Definitions

  • the invention relates to a method and an apparatus of the genera specified in the preambles of claims 1 and 9.
  • Knitwear of the type of interest here in particular those which are produced on a circular knitting machine, has in common that they have or require at least one basic knitted fabric made of thread material.
  • the character of such a knit fabric is essentially characterized by the type of thread material used and the provided in each case binding within the base knit.
  • For knitwear of the garment sector also have special requirements for wearing properties such as water absorption, softness or pliability.
  • thread material here includes all commercially available yarns, which consist of one or more, elongated or endless thread.
  • the comfort of a knit garment increases with its softness.
  • knitwear of all types produced to date which are made from yarns containing predominantly natural staple fibers or blends thereof with man-made fibers
  • the softness of the fabrics largely depends on the yarn structure and the spinning process used to make it.
  • the purpose of the spinning process is to arrange the staple fibers together by imparting rotation so as to form a yarn whose essential feature is the absorption of tensile forces.
  • Extremely soft knits can be made neither from traditional ring yarns nor from so-called unconventional yarns such as rotor yarns, bundle yarns or wraps because yarns always have twists and bundles, which leads to a noticeable stiffness in the fabric. At most classic Ringgam provides mesh with pleasant wearing properties. The desire for extremely soft knitwear can therefore not be met with the known types of yarn. This also applies if, in order to achieve special properties, additional feed or plush threads ( DE 28 04 068 A1 . DE 197 07 053 A1 ) embedded in a basic knit or the yarns or knitted fabrics are equipped in a special way.
  • a very similar purpose is served by other known methods and devices ( GB-A-1 538 924 ), by means of which staple fibers are processed into a cord or cord-like thread material.
  • an endless sliver is first stretched in a drafting and then fed to a stationary needle cylinder in which two to four knitting needles are mounted movable up and down to produce this with the type of warp knitting a consisting of one or two wales yarn.
  • the invention has the object to shorten the production process and to provide a method and an apparatus for producing a comfort-enhancing knitwear based on staple fibers, the handle without the use of special thread materials or plush or lining threads, without the integration of additional tufts and without special equipment od.
  • the handle without the use of special thread materials or plush or lining threads, without the integration of additional tufts and without special equipment od.
  • the handle without the use of special thread materials or plush or lining threads, without the integration of additional tufts and without special equipment od.
  • An essential feature of the method and apparatuses according to the invention is that the knitting machine is not supplied with a customary yarn or yarn or the like described in the introduction, but a fiber structure consisting of untwisted staple fibers arranged parallel to one another and immediately before entry into the knitting point, d. H. produced on the knitting machine itself.
  • An essential feature of the knitwear produced by the methods and devices according to the invention is that they consist of a thread material which is not yarn. Rather, the knitwear according to the invention are made directly from a fiber structure, which is formed from untwisted and substantially parallel staple fibers. This results in a knit fabric with extreme softness.
  • a stitch-forming thread for the knitwear according to the invention is made of two components, namely the fiber structure according to the invention and a preferably parallel and untwisted to this ongoing auxiliary thread.
  • the auxiliary thread can be a monofilament or multifilament, wherein the multifilament can also be provided with real protective rotations. Regardless, the auxiliary thread is expediently chosen such that the character of the knitwear is predominantly characterized by the component consisting of the fiber structure.
  • the inventive method and the device according to the invention are preferably based on stretching a fiber structure formed in the manner of a sliver before the stitch formation in a drafting to the desired fineness and then to process directly or after a suitable for knitting technical reasons pretreatment to mesh.
  • the latter can be done, for example, with a flat or circular knitting machine, which can be configured as a right / right, right / left or left / left circular knitting machine. Issuing this, various variants are proposed according to the invention.
  • a first variant according to the invention is present when the staple fibers emerging from the drafting system arrive in a spinning device as fiber structure in which they are spun into an unconventional yarn (eg bundle yarn or cover yarn).
  • the fiber structure is solidified in order to be able to transport it over long distances to the knitting point of a circular knitting machine.
  • it does not depend on the achievement of a maximum tensile strength, but on the maintenance of the desired soft grip.
  • auxiliary thread runs in at the knitting point.
  • the auxiliary thread is preferably fed in front of the pair of delivery rollers of the drafting system. He goes through the exit roller pair and participates in the formation process of the temporary yarn.
  • the combined thread material consisting of the fiber stream and the auxiliary thread forms stitches, which in turn have an extremely soft hand, in particular because there are no twists between the auxiliary thread and the fiber stream, ie. H. Fiber structure and auxiliary thread parallel in the stitches.
  • a mesh 1 of a knitted fabric of known type is shown. It consists of a thread material 2 and has the usual, z. B. for a right / left knit fabric typical binding points 3.
  • Fig. 2 is an inventive, according to the manufacture of knitwear Fig. 1 suitable thread material 4 is shown. It consists of a thread in the form of a continuous or a like a conventional thread endlessly produced fiber structure 5, which is formed by staple fibers 6, which are undiluted and substantially parallel to the longitudinal extent of the thread material 4.
  • the fiber structure 5 after Fig. 2 has no strength in itself. Surprisingly, however, it has been shown that the fiber structure 5 is obtained by the indentation points 3 within a mesh 1 sufficient strength, in particular tensile strength and thereby for the production of knitted fabrics such. B. of knitted garments is well suited.
  • the staple fibers become jammed in the bonding points 3 and absorb force via the frictional engagement.
  • the stitches 1 and the knitted fabric formed from them are then as strong as a knitted fabric made of yarn.
  • An important difference for the invention lies in the softness of the handle.
  • the handle of a knitwear, which consists of thread material 4, which in turn is formed from a fiber structure 5, is unsurpassed soft.
  • a similar, although not so soft handle is achieved when a thread material 7 is used, which consists of a combination of the fiber structure 5 and an endless auxiliary thread 8 (FIG. Fig. 3 ) consists.
  • the character of the thread material 7 is expediently also embossed here by the staple fiber strand 5. This is especially true when the fiber structure 5 dominates in the mass ratio fiber structure 5 / auxiliary thread 8. Particularly good properties are achieved with a mass distribution of, for example, 70% fiber structure 5/30% auxiliary thread 8.
  • the auxiliary thread 8 can for example consist of a monofilament ( Fig. 3 ) or from a multifilament 9 ( Fig. 4 ) consist. Also conceivable are combinations of the fiber structure according to the invention with an auxiliary thread 8 in the form of a yarn of staple fibers, for. As a ring yarn, rotor yarn, bundle yarn or Umwindegarns, etc., but in this case, the mass ratio fiber strand 5 / auxiliary thread 8 should preferably be sufficiently large so that the desired soft handle of the knitwear according to the invention is not affected by the auxiliary thread 8 and 9 respectively. Because all knits 1 with a fiber structure 5 as described above should be distinguished by a particularly soft handle according to the invention, which significantly differs from the handle of knitwear made of yarns.
  • the return torque in the knitted fabric is zero when using the fiber structure 5 or virtually zero for combinations of fiber structure 5 / auxiliary thread 9.
  • the mesh legs of mesh 1 therefore do not appear crooked, but completely symmetrical.
  • the method of preparation for the fiber structure 5 according to the invention can in principle be chosen freely.
  • One possible production is z. B. in that the cross sections of slivers (Lunten), the od of a drafting. Like. Come, be reduced by applying further drafting to a suitable value for knitting. Under a "sliver" is coarse, not twisted and od in cans. Like. Well-held sliver understood.
  • the fiber composites 5 can also be produced from card slivers and brought to the desired final fineness with draw frames.
  • the fiber structure 5 after Fig. 2 forms a continuous (endless) thread that is used for stitching and z.
  • the production of a standard base knit in the form of a smooth right / left knit fabric can serve.
  • the application of other weave patterns is possible as with the use of yarns.
  • Both long staple fibers (eg wool) and short staple fibers (eg cotton) as well as fibers from other than textile materials, eg. As metal or plastic fibers are used.
  • a knitted fabric with the described thread material 4 or 7 can serve according to the invention devices, which are described below with reference to Fig. 5 to 13 be explained in more detail and may be referred to, for example, as a spun-knit devices.
  • Fig. 5 shows the invention using the example of a circular knitting machine with a needle cylinder 11 of very small diameter (eg 1 ") .
  • This circular knitting machine is particularly suitable for the processing of long staple fibers and for the production of knitwear which can be used, for example, as a dressing material Fig. 5 serves as a thread material 4 according to a fiber structure Fig. 2 , which is continuously fed from conventional output rollers 12 of a schematically indicated by the reference numeral 14 drafting a yarn guide 15.
  • the thread material 4 consists of the untwisted and substantially parallel fibers 6 accordingly Fig. 2 and is processed immediately after its production in the drafting system 14, ie without intervening winding process to mesh.
  • the yarn guide 15 leads the yarn material 4 to a schematically indicated knitting point 16, at which it is driven by expelled knitting needles 17, z.
  • knitting needles 17, z As usual latch needles, which are slidably mounted in grooves of the needle cylinder 11, recorded and analogous to Fig. 1 is processed into stitches.

