CETIM participates in the meeting of the second annuity of the MIDWOR-LIFE project

MIDWOR-LIFE, is a project co-financed by the LIFE + program of the European Commission that aims to reduce the impact on the environment, health and safety of the current DWOR (chemical repellent chemicals) used in the industry textile and its future alternatives, analyzing its environmental impact and its functionalities.

On October 3, the half-yearly meeting of the MIDWOR-LIFE project was held in Città Studi (Biella) organized by the Italian partner Pointex, in which all the project partners participated.

The meeting began with the presentations of the progress and results of the different actions carried out during the last 6 months. Each partner also presented the planning for the next months, followed by an open debate among all the members of the consortium to evaluate and propose the strategic and operational lines for the next months.

The main results of the last semester are the publication of the B1.1 deliverable: “Report of the application and characterization of the current DWOR and its alternatives at pre-industrial scale”, the incorporation of three new alternative DWORs to evaluate in the laboratory phases and industrial, the publication of the C3.1 deliverable: “Preliminary report on the methodology of cost efficiency and the defined system”, “the advances in the environmental impact model and the basic structure of the web tool of the project.

The most outstanding result of the B1.1 deliverable is the good water and oil repellency shown by the perfluorosilicon products, before and after aging, with a higher yield than the C8 chemistry in some cases. Perfluorosilicones combine repellency to both liquids (water and oils). This chemistry allows the anchoring to the substrate of the fluorocarbon chain via homogenous distribution of the siloxanes. On the contrary, non-fluorinated silicones are very effective applied on non-woven fabrics, but oil repellency is not obtained because their surface energy is higher. The sol-gel technology is also discussed in the report, which is available on the project’s website.
