Definitions

  • the present invention relates to two methods for producing a sewing thread with the features of the preamble of patent claim 1 and the features of the preamble of patent claim 3.
  • Corona or low-temperature plasma treatments are already being used successfully in various fields of technology, such as plastic processing, film processing or metal processing.
  • attempts have been made to change the properties of the treated material by means of corona or low-temperature plasma treatment.
  • the main focus was on corona or low-temperature plasma treatment on endless webs of fabrics.
  • DE OS 33 12 307 describes a device or a method for low-temperature plasma treatment of tissues.
  • an endless web of fabric is rolled over from a first winding body to a second winding body, between the first and an electrode pair is arranged in the second winding body in order to generate the required low-temperature plasma.
  • a thread strand can be stretched between a first winding body and a second winding body arranged at a distance therefrom, the electrode pair for generating the low-temperature plasma also being arranged between the first and between the winding body.
  • these yarns are provided with a finishing agent to improve the sliding behavior of the yarns when sewing and thus to avoid thread breaks.
  • finishing agents In the area of surgical sewing material, however, there is a requirement that such finishing agents should not be present on the surgical sewing thread, since undesirable health risks from the finishing agents are feared here.
  • the present invention has for its object to provide a method for producing a yarn that is particularly easy to carry out with excellent sewing behavior of the yarns produced in this way.
  • a first method according to the invention provides that the fibers, filaments and / or yarns which are spun, twisted and / or swirled together to produce the sewing thread, before spinning, twisting and / or swirling a low-temperature plasma treatment or a corona Subjects treatment.
  • the low-temperature plasma treatment or the corona treatment is carried out before the actual production of the sewing thread out, so that the sewing thread is then created from the low-temperature plasma-treated or corona-treated fibers, filaments and / or yarns.
  • a sewing thread produced in this way is then processed further in a conventional manner, for example possibly dyed, dried, fixed, finished and / or rewound.
  • a particularly suitable embodiment of this first method according to the invention provides that a pile is produced from the fibers, filaments and / or yarns and a suitable gas flows through the pile during the low-temperature plasma treatment or during the corona treatment. This ensures in particular that the different layers of the pile are treated particularly evenly, so that the finished sewing thread has no different properties.
  • a finished sewing thread that has already been created and is composed of fibers, filaments and / or yarns spun, twisted and / or intermingled with one another is subjected to a corona or low-temperature plasma treatment.
  • the finished sewing thread is wound onto a winding former before the corona or low-temperature plasma treatment.
  • a suitable gas flows through the winding body and thus the sewing thread applied thereon, so that, in contrast to the prior art mentioned at the beginning, the sewing thread to be treated is not wrapped around in this second method.
  • the methods according to the invention have a number of advantages. It was thus found that the sewing threads produced by the method according to the invention are compared to sewing threads of the same construction tion, which were not subject to the previously described corona or low-temperature plasma treatments, have much better sewing properties. These are expressed, for example, by the fact that when sewing buttonholes under standard test conditions, the untreated comparison thread shows thread breaks after two to six buttonholes, while it is possible with the sewing threads produced according to the method of the invention to produce about 50 to 90 buttonholes without thread breaks. Even in sewing tests in which a normal, straight seam is created with a stitch speed of 7000 stitches per minute, the superiority of the sewing threads produced by the method according to the invention is clearly evident.
  • the methods according to the invention are particularly simple and inexpensive to use. This is compared to the beginning State of the art listed does not require that the material to be treated has to be rewound during the corona or low-temperature plasma treatment, since in the methods according to the invention these treatments are carried out on the winding body or preferably in the form of a pile. This in turn means that no malfunctions can occur in the method according to the invention.
  • the methods according to the invention can also be carried out particularly economically, since the sewing threads are in any case arranged on bobbins or opened up as piles in their manufacture or further processing or the fibers, filaments and / or yarns used for the production of the sewing threads .
  • the corona or low-temperature plasma treatment of the fibers, filaments and / or yarns or of the finished sewing thread means that the preparations which are present, for example, from primary spinning on the starting materials or applied during processing or on the surface of the sewing thread are not fixed Dye molecules are evaporated by the corona or low-temperature plasma treatment, so that a time-consuming washing out of these preparations or dye molecules can be omitted.
  • the low-temperature plasma treatment is usually carried out at a vacuum between 5 Pa and 500 Pa. Particularly good results are achieved if the low-temperature plasma treatment is carried out under a vacuum between 20 Pa and 300 Pa, preferably between 70 Pa and 200 Pa.
  • a further 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 about 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 about 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 special one Gentle treatment of the winding body or 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 is increased or decreased sinusoidally during the entire treatment.
  • 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
  • the power in the method according to the invention is between 200 W and 600 W.
  • 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.
  • 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.
  • a continuous pressure increase is carried out during the transition from the first treatment period to the second treatment period and 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 be carried out sinusoidally, whereby for the first period and the second period each treatment times between 10 seconds and 160 seconds, preferably between 20 seconds and 60 seconds, are selected.
  • the autoclave used for the corona treatment is preferably evacuated to a pressure between 1,000 Pa and 10,000 Pa, so that the respective gas which flows through the winding body or 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 133.32 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 winding body or the pile.
  • a gas which flows through the winding body or the pile This is preferably a reactive gas, that is to say a gas which, under the influence of the two gas discharges mentioned above, forms ions, highly reactive molecules, electrons and / or radicals, so that crosslinking, oxidation and / or etching may occur to bring about the surface of the fibers, filaments, yarns or the finished sewing thread.
