Negative.
Rubbing fabric onto a balloon causes an electron buildup on the balloon surface because its material has high insulative properties.
The balloon will gain a negative charge and the woolen sleeve will gain a positive charge.
When you rub a balloon onto your hair or piece of clothing, the balloon collects the electrons (negative charge) from the hair or clothing you rubbed it on. The balloon now has more electrons (negative charge) than protons (positive charge) making it have a negative charge. The hair or clothing has more protons than electrons making it have a positive charge.
One is a negative static charge, the other positive. The exact charge depends on how long and how vigorous the rubbing is. teehee

A rubbed balloon will stick to a wooden wall demonstrating the charge of static electricity. The friction of the rubbing of the balloon causes the charge to build.
The balloon will gain a negative charge and the woolen sleeve will gain a positive charge.

When a balloon is rubbed with a wool cloth, the electrons from the atoms of the wool cloth enter the atoms of the balloon and thus, the number of electrons in the atoms of balloon becomes more than the number of protons. Hence, there is a net negative charge in the balloon, whereas in the wool cloth the number of electrons in its atoms become less than the number of protons, hence there is a net positive charge on the wool cloth.

positive and negative
Benjamin Franklin was the man that defined negative and positive charge. In the nineteenth century, positive and negative charge was known as vitreous and resinous charge, respectively.Franklin defined negative charge as the charge of a piece of amber after being rubbed against glass.
It's due to static electricity build up. The balloons have become charged with electricity and it is the same charge on both balloons (either positive or negative). Opposite charges attract, identical charges repel each other.
The idea is that the balloon gains electric charge.
The wool would have a positive charge, while the comb is negative. This is because the comb will take excess electrons from the wool.
