Definitions

  • the present invention relates to a knitted part, in particular to a compressive knitted part with an adhesive effect, according to the preamble of claim 1.
  • Knitted parts of this type are used, in particular for the formation of leg clothing, for medical use and/or for use in sporting activities. These compressive garments are used to apply pressure to a patient's body in a targeted manner. The pressure exerted on a patient's body is called compression.
  • the aim of compression stockings for example, in particular in the form of leggings with or without hand or foot sections for medical use, is, among other things, to relieve a patient's damaged venous and/or lymphatic system.
  • the pressure applied prevents increasing swelling of the limbs, improves the evacuation of venous blood and lymph and increases blood supply. When using compression stockings in sports, they increase performance and improve regeneration.
  • these compressive knitted parts are preferably knitted flat or circularly using a circular knitting machine or a flat knitting machine having a front and a rear needle bed.
  • the knitted parts are knitted from at least one stitch-forming knitting thread and an inserted elastic weft thread.
  • the standard RAL-GZ 387 of the Quality Mark Association exists for the production, in particular for the measurement and quality assurance, of compressive arm or leg stockings for medical use.
  • the RAL test regulations show how the pressure of a compression stocking on a leg is to be determined. Testing on the HOSY measuring device (Hohenstein Institute) is suggested as a measuring device, in particular a compression test device.
  • the test is carried out by measuring the tension force in the several measuring points, which varies depending on the respective extensibility of the knitted fabric, i.e. depending on the elasticity of the knitted fabric.
  • the compression is calculated from the clamping force. This means that the more elasticity a knitted fabric has in the transverse direction of the knitted fabric, the lower the compression exerted on the patient by the knitted fabric. On the other hand, the lower the elasticity of the knitted part, the higher the compression exerted on the patient.
  • a large number of compressive knitted parts, in particular in the form of arm or leg stockings, are known from the prior art.
  • a textile fabric with an anti-slip effect, in particular for use in bandages or compression stockings, is, for example, from EP 2 886 691 B1 known.
  • This well-known textile fabric which is a flat knitted fabric made with a double formation, is produced using two thread systems which are connected to one another by forming stitches with a stitch head and two stitch legs leading to the stitch head.
  • An anti-slip effect is given to the fabric by the fact that a silicone thread is knitted into the textile fabric to form a stitch, namely in such a way that the silicone thread forms basic knitting stitches and is therefore essentially only exposed on the surface of the textile fabric in the area of its loop legs.
  • the silicone thread occurs only in the area of the loop legs on the surface of the fabric or protrudes from it.
  • a major part of the silicone mesh is inside the knitted fabric.
  • a disadvantage of the design of the textile fabric known from this prior art is the reduced adhesive effect. Due to the fact that the adhesive silicone thread knitted into the textile fabric to form a stitch only protrudes from the knitted fabric surface on its loop legs, there are only very few adhesive sections on the fabric. The predominant part of the silicone thread, namely the stitch heads and stitch feet, is present inside the knitted fabric, ie neither on the inside nor on the outside of the knitted fabric. This proportion of the knitted-in silicone thread, in particular the stitches formed in each case, has no effect on the adhesive properties of the knitted fabric. On the contrary, this proportion reduces the breathability of the knitted fabric, which in turn can lead to increased perspiration in the wearer of the garment.
  • a further disadvantage of the textile fabric known from the prior art is the formation of the basic knitted fabric as a flat knitted fabric, in particular using the silicone thread to form basic knitted stitches. Due to the formation of the fabric as a flat knitted fabric, in particular as a two-layer knitted fabric, the silicone thread only occurs a surface of the fabric. An anti-slip effect is therefore only given on one side of the knitted fabric. For knitted fabrics or compressive items of clothing, however, where a slip-resistant effect is to be provided on both sides of the fabric, this prior art does not provide any proposed solution.
  • a textile fabric in particular a knitted fabric, known, which has an inside and outside, on each of which in turn Adhesive portions are provided to create an adhesive effect simultaneously between the support of the fabric and the fabric itself and between the fabric and an external surface.
  • the adhesive sections are made of a sticky and structured material.
  • it is proposed to knit the entire textile fabric from several adhesive yarns, or to partially knit in these yarns with adhesive properties, in particular on a basic knitted fabric, i.e. plating onto a basic knitted stitch.
  • at least two adhesive yarns are used, which only protrude on one side.
  • Adhesive yarns lead to increased production times and production costs.
  • Another disadvantage of the textile fabric known from the prior art is the lack of a connection between the adhesive sections on one side, in particular the inside, of the fabric with the adhesive sections on the other side, in particular the outside, of the fabric.
  • the opposite adhesive sections are not direct connected to each other, so that the opposing adhesion sections are mutually displaceable when subjected to a load by the wearer, in particular by the generation of shearing forces. A secure hold in the residual limb cannot be guaranteed.
  • a knitted fabric in particular in the form of a stocking, with an anti-slip effect is known.
  • the stocking has an integrated gripper yarn in the sole area.
  • the adhesive yarn is also plated there on a basic knitting thread.
  • Another disadvantage of this embodiment of the knitted fabric known from this prior art is that by plating the adhesive yarn onto a basic knitting thread, the adhesive yarn itself is only attached in the region of the stitch heads formed the fabric surface is exposed. This only achieves an average adhesive effect.
  • a sock which has plush sections knitted into the sole area, in particular in the form of ribs.
  • an additional moisture-transporting yarn is locally knitted into a basic knit.
  • the additional yarn preferably forms plush loops, as a result of which it stands out more strongly on the knitted surface.
  • this improves the moisture transport properties of the knitted fabric.
  • the formation of ribs also "captures" the skin of the sole of the foot between adjacent ribs, so that the frictional connection between the sock and the foot is increased.
  • Another disadvantage of this configuration of the knitted fabric known from this prior art is that only an average anti-slip effect is achieved.
  • the yarn itself which is formed from polyester fibers and transports moisture, does not have any particular adhesive effect.
  • the present invention is therefore based on the object of creating a compressive knitted part which avoids the disadvantages of the prior art, in particular significantly improves the adhesive effect of the knitted part.
  • the hold of the knitted fabric on the wearer should be improved while at the same time increasing the adhesion to an external surface.
  • this consists of at least one stitch-forming basic knitting thread, at least one inserted and/or knitted elastic weft thread, and at least one plush thread that forms plush loops and is plated at least in sections on the basic knitting thread, with the at least one plush thread being an adhesive thread in order to hold the compressive knitted part to give an anti-slip effect, and wherein the
  • Adhesive thread is a silicone, elastane or rubber thread.
  • the adhesive thread particularly preferably has a thread core, preferably made of elastane or polyamide, the thread core being coated or wound with silicone, elastane and/or rubber.
  • the thread is also preferably provided with a fluid-soluble, in particular water-soluble, coating or wrapped with a fluid-soluble, in particular water-soluble, binding thread.
  • a binding thread or coating reduces the friction of the otherwise adhesive silicone material during the knitting process, in particular on the stitch-forming elements (needle, thread guide, etc.) and the thread feed.
  • the knitted part is preferably washed so that the water-soluble binding thread or the coating dissolves and the adhesive properties of the silicone thread or silicone coating come into full effect.
  • a second plush loop-forming plush thread preferably made of polyamide, polyester, polypropylene or natural fibers, is plated at least in sections on the base knit thread of the compressive knitted part.
  • the first plush loops formed by the adhesive thread and the second plush loops formed by the second plush thread are particularly preferably of different heights.
  • the sections with the plush threads forming the plush loops preferably overlap at least partially, so that a multi-layer structure is created.
  • the basic knitting thread knitted to form a stitch forms a first layer or basic knitting level.
  • a second layer or first plush level, in particular for padding, is formed by the plush thread forming the plush loop.
  • a third layer, in particular an adhesive layer, is formed by the adhesive thread forming the plush loop, the loops of the adhesive thread being longer than those of the second plush thread.
  • the plush loops formed by the adhesive thread extend through the basic knitted fabric, so that the adhesive thread protrudes on both sides of the knitted fabric.
  • the stitch heads and stitch feet are preferably exposed on one side of the knitted fabric and the associated stitch legs on the other side of the knitted fabric.

