摘要： The present invention addresses the problem of providing: a filter in which a liquid having phenol filtration capability is prevented from leaking out even after prolonged storage; and a flavor inhalation article equipped with said filter. The problem is solved by a filter that is for a flavor inhalation article, and that has a filtering medium including a biodegradable material, and a paper roll wound around the filtering medium. The filtering medium contains a liquid having a phenol filtration capability. A surface of the roll paper where a contact is made with the filtering medium is made of a layer exhibiting liquid-repellent properties with respect to said liquid.

摘要： A biodegradable bi-component fiber may include a polyhydroxyalkanoate and/or polylactic acid with cellulose acetate and/or plasticized cellulose acetate for use in a filter material configured for use in a filter of a smoking article. The bi-component fiber may have a sheath-core construction where one component of the bi-component forms the core, and the other component forms the sheath of each fiber. A filter made in accordance with this design may also include non-biodegradable material.

摘要： Apparatuses, systems, and methods employing ultrasonic bonding to form filter elements for smoking articles are provided. Ultrasonic bonding can be employed to bond the fibers of filter material defining bloomed tow. Use of a plasticizer may not be necessary. Further, filter materials such as polylactic acid, which may not be bonded via a plasticizer, may be employed. However, triacetin or other additional components may be employed to provide the filter element with a desirable sensory attribute in some embodiments. Ultrasonic bonding may be conducted by an ultrasonic bonder that includes an anvil defining a pattern thereon that is selected to define a desired degree of bonding, and thereby a resulting desired firmness and/or pressure drop associated with the filter element.

摘要： Smoking articles including filter elements formed from two or more fibrous inputs with different physical properties are provided. The two or more fibrous inputs are provided in the form of staple fibers, which are at least partially entangled with each other to form a mixed fiber sliver. The mixed fiber sliver includes a first plurality of cellulose acetate staple fibers blended with a second plurality of staple fibers comprising a polymeric material different from the first plurality of staple fibers, such as staple fibers of a degradable polymeric material. The entangled fibers of the mixed fiber sliver may be sufficiently separated from one another such that blooming operations typically required in filter element production may not be necessary prior to incorporating the mixed fiber sliver into a filter element. Related methods, apparatuses and mixed fiber products are also provided by the disclosure.

摘要： The present disclosure provides thermoplastic fibers that comprise homogeneous blends of polylactic acid (PLA) polymers having different degrees of isomeric purity. The fibers exhibit reduced shrinkage and can be formed with increased productivity, specifically in relation to utilizing increased draw ratios. A homogeneous blend can comprise a first PLA polymer and a second PLA polymer, wherein the first PLA polymer has an isomeric purity for the D-isomer or the L-isomer of at least about 99% and the second PLA polymer has an isomeric purity for the D-isomer or the L-isomer of no greater than about 98.5%. The disclosure further encompasses yarns and fabrics formed from the fibers and compositions formed from the yams or fabrics, as well as methods of preparing PLA materials.

摘要： The invention relates to a paper that disintegrates quickly in water, for use as a filter material or filter wrapper paper of a cigarette filter. At least 80 wt % of the paper is formed by cellulose fibers. Of the cellulose fibers, at least 80 wt % are a mixture of long fiber pulp and mercerized pulp. 0 to 90 wt % of the content of the mixture is formed by mercerized pulp, and the rest is formed by long fiber pulp. The cellulose fibers of the mixture have a freeness of at most 30° SR according to ISO 5267. In the disintegration test using an apparatus as described in TAPPI T 261, the paper exhibits a disintegration of at least 60% after 30 seconds.

摘要： A filter material adapted for use as a filter element of a smoking article is provided, the filter material being in the form of a fibrous tow that includes a plurality of filaments of a degradable polyester and a plasticizer composition applied thereto, the plasticizer composition and the degradable polyester having a Relative Energy Difference calculated using Hansen Solubility Parameters of less than about 1.3. Exemplary degradable polyesters include polyglycolic acid, polylactic acid, polyhydroxyalkanoates, polycaprolactone, polybutylene succinate adipate and copolymers or blends thereof. Exemplary plasticizer compositions include one or more of dimethylisosorbide, propylene carbonate, methylbenzyl alcohol, glycerol carbonate acetate, glycerol carbonate ethyl ether, and mixtures thereof, optionally in combination with triacetin. Filter elements and smoking articles, such as cigarettes, that contain the filter material are also provided.
