Definitions
- the present invention relates to a formulation for use as a lubricant in the manufacture of threads.
- the threads are first produced by a spinning process, which is preferably the solvent spinning process, and then further processed as a lubricant while applying the formulation according to the invention to the surface of the threads.
- the threads produced are preferably cellulose acetate threads and these threads are used for the manufacture of filters for tobacco products, especially cigarette filters.
- the patent specification GB 896,599 describes tobacco filters which can be used in cigarettes, pipes, cigarette holders or cigar holders.
- the filter elements described consist of bundles of continuous synthetic filaments, water-insoluble calcium or magnesium salts being present in finely divided form on the surface of the filaments. These finely divided particles are fixed on the fibers by oils.
- these oils can also be high-boiling liquid esters of native origin, liquid esters of natural fats or liquid high-molecular fatty alcohols. 0
- the patent specification GB 765,962 describes a tobacco filter element which consists of cellulose acetate fibers.
- the cellulose acetate filter material is subjected to various processing steps, such as, for example, stretching and crimping the fibers.
- processing steps such as, for example, stretching and crimping the fibers.
- an electrostatic charging of the fibers must be prevented on the one hand and on the other hand the surface of the fiber must be provided with a lubricant so that the fiber can be subjected to these processing steps.
- a lubricant contains an o mineral oil with a purity with which it would also be suitable for the manufacture of pharmaceutical products.
- DE 12 12 459 describes a stiff tobacco smoke filter which consists of a bundle of optionally crimped continuous threads and a paper wrapper.
- the threads consist of a mixture of a polyalphaolefin and a plasticizer-soluble polymer of an organic plasticizer.
- liquid high-boiling organic esters or water-insoluble propylene glycols or polybutylene glycols can also be used as the liquid organic plasticizer.
- U.S. Patent 4,330,422 describes a cleaning composition containing white mineral oil.
- the emulsion is used to treat and clean metal surfaces.
- the emulsion of the invention contains 20-50% by weight of a mineral oil with a viscosity of 50-380 Saybolt seconds, measured at 100 ° F and 0.5 to 10% by weight of an emulsifier.
- a mineral oil with a viscosity of 50-380 Saybolt seconds, measured at 100 ° F and 0.5 to 10% by weight of an emulsifier.
- nonionic emulsifiers has proven to be advantageous.
- emulsifiers i.a. Sorbitan esters and polyglycerides of fatty acids specified.
- emulsifier should be present in the emulsion as is just necessary to form a stable emulsion. 0.5 to 10% by weight of the emulsifier is present in the emulsion, with 1 to 50% by weight of emulsifier being preferred. If there is more emulsifier in the emulsion, milky stains or streaks may remain on the cleaned surface after cleaning.
- the manufacture of filters for tobacco products usually takes place according to a process in which a thread, which normally contains cellulose acetate, is first produced using a spinning process, which is preferably the solvent spinning process.
- the solution solidifies into a filament with considerable loss of volume.
- the filaments When using triangular holes, the filaments have a Y cross section.
- the thread When a thread, which is composed of several filaments, leaves the spinning shaft, the filaments are tightly packed in the thread, but without sticking to one another.
- the thread At the exit of the spinning shaft, the thread typically contains a residual proportion of approximately 1 to 6% by weight of acetone.
- the thread is provided with a preparation (finish) which mainly serves as a lubricant for the subsequent processing steps. This preparation is carried out by an oiler or with the help of an application roller.
- the content of acetone in the threads is first further reduced, several threads are combined to form the so-called tau, and the tau is subjected to a crimping process using a crimping machine, which preferably works according to the stuffer box principle.
- this rope is passed through a conical machine part and thus compressed to its final thickness, that is to say the thickness of the filter to be produced.
- a composition containing glycerol triacetate is applied to the filter rope. After leaving the compression part, this further preparation ensures that the filter is fixed in the desired shape and thickness by curing.
- the formulation applied after the threads have dried serves as a lubricant. It ensures, among other things, that the friction that occurs during the subsequent processing steps does not exceed a value that leads to the tearing or undesirable heating of the threads or the rope. Both would result in undesirable waste.
- the lubricant also enables higher machine speeds.
- the formulation must withstand the high shear forces that occur during this process without loss of effectiveness.
- This lubricant usually consists of an emulsion that is made from a mixture of low-viscosity mineral oil and emulsifier. Additional components can be contained in the emulsion.
- the object of the present invention is to provide a stable and storable emulsion which contains highly viscous mineral oils with a viscosity of at least 8.5 mm 2 / s at 100 ° C. For this, it is necessary to find emulsifiers for the production of a processable formulation. The formulation is then used in exchange for the formulations used, which contain low-viscosity mineral oils.
- the object of the present invention is achieved by a formulation for use as a preparation in the production of threads containing a) 30-90% by weight of a mineral oil with a viscosity of at least 8.5 mm 2 / s at 100 ° C. and b) 11 -60% by weight of an emulsifier selected from sorbitan monoesters, derivatives of sorbitan monoesters, sorbitan diesters, derivatives of sorbitan diesters, sorbitan triesters, derivatives of sorbitan triesters, polyglycerol esters, derivatives of polyglycerol esters, polyricin oleate, derivatives of polyricinoleate and mixtures thereof.

- the stability of a formulation which can be in the form of an emulsion, can be determined by the turbidity of the formulation.
- the basic principle here is that higher turbidity indicates lower stability.
- the processing stability of the formulation can be checked by checking the turbidity of the formulation during processing. No or a slight increase in the turbidity is particularly advantageous, while a greater increase in the turbidity indicates insufficient formulation stability.
- the storage stability of a formulation can be checked by checking the turbidity after, for example, five days of storage at 23 ° C.
- the viscosity at 100 ° C. is at least 8.5 mm 2 / s.
- the mineral oil used preferably has a viscosity of 8.5 to 1000, particularly preferably 8.5 to 20 and very particularly preferably 8.5 to 11 mm 2 / s.

- the fatty acids used can alternatively be obtained from corn, cotton oil, palm oil, peanut oil, sesame oil, soybean oil, safflower oil, castor oil or other oils of native origin.
- the fatty acids can be hydrogenated or non-hydrogenated, and condensed or non-condensed.
- the sorbitan triester is selected from the group consisting of sorbitan triesters with fatty acids containing 10-25 carbon atoms, ethoxylated sorbitan triesters with fatty acids containing 10-25 carbons and containing 5-30 moles of ethylene oxide units per mole of sorbitan triesters and mixtures thereof.
