Definitions

  • the present invention relates to a yarn, in particular a sewing thread with the features of the preamble of claim 1 and a method for producing such a yarn with the features of the preamble of claim 17.
  • Such yarns can in principle be spun from multifilament fibers, from staple fibers or a mixture of multifilament fibers with staple fibers, such a yarn also being able to be twisted in order to improve the thread closure and thus the resistance of the yarn to mechanical stresses.
  • threads are often used which consist of at least two, usually multifilament thread components, these two thread components twisted together being of the same design both in terms of the number of filament threads, the titer and in terms of strength.
  • yarns in particular sewing yarns, are known which are formed from at least two multifilament yarn components, the two yarn components being intermingled with one another by a fluid flow in order to produce such a yarn such that the first yarn component is predominantly arranged in the core of the spun yarn and from is therefore also referred to as the core component and the second yarn component is predominantly located in the outer region of the spun yarn and is therefore referred to as the sheath component or layer.
  • the sheath component has a substantially greater length, which means that the sheath component (overlay) gives a certain volume to such a core-sheath yarn, forming loops, self-crossing loops and / or arches.
  • These core-sheath yarns generally have excellent properties with regard to mechanical resistance, so that they are increasingly being used for sewing threads that are exposed to extreme mechanical stresses during processing.
  • DE-OS 38 34 139 proposes to form the core yarn component and the sheath yarn component from the same, high-strength material.
  • the specific strength of the multifilament core yarn component and the multifilament sheath yarn component according to DE-OS 38 34 139 is at least 40 cN / tex, but preferably more.
  • the present invention has for its object to provide a core-sheath yarn of the type specified, which has a particularly good mechanical resistance.
  • the yarn according to the invention which is also used in particular as a sewing thread, comprises at least two multifilament yarn components, the first yarn component predominantly forming the core of the yarn and the second yarn component predominantly forming the jacket of the yarn.
  • the two yarns are intermingled, which leads to the fact that the core material, viewed in the axial direction of the spun yarn, runs straight or almost straight, while the multifilament sheath yarn (overlay) with the formation of loops, self-crossing loops and / or arcs with the core yarn is swirled and completely or almost completely envelops this core yarn, so that such a yarn has a certain volume and thus a certain bulk.
  • the individual filaments of the second yarn component have a specific strength which is between 5% and 70%, in particular between 10% and 50%, of the specific strength of the individual filaments of the first yarn component.
  • the yarn according to the invention has a number of advantages. It was thus found that such a yarn is particularly good, i.e. without thread break, can be processed. This is attributed to the fact that thread suspensions, which are to be regarded as a preliminary stage for a thread break, do not occur in the yarn according to the invention. Rather, it was recognized that in the yarn according to the invention, individual filaments that are present during processing on certain machine parts, for example on deflection rollers, thread brakes on the needle of a sewing machine and the like.
  • the overlay is made from a material whose individual filaments are deliberately low in strength, whereby these individual filaments tear with a slight interlocking, so that the formation of thread suspensions and consequently the subsequent breakage of the entire thread is increased prevent.
  • the superiority of the invention Yarns in comparison to a conventional swirled core-sheath yarn is particularly evident when a sewing thread is made from the yarn according to the invention. It could be determined on the basis of high-speed video recordings during sewing that in the sewing thread according to the invention, the individual filaments of the cover, which get caught during sewing on sewing machine parts, in particular on the hook and / or the needle, immediately tore due to the predetermined low specific strength, without there was a noticeable slowdown in the forward movement of the sewing thread. Furthermore, it was observed with the yarn according to the invention that the looping of the needle thread required for sewing went smoothly, even if protruding individual filaments got caught.
  • the conventional sewing thread was significantly slowed down when the protruding filaments got caught, since the hooked individual filaments did not tear, so that corresponding deferrals were formed and afterwards the thread as a whole tore or did not sew, since the loops of the needle thread mentioned earlier did not or only were insufficiently trained.
  • the thread according to the invention as a sewing thread has a significantly improved sewing behavior compared to a conventional sewing thread, that is to say with the sewing thread according to the invention it is possible under industrial sewing conditions (5000 to 7000 stitches per minute) without thread breakage create up to 50% more buttonholes or 40 to 60% longer seams.
