Production of Filament Yarns Made of PEEK

TL;DRAbstract

This project is a part of European commission collaborative Safeprotex project of Seventh Framework Programme to manufacture high protective clothing for complex emergency operations. The goal of this thesis is to manufacture polyetheretherketone, PEEK, fibers by melt spinning and modify them to provide antimicrobial, self-cleaning and antipollution properties.\nPEEK has excellent thermal and mechanical properties and good chemical resistance. The literature review clearly shows that PEEK should be easily spinnable. Melt spinning is a process where polymer is melted, normally by extruder or piston system. The system of TUT is based on Göttfert capillary rheometer which is a piston system. Melt material is pushed through a small hole after which it faces cold air and starts to cool down. Solidified fiber is drawn to a roll.\nPEEK modification is done by sulfonate groups that change the chemical structure so that functional properties are possible. Without modification the reaction does
