Definitions

  • the present invention relates to a sewing thread according to the preamble of patent claim 1 and a method for producing a sewing thread according to the preamble of patent claim 6.
  • DE-PS 37 20 237 or European patent application 88109358.7 which goes back to the applicant of the present patent application, each describes a process for the production of a sewing thread, in which the sewing thread comprises a multifilament core material and a multifilament sheath material Core material is swirled together with the cladding material under the influence of a fluid flow.
  • profiled fibers or filaments or yarns which consist of profiled fibers or profiled filaments for the production of sewing thread.
  • This profiling which is expressed, for example, in a polygonal, T-shaped or Y-shaped cross section, is produced by selecting a corresponding nozzle during primary spinning, such a macrostructure occurring exclusively in the longitudinal direction of the fibers or filament and the yarn produced therefrom extends.
  • the present invention has for its object to provide a sewing thread of the type specified, which has particularly good sewing properties.
  • a mowing yarn which is structured on its surface.
  • the sewing thread consists of spun, twisted and / or intermingled fibers, filaments and / or yarns, the structuring being designed as a microstructuring and comprising punctiform, linear and / or planar depressions and / or punctiform, linear and / or planar elevations.
  • the microstructuring extends over the entire surface of the sewing thread forming fibers, filaments and / or yarns, so that, seen across the cross section of the finished sewing thread, all the fibers, filaments and / or yarns processed therein have the aforementioned microstructuring or roughening on their surfaces. This is true even if the sewing thread according to the invention has a very compact structure, that is to say a very high thread closure, for example by subsequent twisting.
  • the sewing thread according to the invention has a number of advantages. For example, in sewing trials, it was found that the sewing thread according to the invention differs from an otherwise identical sewing thread, i. H. a sewing thread, the surface of which is not microstructured or roughened in the manner mentioned above, behaves much better, d. H. showed significantly fewer thread breaks, especially in industrial sewing tests, as is described below in the exemplary embodiments.
  • the reason for the above-described improved sewing behavior of the sewing thread according to the invention is assumed to be that, due to the microstructuring or roughening of the surfaces of the fibers, filaments and / or yarns forming the sewing thread, the thread closure of the sewing thread is improved, so that the sewing thread according to the invention has deferrals of individual fibers or filaments as a preliminary stage of a thread break can be seen, cannot occur.
  • This assumption is supported by the fact that the mowing thread according to the invention can be processed under ready-made conditions in the non-activated state in comparison with a corresponding conventional sewing thread which does not have the microstructuring, which is not the case with the non-activated conventional sewing thread.
  • the sewing thread according to the invention seems to absorb the finishing applied thereon much better and more uniformly than a corresponding conventional sewing thread, which is to be regarded as a further cause for the improved sewing behavior of the sewing thread according to the invention.
  • the microstructuring preferably consists of circle-like and / or circular depressions and / or elevations, the term circle-like also meaning angular shapes whose shape approximates a circle.
  • the depressions have a depth or the elevations have a height between approximately 0.01 ⁇ m and 0.3 ⁇ m, preferably between 0.18 ⁇ m and 0.25 ⁇ m .
  • this means that a particularly suitable embodiment of the sewing thread according to the invention has the above-described microstructuring or roughening only in a relatively thin surface layer, so that the strengths of the fiber, the filament or the yarn are not impaired by these depressions or elevations becomes.
  • the width of the punctiform, line-shaped or planar depressions or punctual, line-shaped or planar elevations varies in the sewing thread according to the invention between 0.1 ⁇ m and 4 ⁇ m, preferably between 0.1 ⁇ m and 2 ⁇ m.
  • the axial and radial distances from adjacent punctiform, line-shaped or planar depressions or from neighboring punctual, line-shaped or planar elevations are 0.01 ⁇ m and 2 ⁇ m, preferably 1.2 ⁇ m and 2 ⁇ m.
  • the invention is also based on the object of providing a method of the type specified by which the sewing threads described above can be produced in a particularly reproducible manner.
  • a method is thus claimed in which the fibers, filaments and / or yarns are spun, twisted and / or intermingled to produce the sewing thread, and then the sewing thread thus produced is optionally dyed, dried, fixed, finished and / or wound.
  • the fibers, filaments and / or yarns used as starting material for the production of the sewing thread are subjected to a high-temperature plasma treatment or a corona treatment before the spinning, twisting and / or intermingling.
  • the process is subjected to the low-temperature plasma treatment or corona treatment of the starting materials and then the sewing thread is produced from the starting materials treated in this way by the known measures described at the outset.
