Definitions

  • the invention relates to an air-textured thread and a method for Production of air-textured threads.
  • EP 0892097 A2 describes a method for producing air-textured Known sewing threads. Those which can be produced by this known method Threads are not optimal in certain applications Properties on.
  • An object of the invention is an air-textured thread that is as possible is fine and / or soft and at the same time the highest possible strength has, and a method for producing such a thread to accomplish.
  • the thread consists of at least one raw yarn, which is made by air texturing at least one consisting of individual filaments or individual fibers Roving is made, being in the air-textured raw yarn without equipment the single filaments or single fibers an average Have a fineness of less than about 1.2 dtex.
  • the thread according to the invention consequently consists of at least one raw yarn, which is made by air texturing and in which not equipped condition, the average fineness of the individual filaments or single fibers is less than 1.2 dtex. So far neither in Spinning process still achievable by air texturing average Fineness of the individual strength members (filaments and / or fibers) in the thread advantageously has the result that an inventive Thread compared to previously produced threads with the same fineness and strength of the thread a larger number of single filaments or Owns single fibers. Due to the high number of individual strength members is the thread according to the invention compared to previously produced Threads much softer with the same fineness and strength.
  • the Thread according to the invention is consequently particularly advantageous in such Areas of application, e.g.
  • the invention therefore makes it possible to determine the number of individual strength members increase in the thread and thus a softer thread too create without disadvantages in terms of fineness and strength to have to accept.
  • Thread according to the invention Another advantage of the thread according to the invention is its essential better maneuverability when sewing.
  • the invention shows Thread a generally calmer behavior during its processing.
  • the thread according to the invention is characterized by a less tendency to squeeze out.
  • Seams created by threading also have less impact less noticeable and lead to significantly less pronounced Seam impression especially when ironing.
  • the invention needs Thread to be twisted less than conventional ones Threads to achieve optimal sewing or processing properties.
  • At least part of the individual filaments or individual fibers is preferred in the form of microfilaments or microfibers with a basic fineness of each less than about 1.2 dtex, in particular less than about 1.0 dtex intended.
  • the air-textured raw yarn is at least partially made of microfilaments or microfibers, each with a basic fineness less than about 1.2 dtex, especially less than about 1.0 dtex.
  • the raw yarn and thus the thread formed from the raw yarn is created here by air texturing with microfilaments and / or Microfibers, i.e. with single or basic strength members that are finer than 1.2 dtex and in particular finer than 1.0 dtex.
  • the air textured raw yarn and thus the air textured thread according to the In this embodiment, the invention thus has a micro fraction, i.e. one Share of microfilaments or microfibers.
  • the raw yarn and thus the thread exclusively from such micro strength supports consist.
  • the number of individual filaments or individual fibers in the roving is preferred approximately in the range of 24 to 400.

  • the raw yarn consists of several rovings and in particular at least one stand thread and at least one effect thread.
  • the upright thread preferably has an initial fineness in the undrawn direction Condition in the range of about 50 to 300 dtex.
  • the effect thread preferably has an initial fineness in the undrawn state in the range of 50 to 300 dtex.
  • the effect thread is as fine as or finer than the upright thread.
  • the individual filaments are or individual fibers of the effect thread as fine as or finer than those of the thread.
  • the roving can be of circular cross section or basically have any profile. Furthermore, the roving be glossy or in principle have any matting. In addition, the air-textured raw yarn can follow Manufacturing basically be equipped in any way if necessary before or after twisting with one or more others Raw yarns.
  • 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 from at least one roving, the consists of individual filaments or individual fibers, at least one of which Part in the form of microfilaments or microfibers with a basic fineness each less than about 1.2 dtex, especially less than about 1.0 dtex is provided, at least one air-textured raw yarn is produced is in which the single filaments or single fibers without equipment have average fineness less than about 1.2 dtex.
  • microfilaments are thus made in an air texturing process and / or microfibers, each having a basic fineness or Initial fineness of less than about 1.2 dtex, especially less than have about 1.0 dtex.
  • a particularly soft, air-textured raw yarn and thus a through advantageous softness distinguishing air-textured thread created be, which still has a high strength.
