Abstract

A cigarette comprising:
a lighting end (14) and a mouth end (18);
a mouth end piece segment (65) disposed at the mouth end;
an aerosol-generation system disposed between the lighting end and the mouth end piece segment, the aerosol-generation system including
a heat generation segment (35) disposed at the lighting end having a length including a heat source (40) configured to be activated by ignition of the lighting end and an insulation layer (42) of flame-retardant material disposed around the heat source;
an aerosol-generating segment (51) incorporating aerosol-forming material (55), said aerosol-generating segment having a length and being disposed between, but physically separate from, each of the heat generation segment and the mouth end, wherein the aerosol-generating segment includes a substrate comprising
a central core,
a first outer layer (47) of a glycerin-treated fabric, coaxially disposed around the core,
an intermediate layer (48) coaxially disposed around the first outer layer, the intermediate layer including aromatic tobacco paper, and
a second outer layer (49) of a glycerin-treated fabric, coaxially disposed around the intermediate layer, wherein at least a portion of the first, intermediate, and second layers is stitch-bonded together with a substrate heat-conductive material; and
a piece of outer wrapping material (64) oriented to provide an overwrap (i) around the aerosol-generating segment for at least a portion of its length, and (ii) around the heat generation segment for the length of that segment, those segments being connected together by the overwrap to provide a cigarette rod; and
the mouth end piece segment being connected to the cigarette rod using tipping material (78).
