A retraction drops the pressure in the nozzle before the nozzle moves on. Without the retraction the nozzle starts to move while the pressure is still high and it drools until the pressure drops off.
Why no retraction? I don't retract when I print TPU but with PLA and (especially) PETG retraction is pretty much mandatory.

In cura, can you just enable the option Z hop when retracted or mayble play with the combing mode... Hope this helps. Not expert advice lol