  • the first possibility provides that a multifilament yarn component is used for the overlay, which already has the specific strength indicated above over its axial length.
  • the yarn according to the invention has individual filaments in the overlay which, viewed in the axial direction, have first areas in which the specific strength of the individual filaments is between 5% and 70%, in particular between 20% and 50%, based on the specific strength of the Individual filaments of the first yarn component lie.
  • all of the individual filaments of the overlay have a plurality of predetermined breaking points, as seen in the axial direction, so that if the individual filaments get caught during processing, the individual filaments can tear in these first areas (predetermined breaking points), thereby preventing the formation of suspensions and a total yarn breakage .
  • the first possibility reproduced above includes an embodiment of the yarn according to the invention, in which the first and second yarn components consist of the same material. Furthermore, the material of the second yarn component has a degree of polymerization which is less than the degree of polymerization of the material from which the first yarn component is made.
  • a multifilament synthetic material for example made of polyester, polyamide 6, polyamide 66, polyethylene or polypropylene, is preferably used as the second yarn component (sheath component), the average molecular weight of which is between 5% and 40%, in particular between 15% and 25%, is below the average molecular weight of the synthetic fiber material of the first yarn component, the average molecular weights being determined viscosimetrically in a conventional manner by the known standards.
  • a preferred embodiment of the yarn according to the invention has a second yarn component in which all the individual filaments or at least the outer filaments seen in the yarn cross section, which give the yarn a certain volume by forming the loops mentioned above, self-crossing loops or arches, an absolute single filament strength less possess than 3.5 cN.
  • the sewing properties of the sewing thread according to the invention are particularly good when the sewing thread comprises a second thread component whose absolute individual filament strength is between 0.5 cN and 3 cN, in particular between 0.8 cN and 2 cN. It is irrelevant whether these absolute single filament strengths are achieved in that the multifilaments have corresponding first areas, i.e. predetermined breaking points, or that the multifilaments have the aforementioned constant single filament strengths over their entire length.
  • multifilament yarns whose individual filament titers vary between 0.4 dtex and 1.4 dtex, in particular between 0.5 dtex and 0.7 dtex, are preferably used for this.
  • Multifile second yarn components with such a fine single filament titer ensure that at low mechanical stress due to a hooking of the filaments, these break, so that the formation of thread suspensions and, as a result, the occurrence of yarn breaks is prevented in the yarn according to the invention.
  • the individual filament titer of the second yarn component can also be higher than the titer given above, in particular in a range between 1.4 dtex and 2.5 dtex. It is only necessary to ensure that the individual filaments tear accordingly if they get caught during processing.
  • the strength of the first yarn component which in the yarn according to the invention is arranged predominantly inside the yarn over its cross-section and which is completely or almost completely covered by the second yarn component (overlay), it should generally be stated that the strength of the first yarn component after the the intended use of the finished yarn.
  • Multifilaments with a specific strength between 40 cN / tex and 270 cN / tex are usually used for this.
  • sewing threads for normal sewing operations fully meet the requirements regarding the resilience when sewing when the specific strength of the multifilaments of the first thread component is between 60 cN / tex and 120 cN / tex.
  • any multifilament yarn is suitable for this purpose, which in particular has the strengths given above.
  • the high-strength polyester types with a specific strength up to 90 cN / tex
  • polyamide 6 with a specific strength also up to 90 cN / tex

  • high-strength polyethylene fibers especially those made from Gel-spun high-strength polyethylene fibers with a specific strength of 270 cN / tex
  • aromatic polyamide fibers (aramids) with a specific strength of 230 cN / tex
  • carbon fibers glass fibers and / or silicate fibers.
  • the individual filament titer of the first yarn component varies in the yarn according to the invention between approximately 0.4 dtex and 5 dtex, preferably between 0.8 dtex and 4 dtex.
  • the number of filaments of the first yarn component is between 16 and 300, in particular between 24 and 96, while the second yarn component has at least one multifilament yarn, the number of filaments of which varies between 20 and 400, in particular between 36 and 120.
  • the total titer of the yarn according to the invention varies between 50 dtex and 500 dtex, preferably between 80 dtex and 300 dtex.
