Definitions

  • the invention relates to a method for applying a plasticizer to a filter tow strip made of cellulose acetate in the context of the production of hardened feedstocks in the cigarette industry
  • a filter tow strip is continuously withdrawn from a bale.
  • the material is stretched continuously and then sprayed with a plasticizer from a metering device.
  • the filter tow strip is then combined into a fuse, wrapped with paper, glued and cut into filter rods.
  • the filter rod finally hardens to contain its final hardness depending on the amount of plasticizer and type of plasticizer applied. The curing rate also depends on the type of plasticizer.
  • a device suitable for carrying out the above method is described in DE-C-31 22 557.
  • the filter tow strip is sprayed on one side with a plasticizer.
  • a double-sided application of the plasticizer is disclosed in DE-A-28 14 681.
  • plasticizers are currently used.
  • US Pat. No. 3,032,829 describes, in addition to various phthalic acid residues, triethyl citrate and glycerol triacetate (triacetin) as suitable, in each case in concentrations of 2 to 30% by weight, the range from 4 to 15% by weight being preferred.
  • triethylene glycol diacetate is addressed as a suitable plasticizer.
  • Triethylene glycol diacetate cures faster than glycerol triacetate and triethyl citrate
  • the kinetics of the hardening process of the filter material sprayed with plasticizer is becoming increasingly important for the cigarette filter processing industry.
  • triethylene glycol diacetate is rejected for taste reasons and triacetin preferred. It is strictly required that the plasticizer used in each case, and consequently the preferred triacetin, exclude water as far as possible. Therefore, the suppliers always state the water content, which should be less than 0.1% by weight. The maximum value of 0.1% by weight of water in the commercial triacetin guarantees its long-term storage without decomposition. Otherwise, hydrolysis creates acetic acid. In addition to the sensory test, the water content test is the only one that is carried out in the tobacco industry when plasticizers are used.
  • this object is achieved by a method for applying a plasticizer to a filter tow strip made of cellulose acetate in the course of the production of hardened filter rods in the cigarette industry in that a water-containing plasticizer is applied.
  • a water-containing plasticizer can advantageously be used for the stated purpose, the water content preferably being at least about 0.5% by weight and preferably reaching the maximum saturation level .
  • the water content is preferably between about 1 and 4% by weight.
  • advantageous results can still be achieved if saturation of approximately 5% by weight is present and this value is even exceeded, for example more than 6.5%. Separation can occur here.
  • emulsifiers in particular polysorbate and sorbitan esters (Tween ® and clamping ® from ICI) used.
  • the respective plasticizer in particular the commercial triacetin which is preferably used, is stored in a customary large storage container.
  • the plasticizer is drawn off into a separate dosing container, into which water is dosed in the desired amount.
  • this is expediently carried out with vigorous stirring using a high-speed mixer.
  • the water-containing plasticizer is then discharged to act on the filter tow strip at one time or at a time.
  • the two-sided order is considered preferred. Water-containing plasticizers not taken up by the filter tow strip run out of the application system under the action of gravity and are expediently returned to the separate metering container.
  • the system shown here is an advantageous development of the prior art, as described for example in DE-A-28 14 681.
  • the present invention is not subject to any significant restrictions on the manner in which the water-containing plasticizer is applied to the filter tow strip, although the brush application method is preferred.
  • the publications mentioned at the beginning deal in particular with the various order processes.
  • the choice of the temperature range at which the water-containing plasticizer is applied to the filter tow strip is also not critical. When using water-containing triacetin, a temperature range of approximately 30 ° to 60 ° C., in particular 40 ° to 50 ° C., is preferred. In this temperature range there is also an advantageous solubilization of the sprayed filter tow material. Too high a temperature would lead to undesirable effects, for example to the destruction of the preferred triacetin by hydrolysis.Other sizes, such as the stability of the glue used etc , adversely affected
  • water-containing plasticizers in particular water-containing triacetin
  • water-containing triacetin can be used in the process described at the outset, a water content of approximately at least 0.5% by weight having an advantageous effect with regard to the hard kinetics, without causing disturbances Rather, improvements arise in various respects.
  • the moisture content of the filter rod adjusts to the respective equilibrium moisture content of the cellulose acetate-triacetin-water system after final storage, the filter rod produced according to the invention does not differ from traditionally produced ones. They have an identical final hardness.
  • the cigarettes made from these filter rods also show no sensory differences from the known cigarettes.
  • to further accelerate the hard kinetics there is the possibility of storing the process products at elevated temperatures and elevated atmospheric humidity and thus with the indirect entry of moisture. Gentle treatment with microwaves can also follow.
  • a filter tow strip of specification 3, OY35 with a filament titer of 3.33 dtex and a total filter of 38890 dtex was processed on a KDF-AF3 system from Hauni, Hamburg.
  • the tensile resistance of the filter rod was 355 daPa with a filter length of 126 mm and a diameter of 7.8 mm.
  • the above system from the company Hauni, Hamburg is equipped with a double brush spray, similar to that according to DE-A 28 14 681.
  • a product from Henkel with a specified purity of 99.9% was used as the triacetin.

Abstract

L'invention concerne un procédé permettant d'appliquer un plastifiant sur une bande de mèche filtre en acétate de cellulose, dans le cadre de la production de baguettes filtres durcies, dans l'industrie des cigarettes. Selon ledit procédé, on applique un plastifiant contenant de l'eau. Cela permet un durcissement plus rapide du matériau de mèche filtre traité. Comme plastifiant, on utilise, de préférence, de la triacétine.
