The specific embodiment
Generally speaking, the predetermined pattern of additional materials can be applied on the base web of wrapping paper, with ignition tendency (" the IP ") characteristic that is improved, and also be improved put out (" SE ") characteristic certainly.Ignition tendency is that it is incorporated herein by reference in full at this according to the described standard testing of carrying out of ASTM E2187-04 " Standard Test Method forMeasuring the Ignition Strength of Smoking articles " (" measuring the standard method of test that smoking article is lighted intensity ").Ignition tendency has been measured smoking article will produce the possibility that enough heat keeps the tobacco rod static combustion when glowing and be positioned on the pad holder thing.Low value IP meets the requirements, and will cause that the minimizing of the possibility of burning takes place following pad holder thing because this value is related to the smoking article that glows.
In addition, the predetermined pattern of additional materials is executed usually and is distributed on the base web, and described base web has and is in about 20CORESTA unit to the interior air permeability of about 80CORESTA unit scope.Additional materials often forms film on base web when doing, film can be local effectively be reduced to air permeability and be in the value of 0CORESTA unit to about 10CORESTA unit scope.In some applications, additional materials is executed cloth as amyloid aqueous solution.
Unexpectedly, find that when patterned base web formed smoking article, some characteristic of starch material can cause predetermined pattern to produce low-down ignition propensity value.Even more surprisingly, have recognized that in the standard specification of some known starch materials, the difference of the material properties of different batches can influence the ignition tendency of resulting smoking article.For instance, commercial by national starch and chemical company (National Starch﹠amp; ChemicalCo.) specification of the oxidized tapioca that provides with Flo-Max 8 shows that pH in 1% solution is in 4.5 to 6.5 the scope, and wherein the molecular weight of particle is greater than 10,000.Surprisingly, when utilizing one batch of pH to be in about 6 Flo-Max 8 to about 6.5 scopes to be applied to predetermined pattern on the base web, find, when with other batch pH less than about 6 but when still being in Flo-Max 8 in the specification of manufacturer and comparing, ignition proclivity has had very big improvement.
Selecting to be used for that film is applied to starch parameter on the wrapping paper, need make various balances or compromise.For example, although HMW starch can cause air permeability effectively to reduce, this HMW starch must use under low concentration, and this causes solution to have quite high water content.But the high water content film extremely is difficult to dry effectively on the porous wrapping paper.In addition, find, the maintenance of the little air bubble of effect of surface tension of starch solution---low surface tension allows that littler bubble is retained in the solution, and high surface tension causes that bubble is coalescent and spins off from solution, and the material of uniformity is used to be applied to wrapping paper thereby produce more.
Although understand fully, believe, compare with more acid (promptly lower pH) starch, the preferred pH scope of oxidized starch show the starch polymer chain than low degree (or more incomplete) thus the more longer polymer chains of oxidation generation.
In addition, longer polymer chain causes solution to have higher viscosity.When in printing process, being applied on the wrapping paper, the starch solution that viscosity the is high more easy more control that will become.
Based on these understanding, find because starch solution has characteristic special and that improve, so that the remarkable improvement of the ignition tendency of patterned wrapping paper.Those characteristics that contain the aqueous solution of oxidized starch comprise: pH is in about 6 to about 6.5 scopes; Surface tension is at least about 6.5 * 10 -2Nm -1(65 dynes per centimeter); Viscosity at ambient temperature is not more than 50mPas; And particle size distribution, for dried particle then be in about 4 microns to about 40 micrometer ranges, and particle in wet about 90% be in about 10 microns to about 100 microns scope.In addition, the molecular weight that preferably has of particle makes solution to have to be in about 20% starch concentration to about 24% scope.Preferably, starch comprises oxidized tapioca.
The aqueous starch solution that is used to be applied on base web or the wrapping paper prepares by following process usually: by at first the water of (promptly under about 15 ℃ to about 25 ℃) under the room temperature of the dried starch powder of required weight and required weight being mixed the starch/that obtains to have predetermined concentration, and make the mixture of starch/water.For example, be 20% starch/in order to prepare predetermined concentration, the starch of 20 parts of weight is mixed with the water of 80 parts of weight.Subsequently, starch/is heated at 90 ℃ of high temperature that are lower than boiling point (promptly being lower than boiling temperature) to about 95 ℃ of scopes.Under this high temperature, kept starch/about 20 minutes to about 30 minutes, so that heat soaking (thermal soaking).Subsequently, make starch/be cooled to room temperature.This cooling step can passively take place, for example, and by abiogenous heat transfer process; Perhaps initiatively (or forcibly) generation of cooling step is for example by being immersed in cooling bath or passing through to adopt the conventional mechanical cooling system.In whole blend step, heating steps, heat soaking step and cooling step, stir starch.Stirring can be continuous or continuous substantially.If other composition (for example calcium carbonate) will be attached in the starch/, then should after returning to room temperature, the starch/that follows the heat soaking step closely add these compositions again.
Can adopt any one technology in numerous printing technologies, the aqueous starch solution that will have afore mentioned rules characteristic and preparation in the above described manner is applied on the base web, for example, described printing technology includes, but are not limited to: intaglio printing, hectographic printing, ink jet printing, spraying and die press print.Other printing process also can be suitable and will be within the instruction of this specification.Yet, preferably, can adopt intaglio printing with starch solution on base web, to obtain patterned wrapping paper.
