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 ⁇ icarboxylic acids and aliphatic monofunctional alcohols and esters of two, three- and / or tetravalent alcohols and aliphatic monocarboxylic acids as smoothing agents 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 aforementioned 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 through 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 conditions of the wool are greatly changed, so that the wool is further processed, particularly where intensive fiber / fiber and fiber / me ⁇ tall friction occurs, becomes extremely problematic.
- the wool fiber is subjected to severe aterial stress.
- 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 fibers of different 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 published patent application, there is no indication that treatment with dialkyl ethers with solidification points above 25 ° C. improves stack shortening, combing waste and electrostatic charging.
- British patent specification GB-C-1290688 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 compounds should be easy to wash out and should not contain any resinous, adhesive or even wool-damaging constituents.
- 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 present invention relates to the use of one or more compounds with solidification points above 25 ° C., selected from the group
- dialkyl ethers with 2 identical or different aliphatic hydrocarbon radicals, each with 6 to 22 C atoms,
- 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.
- the smoothing agents used according to the invention should all have a solidification point above 25 ° C. Preference is given to compounds which have a solidification point of from 30 ° C. to 100 ° C. and especially up to 80 ° C.
- the physical state, defined by the solidification point, of the compounds used according to the invention is essential to the invention, since solid connections in the sense of the invention should only be used at room temperature. For example, our own comparative tests have shown that compounds with a comparable chemical structure show significantly different friction values, wool lengths and combing waste, depending on the solidification points of the compounds.
- the dialkyl ethers according to the invention are commercially available products and are generally prepared by catalytic dehydration of alcohols or by reacting alkyl halides with alcoholates (Williamson synthesis), for example as described in Ullmann's Encyclopedia of Industrial Chemistry, 4th ed., Vol. 8 (1974), pages 146-156, Verlag Chemie, Weinheim.
