- Figure 10 is a perspective of -a short length of the fibrous element after it has been discharged from the reshaping device.
- my method for forming the fibrous vabsorbent element comprises thesteps of first forming a sliver or bundle of a mixture of non-adhesive fibers and potentially adhesive fibers.
- the formed sliver is then passed through an activating chamber wherein the potentially adhesive fibers are activated to an adhesive condition.
- the sliver is. compressed as it is discharged from the activating chamber wherebyxthe fibers are bonded together.
- the sliver is then collected in a coiled :package on a .wind-up spool or other suitable wind-up element during It will be understood that throughout'the following specification and claims, the terms non-adhesive and potentially adhesive refer to'types of fibers,,one of,
- the non-adhesive fiber will not be thermoplastic-but a thermoplastic fiber could be used provided the temperature atI-which it became tacky is sufliciently higher than the temperature at which the other potentially adhesive fiberbecom'es tacky.
- the potentially adhesive fibers are 'formed from vinyl resins resulting from the polymerization of compounds containing the'vinyl group such as polyvinylchloride or copolymers of vinyl chloride and vinyl acetate.
- FIG. 1 shows staple, and potentially adhesive or thermoplastic fibers.
- the fibers mentioned above are of the textile fiber the fibrous element'in bundle or sliver form.
- the sliver A is a carefully blended mixture of non-adhesive regenerated cellulose fibers, suchas rayon class having diameters of at least 9 microns.
- the mixture of the present invention can .be. satisfactorily formed .by uniformly distributing 10-25% of the potentially adhesive fibers into the major proportion,
- the potentially adhesive fibers should comprise at least 10% by Weight of the mixture and preferably should be in the range off20% by weight]
- the length. of the individual fibers may vary from to 2 /2 inches and should be between 1 to 2 /2 denier, preferably 1 to 1 /2 denier. Due to the crimp in the non-adhesive fibers and, if desired,'in the potentially adhesive fibers, minute traps or voids are formed within the body of the element which enhance the absorptiveness of the element and also provide for the porosity which in turn permits easy draw.
- the fibers specified above range in weight from 100- 125 grains and the fine relatively short length fibers provide a compact, dense structure in which many of the shorter length fibers will be across the' general longitudinal axis of the element.
- nonadhesive or rayon fibers within the fibrous mass are crimped.
- the fibers' may be crimped chemically as distinguished from a mechanical crimp.
- Such chemical crimping is disclosed and claimed in United States Patent 2,517,694. This crimping remains in the fiber even when it is wet.
- the filaments may be mechanically crimped according to well known processes and apparatus. Since relatively small denier fibers are used to form the element and since the fibers are crimped, numerous minute traps or voids are formed within the element which render the fibrous element capable of entrapping and retaining liquids, moisture and minute solid particles.
- the potentially adhesive fibers may or may not be crimped.
- the potentially adhesive fibers are activated, as will be explained hereinafter, to autogenously bond together the non-adhesive fibers in the sliver A.
- the fibers are compressed, as will also be explained, after the potentially adhesive fibers have been activated to provide a compact article of good strength.
- a tobacco smoke filter'or plug B formed from the fibrous mass or sliver A of Figure l is shown in Figure 2 of the drawing.
- the tobacco smokefilter B in this instance, is of cylindrical shape.
- the potentially adhesive fibers have been activated and compressed to autogenously bond together the non-adhesive rayon fibers and the potentially adhesive fibers to provide a compact cylindrical shaped article of good strength.
- the completed element is to be used as a cigarette filter, the bonded element is wrapped or stuffed in a paper wrapper 2 and cut into suitable lengths to form the filter plug B.
- Figure 3 shows the wrapped filter plug'B of . Figure 2 incorporated in a cigarette C.
- the tobacco -and the filter plug B are formed into a unitary cigarette having the usual cigarette paper 11.
- the apparatus'in which the relatively loose sliver isactivated and transformed into a comparatively strong, dense but porous rod comprises a chamber18 into which the sliver 19'is drawn through a funnel shaped die 20 mounted in the forward end wall 21 of the chamber.
- the tacky sliver is drawn out of the chamber 18 through a relatively longer die 23 mounted in the rear wall 24 of the chamber in alignment with die 20.
- Die 23 has a substantially smaller bore than entrance die 20.
- the preferred diameters for the entrance and exit dies are threequarters and three-eighths of an inch respectively when it is desired to fabricate a cigarette filter. For other articles the dimension of the bores may be changed but substantially the same ratio should be maintained.
- the inside ofthe chamber 18 is maintained at an elevated temperature of approximately 180 C.
