Patented Jan. 1, 1952 UNITED STATES PATENT OFFICE CIGARETTE PAPER Robinson E. Matthews, Brevard, N. 0. and Ward D. Harrison, Milford, N. J., assignors to Ecusta Paper Corporation, a porporationof Delaware No Drawing. Application May 16, 1950,

Serial No. 162,402

Our invention relates to cigarette paper and more particularly to improving the ashing properties of cigarette paper when burned as the wrapper on a cigarette.

A desirable paper ash one that has a minimum of carbonized or incompletely burned residue, has a grayish-white color, adheres to the tobacco ash and thereby avoids dropping of ashes on the smokers clothing, but is nevertheless easily fiickable at the will of the smoker. The usual cigarette produces black, curling ashes thatfall from the cigarette onto the smokers clothing.

In accordance with the present invention, we have discovered that markedly improved ashing properties of cigarettes may be obtained by applying to or introducing in the cigarette paper a controlled, small amount of ammonium phosphate, with or without the addition of ammonium sulfate. This efiectsa completely burned, uniform, gray-white ash thatmerges with the tobacco ash and appears as anintegral part thereof. This ash has the desirable prop rty of being easily disintegrated or flicked at the smokers wish, but yet is sufficiently cohesive to prevent accidental falling onto the smckers clothing. Furthermore, it is free of the numerous black curl ng particles that characterize the usual incompletely burned cigarette paper ash.

The ammonium phosphate, which provides the improved as'hing properties characteristic .of ,our invention, may be either ,mono or di-am monium phosphate, or both, and may be applied in aqueous solution. In some cases we have found it advantageous to use ammonium sulfate in conjunction with the ammonium phosphate, in aqueous solution.

The aqueous solution may be applied to the paper by immersion, spraying, coating or sizepress impregnation. For certain commercial applications we have found it advantageous to apply the solution at the size press of the paper machine, to the partially dried paper web. in general, the application may be made at any point on the paper machine. Also, if desired, the solution may be applied to dry or substantially dry paper, either at the end of the drying section of the paper machine or as a separate operation on finished paper. In some instances we have found it advantageous to apply the solu tion to fairly wet paper, or paper containing a substantial moisture content. The moist paper is conducive to more uniform impregnation thereof by the solution and also permits greater concentration of chemicals in the aqueous solution which is applied to the paper, thereby efiecting ec m n dryin We ha e 1 3 113 51 results using a conventional size-press applies. tion of the solution to a running was; thesesrette paper containing beforehand about 50% moisture, and after size-press treatment with the aqueous phosphate solution about moisture,

and then drying the treated paper. I

When the aqueous solution of ammonium phosphate is used alone for addition to thewet paper, the amount of ammonium phosphate, on a dry weight basis, may vary from about 0.1% to expressed as P04. In the usual case the amqunt of ammonium phosphate, on a dry weightbasis, will vary from about 0.2% to about 0.4%, expressed as P04.

When ammonium sulfate is used coniunm tion-with the ammonium phosphate, the amount f mm n m sulfate may va y lf a iabal i 9-; xpr ss d as $04, and a ,tvs calam pe The percentages given hereinaboye for the ammonium ph t wh n used a o e and for t ammonium phosphate and ammonium sulfate ,when used together, provide the desiredashi-ng properties in the cigarette paper hut-do not ,adversely affect the oombustibility of the paper when usedas the wrapperonacigarette.

In commercial practice we have obtained. good results with treating solution containing the following ingredients and proportions:

Ammonium sulfate, 50%, e. g" 1.57 pounds Mono ammonium phosphate, 40%, e. g., 1.26

pounds Di-ammonium phosphate, 10%, e. g., 0.31 pound Water, 50 gallons This aqueous solution, which is practically water clear, will serve to treat, by size-press application, a running moist web of cigarette paper for suflicient time to produce 500 pounds of treated paper having a weight of about 21 grams per square meter of paper.