  • a reactive gas that is to say a gas which, under the influence of the two gas discharges mentioned above, forms ions, highly reactive molecules, electrons and / or radicals, so that crosslinking, oxidation and / or etching may occur to bring about the surface of the fibers, filaments, yarns or the finished sewing thread.
  • a further embodiment variant of the method according to the invention provides that an inert gas, preferably a noble gas, a mixture of noble gases and / or nitrogen, is used as the gas instead of the aforementioned highly reactive gases. This ensures that the risk of a chemical change in the materials treated in this way is reduced.
  • an inert gas preferably a noble gas, a mixture of noble gases and / or nitrogen
  • the aforementioned reactive gases can be used in the corona or low-temperature plasma treatment. If for example fibers, filaments, yarns or finished sewing threads made of polyethylene terephthalate are flowed through during the low-temperature plasma treatment or during the corona treatment with basic, reactive gases, this means that a material treated in this way can subsequently be dyed after treatment with acid dyes. 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.
  • the total treatment time in the methods 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 density set.
  • any suitable starting material such as e.g. Use polyamide, polyester, polypropylene and / or polyacrylonitrile fibers, each alone or in a mixture with synthetic and / or natural fibers.
  • a starting material fiber, filament, thread or the finished sewing thread
  • a preparation can then be, for example, a preparation present from primary spinning or a preparation applied in the course of sewing thread production.
  • the preparation is fixed to the sewing material by the low-temperature plasma treatment or the corona treatment, forming a chemical compound, and / or the preparation is particularly evenly distributed on the surface by the gas discharge, so that the input described further improvements in properties of the material treated accordingly.
  • Polyester fibers with a staple length of 38 mm and a single fiber strength of 1.3 dtex were 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 plasma treatment: Figure 1 Duration of the first and second treatment period: 40 seconds each Total treatment time: 10 minutes 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 prior to 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.
  • the treated material 1 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.
  • a double twisted polyester thread S 900, Z1000 140 dtex x 2 was conventionally dyed and, after drying, was subjected to a low-temperature plasma treatment without aging.
  • the make-up of the polyester thread corresponded to a cross-wound winding (1 kg of material) which is customary for dyeing.
  • the finish is a hard paraffin finish, the finish being applied by direct contact with the paraffin block.
  • the first comparative material for the sewing tests a non-aged and non-low-temperature plasma-treated identical material was selected, and as the second comparative material, an identical thread, as described above, was finished after dyeing.
  • 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 plasma treatment: Figure 1 Duration of the first and second treatment period: 40 seconds each Total treatment time: 10 minutes Gas: oxygen
  • the materials were then sewn on a conventional buttonhole industrial sewing machine (Pfaff company) and the number of buttonholes counted that could be sewn without breaking the thread. Furthermore, the sewing length was determined on an industrial sewing machine, which could be achieved with 7000 stitches per minute without thread break.
  • material 1 which is also used for low-temperature plasma treatment, has excellent sewing behavior.
  • the sewing attempt was stopped after a seam length of 100 m, since even with 10 sewing attempts, which were carried out in each case from yarn lengths from the inner layer, the middle layer and the outer layer of the winding body, no thread breakage occurred after every 100 m.
  • the material 2 which was not finished, but was subjected to a low-temperature plasma treatment, shows considerably better values than the untreated, advanced reference material 2, which is expressed in the increased number of buttonholes and in the significantly longer seam length.
  • a swirled core sheath yarn produced by air extraction which was made of a polyester core material 180 dtex f 40 and a polyester effect material with 74 dtex f 24, was subjected to low-temperature plasma treatment with and without finishing agent.
  • this low-temperature plasma treatment was carried out at a power density of 8 W / dm3 and a treatment time of 15 minutes, with this embodiment also working with two 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.
  • Table 4 The results of the sewing tests on the treated and untreated comparative materials 1 and 2 can be found in Table 4 below, the block paraffin mentioned above being used as finishing agent.
  • the material 2 which was subjected to the low-temperature plasma treatment as non-advanced material was after-treated with the aforementioned block paraffin after the low-temperature plasma treatment.
  • Table 4 basically confirms the results of Table 3, with the untreated, advanced comparative material 2 already having better sewing behavior compared to comparative material 2 in Table 3. It should be emphasized that the material 2, which was subjected to the low-temperature plasma treatment in the non-activated state, showed a significantly improved sewing behavior when finished with the hard paraffin after the low-temperature plasma treatment.
  • a surgical suture was subjected to low temperature plasma treatment as in Example 4. This was also done with the addition of oxygen as a gas.
  • the residual level was determined according to DIN 54 278. After this, no avivage could be detected after the plasma treatment, while the avivage overlay before the plasma treatment was 1.2% by weight.
  • knots required until the yarn loop is torn are thus a measure of the knot strength, ie a measure of the knot sliding off the other thread. It applies here that the knot strength decreases with increasing number of knots, with the result that the surgeon has to make a corresponding number of knots to secure the surgical suture, which is time-consuming and undesirable.
  • the loops in material 1 already break when they are provided with one or two knots, while four to six knots are required with the corresponding comparison material. This means that the knot strength of the treated material (material 1) is much better, so that only one or two knots are required for surgical interventions to secure the corresponding surgical suture.
