Woollen or synthetic sweaters develop static charges (electrons) on them due to friction. While taking off our sweater, these charges move in streams between the sweater and our body, i.e. electric discharge takes place.  This results in crackling sound and miniature sparks of lightning.

Sometimes a crackling sound is heard while taking off sweater during winters because the woollen sweater gets charged because of the friction between the sweater and the body.