  • a particularly suitable embodiment of the yarn according to the invention which is preferably used as a sewing thread, provides that the mass ratio of the first yarn component to the second yarn component is between about 90:10 to about 50:50, preferably between about 80:20 to about 60:40, is.
  • the foregoing has spoken of single filaments getting caught in the processing of the yarn. This includes all filament parts protruding from the longitudinal axis of the yarn, in particular also the loops formed and / or loops crossing each other during the intermingling.
  • a particularly suitable embodiment of the yarn according to the invention which can also be used particularly well as a sewing thread, provides for a specific arrangement of the first and second yarn components.
  • the second yarn component over the cross-section of the spun yarn takes up an area F 2 that is two to thirty times, in particular five times to fifteen times, as large as the area F1 that the first yarn component occupies (on the same cross-sectional area).
  • F 1 and F 2 a large number, in particular 50 to 150 cross sections, are produced from the spun yarn over a predetermined length, in particular over a length of 1 meter to 4 meters.
  • the area F1 which occupies the first yarn component is then determined in such a way that a circle with the smallest possible radius is drawn in such a way that all the filaments of the first yarn component lie within this circle.
  • the area F 1 on this specific cross section is then calculated from this, taking into account the aforementioned smallest possible radius.
  • the mean bil The result of the different cross-sectional areas then gives the corresponding value for the area F1.
  • the same method is used to determine the mean value of the cross-sectional area F2, which takes up the individual filaments of the second yarn component, with the second circular area F 2 being positioned in such a way that the center of the second circular area is placed in the center of the first circular area with each cut becomes.
  • the present invention is also based on the object of providing a method of the type specified, by means of which the yarn according to the invention described above can be produced particularly simply and economically.
  • the method according to the invention for producing a yarn provides that at least one first multifilament yarn component is swirled together with at least one second multifilament yarn component by means of a fluid stream, in particular a gas stream.
  • a yarn material is selected as the second yarn component whose individual filaments have a specific strength which is between 5% and 70%, preferably between 10% and 50%, of the specific strength of the individual filaments of the first yarn component.
  • first areas which are also referred to above as predetermined breaking points, can be produced in various ways.
  • a first variant of the method according to the invention provides that, in order to produce the first regions, the multifilament material of the second yarn component is stretched unevenly over the length of the second yarn component before intermingling with the first yarn component.
  • the individual filaments of the second yarn component are preferably drawn less in the first regions.
  • a conventional stretching device for example, by asymmetrically mounting the take-off godet around which the multifilament yarn to be drawn is guided. This then leads to the fact that with each rotation of the take-off godet the multifilament yarn of the second yarn component guided around it is drawn less in this first area, forming a less stretched first area (predetermined breaking point), so that the material in the first area has the aforementioned specific strengths .
  • the godet is preferably stored asymmetrically in such a way that a stretching ratio is generated which is between 30% and 90%, preferably between 60% and 80%, below the usual stretching ratio.
  • a second method variant of the method according to the invention provides that to produce the first areas (predetermined breaking points) in the multifilament yarn of the second yarn component, a relatively short distance in yarn length, which is preferably between 0.01 mm and 0.5 mm, is thermally treated. As a result, the corresponding yarn material is deliberately thermally damaged in the first area, with the result that the strength is correspondingly reduced in this first area.
  • the thermal treatment is preferably carried out on the multifilament yarn of the second yarn component before the intermingling of the second yarn component with the first yarn component, although it is of course also possible to carry out such a thermal treatment on the already intermingled yarn , since here the second yarn component is predominantly arranged in the outer layer of the yarn.
  • the thermal treatment of the corresponding first areas can take place either by direct contact of the yarn component to be treated or the spun yarn with an appropriate heating element or indirectly, in which case contactless treatment with pulsed laser beams is particularly suitable.
  • Another embodiment variant of the method according to the invention provides that the multifilament yarn of the second yarn component is chemically degraded in the first areas to produce the first areas, preferably by hydrolysis. This then has the consequence that the average molecular weight of the yarns treated in this way in the first areas compared to be neighboring areas considerably, for example by about 30% to about 60%, so that the yarn material inevitably experiences a corresponding loss of strength in the first areas.
