Usually it is because of presence of too much hair in the abdomen and around the umbilicus.. those particles gets accumulated in the belly button due to friction between the particle in the cloth and the body hair.. It is not a feature of infection..However if left unremoved, it can cause discharge which could get infected..
Thank you so much for the response. Was worried much about that. But quite relived now.
