Abstract: An apparatus for forming a polycomponent fibre having a first, fibre forming component comprising a polymer, and a second, component comprising an active ingredient that will selectively reduce or remove components of tobacco smoke. The apparatus has a first reservoir for containing the first component, and a second reservoir for containing the dispersion, second solution or liquid. The dispersion, second solution or liquid includes the second component. The apparatus also has a polycomponent spinnerette adapted to coextrude the first component and the second component to form the polycomponent fibre. The apparatus also includes a first conduit for connecting the first reservoir to the spinnerette, and a second conduit for connecting the second reservoir to the spinnerette.

Abstract: A method for forming a polycomponent fiber comprising a first, fiber-forming component comprising a polymer, and a second, component comprising an active ingredient that will selectively reduce or remove components of tobacco smoke, the method comprising the steps of: i. forming a dispersion, second solution or liquid comprising the second component; and ii. coextruding the first component and the dispersion, second solution or liquid through a jet or aperture to form a fiber comprising a first portion formed from the first component, and a second portion formed from the second component.
