Problems solved by technology

However, incorporating such components into segmented filters presents technical challenges, such as generating large amounts of dust that can contaminate other filter sections
In addition, such components have limited technical flexibility for incorporation of other active particles, design of unique filter configurations, and removal of large amounts of certain smoke stream components

Embodiment

[0116] In the following examples, the effectiveness of porous materials in removing certain components of cigarette smoke is demonstrated. The porous mass was made from 25% by weight GUR2105 from Ticona, LLC and 75% by weight PICARC 259 (95% activated carbon) from PICA USA, Inc. of Columbus, OH. The porous mass had a percent void system of 72% and an encapsulated pressure drop (EPD) of 2.2 mm water / mm porous mass length. The porous mass has a circumference of approximately 24.5 millimeters. The PICA RC 259 carbon has an average particle size of 569 microns (μ). The porous mass was produced by mixing the resin (GUR 2105) with carbon (PICA RC 259) and then filling a mold with this mixture without applying pressure to the heated mixture (free sintering). Subsequently, the mold was heated to 200° C. for 40 minutes. Subsequently, the porous mass is removed from the mold and allowed to cool. A defined length of porous mass is combined with a sufficient amount of cellulose acetat...

Abstract

Porous masses that comprise a plurality of active particles and binder particles bound together at a plurality of sintered contact points may be useful in filters, including articles (like smoking devices) and methods relating thereto. The production of such filters may involve the production of filter rods that involves forming a desired abutting configuration that comprises a plurality of sections, the plurality of sections comprising at least one porous mass section and at least one other filter section; securing the desired abutting configuration so as to yield a segmented filter rod length; and cutting the segmented filter rod length into segmented filter rods, wherein the steps of forming, securing, and cutting are performed so as to produce the segmented filter rods at a rate of about 25 m / min or greater.

Description

Background of the invention [0001] The present application relates to porous materials for use in filters for smoking devices, and articles and methods related thereto. [0002] The World Health Organization (WHO) has made recommendations to reduce certain components of tobacco smoke. See: WHO Technical Report Series No. 951, The Scientific Basis of Tobacco Product Regulation, World Health Organization (2008). In this paper, WHO recommends, inter alia, to reduce certain components such as acetaldehyde, acrolein, benzene, benzopyrene, 1,3-butadiene and formaldehyde to levels below 125% of the median value of the data set (Ibid., Table 3.10, page 112). In view of new international recommendations on tobacco product regulation, there is a need for new tobacco smoke filters and materials for the manufacture of tobacco smoke filters that can meet these regulations. [0003] The use of carbon-loaded tobacco smoke filters to remove tobacco smoke components is generally limited to ...
