Stain Repellent fluorine-free Car Interior Textiles

The industrial partners of the project have taken decisions to reduce their use of environmentally hazardous perfluorinated substances (PFAS), as a car contains several meters of PFAS-treated textile. The aim is to use environmentally sound silicones in combination with new textile structures to obtain stain repellent car interior textiles. This combination of technologies denotes a new approach to replace PFAS. Realistic alternatives to PFAS will be applied to textiles used in seats, headliners, pillars, sunroofs, sunvisors and parcelshelfs. The process conditions will be optimized in lab and full scale. The surface structure on the fibre, yarn and textile level will be evaluated as a way to enhance the stain repellent effect. Plasma technology will be used as a way to further improve this effect, to reduce the amount of chemicals and to improve the treatment’s resistance to abrasion. A new test method to assess the stain repellency will be developed, along with product prototypes.
