If you were wearing the sweater shown and rubbed your hand on it. You too would gain some negative charge on your hand. Then when you directly touch a metal conductor, like a door knob, you will feel a shock. This is called Conduction. From this scenario, where does the negative charge go when you touch a door knob?

When you touch a metal conductor, like a doorknob, the negative charge that has built up on your hand will flow from your hand to the conductor. This is because metals are conductive materials, which means they allow the flow of electric charges. The excess negative charge leaves your body and disperses into the conductor, equalizing the charge imbalance and producing a shock sensation.
