Definitions

  • the invention relates to a knitted fabric comprising a basic knitted fabric knitted from at least one basic knitted yarn, and at least two plush yarns forming the first and second plush loops which are laminated onto the basic knitted yarn.
  • a fabric is for example off EP 1 997 394 A1 known.
  • a pronation support and at least one damping zone are provided on the knit side, which may comprise a plush knit.
  • This plush knit can be formed from a plush thread which has a lower yarn count, that is thicker than a second plush thread, from which a plush knit of a plush section adjoining the region of the pronation support or the damping zone is formed.
  • the support effect of the pronation support and the damping effect of the damping zone can be adjusted or improved, in particular compared to the plush section knitted from a thinner plush thread.
  • the local properties of the knit part is influenced by the formation of plush loops of different thick plush threads.
  • the various sections in which the various plush loops are present are separated from each other in the known knit part.
  • the invention is based on the problem of providing a contrast improved knitted part.
  • first and second plush loops are of different heights.
  • the two plush-leg forms differing in their height. That is, the plush loops of the first shape are higher or longer than the plush loops of the second shape, and thus the first plush loops project somewhat further out of the plane of the base knit than the second plush loops.
  • the structure of the knitted fabric according to the invention results in a quasi-multilayer or multi-level structure.
  • the first layer or plane forms the basic knit, which is designed, for example, as a right-left knitted fabric.
  • the second layer or plane forms the shorter plush loops protruding slightly from the basic knit plane, while the third layer or plane forms the longer plush loops which protrude further from the basic knit plane and also protrude beyond the first plush pile plane.
  • one or more zones are formed in which the first and second plush loops are present together, so that the quasi-zone results in the three-level or three-layer structure.
  • a corresponding knit part properties which are perceived by the wearer to be comfortable or advantageous, can be set, for example with regard to damping, thermal effect, etc
  • a second characteristic of the knitted part can be influenced or adjusted via the second lower layer of the shorter plush threads, for example the moisture removal from the knitted part due to the capillary action and the fact that the plush loops are tied to the right side of the warning.
  • the third level is the basic knit. It can therefore be improved by the training of this three-shift or three-level structure with the two different Plush strap layers or levels, for example, an optimized climate management in conjunction with a pleasant feel and a pleasant wearing comfort can be achieved.
  • the plush loops are formed from two threads by means of a board that has a single dimension. That is, the distance between the base knitting yarn and the first and second plush loops is the same immediately after knitting.
  • a post-treatment in particular a thermal treatment, which shrinks a thread, so that shorten the plush knitted from it, while the other thread and thus the plush knitted from it almost keep their length. If knitting with different blanks is possible, the different plush loops can be formed directly during knitting without aftertreatment.
  • plush threads may show a slightly different shrinkage behavior compared to the first and second plush threads, so that adjust the different handle lengths in the context of post-treatment.
  • the two plush threads are made of different materials and / or have different properties. It is therefore preferred to use different plush threads, which either consist of different materials, such as polyamide in one case and a natural fiber such as wool in the other case, but which, alternatively or additionally, may have different properties, among them For example, a different shrinkage behavior under thermal treatment and / or a different elasticity and / or a different surface and / or a different thickness by way of example, but not to mention conclusive.
  • a plush thread made of a synthetic fiber shows a low tendency to absorb moisture, and is therefore particularly suitable with regard to a moisture transport through the knitted part from the inside to the outside due to the capillary action.
  • a natural thread for example made of wool, from which the longer or higher plush loops are formed, which rest directly on the skin, by heat-retaining and temperature-compensating properties, it is breathable and dirt and water repellent, and its antibacterial properties can be used become and the like.
  • threads of different thicknesses can be used so that the padding properties of the plush zone can be further varied.
  • the plush thread can be textured and highly elastic and be executed with or without a soul. This means that there is also a high degree of flexibility and variability in this respect.
  • the two plush threads in separate courses of the basic knit bring.
  • either only first or only second plush loops are introduced in each course of the basic knit.
  • course is based on a two-dimensional development of the circular knit, that is, the circular knit quasi cut open and considered planar with a beginning and an end of each course becomes.
