Definitions

  • the invention relates to a knitted fabric of the type specified in the preamble of claim 1 and to a method and a device for the production thereof in accordance with the preambles of claims 6 and 16.
  • All known knitted fabrics of the type mentioned have in common that they have or require at least one basic knitted fabric made of thread material.
  • the character of a knitted fabric is essentially shaped by the type of thread material used and the binding provided in the basic knitted fabric in the individual case.
  • For knitwear in the clothing sector there are also special requirements for wear properties, such as water absorption, softness or pliability.
  • thread material here includes all thread-like materials that consist of one or more elongated or endless threads.
  • the comfort of a knitted garment increases with its softness.
  • knitwear produced to date which are made with thread materials consisting of yarns that predominantly contain natural staple fibers or mixtures thereof with man-made fibers
  • the softness of the knitted fabrics largely depends on the yarn structure and the spinning process used to produce it.
  • the purpose of the spinning process is to arrange the staple fibers together by giving them a twist so that a yarn is formed, the essential feature of which is the absorption of tensile forces.
  • Extremely soft knitted fabrics can neither be made from classic king yarns nor from so-called unconventional yarns such as rotor yarns, bundle yarns or wrapping yarns, since games always have twists and bundles that lead to a noticeable stiffness in the knitted fabric.
  • classic ring yarn provides mesh structures 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 lining or plush threads (DE 28 04 068 AI, DE 197 07 053 AI) are incorporated into a basic knitted fabric or the yarns or knitted fabrics are specially equipped. '
  • the invention has set itself the task of shortening the production process and creating comfort-improving knitted fabrics based on staple fibers, with which the handle - even without plush or lining threads, without the integration of additional tufts of fibers and without special equipment od ... - Is extremely soft.
  • the object of the invention is to propose methods and devices for producing such knitted fabrics.
  • the thread material in the knitwear initially described is characterized in that it contains a continuous fiber structure in which the staple fibers are almost untwisted and arranged essentially parallel to one another.
  • the inventive method and the inventive device are characterized by the features of claims 6 and 16.
  • the knitted fabric according to the invention consists of a thread material that is not a yarn. Rather, the thread material according to the invention contains a fiber structure which is formed from untwisted and essentially parallel staple fibers. This gives a knitted fabric with extreme softness.
  • a stitch-forming thread for the knitted fabric according to the invention is produced from two components, namely the fiber structure according to the invention and an auxiliary thread that runs preferably parallel and untwisted to this.
  • the auxiliary thread can be a mono- or multifilament, whereby the multifilament can also be provided with real protective twists. Regardless of this, the auxiliary thread is appropriately such chosen that the character of the knitted fabric is predominantly characterized by the component consisting of the fiber structure.
  • the method and the device according to the invention preferably assume that a fiber structure designed in the manner of a fuse is stretched to the desired fineness in a drafting system prior to stitch formation and then processed directly into stitches or after a pretreatment appropriate for knitting reasons.
  • the latter can be done, for example, with a flat or circular knitting machine, which can be designed as a right / right, right / left or left / left circular knitting machine. Based on this, various variants are proposed according to the invention.
  • the knitting machine designed as a small circular knitting machine, which z. B. suitable for the production of tubular goods for dressing material, the fiber dressing is expediently fed to a knitting point located in the immediate vicinity after leaving the drafting unit and immediately processed into stitches in this.
  • a second variant according to the invention is present when the staple fibers emerging from the drafting system arrive as a fiber structure in a spinning device, in which they are spun into an unconventional yarn (e.g. bundle yarn or winding yarn). This solidifies the fiber structure so that it can be transported to the knitting point of a circular knitting machine over greater distances. However, it is not a question of achieving maximum tensile strength, but of maintaining the desired soft grip.
  • an unconventional yarn e.g. bundle yarn or winding yarn
  • the fiber stream emerging from the drafting device is spun by a twist element to form a temporary, genuinely twisted classic yarn, which, for. B. rotates in a spinning tube and is transported through this to a knitting point or to a thread guide assigned to the knitting point.
  • a soft grip arises because the real twists on the short distance between the thread guide or the end of a spinning tube and the knitting point can be resolved by the false wire effect.
  • the knitted fabric obtained is then extremely soft and pleasant to the touch.
  • a further variant provides that in addition to the fiber structure, an auxiliary thread runs in at the knitting point.
  • the auxiliary thread is preferably fed in before the pair of output rollers of the drafting system. He goes through the pair of exit rollers and takes part in the process of forming 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 feel, in particular because there are no twists between the auxiliary thread and the fiber stream, i. H. Run the fiber dressing and auxiliary thread in the stitches in parallel.

  • a stitch 1 of a knitted fabric of a known type is shown. It consists of a thread material 2 and has the usual, for. B. for a right / left knitwear typical binding points 3.
  • FIG. 2 shows a thread material 4 according to the invention which is suitable for producing the knitted fabric according to FIG. 1. It consists of a thread in the form of a continuous or, like a conventional thread, endless fiber structure 5, which is formed by staple fibers 6, which are untwisted and largely parallel to the longitudinal extension of the thread material 4.
  • the fiber structure 5 according to FIG. 2 has no strength per se. Surprisingly, however, it has been shown that the fiber structure 5 is given sufficient strength, in particular tensile strength, by the binding groove ⁇ 3 within a stitch 1, and is thus used for the production of knitted fabrics such. B. of knitted garments is well suited.
  • Thread material 7 is used, which consists of a combination of the fiber structure 5 and an endless auxiliary thread 8 (Fig. 3).
  • the character of the thread material 7 is expediently shaped here by the staple fiber association 5. This applies in particular if the fiber structure 5 / auxiliary thread 8 dominates the fiber structure 5 in the mass ratio. 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 consist, for example, of a monofilament (FIG. 3) or of a multifilament 9 (FIG. 4).
  • the return torque in the knitted fabric is virtually zero when using the fiber structure 5 or, in the case of combinations of fiber structure 5 / auxiliary thread 9, virtually zero.
  • the stitch legs of stitch 1 therefore do not appear crooked, but completely symmetrical.

  • the fiber structure 5 according to FIG. 2 in contrast to, for example, high pile goods, forms a continuous (endless) thread which is used for forming the machine and z. B. can serve the production of a conventional basic knitted fabric in the form of a smooth right / left knitted fabric.
  • the use of other weave patterns is also possible, as is the case with yarns.
  • Both long-staple fibers (e.g. wool) and short-staple fibers (e.g. cotton) as well as fibers made of other than textile materials, e.g. B. metal or plastic fibers are used.
  • Devices can be used according to the invention to produce a knitted fabric with the thread material 4 or 7 described, which are explained in more detail below with reference to FIGS. 5 to 13 and can be referred to as spinning knitting devices, for example.
  • FIG 5 shows the invention using the example of a circular knitting machine with a needle zy linder 11 of very small diameter (eg 1 ").
