Definitions

  • the present invention relates to a method for producing a yarn, in particular a sewing thread, with the features of the preamble of claim 1 and a yarn produced by this method.
  • a number of methods are known for producing yarns by intermingling two yarn components.
  • US-A-40 80 777 describes such a intermingling process for the production of yarns which, viewed over their yarn length, have a different titer due to the alternating presence of thick and thin places.
  • draw-textured yarns or yarns are used as starting materials which are drawn over corresponding pairs of godets immediately before the intermingling.
  • US-A-46 15 167 describes a method for producing a sewing thread, wherein a first thread component serving as a core is provided with a second yarn component used as the effect material are swirled in a nozzle with the aid of a fluid stream.
  • a pre-oriented yarn (POY yarn) is used as the first yarn component, which is pre-drawn using a heated pin before intermingling with the second yarn component.
  • POY yarn a pre-oriented yarn
  • US Pat. No. 4,615,167 proposes to also pre-stretch the second yarn component used as the effect material by means of a corresponding heated pin.
  • EP-A-00 57 583 and the corresponding US-A-44 97 099 also describe a process for producing a swirled yarn.
  • EP-A-46 15 167 proposes at least one pre-drawing of the first yarn component at a drawing ratio which is greater than the drawing ratio recommended for the material used in each case. This is intended to ensure that the loops which form when they are intermingled and cross themselves over themselves are contracted during a subsequent thermal aftertreatment to form a non-crimped, compact yarn.
  • EP-A-0295 601 requires a precise setting of the parameters influencing the yarn loss on the drawing device and a control thereof. These requirements, i.e. the special stretching device as well as its adjustment and control are not necessarily given everywhere.
  • the present invention is based on the object of providing a method of the type specified, by means of which yarns, in particular sewing yarns, having a high strength are particularly easy to produce.
  • the method according to the invention is based on the basic idea of using at least one multifilament yarn as the first yarn component for the production of the yarn, in particular the sewing yarn, which has inherently high strength as the starting material. It is therefore proposed in the method according to the invention to use at least one multifilament yarn as the starting material for the first yarn component, the specific strength of which is between 60 cN / tex and 75 cN / tex and not to pre-stretch this multifilament yarn before intermingling with the second yarn component.
  • the method according to the invention has a number of advantages. For example, it is possible to use a very small amount of mechanical effort to make a thread, in particular sewing thread, to produce, which has excellent properties.
  • the sewing thread thus produced has absolute strengths between approximately 1300 cN and approximately 5500 cN, the corresponding specific strengths varying between approximately 40 cN / tex and approximately 60 cN / tex.
  • the specific strength is defined as the force per titer (cN / tex).
  • These strengths mentioned above mean that the yarn shows no yarn or capillary breaks during further processing, in particular a sewing thread produced by the method according to the invention when sewing, even under extreme loads.
  • the yarn produced by the process according to the invention also has excellent residual shrinkage values, for example the free thermal shrinkage at 160 ° of a dyed yarn between about 0.3% and about 1.5% and the cooking shrinkage of the same yarn below about 1.0%.
  • the first yarn component is usually fed with an advance of the intermingling. This ensures that the yarn produced has a certain volume or a certain crimp, whereby further advantages are achieved. It was found that a certain volume of yarn in the interstices between the individual filaments includes a certain amount of air, which is pressed out when the yarn is deflected, for example on deflecting elements or in the case of a sewing thread in the area of the sewing needle, thereby cooling the deflecting elements or the sewing needle is brought about. This in turn improves the processing properties. Usually the first yarn component with an advance between 1% to 9% is preferred between 2% and 5% fed to the swirling step.
  • the easiest way to achieve this is to feed the first yarn component to the intermingling step via appropriate delivery units, the delivery unit speed being between 1% and 9%, preferably between 2% and 5%, relative to the speed of the take-off unit which transports the intermingled yarn. is higher.
  • a further embodiment of the method according to the invention provides that the first yarn component is wetted with a liquid before the intermingling. If particles are also added to this liquid, as described in German patent application DE-A-38 16 318 by the same applicant, the turbulence can be intensified. This leads to the yarn composite thus formed being particularly stable.
  • the second yarn component with lead is usually also fed to the intermingling step.
