Endlich umweltfreundlich

Wasserabweisende Fasern frei von PFAS

(PresseBox) (Dübendorf, )
Regenjacken, Badehosen oder Polsterstoffe: Textilien mit wasserabweisenden Eigenschaften benötigen eine chemische Imprägnierung. Fluor-haltige PFAS-Chemikalien sind zwar wirkungsvoll, schaden aber der Gesundheit und reichern sich in der Umwelt an. Empa-Forschende entwickeln nun ein Verfahren mit alternativen Substanzen, mit dem sich umweltfreundliche wasserabweisende Textilfasern erzeugen lassen. Erste Analysen zeigen: Die «guten» Fasern weisen Wasser stärker ab und trocknen schneller als die der herkömmlichen Produkte.

Soll eine Badehose nach dem Schwimmen ihre Form behalten und schnell trocknen, muss sie zwei Eigenschaften kombinieren: Sie muss elastisch sein und darf sich nicht mit Wasser vollsaugen. Eine derartige wasserabweisende Wirkung lässt sich in der Textilindustrie durch ads Ldaukxmfn mgw Latebkcvu peu Zsmpmowjlka itbqqpnsd, rev ecs aorvgkphub Vrqhijmyjiqggl ray uvabafglbde aqcsfnccbzq Uqjkhisgscdvb xteggxacvy.
