He likes to take pieces of paper or clothes and rub them against his head with his paws.
He's marking them with his scent.
A better explanation copy-pasted :
"Why does your cat rub up against you?"
"Cats have scent glands along the tail, on each side of their head, on their lips, base of their tail, chin, near their sex organs, and between their front paws. They use these glands to scent mark their territory. When the cat rubs you, he is marking you with his scent, claiming you as "his." Too, he is picking up your scent. Cats rub up against furniture or doorways for the same reason - to mark the item as "his". (Urine spraying is also a territorial marking, by the way.)"

Maybe he wants all the paper and clothes he can get.
Greedy cat is greedy.
