Abstract:
Disclosed are fibers which contains identification fibers. The identification fibers can contain a plurality of distinct features, or taggants, which vary among the fibers and/or along the length of the identification fibers, a fiber band, or yarn. The disclosed embodiments also relate to the method for making and characterizing the fibers. Characterization of the fibers can include identifying distinct features, combinations of distinct features, and number of fibers with various combinations of distinct features and correlating the distinct features to supply chain information. The supply chain information can be used to track the fibers, fiber band, or yarn from manufacturing through intermediaries, conversion to final product, and/or the consumer.
Abstract:
Disclosed are fibers which contain identification fibers. The identification fibers can comprise one or more chemical markers, or taggants, which may vary among the fibers or be incorporated throughout all of the fibers. The disclosure also relates to the method for making and characterizing the fibers. Characterization of the fibers can include identifying chemical markers and correlating the chemical markers and a taggant chemical marker amounts of at least one of the chemical markers to manufacturer-specific taggants to determine supply chain information. The supply chain information can be used to track the fibers from manufacturing through intermediaries, conversion to final product, and/or the consumer.
Abstract:
The present invention relates to filter material for inclusion in a smoking article, wherein the filter material is in the form of a fibrous tow or a non-woven sheet comprising fine cellulose acetate fibres having a mean diameter of from about 1 μm to about 15 um. The invention also relates to processes for preparing filter material for inclusion in a smoking article, the filter material comprising fine cellulose acetate fibres having a mean diameter of from about 1 μm to about 15 μm. The invention further relates to filters or filter elements comprising the filter material, smoking articles comprising the same, and use of the filter material in smoke filtration.
Abstract:
The invention relates to a filter (1) for a smoking article, a method of production thereof, a smoking article and a device for inserting a first fibrous filter material (3) into a second fibrous filter material (4) to form a filter for a smoking article. Particularly but not exclusively the invention relates to a smoking article filter segment including a region of first fibrous filter material (3) disposed within a region of second fibrous filter material (4) and a method of production thereof. The first fibrous filter material (3) in some embodiments comprises greater than 5% by volume of the total filter segment volume and in some embodiments the first fibrous material comprises PLA fibres and the second fibrous filter material comprises CA fibres.
Abstract:
A filter (14) for a smoking article (10) comprises a segment of filtration material (16), the filtration material (16) comprising randomly oriented regenerated cellulose fibres and cellulose acetate fibers. The filtration material (16) further comprises triacetin. The filter (14) also includes a wrapper (18) circumscribing the segment of filtration material (16).
Abstract:
The invention relates to a filter for a smoking article, a method of production thereof, a smoking article and a device for inserting a first fibrous filter material into a second fibrous filter material to form a filter for a smoking article. Particularly but not exclusively the invention relates to a smoking article filter segment including a region of first fibrous filter material disposed within a region of second fibrous filter material and a method of production thereof. The first fibrous filter material in some embodiments comprises greater than 10% by volume of the total filter segment volume and in some embodiments the first fibrous material comprises PLA fibres and the second fibrous filter material comprises CA fibres.
Abstract:
The present invention relates to improvements in filters for use in smoking articles such as cigarettes, cigars and cigarillos. The improvements, particularly but not exclusively, relate to filter capabilities and to the manufacture of such filters. In some examples, a filter for a smoking article is described having randomly orientated short-length fibres formed into a shape other than a cylinder or formed into a cylinder having a circumference smaller than 16mm or a circumference greater than 25mm. The application also describes a filter for a smoking article comprising various other filter arrangements including absorbent and/or adsorbent materials.
Abstract:
The present invention relates to improvements in filters, for use in smoking articles, comprising randomly oriented discrete fibres, wherein a loss of particulate additives can be reduced by adding a liquid with a viscosity of at least 2000 m Pa*s at 20° C and normal pressure.
Abstract:
Disclosed are fibers which contain identification fibers. The identification fibers can contain a one or more of chemical markers and one or more distinct features, or taggants, which may vary among the fibers or be incorporated throughout all of the fibers. The chemical markers and distinct features can be representative of specific supply chain information. The supply chain information can be used to track the fibers from manufacturing through intermediaries, conversion to final product, and/or the consumer. The disclosed embodiments also relate to the method for making and characterizing the fibers. Characterization of the fibers can include identifying chemical markers and distinct features and correlating the chemical markers and distinct features to manufacturer-specific taggants to determine supply chain information.
Abstract:
The present invention relates to filter material for inclusion in a smoking article, said filter material comprising a base material comprising or made from fibres having a first diameter or mean diameter, and fine fibres having a diameter or mean diameter which is smaller than the first diameter, wherein the filter material comprises more than 10% by weight and/or by volume fine fibres or wherein the diameter or mean diameter of the fine fibres is between about 1.0 µm and about 1.5 µm. The invention also relates to filters or filter elements comprising the filter material, smoking articles comprising the same, and use of the filter material in smoke filtration.