  • the volume and the number of loops or loops formed in the intermingled yarn produced can hereby be varied, which in particular has a decisive influence on the previously described air storage capacity of the interlaced yarns and thus also on the processing properties.
  • the second yarn component is usually fed to the intermingling step with an advance of between 14% and 35%, preferably between 20% and 30%.
  • a sewing thread showed particularly good results in industrial sewing tests in which the first yarn component with an advance between 3% and 4% and the second yarn component with an advance between 24% and 26% was fed to the intermingling step. This sewing thread showed no thread or capillary breakage even in long-term use, even under extreme stress, ie a stitch density of 7000 stitches per minute.
  • any starting material can be used as the second yarn component in the method according to the invention.
  • one or more, in particular one to four, multifilament yarns or multifilament yarns are preferably used for this purpose, which are conventional textile standard yarns.
  • Good results with regard to the properties of the yarns produced by the process according to the invention are obtained if pre-oriented yarns (POY yarns) are used as the second yarn component and these pre-oriented yarns are pre-drawn before the intermingling step.
  • This pre-stretching can be carried out, for example, in the known manner using a heated pin. Pen temperatures that vary between 110 ° C and 150 ° C, preferably between 120 ° C and 140 ° C, have proven to be particularly good.
  • the second yarn component is preferably drawn in a ratio which is 2% to 40%, preferably 10% to 25%, below the value at which the yarn in question breaks or breaks capillary breaks occur.
  • a particularly suitable variant of the method which takes into account the above-described problem of different dyeing of the first yarn component relative to the second yarn component to a particular extent and nevertheless enables the production of high-strength yarns, provides that the individual titers of the filaments of the first yarn component and the individual titers of the filaments the second yarn component matches each other.
  • the first and second yarn components dye evenly with regard to the color tone and depth of color if filaments with a single titer between 2 dtex and 5 dtex, preferably between 2.5 dtex and 4, are used for the first yarn component dtex, and for the second yarn component filaments with a single titer between 0.8 dtex and 5 dtex, preferably between 1 dtex and 4 dtex. It is particularly surprising here that the intermingled yarns are dyed uniformly regardless of the material incorporated as the first and second yarn component, these materials always being the same fiber substrate, i.e. polyester fiber, polypropylene or polyamide fiber, of course.
  • swirled yarns the first component of which are multifilament yarns
  • pre-drawn POY yarns and / or high-strength yarns with the have the aforementioned strengths, always evenly if one has taken into account the above-mentioned coordination of the individual titers of the filaments in both yarn components.
  • a non-matted multifilament thread or a plurality of non-matted multifilament threads are used in particular as the second thread component.
  • the sewing properties are further improved compared to a thread which has a matted multifilament thread or matted multifilament threads as the second thread component.
  • B. expresses in a reduced warming of the sewing needle.
  • Such a yarn, which has non-matted filaments as the second yarn component can also be produced at a higher speed by the method according to the invention.
  • the mass ratio of the first yarn component relative to the second yarn component is determined in the method according to the invention.
  • This mass ratio of the first yarn component to the second yarn component can usually be between 90%: 10% to 50%: 50%, preferably between 85%: 15% to 70%: 30%.
  • yarns, in particular sewing threads can be produced particularly well.
  • At least one multifilament yarn is selected for the first yarn component, the strength of which varies between 60 cN / tex and 75 cN / tex.
  • the viscosimetrically determined molecular weight is measured for polyester fibers according to SNV 19 55 91 or for polyamide fibers according to SNV 95 590 or DIN 53 728.
  • other high-strength multifilament yarns can also be used in the method according to the invention, provided that they have the specific strengths mentioned above.
  • the selection of the first yarn component depends on the desired final titer of the intermingled yarn and the desired properties.
  • a multifilament material is usually used for this, the total titre of which varies between 100 dtex and 1000 dtex, preferably between 100 dtex and 600 dtex.
  • the selection of the number of filaments depends on the desired properties in the method according to the invention. So it was found in the area of sewing threads that the inventive Processes with excellent yarns can be produced if a yarn material is used for this as the first yarn component, the number of filaments of which is between 16 and 300, preferably between 24 and 96.