  • the adhesive thread is preferably only partially knitted in in the circumferential direction, forming at least one plush handle within a row of stitches.
  • the adhesive thread can be knitted into the base fabric in sections.
  • the adhesive thread is knitted in in the at least one section, preferably forming plush loops in some areas and only backed or plated in some areas in the basic knit without forming plush loops, in order to form several anti-slip elements arranged next to one another.

  • the present leg garment is characterized by a number of significant advantages.
  • the compressive knitted part By designing the compressive knitted part with a plush thread forming a plush loop that is plated at least in sections on a basic knitted thread, which is a silicone, elastane or rubber thread, the adhesive property of the knitted part is significantly increased.
  • the formation of plush loops, which consist of the loop heads and large parts of the loop loops, with such an adhesive thread means that significantly more non-slip and/or adhesive material is arranged above the base knit surface than is known from the prior art, see above that the knitted part is given a much better anti-slip effect.
  • the adhesive sections are formed on both sides of the knitted part, which are directly connected to one another, i.e. are formed in one piece and extend through the knitted part, so that when the wearer applies a load, the opposing adhesive sections directly transmit the applied shearing forces without the opposing adhesive sections being displaced relative to one another, whereby slipping of the wearer relative to the knitted part can be completely avoided, which is also a significant advantage.
  • a further advantage of the invention is the cost-effective production of one or more anti-slip sections, in particular on two opposite surfaces of a knitted part.
  • the design of the one or more adhesive sections according to the invention in particular the way in which the adhesive thread is integrated into the basic knitted fabric, makes it possible for the majority of the adhesive thread, namely the stitch heads and stitch feet formed by the thread, as well as large parts the loop leg, on the inside of the knitted fabric or on the outside of the knitted fabric is arranged so that it is freely accessible.