  • the first plush thread or the first plush loop is knitted in a first course
  • the second course is not covered with a plush thread
  • the third course is provided with the second plush thread and thus with the second plush loops
  • the fourth course is again not with a Plush thread provided
  • the fifth course is provided with the first plush thread, etc.
  • the plush threads seen in the circumferential direction, are introduced into the basic knit.
  • the plush yarn course and thus the plush looper arrangement is considered perpendicular to the knit longitudinal direction, namely in the circumferential direction of the respective course row.
  • the plush threads each run in a spiral through the basic knit. Based on the processing described above so the plush thread runs from one end of the developed knit part to the other end. Accordingly, in the real knitted fabric, an annular plush zone running around the entire knit part circumference is formed.
  • the plush threads in the respective course series extend only in sections in the circumferential direction.
  • the plush threads respectively the area in which the plush loops are formed, starting from the two-dimensional development described above, thus extend only slightly between the left and right edges of the unwound knitted part, and therefore only over a limited number of wales.
  • both sides of the basic knitted limited zone with plush loops are formed.
  • a plush or upholstery section on the knitted part in which the first and the second plush thread in each of the same row of stitches, each sectionally extending in the circumferential direction, is introduced into the basic knit. While in the embodiment described above, the individual courses are provided only with one or the other plush yarn, in this embodiment, both plush threads are entangled in each case a common course, that is, in the course of the first and second plush loops are provided.
  • first and second plush loops are at least partially in common wales. That is, both first and second plush loops are present in a wale, for example, alternately or spaced apart across respective empty stitches in wale direction, or in the form of individual wale sections, each wale section comprising two or more first or two or more plush loops, etc. Alternatively It is also conceivable that the first and second plush loops are offset from each other and in different wales.
  • the plush loops are not knitted on each needle, but at least one empty stitch in which the respective plush thread is afloat or catch is provided, so that from stitch row to stitch row respectively wales to wales a corresponding Training offset.
  • the number of first plush loops and the number of second plush loops may be substantially the same, alternatively, the number of first and second plush loops may also be different. That is, it is possible to knit the plush tiers or plush tufts either at the same density, or to knit different densities, so that there are any variations depending on the desired property of the fabric in terms of moisture removal and thermal properties.
  • a density variation can of course also be achieved by using different thickness plush threads.
  • An expedient, but by no means limiting embodiment provides that one plush thread in the form of a 2: 1 plush and the other plush thread in the form of a 1: 2 plush is knitted.
  • the lower, shorter plush loops can be knit as a 2: 1 plush, that is, two plush stitches and one empty stitch in which the plush thread is inserted only in the base knit are deposited.
  • the second knitted thread, from which the higher or longer plush loops are formed, can be knitted as a 1: 2 plush.
  • the first and the second plush loops can protrude to the same side of the basic knit. So they both extend to the left side of the goods, so to the carrier in the support position facing side.
  • the first plush legs protrude to one side of the base knit and the second plush loops to the other side of the basic knit.
  • weft thread is inserted into the basic knit.
  • This weft thread runs as a catch and float through the basic knitted mesh. It consists of a sufficiently elastic material, such as elastane and can be used with or without wrap.
  • the weft thread is inserted at least in the courses in which the plush thread forming the lower plush loops is inserted.
  • the weft yarn in each second course, in which the shorter plush loops forming plush yarn is inserted inserted and runs as a catch and float through the individual basic knitted mesh rows. This causes the weft thread, when inserted as a catch through the stitches on which the shorter plush loops are plated, to pull the plush thread inwardly into the base knit.
  • the weft thread is thus inserted as a catch in the plush loops and pushes the shorter plush loops in the basic knit. This is advantageous for the same if the thread forming the shorter plush loops and thus the knitted plush loops serve for moisture transport.
  • the knitted part itself can be designed, for example, as a stocking, wherein the plush loops form an at least local padding. It is obvious that the plush loops can be knitted at any point on the stocking, for example in the area of the sole of the foot where, for example, the center of gravity is placed next to the padding, in particular on the moisture transport. In contrast, for example, in the area of the heel in the transition to the Achilles tendon the focus is more on the padding than on the moisture transport. All of these different properties can easily be varied and adjusted by the variation provided according to the invention with regard to the plush threads used, as well as the plush leg lengths and the plush pith densities, etc.
