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