  • the intermingled yarn is wound up under low tension and is then available as finished yarn for further processing. It is also possible to dye the intermingled yarn after the intermingling step, in which case the intermingled yarn is expediently wound directly onto corresponding dye tubes directly after the intermingling step.
  • the subsequent dyeing process in particular with HT dyeing at about 130 ° C., the yarn shrinks by about 2 to 3%, which leads to a reduction in the diameter of the self-intersecting loops or loops, without these being pulled together in knots .
  • Another embodiment of the method according to the invention provides that after the intermingling step and before winding, the yarn thus produced is subjected to a tension treatment.
  • the diameters of the self-intersecting loops and loops formed during swirling are preferably reduced to such an extent that they are reduced by 20% to 95% with respect to their original diameter. It is expressly to be emphasized that, however, this should prevent the loops and loops from contracting into knots, since otherwise the later processing properties of a such yarns, especially a sewing thread, deteriorate. It was thus found that the loops or loops, which are smaller in diameter, bring about very good yarn cohesion, which is desirable in particular because of the high demands placed on a sewing thread during processing.
  • such a sewing thread still has a certain volume, so that air is enclosed within the thread, which is pressed out during sewing thread, in particular when the thread is deflected on thread guide elements or the needle. This in turn causes cooling of the deflection members or the needle, so that no yarn breaks occur with such a yarn, which is not the case with a comparison yarn in which the loops are drawn together like knots.
  • the yarn is fed to the tension treatment at a rate which is between 0.1% and 5%, in particular between 0.1% and 2.5%, less than the rate at which the yarn is withdrawn from the tension treatment.
  • the speed differences mentioned above depend on the one hand on the desired reduction in the diameter of the self-crossing loops and loops and on the other hand on the respectively selected advance of the first and second yarn components.
  • Another embodiment of the method according to the invention provides that in addition to the stress treatment or instead of the stress treatment, a thermal Treatment is carried out before winding the entangled yarn, the temperature of the thermal treatment varies between 100 ° C and 250 ° C, in particular between 180 ° C and 230 ° C.
  • a thermal Treatment similar to the previously described tension treatment taking place at room temperature, results in a reduction in the diameter of the crossing loops and loops, which includes the advantages already set out, in particular in the case of a sewing thread.
  • the thermal shrinkage values of the intermingled yarn are reduced by a thermal treatment, which is furthermore positively expressed when the yarn is subsequently used in the processed state.
  • This thermal treatment is usually carried out with residence times between 0.01 s and 10 s, preferably between 0.05 s and 1 s.
  • tension in the thermal treatment it should be noted that this is carried out without tension or preferably with a certain advance, so that the intermingled yarn treated in this way can shrink.
  • the yarn is fed at speeds of thermal treatment which are 0.1% to 10%, in particular 2% to 4%, higher than the take-off speeds. This prevents undesirable tensions from being frozen in the yarn, which are disadvantageously noticeable in later use, for example in the case of a sewing thread by bolting the seams.
  • a further embodiment of the method according to the invention provides that the intermingled yarn is twisted.
  • the yarn can be twisted between 10 rotations per m and 800 rotations per m, preferably between 100 rotations per m and 600 rotations per m.
  • Such twisting of the yarn can be carried out as an integrated step in one of the methods described above before winding the yarn. In many cases, however, it is better to twist the yarn in a separate step after winding, since otherwise the production speed would have to depend on the relatively slow twisting.
  • a single multifilament thread is used for the first thread component, which has the abovementioned single titer range, the number of filaments and a specific strength between 60 cN / tex and 75 cN / tex has.
  • This multifilament yarn is interwoven with the above-mentioned leads with a second multifilament yarn as the second yarn component, the second yarn component having the single-titer range already mentioned above and being fed to the interlacing step with the aforementioned lead.
  • the intermingled yarn thus produced is then drawn at room temperature under the abovementioned conditions and then transferred to a thermal treatment, the abovementioned temperatures, tensions and residence times being used. Then you wind up the sewing thread thus produced and twist, dye and / or finish it afterwards.
  • a yarn designated as 1 in the electron scanning microscope photo, which is a sewing yarn, has a core material 2 as the first yarn component, which is a multifilament yarn.
