Definitions

  • the invention relates to a thread, in particular a sewing thread at least one raw yarn that is at least made by air texturing a roving made of single filaments or single fibers is, and a method for producing air-textured threads.
  • An object of the invention is to create an air textured thread is as simple as possible to produce and at the same time as possible has high strength, and a method for producing such To create thread.
  • the raw yarn forming the thread does not twist itself on.
  • the raw yarn therefore needs to produce the thread not twisted, i.e. not provided with its own twist become.
  • An addresss to the air texturing for the production of the raw yarn can be according to the invention thus eliminated. This will produce the raw yarn formed thread considerably simplified.
  • the thread according to the invention has optimum strength on, and also with regard to the other properties of the thread, which at the processing of which is important, has the invention Thread turned out to be advantageous. So the invention Thread in spite of the fact that the raw yarn is not twisted when Sew well, and the thread according to the invention shows a total calm behavior during its processing. Furthermore draws the thread according to the invention is characterized by a slight tendency to crimp out.
  • the thread consist of exactly one raw yarn. Apart from one in Connection to its manufacturing equipment of air-textured Raw yarn is the only untwisted raw yarn itself Thread, which is therefore a thread without twisting is.
  • the thread it is also possible for the thread to consist of several in particular consists of two, three or four rovings, each of which none Have self-twisting and in an untwisted state Formation of the thread can be air-textured with one another.
  • the thread in an alternative of the invention it is possible for the thread to be made of several rovings exist, of which only a part each none Has self-twisting, while the other rovings before formation of the thread can be twisted.
  • Single filaments or single fibers have an average fineness between 1.6 and 2.0 dtex, preferably between about 1.7 and 1.9 dtex and particularly preferably have about 1.8 dtex.
  • the individual filaments in the air-textured raw yarn without finishing or single fibers an average fineness of less than about 1.2 dtex.
  • This previously unattainable fineness of the individual reinforcements (filaments and / or fibers) in the thread has the advantageous result that an inventive thread in Compared to previously produced threads with the same fineness and strength of the thread a larger number of single filaments or single fibers owns and is therefore much softer.
  • At least part of the individual filaments or individual fibers is preferred in the form of microfilaments or microfibers with a basic fineness in Raw yarn of less than about 1.2 dtex each, especially less than about 1.0 dtex is provided.
  • the raw yarn and thus the one from the The roving (s) formed is thus created by air texturing with microfilaments and / or microfibers, i.e. with individual reinforcements, each finer than 1.2 dtex and in particular finer than 1.0 dtex are.
  • the air-textured raw yarn and thus the air-textured thread according to the invention thus has a micro portion in this embodiment, i.e. a proportion of microfilaments or microfibers. According to the invention can the raw yarn and thus the thread exclusively from such Micro strength members exist.
  • Thread a label number greater than about No 100 or a fineness less than about 300 dtex.
  • a thread according to the invention which has a label number of approximately No 100 or has a fineness of about 300 dtex or is finer, is suitable especially for use in connection with e.g. Men's and women's clothing, Linen and swimwear, protective work clothing, Leisure clothing, home textiles, leather clothing, small leather goods, Sportswear as well as tents and is for use on sewing machines, Sewing machines or embroidery machines ideally suited.
  • the object underlying the invention is, on the other hand, by a Process with the features of the independent process claim and in particular solved in that at least one air-textured Raw yarn is produced in which the individual filaments are not equipped or single fibers an average fineness of less than about 3.0 dtex, the air-textured raw yarn in an untwisted Condition is processed to form the thread.
  • an air-textured is thus used to produce the thread Raw yarn used without twisting. Because the air textured Raw yarn after twisting is not twisted needs to be provided, the production of the thread becomes significant simplified.
  • the thread is made from exactly one untwisted raw yarn becomes.
  • the thread it is also possible for the thread to consist of several is produced in particular from two, three or four rovings.
  • the figure shows in the left part two rovings 11, one of which in the Production of a raw yarn 19 shown in the right part by a Air texturing process as upright thread 13 and the other as effect thread 15 serves.
  • Both rovings 11 each consist of individual reinforcements 17a, 17b, and that from endless individual filaments, sometimes called Individual fibers are referred to, although generally referred to as "fibers" are meant by finite length, e.g. from single filaments can be made by tearing or cutting.
  • fibers Preferably there is both the upright thread 13 and the effect thread 15 from individual plastic filaments, regenerated fibers and / or natural fibers 17a, 17b.
  • the number of reinforcements 17a, 17b in the roving 11 can be used both for the upright thread 13 as well as for the effect thread 15 in the range from 24 to 400 lie.
  • the upright thread 13 is preferably in the form of a LOY (low oriented yarn), POY (partial oriented yarn), FOY (full oriented yarn) or an FDY (fully drawn yarn) provided.
  • the roving forming the effect thread 15 11 is preferably a POY or LOY.
  • the average fineness of the individual strength members 17a, 17b in Raw yarn is less than about 3.0 dtex.
  • Particularly advantageous in particular regarding the sewing properties has an average Fineness of about 1.8 dtex is highlighted.
  • the air-textured raw yarn can also have an average fineness of Have single filaments or single fibers of less than about 1.2 dtex.
  • the individual strength members 17a, 17b can at least partially be provided as microfilaments or microfibers that have a basic fineness in the raw yarn 19 each less than about 1.2 dtex and in particular less than about 1.0 dtex.
  • the air-textured raw yarn 19 also by air texturing only a single roving can be produced, resulting in a Differentiation in roving between stand thread and effect thread unnecessary. Alternatively, however, several upright threads and / or several effect threads can be used.
  • the thread If the thread is made from exactly one roving 11, then the thread consequently consists of only one untwisted one Raw yarn 19, i.e. the thread has no twisting. It can the raw yarn 19, if necessary, basically after its manufacture be equipped in any way to make the final To form thread.