  • the distance of the thread guide 15 of the needles 17 is only a few millimeters.
  • the stitch formation is made possible by the fact that the thread material 4 is first sucked by the suction 18 and placed radially to the needle cylinder axis and stretched so that it detected by the knitting point 16 in a thread receiving position raised knitting needles 17 and their deduction in the Maschen Strukturs- or .Making position can be processed into stitches.

This allows the distance from a last in the direction of the circular knitting machine, formed by the réelleriemchen 19 terminal point 20 for the fiber strand 4 to the thread guide 15 and a stitch formation (Kulierstelle) very small and especially the same or smaller than the staple length of the fibers 6, as required for proper stitch formation.
  • the device knits a very soft and also cheap knit, because the actual spinning process is eliminated.
  • FIGS. 5 and 6 knitting with a fiber material 4 after Fig. 2 show, the embodiment is after Fig. 7 directed to a device for processing a thread material 21, which is referred to as unconventional yarn.
  • An unconventional yarn is understood by a person skilled in the art to be a yarn which has twists that deviate from classical rotations, such as those arising in ring or selfactor spinning.
  • An advantage of such a thread material 21 is in particular that after it in comparison with the fiber material 4 after Fig. 2 an increased tensile strength can be given.
  • the thread material 21 is then suitable for being transported over greater distances, as is generally desired in large circular knitting machines (needle cylinder diameter eg 30 "or more) or at least in circular knitting machines whose needle cylinders have larger diameters than those based on the FIGS. 5 and 6 have described micro-circular knitting machines. With the thread material 21, it is possible to choose the distance between the output rollers 12 of the drafting system 14 and the knitting point 16 larger than in FIGS. 5 and 6 is indicated.
  • the Fig. 7 shows a section through the knitting point 16 of a circular knitting machine for the processing of short staple fibers by means of spinning devices of known type. Between the drafting 12 and the knitting point 16 is for spinning a unconventional yarn 21 certain spinning member 22, of which the yarn 21 in a tube 23rd is directed to a yarn guide 24, here through the outlet end of the tube 23 is formed.

  • the production is cheaper, because this knitting process in comparison to the classic approach, a shortening occurs because the coils is eliminated.
  • the embodiment according to Fig. 8 relates to a device by means of which first a "temporary" yarn 25 is produced.
