If an acetate strip is rubbed with a paper towel, what charges do the two products obtain?

If the acetate strip is rubbed with the paper towel, electrons will move from the paper towel onto the acetate strip. The acetate strip will now have more negative charges than positive. The paper towel, which lost the electrons, will have more positive charges than negative charges. The result is that the acetate strip is charged negatively and the paper towel is charged positively.
