Definitions

  • the present invention relates to the use of compounds with solidification points above 25 ° C., selected from the group of dialkyl ethers with 2 identical or different hydrocarbon radicals, carboxylic acid esters of mono- and / or dicarboxylic acids and aliphatic monofunctional alcohols and esters of two, three and / or tetravalent alcohols and aliphatic monocarboxylic acids as a smoothing agent in combing oils for the production of wool and a method for smoothing wool in the production of wool using the compounds selected from the above group with solidification points above 25 ° C.
  • Wool which is to be processed into ridges, has to be freed from inorganic fiber substances such as sand, dust and salts from wool sweat and from organic fiber substances such as straw, feed residues, wool fat and sweat by an intensive washing process before the spinning process.
  • inorganic fiber substances such as sand, dust and salts from wool sweat and from organic fiber substances such as straw, feed residues, wool fat and sweat
  • the static and dynamic frictional relationships of the wool are greatly changed, so that the further processing of the wool, especially where intensive fiber / fiber and fiber / metal friction occur, extremely becomes problematic.
  • the wool fiber material is particularly stressed during the carding process, in which a fiber structure (carding tape) is produced by parallelization and fine opening.
  • combing oils is accordingly used for the mixture of smoothing agents and emulsifiers.
  • dialkyl ether compounds are known with the same or different saturated and / or unsaturated hydrocarbon radicals having 6 to 24 carbon atoms. These dialkyl ether compounds can also be applied, inter alia, in the form of dispersions as smoothing agents to textile fiber materials of various types, as a result of which a reduction in the friction between fibers and metal is achieved becomes.
  • wool is also treated as textile fiber materials in the above-mentioned published application, there is no indication that especially by treatment with dialkyl ethers with solidification points above 25 ° C., the stack shortening, the combing waste and the electrostatic charge are improved.
  • a mixture of fatty acid esters of fatty acids with 14 to 18 carbon atoms and monohydric alcohols with 1 to 8 carbon atoms, paraffins with a melting range of 40 to 60 ° C. and fatty acid amidopolyamines are known as smoothing agents from German published patent application DE-A-26 21 881. Such smoothing agents thus give treated textile fiber materials, among other things, wool, the smoothness necessary for further processing.
  • British patent specification GB-C-12 90 688 describes textile finishing agents which contain esters of monocarboxylic acids with 16 to 30 C atoms and long-chain monofunctional alcohols with 12 to 30 C atoms. Applied, natural and above all synthetic fibers have the advantage of being dirt-repellent.
  • the object of the present invention was to provide compounds for use in combing oils which impart a good smoothness to wool, minimize stacking, combing waste and electrostatic charging.
  • the connections should be easy to wash out and should not contain any resinous, sticky or even wool-damaging components.
  • the object can be achieved by using compounds with Freezing points above 25 ° C, selected from the group of dialkyl ethers, carboxylic acid esters of mono- and / or dicarboxylic acids with monofunctional alcohols and esters of di-, tri- and / or tetravalent alcohols with aliphatic monocarboxylic acids.
  • the term solidification point stands for the so-called rising melting point as defined in Römpps Chemie-Lexikon, 8th edition, vol. 5, page 3727 f, Stuttgart (1987). Accordingly, the solidification point is the temperature at which the sample, which is located in a capillary suspended on both sides in a water bath, begins to rise in the glass tube.
