Definitions

  • Water soluble polysaccharide derivatives have become established in the art as particularly useful film forming adhesives for the manufacture of tobacco products from finely divided tobacco. in general these polysaccharides ture of all of the foregoing smoking products as well as other shaped articles such as pipe cartridges and the like.
  • polysaccharide gums used either individually or admixed with one another in any proportion, comprise about 1% to 30% of the finished tobacco product and preferably between 5% and 15% by weight.
  • the tobacco used in the manufacture of the products of the present invention is preferably dry ground and will pass through screens having mesh openings between about 0.8 millimeters and about 0103 millimeters or less.
  • Wet ground tobacco such as colloidal tobacco or beaten tobacco fibers, may also be used separately or together with the dry ground tobacco. It is preferable to use at least a major proportion of dry ground tobacco which may be prepared in a hammer mill, for example.
  • reinforcing tape When reinforcing tape, to be used at the mouthpiece of cigars and cigarettes, is made according to this invention, it should contain at least 25% by weight of tobacco and preferably above In most other tobacco products including chewing tobacco, pipe tobacco, cigarette and cigar filler shreads, cigar binder and wrapper, the tobacco should constitute a major proportion by weight of the finished manufacture.
  • This invention is useful in the manufacmonia and related products when tobacco is stored under conditions of insufficient ventilation of the individual surfaces of the smoking products. It is possible to mitigate some of these undesirable effects by refrigeration and ventilation used either separately or together but heretofore no wet strength ingredient for combination with water soluble polysaccharides has been available which effectively resists this loss of moisture resistance with all kinds of tobacco. It is to be noted that some kinds of natural leaf "tobacco have generally more pronounced adverse storage effects upon moisture resistance of dialdehyde cross-linked polysaccharides than do other species of tobacco.
  • moisture resistance agents are included in the tobacco product on the basis of the polysaccharide gum content and in general range from about 5% to about 501% by weight of the gum and preferably about one-fourth of the gum weight.
  • the formaldehyde derivatives of this invention may be used either mixed together, separately, or mixed with conventional dialdehyde crosslinking agents such as glyoxal and dialdehyde starch.
  • the proportions of mixing the materials with one anotheror With the dialdehyde materials . are determined by the use to which the tobacco product is put and by the character and species of the particular adhesive and tobacco used.
  • a relatively larger proportion of formaldehyde material should be added to the polysaccharide.
  • more moisture resistance material may be added to mouthpiece reinforcement tape since great moisture resistance with little concern for burn aroma is required.
  • FIGURE 1 shows a schematic formula for urea.
  • FIGURE 2 shows a schematic formula for melamine.
  • FIGURE 3 shows a schematic formula for trimethylol melamine.
  • FIGURE 4 shows a schematic formula for the trimethyl ether of'trimethylol melamine, a preferred form of the invention.
  • Each of the carbons on the ring of FIGURE 4 is bonded to a branch nitrogen which in turn has substituted a hydrogen and ether chain.
  • Each of the hydrogens bonded to these nitrogens may be further substituted by a lower alkyl ether of a methylol group to form various alternative products useful with different tobaccos for enhancing moisture resistance.
  • FIGURE 5 illustrates a schematic formula of dimethylol urea, another valuable moisture resistance agent.
  • FIGURE 6 is a schematic formula for formaldehyde.
  • the tobacco compositions of the present invention also include additional conventional additives such as humec tants, for example glycerine and glycols; moisture, about 20%; diatomaceous earth, clay and other ash additives; fibers and pulp, such as paper pulp or tobacco stem pulp to give mechanical coherence; fungicides and fungistats; coloring agents and dyes; and caseing solutions and flavors such as menthol and aromatic substances which may be used for example in pipe tobacco.
  • additional conventional additives such as humec tants, for example glycerine and glycols
  • moisture about 20%
  • diatomaceous earth, clay and other ash additives such as paper pulp or tobacco stem pulp to give mechanical coherence
  • fungicides and fungistats such as paper pulp or tobacco stem pulp to give mechanical coherence
  • coloring agents and dyes such as menthol and aromatic substances which may be used for example in pipe tobacco.
  • finely divided tobacco with an aqueous mixture of one i or more water soluble polysaccharides together with any of the above ingredients and a moisture resistance agent If a thick paste is formed this may be suitably shaped, for example, into a film, or shred and dried completely and remoistened to an appropriate moisture content such as or by weight. Moisture content of the finished product may range from 10% to 50% by weight. It has been found that the action of heat in drying tends to activate the moisture resistance agent so that once the product has been dried it acquires moisture resistance. It may afterward be remoistened. In general it is desirable to shape and dry the product promptly after the composition is compounded to obtain the maximum moisture resistance.
  • the acid catalyst is not generally an essential ingredient but is a useful adjunct to the formaldehyde Wet strength agents of this invention.
  • the preferred acid for use with this invention is a 10% aqueous solution of phosphoric acid. Volatile hydrocloric acid solutions may be used separately or together with phosphoric acid.
  • Example I In a preferred example of this invention one kilogram of guar gum powder is dispersed in forty-nine kilograms of water to form a viscous solution. To this is added 500 grams of a 10% aqueous phosphoric acid solution. If the phosphoric acid solution is omitted it is necessary to dry the product at a temperature between 110 C. and 150 C., rather than 100 C. To this mixture is added two kilograms of a 10% clear aqueous solution of the trimethyl ether of trimethylol melamine. This product is generally available as an 80% clear aqueous solution and is preferably diluted to the 10% range for use in formulation.
  • Example I In another example of the invention one kilogram of hydroxyethyl cellulose powder is dispersed in forty-nine kilograms of Water and is mixed with two kilograms of a 10% aqueous solution of dimethylol urea. Dimethylol urea is ordinarily supplied as a solid powder which can be first formed into a 10% by weight aqueous solution by mild heating. Finally two kilograms of cigarette tobacco dust are sifted or blown over the surface'of a thin film of the above liquid material so that all of the tobacco particles are imbedded in the surface of the film and the film is dried over steam.
  • the tobacco compositions of Examples 1 and Il may be formed in conventional Ways, such as shredding, extruding and the like, into useful tobacco products and may be incorporated in any proportion with natural whole leaf tobacco such as in the blend of a cigarette filler.
  • a composition of matter comprising at least 25% by weight of finely divided tobacco adhered together by an adhesive composition, said adhesive composition comprising a mixture of a major proportion by weight of a polysaccharide and a minor proportion by weight of a moisture resistance agent, said agent being selected from the group consisting of melamine formaldehydes, urea formaldehydes and the lower alkyl ethers of said urea and melamine formaldehydes.
  • a shaped smoking article made from the composition of claim 1.
  • composition according to claim 1 in which the agent is the trimethyl ether of trimethylol melamine.
  • composition according to claim 1 in which the agent is dimethylol urea.
  • a method of tobacco manufacture which comprises: (1) forming an aqueous mixture of a polysaccharide adhesive and a moisture resistance agent, said agent being selected from the group consisting of melamine formaldehydes, urea formaldehydes and the lower alkyl ethers of said urea and melamine formaldehydes; (2) con-tacting said aqueous mixture with a quantity of finely divided tobacco greater than one-half the dry weight of said mixture to form an aqueous tobacco composition; and (3) adjusting the moisture content of and drying said composition to about 10% to 50% moisture by weight.
  • a method according to claim 7 in which phosphoric acid is added to said mixture prior to drying, to reduce the duration and heat of drying.
