Industrial demonstration of alternative DWOR due to begin in the next months!

MIDWOR-LIFE is already working with the six companies that will participate in the industrial demonstration of the alternative DWOR products that have been selected together with them for five different applications, namely workwear, upholstery, fashion, automotive carpets and sportswear.

 
 

Results of the laboratory demonstration and characterization

b1 

Textile researcher Marolda Brouta (LEITAT) comments on the lab demostration results:

"The most interesting result is the very good water and oil repellency demonstrated by perfluorosilicone product, before and after ageing, and with highest values than C8 chemistry. Perfluorosilicone combines a soil release and water and oil repellency property. Moreover, this technology includes the anchorage of the fluorocarbon chains to the substrate to improve the orientation of the fluorocarbon chains.
On the other hand, the Silicone product is highly effective on nonwovens but do not present oil repellency since its surface energy is higher than the surface energy of oil."

Fluorocarbon-based chemistries and sol-gel are also discussed in the complete report available on the project's website.

 
 

European Stakeholder workshop in Barcelona

  Stakeholder discussion

On March 15th, the MIDWOR-LIFE project team, coordinated by AEI Tèxtils - the technical textile cluster of Catalonia-  and Euratex co-organized a workshop, at the Casa de la Seda in Barcelona, as part of its wider strategy towards the replacement of harmful chemicals in textile industry.

The workshop gathered participants from the chemical industry, textile associations, testing laboratories and research institutes. The aims of the workshop were twofold: to present the latest MIDWOR results assessing safer alternatives to durable water and oil repellants (DWORs) such as PFOA and PFOS in the textile industry and to launch a first discussion on the matter by bringing together European experts with different competencies and perspectives.

Perfluoroctanoic acid (PFOA) and related substances have been used in a variety of consumer products for many years.

One of the significant uses of the substance has been used to provide water-resistant coatings to textile products. PFOA-related substances have also been used to provide stain-resistant coatings to apparel, other textile products and to carpets.

MIDWOR-LIFE project is evaluating alternatives to conventional Durable Water and Oil Repellants used for functional textile finishing.

Study from research group at University of Leeds finds that many waterproof outdoor wear is over-engineered for purpose

  raincoat-1245688

New research from the University of Leeds suggests that the use of controversial fluorochemicals in the manufacture of most of these garments may be unnecessary. In addition to subjecting samples of 22 different fabrics to extensive chemical analysis and testing, the Leeds team surveyed 575 outdoor enthusiasts who regularly participate in hiking, trekking, mountaineering, and hill-walking, about how they used such clothing. 

“We found that 82% of people considered water repellency to be the most important factor, but the majority of people were indifferent to levels of stain resistance and oil repellency – one participant even said ‘I don’t get oily when walking’," said Philippa Hill, whose PhD research is the subject of the paper.
