Abstract
The present disclosure provides an aerosol source member, a substrate portion, and a method of creating a substrate portion for use in an aerosol source member. In an example implementation, a substrate portion of the present disclosure may comprise a series of overlapping layers of a composite substrate sheet, wherein the composite substrate sheet may comprise a non-woven web at least partially formed from regenerated cellulose fibers, a plurality of conductive threads integrated into the non-woven web, and a coating that includes a fibrous material and an aerosol precursor composition.
Claims23
A method of producing a substrate portion for use in an aerosol source member,
- the method comprising:
- providing a series of overlapping layers of a composite substrate sheet, the composite substrate sheet comprising:
- a non-woven web at least partially formed from regenerated cellulose fibers;
- a plurality of conductive threads integrated into the non-woven web;
- and
- a coating that includes a fibrous material and an aerosol precursor composition, integrating the plurality of conductive threads into the non-woven web via tailored fiber placement (TFP), and
- subsequently overlapping the composite substrate sheet into the series of overlapping layers,
- wherein the plurality of conductive threads have an orientation that is perpendicular to a longitudinal direction of the non-woven web.
