Ender 6 stopping mid print

I am new to printing and am having reasonable success, however I recently changed to a pla silk fuscia filament and am having mid print stoppages, I and running 0.4mm tip, 100mm travel, 220 temp, 50 bed, retraction is at 2.0 @ 50 mms. and printing a standard quality. It literally just stops in the middle of the project and when I do a resume it leaves a small knob of material which it then comes around and hits and knocks the component off the bed any ideas ??? Do some Filament brands /colours require different temps?