Substantially equivalent results have been obtained with two other solutions like the above, except in one instance mono ammonium phosphate was the only phosphate used and was present in substantially equal amount with the ammonium sulfate; and in the second instance diammonium phosphate alone was used in like amount.

An aqueous solution containing the ammonium phosphate alone, which we have used with good results, is as follows:

Mono or di-ammonium phosphate pounds l /2 Water gallons-.. 50

A typical product of our invention is cigarette paper made from fiax or other vegetable fiber pulp, and calcium carbonate filler, as basic constituents, and impregnated with the foregoing chemical solution. The carbonate filler may constitute about 20%-30% by weight of the paper.

The finished paper of our invention, when used as a cigarette wrapper, has characteristics that definitely identify it, and show marked improvement over cigarette paper heretofore available. Burning cigarettes using our new paper produce the above-described smooth, uniform, gray-white ash that tucks into the fire zone of the cigarette tobacco ash, adheres to the tobacco ash and thereby prevents the usual accidental falling of ashes on the smokers clothing.

This application is a continuation-in-part of our copending applications Serial Nos. 511,692, filed November 25, 1943, and 711,802, filed November 22, 1946, both being abandoned.

The scope of our invention is indicated in the appended claims.

We claim:

1. A combustible, cellulose, cigarette paper having improved ashing properties when burned as the wrapper on a cigarette and containing throughout, a carbonate filler and ammonium phosphate in an amount of approximately 0.2% to 0.4% phosphate (expressed as P04) which does not adversely affect the combustibility of said cigarette paper wrapper on a cigarette, but upon burning of the cigarette causes the paper to produce a completely burned, uniform, flaky, graywhite, non-falling ash that merges with the tobacco ash and adheres thereto uniformly and continuously throughout the length of the burned cigarette.

2. A combustible, cellulose, cigarette paper having improved ashing properties when burned as the wrapper on a cigarette and containing throughout, a carbonate filler and ammonium phosphate in an amount of approximately 0.2% to 0.4% phosphate (expressed as P04) and 0.0% to 0.32% ammonium sulfate (expressed as $04), which does not adversely affect the combustibility of said cigarette pap-er wrap-per on a cigarette, but upon burning of the cigarette causes the paper to produce a completely burned, uniform, flaky, gray-white, non-falling ash that merges with the tobacco ash and adheres thereto uniformly and continuously throughout the length of the burned cigarette.

3. A combustible, cellulose, cigarette paper wrapper containing throughout the cigarette paper wrapper, a carbonate filler and approximately 0.2% to 0.4% ammonium phosphate (expressed as P04) that causes the wrapper upon burning on the cigarette to produce a grayishwhite, flaky, cohesive ash'throughout the length of the cigarette, which is characteristically free of curling black particles and tends to adhere to the cigarette ash and not fall upon the smokers clothing.

4. A combustible, flax fiber, cigarette paper wrapper containing throughout the wrapper, a carbonate filler and approximately 0.2% to 0.4% ammonium phosphate (expressed as P04) that causes the wrapper upon burning on the cigarette to produce a grayish-white, flaky, cohesive ash throughout the length of the cigarette, which is characteristically free of curling black particles and tends to adhere to the cigarette ash and not fall upon the smokers clothing.

5. A combustible cigarette paper wrap-per consisting of cellulose fibers, carbonate filler, and approximately 0.1% to 1% ammonium phosphate (expressed as P04) that causes the wrapper upon burning on the cigarette to produce a grayish-white, flaky, cohesive ash which is characteristically free of curling, black particles and tends to adhere to the cigarette ash and not fall upon the smokers clothing, said ammonium phosphate alone producing these desirable properties in the cigarette paper ash and yet not retarding the combustibility of the paper or otherwise affecting the igniting properties of the ash on the burning cigarette.

6. A combustible cigarette paper wrapper consisting of cellulose fibers, calcium carbonate filler, and approximately 0.1% to 1% ammonium phosphate (expressed as P04).