  • the method according to the invention has a number of advantages. For example, it can be carried out particularly easily since no special starting material is required for this. Rather, the starting material used is the starting material which is used in any case for the production of a conventional sewing thread, this starting material, as already described several times above, being subjected to a corona or low-temperature plasma treatment before spinning, twisting and / or intermingling. It was also found that there was a starting material treated in this way can be better spun, twisted or swirled, since, as already described above, the thread closure between the yarn components forming the sewing thread is improved by the low-temperature plasma treatment or corona treatment.
  • a particularly suitable embodiment of the method according to the invention provides that before the low-temperature plasma treatment or corona treatment a pile is produced from the fibers, filaments and / or yarns and that the pile is treated with a gas during the low-temperature plasma treatment or corona treatment flows through.
  • Such a procedure has the advantage that it is very easy to carry out on the one hand, since no large-volume facilities are required for this.
  • a sewing thread which was produced by the method according to the invention is, compared to a conventionally produced but otherwise identical sewing thread, preferably essential when sewing longitudinal seams and when sewing buttonholes showed fewer thread breaks, so that with the sewing thread produced according to the invention an approximately 10 to about 20 times longer seam or an approximately 10 to about 30 times the number of buttonholes could be produced.
  • the measured thread tensions fluctuate between approximately ⁇ 2% and approximately ⁇ 8% of the mean thread tension value, while in the case of the conventionally produced comparison thread the deviations from the mean value lie between approximately ⁇ 15% and ⁇ 25%.
  • a pressure of between about 5 Pa and 500 Pa is used.
  • the low-temperature plasma treatment is carried out under a vacuum between 50 Pa and 300 Pa, preferably between 70 Pa and 200 Pa.
  • Another embodiment of the method according to the invention provides that in the low-temperature plasma treatment, a vacuum between about 5 Pa and about 120 Pa, preferably between about 20 Pa and 120 Pa, during a first treatment period and a vacuum during a subsequent second treatment period between about 80 Pa and 250 Pa, preferably between about 100 Pa and about 200 Pa.
  • a vacuum between about 5 Pa and about 120 Pa, preferably between about 20 Pa and 120 Pa, during a first treatment period and a vacuum during a subsequent second treatment period between about 80 Pa and 250 Pa, preferably between about 100 Pa and about 200 Pa.
  • the transition from the first treatment period to the second treatment period and from the second treatment period to the first treatment period can be designed in such a way that the vacuum is suddenly set in each treatment period.
  • a particularly gentle treatment of the pile enables an embodiment of the method according to the invention, in which the vacuum in the first treatment period is continuously converted into the vacuum of the second treatment period and the vacuum in the second treatment period is continuously transferred into the vacuum of the first treatment period, so that the pressure during the overall treatment e.g. B. is increased or decreased sinusoidally.
  • the residence time of the first and second treatment periods is varied between 10 seconds and 160 seconds, preferably between 20 seconds and 60 seconds.
  • the frequency in the low-temperature plasma treatment is usually between 1 MHz and 20 MHz, with particularly good results being achieved at a frequency of 13.56 MHz.
  • the low-temperature plasma treatment can be carried out at a frequency of 27.12, 40.68 and / or 81.36 MHz, although it is also possible to use the frequencies in the aforementioned during the low-temperature plasma treatment Change range or set to different values within the scope of the aforementioned values.
  • the power density in the low-temperature plasma treatment varies between 2 W / dm3 and 25 W / dm3, the volume information relating to the volume of the autoclave.
  • the power in the method according to the invention is between 200 W and 600 W.
  • this corona treatment is carried out at a pressure which is at normal pressure and / or slightly above and / or slightly below normal pressure.
  • the corona treatment is carried out at a pressure between 86.659 x 103 Pa and 133.32 x 103 Pa, preferably at a pressure between 93.325 x 103 Pa and 113.324 x 103 Pa.
  • the pressure change between the first and second treatment periods can be carried out abruptly.
  • the abrupt pressure change causes the pile to move in an undesirable manner, so that, especially in the case of relatively soft packed piles, ie those piles where the Shore hardness is low, a continuous pressure increase or pressure during the transition from the first treatment period to the second treatment period a continuous pressure reduction is carried out during the transition from the second treatment period to the first treatment period.
  • This pressure increase or pressure reduction can then preferably be carried out sinusoidally, with treatment times between 10 seconds and 160 seconds, preferably between 20 seconds and 60 seconds, being selected for the first period and the second period.
  • the autoclave used for the corona treatment is preferably evacuated to a pressure between 1000 Pa and 10,000 Pa, so that the respective gas which flows through the pile can then be supplied in order to bring the pressure in the autoclave to a value between 86.659 x 103 Pa and 113.324 x 103 Pa.
  • the corona treatment can also be carried out at normal pressure, it only being necessary to ensure that the gas used in the corona treatment also flows through the aggregate.
