Definitions

  • the invention relates to a highly elastic fabric having an elastic elongation of at least 200% in the direction of the courses and at least 150% in the direction of the wales measured with a force of 10 N and which has a basis weight of at most 220g / m 2 , wherein at least every second Mesh of the knitted fabric is formed by a yarn having a wound with at least one polyamide thread elastane thread and further at least one cellulosic thread.
  • An elastane thread that is doubly wound by means of a winder is also shown in DE 40 27 279 A1.
  • the elastane thread runs between a spool and a delivery mechanism, which pulls the elastane thread from the spool and the a Aufwickelstelle is connected downstream. Between the coil and the delivery mechanism the thread runs through two consecutively arranged rotating hollow spindles, the disc coils with the supply of each thread to be wrapped wear.
  • the inner cover thread of the taught in DE 40 27 279 A1 combination yarn is made of a soluble, for example PVA-hot water-soluble thread and the outer wrapping thread is made of a textile thread, for example viscose, Polyamide or polyester formed.
  • An elastic core thread is combined with one or passed several sheath threads through a Umwirbelungsdüse and vortexed.
  • Sheath thread can be made, for example, of polyester, polyamide, viscose filament yarn, Cotton or a combination of several yarns. That with the Mantle thread umspun elastane yarn is subsequently through a hollow spindle led and wound by another mantle thread. It can here the Same sheath threads as for the reeled sheath thread or other sheath threads be used.
  • a knitted fabric of the type mentioned is apparent from DE 195 06 227 A1.
  • a knitted fabric or knitted fabric is known from a yarn, which has a central textile thread and at least one cellulose triacetate thread which is wound around the textile thread.
  • a textile thread is preferably a nylon thread or an elastic polyurethane thread, so elastane thread intended.
  • the central textile thread double wound.
  • the first sheath can, for example, of a Nylon thread or polyamide thread and the second sheath of a cellulose triacetate thread be formed. In such a double wrap, the conventionally takes place in a single production step, have the two Umwindungsfäden different directions of rotation to the central thread on.
  • a wrap around with a natural yarn such as a cellulose triacetate thread is by means of a conventional wrapping machine but hardly possible, since such natural yarns do not have the associated burden can withstand and tear.
  • the usual rotation speed of a Spindle of a wrapping machine is in the range of 20,000 revolutions per minute. The production of such a yarn is therefore in the industrial Mass production practically impossible and such a yarn has no collection found in practice.
  • the object of the invention is to provide a highly elastic knitted fabric of the aforementioned To provide type, with a thin training and a good durability as well as a pleasant wearing comfort a high vegetable natural fiber portion having. This is achieved by a knit with the invention Features of claim 1.
  • viscose or cotton may be used as the cellulosic thread become. Conceivable and possible would be the use of other threads made of cellulosic fibers such as linen, flax, hemp or jute. All such cellulosic fibers are referred to in this document as "natural plant fibers" designated. These cellulosic fibers may be staple fibers or continuous fibers.
  • the number of revolutions of the sheath yarn produced in Umwindemaschinen is usually significantly higher than the twisting produced by a twisting machine.
  • the number of revolutions of the polyamide around the elastane in the range between 1,500 and 2,000 revolutions per meter and the twisting of the thread between the wound elastane thread and the cellulosic thread in the area between 250 and 450 revolutions per meter.
  • Fig. 1 is shown as a knitted fabric 1, for example, a shirt. Further preferred Exemplary embodiments of the knitted fabric are fine stockings and tights, Underwear, bodysuits, leggings etc.
  • FIG. 1 In particular on a single-cylinder circular knitting machine produced right-left knitted fabric are shown in FIG There are 2 rows of stitches, at least every other row of stitches is formed of an elastic yarn 3. Intermediate rows of stitches may be formed of an inelastic polyamide yarn. It but all courses 2 may consist of an elastic yarn, whereby a particularly high elasticity of the knitted fabric 1 can be achieved.
  • the elastic elongation of the knitted fabric is at least 200% in the transverse direction, ie in the direction of the courses 2, and at least 150% in the longitudinal direction, ie in the direction of the wales 7, measured with a force of 10 N.
  • a knitted fabric according to the invention is made relatively thin and has a basis weight of at most 220 g / m 2 .
  • the knitted fabric can be made transparent, in particular in the fine-stocking region, a highly transparent formation of the knitted fabric is preferred.
  • the elastic yarn 3 shown schematically in FIG. 3 has an elastane thread 4 on.
  • elastane threads or elastic polyurethane threads are in Trading among other things under the designation Lycra or Dorlastan offered.
  • the elastane thread is by means of a Umwindemaschine, in a conventional manner can be formed, wound by a polyamide thread 5, wherein the Umwindungsiere or number of revolutions in the range between 800 and 3,000 revolutions per meter.
  • a preferred range of the number of revolutions is between 1 000 and 2 500 revolutions per meter.
  • the wrapped with the polyamide thread 5 Elastanfaden 4 and a cellulosic Thread 6 are twisted together by means of a twisting machine.
  • a twisting machine A usual Embodiment of a twisting machine is in particular the ring twisting machine, which corresponds to a ring spinning machine without upstream drafting.
  • the Twist rotation is a maximum of 1 000 revolutions per meter, with an area between 200 and 800 revolutions per meter is preferred.
  • a particularly preferred Range for which good experimental results have been achieved lies between 250 and 450 revolutions per meter.
  • this yarn 3 thus takes place in a two-stage production process, namely by winding on a belt and then by twisting on a twisting machine.
  • the direction of rotation of the polyamide thread around the elastane thread and the direction of rotation between the cellulosic thread and the elastane thread wrapped with the polyamide thread can be the same or opposite.
  • the titer of the elastane thread is, for example, in the support laundry area maximum 105 dtex. In fine hosiery and laundry applications, the titer of the Elastane thread at a maximum of 44 dtex.
  • An inventive knit can advantageously also have a very low titer of the elastane thread, the for example, at 10 dtex or 8 dtex.
  • the titer of the polyamide thread is in the laundry preferably at maximum 150 dtex, in the fine stocking area at a maximum of 78 dtex, while the titer the cellulose thread in the laundry area at preferably at most 150 dtex and in the fine stocking range is a maximum of 100 dtex.
  • the polyamide thread 5 and the existing of a cellulosic fiber thread. 6 are preferably multifilament, although a monofilament design in principle conceivable and possible.
  • the elastane thread 4 is stretched in the yarn 3, for example, by a factor of at least 1.5. This factor can also are higher, for example in the range between 2 and 4.
  • the elastane yarn has 17 dtex, the polyamide yarn 11 dtex and the cellulosic thread 33 dtex.
  • a cellulosic thread For example, cupro, a viscous-like material can be used.