  • the invention further relates to a method for producing such a knitted part.
  • This method is characterized in that knit with at least one basic knitting a basic knit, are knitted into the at least two plush threads to form first and second plush loops, wherein either the first and the second plush loops are knitted with different heights, or wherein the first and second plush loops are knitted with the same height and the fabric is subsequently aftertreated, so that the one plush thread shrinks while shortening the plush loops knitted from it.
  • the corresponding first and second plush threads are knitted to form the first and second plush loops during the production of the knitting of the basic knit.
  • the first and second plush loops are already knitted in-house during the knitting process with different lengths or heights.
  • the finished knitted part thus already shows the multilayer or multi-level construction.
  • the various plush heald lengths are then produced as part of a post-treatment by shrinking a plush thread through this post-treatment, while the other plush thread almost retains its shape.
  • a first and a second plush thread are used, which change in their shrinkage behavior under the influence of appropriate environmental conditions.
  • one plush thread and thus the plush loin formed from it shorten while the other plush thread and thus the plush loops formed from it retain their original length.
  • the aftertreatment of the knitted fabric can, for example, be a thermal treatment, in particular by means of hot or hot water or steam, that is to say that the knitted fabric part is washed or steamed, for example, the treatment temperature being equal to or above the temperature at which a plush yarn shrinks becomes.
  • a thermal treatment in particular by means of hot or hot water or steam, that is to say that the knitted fabric part is washed or steamed, for example, the treatment temperature being equal to or above the temperature at which a plush yarn shrinks becomes.
  • irradiation in particular with UV light.
  • UV light can also be achieved a kind of thermal treatment, since the different threads absorb the UV light in different ways.
  • only the irradiation, for example with UV light influences or alters the material properties of a plush thread so that it shrinks or shortens.
  • Fig. 1 1 shows a knit part 1 according to the invention in the form of a stocking 2 with a foot section 3 and a calf section 4.
  • the sock 2 consists of a basic knit 5, which is shown here on the less dense dotted line.
  • a plush or padding zone 6 is formed, by additionally knitting into the basic knit 5 two different plush threads which form plush loops of different lengths.
  • the plush or upholstery region 6 is here shown as ring-shaped or cylindrical around the stocking body. Of course, it is possible to form this plush or padding area 6 only locally.
  • this plush or upholstery area 6 after the plush loops knitted from the two different plush threads are of different lengths, there is consequently a three-layer or three-level construction, namely the one Layer of base fabric 5, then the plane formed over the shorter plush loops, and finally the plane formed over the long plush loops.
  • the properties the plush or padding area can be adjusted or varied in a wide range.
  • the plush or padding region 5 is designed so that it on the one hand provides a tactile pleasant padding and on the other hand allows a good moisture removal respectively a good moisture transport through the knitted part to the outside.
  • This is achieved by knitting the longer plush loops, which are furthest from the plane of the basic knit, and which rest against the skin of the wearer, for example, from a natural thread such as wool or silk.
  • the plush loops, which are shorter and which primarily serve to transport moisture, are knitted, for example, from a synthetic fiber such as PA and are preferably an intermediate layer between the basic knit layer or plane and the layer or plane of the longer plush loops. If additionally a weft thread is used which lies as a catch in the shorter plush loops, they are additionally pressed into the basic knit, which is advantageous for the moisture transport through the basic knit outwards.
  • FIG Fig. 2 An example of a stitch pattern for forming such a plush or padding area 6 is shown in FIG Fig. 2 shown. Shown are a plurality of courses I - VI, which follow each other in the longitudinal direction L, wherein each course of stitches I - VI consists of a plurality of individual, in the circumferential direction U adjacent mesh. In the circumferential direction, seven needles (exemplarily denoted by the numbers 4 to 10) of the circular knitting machine, that is to say therefore seen in the longitudinal direction of the knit, are represented by seven wales.
