If you only make one cut, it won't stick. The severed fibers will reattach.

The in-universe reasons aren't explained... But we're talking about an anime where a girl is using giant scissors to fight evil clothes, so there's your doyalist answer.

And honestly the why isn't necessary any more than you need to know why you can't just stab a vampire's heart with a dagger, you need a wooden stake.
