  • intermingled single yarns which do not have the core-sheath structure described above.
  • the multifilament yarn consisting of individual filaments is fed to the nozzle with a certain advance and swirled over an air stream in such a way that the individual filaments are confused with themselves, so that a yarn which is closed per se results.
  • the mechanical-technological properties are then considerably deteriorated, which can be expressed, for example, in the case of a sewing thread in a reduced strength, a deterioration in the force-elongation ratio and / or in an increase in the frequency of thread breakage during sewing.
  • the present invention has for its object to provide a yarn of the type specified, which has a particularly low frequency of yarn breakage during processing.
  • the yarn designed according to the invention which is used in particular as a sewing thread, consists of at least one first yarn component designed as a core and at least one second yarn component intermingled with the first yarn component, the second yarn component being arranged predominantly in relation to finished yarn in the outer region thereof.

  • the grain-like particles have a grain diameter of between approximately 4 ⁇ m and approximately 400 ⁇ m. Your concentration is between about 0.02% by weight and about 20% by weight, each based on the weight of the yarn.
  • the mechanical-technological properties and the processing behavior are considerably improved in comparison with a conventionally designed, equivalent yarn which does not have such granular particles.
  • This is expressed, for example, in that the yarn strength is improved by approximately 15% compared to the standard yarn described above, while at the same time the elasticity is improved in the yarn according to the invention.

  • titers i.e.
  • Titers in the range between approximately 500 dtex and approximately 800 dtex may require higher concentrations of granular particles, these concentrations usually being in a range between approximately 0.5% by weight and approximately 4% by weight.
  • concentrations in the order of magnitude between approximately 5% by weight and approximately 15% by weight may be required in order to achieve the above-mentioned favorable properties, with all of the above-mentioned yarns, the particle concentration for the respective yarn depends on the number of filaments, the distribution of the particles over the yarn cross-section and the particle diameter.
  • Such embodiments have particularly good mechanical properties and advantageous processing behavior of the yarn according to the invention, in which the granular particles have a grain diameter between approximately 20 ⁇ m and approximately 100 ⁇ m.

  • the desired improvement in properties depends crucially on the fact that the friction between the filaments is effectively reduced, which is achieved by embedding the particles in the spaces between the filaments.
  • Another advantageous embodiment of the yarn according to the invention provides that the grain-like particles are embedded in a finish applied to the yarn.
  • the finish supports the effect of the grain-like particles in reducing friction, while the finish improves the adhesion of the grain-like particles to the yarn or the individual filaments processed therein.

  • Inorganic particles such as talc, kieselguhr and aluminum oxide are particularly suitable.
  • the yarn according to the invention can be processed wherever a high mechanical load on the yarn occurs during processing and / or high strength and excellent elasticity behavior of the yarn is required.
  • the use of the yarn according to the invention as a sewing thread brings considerable advantages compared to a correspondingly designed conventional thread, as will be demonstrated below by the exemplary embodiments.

  • the arrangement of the particles the distribution, their size, their concentration and their chemical structure, the same applies as has been described above for the core-sheath yarn designed according to the invention.
  • the particles may accumulate in the outer region of the yarn, since the yarn according to the invention is usually produced as described below and only afterwards is colored. During the dyeing of the yarn according to the invention, the particles in the outer yarn area can accumulate, particularly in the case of very open yarns, but such an enrichment does not cause any undesirable side effects.

Instead, in the process according to the invention, grain-like particles are added to the water with which the first yarn component is wetted, the grain-like particles having a specific weight greater than 1 g / cm 3. The first yarn component is thus wetted with an aqueous dispersion or suspension of the granular particles.
  • the method according to the invention has a number of advantages.
  • the yarns produced by this process are distinguished by a particularly uniform titer, which is attributed to the fact that the flow conditions in the nozzle are optimized and / or evened out by the additional particle flow in the swirl chamber.
  • the particle flow causes any matting of the first yarn component to be loosened, which in turn improves the yarn uniformity.
  • the particle flow also prevents the deposit of dissolved or lubricated preparations and additives in the nozzle, so that undesirable and uncontrollable changes in the dimension of the nozzle due to deposits or lubrication do not occur in the process according to the invention during production, which on the one hand causes the flow conditions in the nozzle can also be kept constant over a longer production period and, on the other hand, undesirable Knot formation and / or capillary or yarn breaks can be prevented.
  • the yarns described above can be produced by the method according to the invention over a longer period without interruption and without necessary cleaning of the nozzle, so that no significant downtimes for cleaning the nozzle and / or the reinsertion of the nozzle can be achieved in the method according to the invention Yarns occur when yarn breaks occur.

  • Grain-like particles whose specific weight is between approximately 1 g / cm 3 and approximately 6 g / cm 3, in particular between approximately 2 g / cm 3 and approximately 4.5 g / cm 3, are preferably used in the process according to the invention, it being particularly advantageous has proven to vary the specific weight of the granular particles depending on the yarn to be processed.
  • the hardness of the particle particles used is also important for the desired effects.
  • the granular particles should not be so soft that they are destroyed during the swirling and on the other hand they should still have a certain softness in order not to cause unwanted capillary injuries and / or undesirable damage to the nozzle.
  • Grain-like particles are usually used which have a hardness on the Mohs hardness scale of between approximately 1 and approximately 7, in particular between approximately 4 and approximately 6 1/2, but also the hardness, as already explained above for the density of the grain-like particles, depends on the yarn used and its number of filaments.
  • the grain size of the particles used can also vary in a range between approximately 4 ⁇ m and approximately 400 ⁇ m, in particular for the production of yarns with an average titer between approximately 300 dtex and approximately 600 dtex grain-like particles with a grain diameter between approximately 20 ⁇ m and approximately 100 ⁇ m can be used.
  • particles with a grain size of between approximately 20 ⁇ m and approximately 50 ⁇ m are preferred, and in the case of the coarser titers of the individual filaments or of the finished yarn preferably also larger grain-like particles, for example, those in a range between approximately 150 ⁇ m and approximately 250 ⁇ m can be used.
  • the concentration of the granular particles in the aqueous suspension or dispersion depends on the type of wetting of the first yarn component. If the first yarn component is wetted by immersion in an aqueous suspension or dispersion of the granular particles, the concentration is usually in a range between approximately 45 g granular particles / l and approximately 150 g particles / l, preferably a concentration range between approximately 30 g Particle / l and about 60 g particle / l is selected.
  • particle concentrations between about 10 g / l and about 200 g / l, preferably between about 50 g / l and about 150 g / l, are preferably used .
  • a further embodiment of the process according to the invention provides that surfactants and / or dispersing agents or suspending agents are added to the aqueous suspension or dispersion of the granular particles.
