  • the invention further concerns a water in oil emulsion comprising the composition, a process in which they are applied to fibres or tow, fibres or tow comprising the composition and cigarette filters comprising such fibres or tow, wherein the fibres to tow are cellulose acetate fibres or tow.
  • auxiliary formulations are applied to the fibres and tows to avoid wear and rupture of the fibres, avoid electrostatic charging of fibres and reduce dust formation on fibres and roller points.
  • these formulations comprise mineral oils, at least one emulsifier and water.
  • Such formulations are described, for example, in WO2004007831 .
  • hydrocarbons which are liquid at 20°C obtained by a process of converting syngas into at least one hydrocarbon which is liquid at 20°C, are suitable for being used in compositions that can be employed as auxiliary formulations in the manufacture of fibres and yarns.
  • the compositions of the present invention often display several advantages, such as good lubricating properties, high viscosity index, low evaporation loss, stability of the composition, advantageous impurity profile and thus toxicology, stability against discoloration and staining, light stability, lower dust level in fibre production and, being manufactured from non-mineral hydrocarbon sources such as natural gas, are advantageous in view of environmental sustainability.
  • the invention thus concerns a composition
  • a composition comprising at least one hydrocarbon which is liquid at 20°C, obtained by a process of converting syngas into at least one hydrocarbon which is liquid at 20°C, at least one emulsifier and at least one aqueous phase, and a water in oil emulsion, comprising the composition.
  • Another subject of the present invention is a process for making fibres or tow in which the composition or water in oil emulsion is applied to fibres or tow.
  • Yet another object of the present invention is the use of the composition or water in oil emulsion in a manufacturing process as an auxiliary for the spinning of fibres, fibres or tow comprising the composition or water in oil emulsion and cigarette filters comprising such fibres or tow, wherein the fibres or the tow are cellulose acetate fibres or cellulose acetate tow.
  • the composition according to the present invention can also be denoted as fibre finish, spinning finish or lubricant.
  • the "at least one hydrocarbon which is liquid at 20°C, obtained by a process of converting syngas into at least one hydrocarbon which is liquid at 20°C” is a liquid hydrocarbon which is obtained by a catalysed process from syngas.

  • Fischer-Tropsch-processes a mixture comprising carbon monoxide CO and hydrogen H 2 , the so-called “syngas”, is converted at elevated pressures, temperatures and in the presence of at least one catalyst, into a mixture of hydrocarbons.
  • Desired chain lengths and isomerizations of the hydrocarbons can be steered by choosing the corresponding reaction conditions, such as temperature, pressure, syngas composition or presence of water.
  • Syngas can be obtained by methods as gas to liquid (GTL) technology, wherein low molecular weight hydrocarbon materials, such as methane or natural gas mainly comprising methane, are converted into syngas.

  • the liquid hydrocarbons according to the present invention generally display a number of different characteristics, such as advantageous viscosity index and low evaporation losses. An advantageously high viscosity index indicates that the viscosity of the liquid hydrocarbon is relatively unaffected by temperature changes.
  • the composition according to the present invention comprises further at least one emulsifier.
