Definitions

  • the invention relates to a knitted fabric according to the preamble of claim 1 and to compression articles produced from such a knitted fabric.
  • elastic knitted fabrics are usually used which have a certain elasticity. Due to this elasticity of the elastic knitted fabric, the compression article applied to limbs, for example an arm or a leg, exerts a compression pressure on the extremity.
  • the compression effect exerted on the extremity is inversely proportional to the elasticity of the elastic knitted fabric, i.e. an elastic knitted fabric with low elasticity exerts a higher compression pressure than an elastic knitted fabric with high elasticity.
  • the extensibility is to be understood here as the amount of a force that is required to stretch the knitted fabric by a certain amount.
  • the invention has for its object to provide a knitted fabric for producing a compression article, which areas with different heights Compression has, the difference in the extensibility of the individual areas should be as high as possible and in the simplest possible and inexpensive to manufacture.

  • Figure 1 shows the stitch pattern of a circular knitted fabric according to the invention.
  • the knitted fabric has a first area 1 with a certain elasticity.
  • the area 1 is seamlessly followed by a second area 2 with greater elasticity.
  • the two areas 1 and 2 are knitted together.
  • Both areas 1, 2 have a basic knitted fabric which is formed by a knitting thread 3 and, in the exemplary embodiment according to FIG. 1, is formed as a right-left knitted fabric with stitches 7 arranged in rows m.
  • Both areas 1 and 4 are crossed by weft threads 4.
  • a weft thread 4 is drawn in every second row of stitches.
  • these are the stitch rows with the numbering m-4, m-2, m and m + 2.
  • Each weft thread 4 is in this case non-stitch-forming integrated into the basic knitted fabric formed by the knitting thread 3.
  • Both the knitting thread 3 and the weft threads 4 are formed from an elastic thread, for example a core thread wound with polyamide, the weft thread 4 being stronger than the knitting thread 3.
  • every second stitch is omitted by the knitting thread 3 on the corresponding place is not formed into a stitch but is laid flat.
  • the stitch under the missing part of the row of stitches underneath (this is row m-1 in FIG.
  • each area has different extensibility to one another.
  • the extensibility of each area is essentially determined by the extensibility of the inserted weft thread 4.
  • the weft thread has a comparatively short free length, i.e. the weft thread 4 is bound between the stitches over a substantial region of its length.
  • the free length of the weft thread 4 in the first region 1 is significantly greater, i.e. the weft thread 4 has much greater lengths there, which are not bound in a stitch.
  • the weft thread 4 in the first area 1 is drawn up from a stitch into a stitch of the stitch row above it, that is to say into an elongated stitch 8.

  • the basic thread 3a consists of a thin elastic thread, for example an elastane thread, which is wrapped with polyamide.
  • the plating thread 3b is formed by a polyamide thread.
  • every second stitch m in every stitch row m is shorter than the stitches 7 of the basic knitted fabric.
  • These shorter stitches k are knitted with a second knitting thread 5, as shown in FIG.
  • the second knitting thread 5 produces the entanglement of the short stitches k of the course m with the stitches k above or below it of the course m + 1 or m-1 above or below. In this way, the mesh density in the first area 1 is higher than in the second area 2.
  • Both areas 1 and 2 are in turn traversed by weft threads 4 that do not form a stitch.
  • the weft threads 4 are bound between the right r and left 1 stitches of the basic knitted fabric.
  • the weft threads 4 are also incorporated into the basic knitted fabric to different degrees in the two areas 1 and 2 in the flat knitted fabric of FIG.
  • a higher mesh density is present in the first area 1, which leads to a stronger integration of the weft threads 4.
  • the extensibility of the first region 1 is less than that of the second region 2 with a lower mesh density.
  • the boundary line G between the first region 1 and the second region 2 also runs approximately perpendicular to the weft threads 4.
  • the knitted fabric according to the invention is distinguished in that the difference in the elasticity of the respective zones is made substantially larger can be. Compared to the known knitted fabrics, in which the difference in extensibility is achieved by using different types of yarn in the individual zones, the knitted fabric according to the invention is much easier and also cheaper to produce.

  • the second area 2 with greater elasticity and consequently less compression effect is arranged in the compression stocking in the area of the calf. This is intended to ensure that the stocking in the calf area exerts less compression on the leg than in the rest of the area, thereby protecting the calf muscles when walking.

  • the lower calf area 12 has an average extensibility (and thus an average compression pressure). Compared to the lower shaft area 12, the calf area 10 has a higher extensibility (and thus a lower compression effect) and the shin area 11 has a lower extensibility (and thus a higher compression effect) compared to the lower shaft area 12.
  • the lower shaft area 12 preferably has a compression pressure between 18-21 mm Hg and the compression pressure in the calf area 10 is at least 10% lower than in the area 12 of the shaft 8 underneath.
  • the compression pressure in the area 11 of the shin is, in contrast, by more than 10 % higher than in the area 12 of the shaft 8 underneath.

As a result, particularly good stabilization of the foot and good blood circulation are promoted in area 11 of the shinbone.
  • the lower compression pressure in the calf area 10 relieves the calf muscles and therefore does not tend to fatigue as quickly, which is particularly advantageous when wearing this sock during sporting activities.
  • the compression pressure in the calf region 10 decreases continuously or in stages from bottom to top.
  • the calf region 10 has a first, lower region 10a with a lower compression pressure than the shaft region 12 underneath and a further region 10b adjoining it upwards and in the rear region, which is opposite the first Region 10a has a further reduced compression pressure.
  • the compression pressure in the lower calf area 10a is approximately 55% of the pressure of the underlying shaft area 12 and the compression pressure of the uppermost calf area 10c located at the rear is only 50% of this compression pressure.
  • the shaft 8 is closed by an elastic collar 18.
  • the collar 18 is formed from a soft knitted fabric, which lies against the calf of the user as wrinkle-free as possible.
  • the transition region 13 between the foot part 9 and the shaft 8 likewise has a lower compression pressure than the adjoining regions of the foot part 9 and the shaft 8, that is to say in particular the lower shaft region 12 or the heel 15 and the tension zone 14 less compression effect in the transition area 13 ensures better mobility.

Abstract

L'invention concerne un tricot comprenant une première zone (1) qui présente une faible extensibilité, et une deuxième zone (2) qui est reliée sans couture avec ladite première zone et qui présente une extensibilité plus élevée. L'objectif de cette invention est de créer un tricot pour produire un article de compression comportant des zones de compression de niveau différent, de manière que la différence de compression des zones individuelles soit aussi élevée que possible et puisse être obtenue de la manière la plus simple et la moins onéreuse possible. A cet effet, le tricot est constitué d'au moins un fil de tricot (3) qui forme d'un tricot de base, et de fils de trame (4) qui s'intègrent dans le tricot de base. La différence d'extensibilité des deux zones (1 ; 2) est créée par une intégration différente des fils de trame (4) dans le tricot de base. Cette invention concerne en outre un article de compression, en particulier un bas de compression, qui est produit à partir d'un tricot selon l'invention.
