Abstract [sv]

Om människor fortsätter med det konsumtionsbeteende som råder idag kommer jor-den resurser ta slut. Den fossila råvaran petroleum används vanligtvis vid framställ-ning av polyester och polyamid. Petroleum har en 100 000 årlig process, vilket är en ofantlig skillnad i förhållande till den takt som det förbrukas. Därför har eventuella möjligheter att återskapa en ny filament av återvunnet syntetiskt blandmaterial un-dersökts i detta arbete.

Det finns befintliga metoder för att återvinna polyester och polyamid som homogena material. Dock vid återvinning i en gemensam process av materialen får den slutliga produkten en försämrad kvalité. Mekanisk och kemisk återvinning fungerar för att framställa syntetiska filament men i dagsläget kan endast den kemiska ge likvärdig kvalité på det återvunna filamentet i förhållande till den jungfruliga.

Det har hittats ett flertal separationsmetoder som antas kunna tillämpas till bland-materialet. Olika egenskaper såsom densitet, polaritet och laddningsmöjligheter kan utnyttjas för att separera polymererna. Polyester och polyamid antas kunna separe-ras, dock görs inte detta på industriell basis troligtvis på grund av kvantitet, resurser och pris.

Abstract [en]

If people continue with the present consumption behaviour, the earth´s resources will run out. The fossil raw material petroleum is normally used in the manufacture of polyester and polyamide. Petroleum has a 100 000 annual process, which is a huge difference compared to the rate at which it is consumed. Therefore, any opportunities to recreate a new fibre from recycled synthetic bland materials are studied in this work.

There are existing methods to recycle polyester and polyamide as homogeneous ma-terials. However, the recovery in a joint process get the final product a degraded quality. Mechanical and chemical recycling makes it possible to produce new syn-thetic filaments, but in the current situation, the chemical will provide comparable quality of the recycled filament in relation to the virgin.

Several separation methods can be applied to the blend material. Various properties such as density, polarity and charging possibilities can be used to separate polymers. Polyester and polyamide are assumed to be separated, however, is not done on an industrial basis, probably because of the quantity, resources and money.
