Captain reported binding ailerons after takeoff and a decision to immediately return to the departure airport.

Narrative

The First Officer was flying. Once we started our turn he noticed the plane was hard to turn. I took controls and noticed that if you turn the yoke to the right to about the 1 o'clock position there was a noticeable 'catch' or 'binding' in the ailerons. Once I moved the yoke past said catch-point; I release pressure on it. The yoke stayed on the hang up and in a right bank. I had to use moderate force to break the yoke free. I decided to return to the airfield and discontinue the flight. The aircraft was still controllable therefore I did not request priority handling. I gave the controls back to the First Officer until about 700 feet AGL where he said the binding was getting worse. I took controls back; judged that the aircraft; while not having smooth aileron inputs; was able to be landed; and continued the approach. We landed without further issue. Note: The aircraft was in multiple configurations with flaps up/extended and gear up/down. The problem existed still during all configurations. This is a trend item. I had received this aircraft a few months prior in ZZZ where the write up was only 'stiff ailerons' or something relatively similar. I found the crew that had just boarded another aircraft to ask them for specifics. They looked white as ghosts and said they both had to take control of the plane at the same time during their flight. I had refused that aircraft that day. Maintenance said they couldn't find an issue while running their tests on the ground. Both that time and this incident I had been reassigned from the aircraft when they got a rigging kit to arrive. I do not know what they found. I really hope this issue gets identified and resolved.
