOLEN®ReCIRCLE yarn.*
