Description

201200042 VI. Description of the Invention: [Technical Field of Invention] The present invention relates to a cigarette filter particularly for cigarettes. [Prior Art] Cigarette filters can be made from many different materials. Most commercial cigarette filters are made of cellulose acetate. Other filter media' such as paper' nonwoven webs made from fiber tows such as natural and/or synthetic fibers (e.g., polypropylene) are used only to a limited extent. Paper filters have many advantages over cellulose acetate, especially in terms of cost reduction, improved particle removal efficiency at the same pressure drop, higher adsorption capacity such as peppermint, faster bio-differentiation and smoking. Less tendency to collapse. However, paper filters have many disadvantages compared to cellulose acetate, such as poor end appearance and unacceptable taste. The disadvantages mentioned above make the paper filter unusable for a wide range of commercial uses. Further restrictions on paper filters are found in the volatile and semi-volatile stages of cigarette smoke compared to cellulose acetate, such as the retention of toxic phenolic compounds such as phenol, cresol, catechol and resorcinol. This will result in a higher relative yield of phenolic compounds in cigarette paper filters. This is known as the selectivity of the cellulose acetate filter for phenolic compounds, rather than by any congenital deficiency of the paper filter. However, of course, it is also necessary to strengthen the paper to maintain the mouth, so that the smoker will not be exposed to a higher degree of compound than the cellulose acetate when smoking the paper filter cigarette. The first aspect of the invention provides a cigarette filter or filter 201200042. The component comprises (as formed by) a continuous web comprising (as formed of a material comprising the following) a second filter material, and a sputum selection & other filter material; wherein the first filter material comprises a bundle of cellulose acetate 4, which has a total Danny of 44,000 or less, and from 2.1 to 8.3 (eg 2.1) 6.3 or 6.5 to 83, such as 2 to 6 3, for example, from 3 to 6.2) filament fiber denier; and the second filter comprises paper. The filter or nozzle element can be (or include) a rod that includes (as formed by) a continuous web. The first filter medium comprises cellulose acetate tow, and the second filter material comprises: as can be seen from Figure 3, the continuous web comprising the first and second filter materials: the end of the filter is compared to a single paper filter Mouth, with a large Tiejia #幸乂佳's end appearance, this is because the first filter material (cellulose acetate tow) tends to fill the usual single paper filter (see the conventional single paper basket shown in Figure 2) Mouth) A small passage of associated origami. The teardrop or over-it element of the present invention provides a satisfactory end appearance, efficient production and cost, and an effective combination. Applicants have surprisingly discovered that the filter or filter element of the present invention can also provide significant selectivity to the compound (e.g., phenol and/or phenol) from cigarette smoke. It is well known that tars including cellulose acetate and paper filters and sturdy components maintain (iv) the ratio of cellulose acetate to paper in the mouth is proportional to 'and that the retention of phenolic compounds is expected to follow a similar trend. Applicants have found that cellulose acetate tows in which paper is used in a continuous roll of paper have specific characteristics (and/or a specific amount of acid-sensitive cellulose tow and paper in the straight).

Any filter or filter cigarette according to the present invention may not be ventilated, or by the art Well known methods of venting, such as by using a plug wrap, and/or a plug wrap (4) a laser perforation of a gold bag I. 4: According to another aspect of the present invention, there is provided a 匕3 tobacco according to the present invention. Filter cigarette of cigarette filter or filter element. '10-g. .201200042 The filter or filter element according to the invention can be made as a continuous rod (as described above). The continuous rod is continuously sent out from the exit of the production machine. Cut into finite lengths for subsequent use. Such cuts can be divided into individual spouts or filter elements as defined and described above, each of which is then attached to a separately packaged straw-forming filter cigarette. However, It is common for rods that are continuously fed to be first cut into double or higher multiples (usually four or six times) for subsequent use; when the initial cut is divided into four or more lengths, the latter is then cut into double lengths. Used for filter cigarette group The double length filter rod is assembled and joined between a pair of packaged tobacco (by ring tip or full bronzing package) by a combination of two separate filter cigarettes in the center. The invention includes double and More times the length of the filter rod (and/or the filter element rod). The term fiber denier is well known in the art and represents the weight per unit length (linear density) of a continuous filament or yarn. Danny represents the weight of the material of 9 km (9000 m) long. Therefore, the lower the fiber Dani number, the finer the material; the higher the fiber Dani number, the coarser the material. The invention will now be described with reference to the accompanying drawings. [Embodiment] Fig. 1 shows a schematic side view of a device for forming a filter 'nozzle or a device according to the present invention. The first filter-winding-guide (7) enters two sets of rollers (3, 3a, 4(,) : aJ^ Included... 3.8Y37 vinegar brewed cellulose tow _ acid fiber = silk [as is well known in the art, filament fiber Danny / filament shape," Danny 0 〇 _), therefore, 3.8 Υ 37 It has 3 8 filament fibers: a fiber Y-shaped cross section and 37,000 total fiber denier. This Danny's fruit is well known and easy to purchase 5 -11- 201200042. The drum (4, 4a) rotates more rapidly than the drum (3, 3a), which causes the tow to be opened by the elongated dragon to form a first web having a roll width of about $25 mm. The tow web then enters the spray booth (5) where it is sprayed with triacetin before exiting the spray booth via a set of conveyor rollers (6, 6a). These operations are well known in the manufacture of cellulose acetate filters. A roll of second filter material in the form of paper (7) suitable for the manufacture of a cigarette tip (36 g/m2 paper supplied by Swiss QuaHty papef) (4) The unwinding is simultaneously carried out at the same speed in the same direction as the linear direction, and the pressure loss portion of the pair of rolls (9, 9a) is fed into the first filter material (tow) which is sprayed. The roll of cellulose acetate tow (first tear material) and the roll paper (second filter) are thus face-aligned (one side of the roll of cellulose acetate tow faces one side of the roll paper) 'because they pass through the pair a cooling section between the rolls (9, 9a). The s-rolling pros (9 ' 9 a) have specific groove patterns and are similar to those typically used for embossing filter paper so that they can subsequently form a cylindrical rod (although the use of rolls (9 ' 9a) in the cellulose acetate filter The processing is not normal) and the lateral or substantially transverse path of the paper (7) roll and the tow roll is positioned. The rolls (9, 9a) are combined and compressed/embossed under sufficient nip and rolled into a continuous web of paper and cellulose acetate tow, and then made into a conventional filter for conversion to a cigarette filter rod. The accessories of the machine (not shown) are configured. The filter package of the breathable paper can be applied around the filter rod by conventional means. In an example of the invention, ("Sample B", see Example 1 and Table 1 below), the apparatus of Figure 1 is used to produce a filter rod (and filter) that is 90 mm wide supplied by Swiss quality paper. 36 grams of paper and 3.8Y37 cellulose acetate tow.