  • a further embodiment variant of the method according to the invention provides that instead of the aforementioned highly reactive gases, an inert gas, preferably an inert gas, a mixture of noble gases and / or nitrogen is used as the gas. This ensures that the risk of a chemical change in the materials treated in this way is reduced.
  • the reactive gases mentioned above can be used in the corona or low-temperature plasma treatment. If, for example, fibers, filaments and / or yarns made of polyethylene terephthalate are flowed through with basic, reactive gases during the low-temperature plasma treatment or during the corona treatment, this results in a material treated in this way after the treatment with acid dyes can be dyed. It is also possible to flow through the aforementioned substrates with an acidic, reactive gas during the corona or low-temperature plasma treatment, as a result of which the substrates treated in this way can then be dyed with basic dyes.
  • a mixture of acidic or basic gases can also be used instead of a basic or an acidic gas.
  • the substrates treated and subsequently dyed surprisingly have high color fastnesses, with the subsequent dyeing being made considerably easier in comparison with conventional dyeing with disperse dyes, which is reflected in correspondingly reduced dyeing temperatures and considerably shorter dyeing times. It was also found that ionic preparations had a much better adhesion to the substrates chemically modified in the above manner, which was expressed in particular by a further improved sewing behavior of the sewing threads produced therefrom.
  • such materials are used in the method according to the invention which are usually used for the production of sewing threads.
  • This can either be pure synthetic fibers, pure natural fibers or a mixture of natural and synthetic fibers.
  • polyester, polyamide 6, polyamide 6.6 and / or cotton fibers in the fineness and number of filaments that are customary for sewing threads are to be mentioned.
  • the total treatment time in the method according to the invention is between about 2 minutes and about 30 minutes, preferably between about 5 minutes and about 20 minutes, depending on the desired effects and the power densities set.
  • a winding body is produced from the fibers, filaments and / or yarns, the winding of these materials in particular being preferably used on a perforated sleeve, preferably on a perforated metal sleeve.
  • heaps this includes any orderly, uniformly flowing product presentation, such as a fiber cake or a card sliver that is wound up appropriately in the case of fiber (flake), or a corresponding winding body in the case of filaments or yarns, to understand.
  • Polyester fibers with a staple length of 38 mm and a single fiber strength of 1.3 dtex are packed in a product carrier commonly used for dyeing flake and subjected to a low-temperature plasma treatment there.
  • the conditions for the low temperature plasma treatment were as follows: Pressure before the low temperature plasma treatment : 5 Pa frequency : 13.56 MHz Power density : 12.5 W / dm3 Pressure curve during the plasma treatment : Illustration 1 Duration of the first and second treatment period : 40 seconds each Total duration of treatment : 10 mins gas : Oxygen
  • a card sliver was then produced from the fibers treated in this way after opening and carding, and this card sliver was spun on a conventional spinning machine (manufacturer Marzoli).
  • the resulting yarn had a fineness of approximately 140 dtex. Then two of these yarns were twisted on a twisting machine with 1000 turns per meter.
  • a comparative material was produced which differs from the yarn described above in that its fibers have not been subjected to low-temperature plasma treatment before spinning.
  • the material 1 made from fibers which have been subjected to a low-temperature plasma treatment has an excellent sewing behavior.
  • the sewing attempts were stopped after a seam length of 100 m, since no thread breakage occurred even in 10 sewing tests with a seam length of 100 m each.
  • the untreated comparison material is much worse, since it only allowed 4 - 6 buttonholes and a seam with a length of 10 meters to be sewn.
  • Two 1kg bobbins of a polyester multifilament yarn f34, 160 dtex were subjected to a low-temperature plasma treatment as a bobbin on a conventional perforated dye tube.
  • this low-temperature plasma treatment in Example 2 was carried out at a power density of 8 W / dm3 and a treatment time of 15 minutes, with this embodiment also working with 2 treatment periods, the duration of which was 20 seconds each .
  • the pressure conditions during these treatment periods can be seen in Figure 2 below.
  • oxygen was passed through the winding body during the low-temperature plasma treatment.
  • a core-jacket sewing thread was also produced using the same process using the same starting materials, which also had a twist of 350 twists per meter.
  • This comparison material differed from the material described above in that the starting materials were not subjected to a low-temperature plasma treatment.
  • Example 2 the sewing behavior of these two sewing threads was examined for comparison.
  • the treated material has a significantly better sewing behavior compared to the untreated comparison material, which is expressed both in a higher number when sewing buttonholes and in a significantly longer seam.
  • the tests for determining the thread break were stopped depending on the seam length at a seam length of 100 m, since no thread break occurred even after 10 sewing attempts after 100 meters.
  • Table 2 shows that with material 1 there are no differences in sewing behavior between the outer, middle and inner winding layer. In other words, these experiments clearly show that the low-temperature plasma treatment has been carried out uniformly over the thickness of the winding body.
