Abstract

Disclosed are articles, such as smoke filters, which contain fibers that have complex geometry in combination with tobacco modify-ing agents such as flavorants. The fibers are preferably made of polyester such as poly(eth-ylene terephthalate) and preferably are cap-able of spontaneously transporting water or n-decane on their surfaces. The articles of the invention result in improved delivery of the to-bacco modifying agent to the user.
