In books that discuss cotton spinning, we're told that one end of cotton sliver will spin more smoothly than the other due to the direction of carding. So if your cotton is not spinning smoothly, flip the cotton sliver over to see if it spins more smoothly from the other end.
Wool roving can also be directional -- not always, but sometimes, depending on the carding equipment. The thing with wool roving is that it usually contains jumbled fibers anyway, so the texture from spinning it can be attributed to the jumble as much as the carding direction – so it’s not usually much of a concern. I learned about direction in roving from a very experienced friend of mine (Joan, the lady behind Crosspatch Creations), who sends much of her wool off to a mill to be carded, and has found that she can get a more even yarn when spinning from the “right” end of the roving. She also told me that directionality in roving is not always present, that it does depend a fair bit on the carding machine.
How can you tell which end might be better to spin from? Without spinning, run your fingers gently along the surface of the roving in each direction; one should feel smoother than the other – start from the end you started the rub, in the smoother direction.
When spinning, if the drafting feels start-and-stoppy, try spinning from the other end, to see if it is smoother.
Not all roving will seem to have a direction – it depends on the machinery it was carded on, some tend to impart more direction than others. The wool/fibers involved may also affect it (what they are, how jumbled they are, how carded they are) So if it feels the same both ways, dive in, and see how it spins.
I have not read anything about commercial top having a smoother direction, but I wouldn't be surprised if it, too, was occasionally directional. If you try it, I'd be interested to hear what you find.