- heating elements 25 are covered by suitable insulating material 27 through which electrical connections to the heaters may be made at 28, 28.
- suitable insulating material 27 At a point approximately midway between the downstream terminus of die 20' and the upstream terminus of die 23, a liquid-softening or activatingagent such as acetone is introduced in drop.forrn'"into thel charn' ber through a nozzle 30. Theacetone is vaporized when it falls onto the heated chamber wall.
- the potentially adhesive fibers in the sliver As the vapor contacts the potentially adhesive fibers in the sliver, they become sufficiently soft throughout the sliver so that when the sliver is drawn through die 23 there is a compression or rearrangement of the structure to provide a firm, compact, internally bound but porous rod 31.
- they are preferably made of polytetrafluoroethylene, sold commercially under the trade name of Teflon.
- Vaporized acetone as an activating agent for the potentially adhesive fibers is preferred in that it has been found that the fibers within the sliver 19 which have been subjected to vaporized acetoneare more firmly bonded together and the finished filter .plug exhibits greater stiffness and excellent draw properties which features also contribute to the success of the filter. .It has also been found that thecleaner cuts may be made with the acetone activated filter plug.
- the softening of the potentially adhesive fibers is achieved primarily by means of the solvent, namely, acetone, which is applied to the fibers. However, it will be understood that the temperature in chamber 18 may be sufiiciently'elevated to assist or, if desired, completely provide for the softening of the minor proportion fibers.
- a continuous filter rod 31 is collected in wound package form on a suitable wind-up spool 70 immediately after it has set up after being discharged from the chamber 18.
- the filter rod 31 is wound up in package form by the filter producer and while it is shipped to the cigarettee manufacturer/the original shape of the rod 31 is deformed into a flattened or otherwise distorted condition because of the tension applied during the windingoperation and because of the compressive force applied by the outer coils of la ers of the rod upon the inner coils of layers of the rod.
- Figure 7 shows a reshaping device which may be used by the cigarette manufacturer to restore the continuous flattened rod 31 to its original cylindrical shape.
- the continuous filter rod 31 is unwound from its coiled package formed on the wind-upspool 70 and is fed into the reshaping device 72.
- the reshaping device 72 comprises an enclosedchamber 74 into which a moist heated fluid medium such as steam is introduced throughjinlet 76.
- the continuous ro d31 is fed into the chamber through an entrance die 78 which extends through an end wal1 80 of the reshaping device 72.
- the rod passes through a shaping dieSZ which. extends through the opposite wall of the shaping device 72.
- the shaping die 82 has a bore of cylindrical shape.
- Figure 9 shows the flattened condition of the filter rod 31 before it is introduced into the reshaping device 72 while Figure 10 shows the rod 31 restored to its original cylindrical shape after it has been discharged from the reshaping device 72.
- the heat from the steam softens the potentially adhesive fibers in the rod 31 while the moisture softens the nonadhesive fibers within the rod 31.
- the rod 31 is easily reshaped to its original cylindrical form as it passes through the shaping die 82.
- the reshaping device 72 is retained by the cigarette manufacturer whereupon when the manufacturer is ready to incorporate the filter rod 31 with the tobacco cylinders to make filter cigarettes, he merely has to unwind the rod from its package form and pass it through the reshaping device 72. As the rod 31 is discharged from the reshaping device, it is fed directly into a filter wrapping apparatus (not shown) wherein a paper wrapper is secured around the rod 31.
- the cigarettee manufacturer need not clutter up his available space with apparatus for producing the filter material. This time, energy and available space may therefore be devoted entirely to the production of cigarettes.
- the outside filter material producer need not be concerned about the flattened condition of the filter rod in its packaged form since he knows that it can easily be restored to its original cylindrical shape by the cigarette manufacturer. 7
- the method of producing a relatively stiif fibrous rod of circular cross-section suitable for use as a cigarette filter comprising forming a sliver of a mixture of nonadhesive and potentially adhesive fibers, passing the sliver through a chamber, activating the potentially adhesive fibers within the chamber with a vaporized activating agent, passing the sliver through a circular die to compress the fibers and form a fibrous cylinder of circular cross-section, permitting the activating agent to volatilize whereby a relatively stiff fibrous rod of circular crosssection results, winding the fibrous rod into a coil whereby the cross-section thereof is distorted, unwinding the rod and subjecting it to the action of steam to soften the fibers, drawing the rod while the fibers are in a softened condition through a circular die of substantially the same diameter as the previously mentioned die to restore the rod to the dimensions it had before being wound into a coil.
- non-adhesive fibers are crimped viscose rayon and the potentially adhesive fibers are formed of a copolyrner of vinyl chloride and vinyl acetate.
