Definitions

  • the present invention relates to a method for manufacturing a three-dimensional knitted fabric, i.e. of a knitted fabric, whose surface is spatially shaped, e.g. with helmets or the heel of socks is the case.
  • the shape is in realized in a known manner that stitches in certain Areas of the knitted fabric are increased and / or reduced.
  • the aim of the present invention is thus a three-dimensional one Knitted fabric to create that relative to its entire area is insensitive to mechanical influences.
  • this object is achieved by a method Claim 1 solved.
  • Advantageous developments of the invention are the subject of the corresponding subclaims.
  • the task is further solved by a textile material according to claim 10.
  • the invention particularly relates to manufacture technical textiles.
  • the meshes increase or decrease no longer in one or more defined linear areas, but in many Locations in the deformation area preferably as possible are evenly distributed. This way the deformation integrated more homogeneously into the knitted fabric, i.e. it doesn't arise more excessively stressed edges in the marginal area of a narrowly defined one Deformation area resulting in a premature break tend.
  • the technology according to the invention enables all possible shapes such as. Balls or bowls can be produced without e.g. at there is a line in conventional speckle technology, within which all stitches are removed so that the knitted fabric subject to special loads in the area of this line is. Because on the one hand the invention increases or reduction or inactivation of needles over the entire area to be distributed, causing the deformation of the knitted fabric no longer occurs along a line, but homogeneously in the entire knitted fabric. The deformation is still on every single point of increase or decrease or inactivation / activation of needles not as big anymore because of the increase / decrease / inactivation of the large number of positions every single digit can be smaller. It means that the deformation of the knitted fabric at a point of increase / decrease / inactivation is lower than the previous status of Technology, where in one or a few places the whole for the Shaping necessary increase / decrease / inactivation took place.
  • the degree of deformation is preferably determined by density, i.e. controlled the mutual distance of the places where the Increase / decrease / inactivation takes place. It's a strong one Deformation desired, so these places are in a higher Density arranged than in areas where there is less Deformation is desired. In this way, homogeneous pieces of textile can be produced in the desired manner less have deformed areas and more deformed areas. In this way, homogeneous knitted fabrics can be made in all the desired ones Make shapes.
  • Another way of making three-dimensional knitted fabrics is that needles in certain areas of the Knitted fabrics are inactivated while using the needles in the other areas. Through later activation these inactivated needles e.g. after one or more Rows of stitches are achieved in this inactivated area Contracting the knitted fabric, what again in the desired manner can be used to achieve certain shapes. If e.g. with a knitted fabric in the edge areas of the flat knitting machine Needles inactivated and this inactivation at a distance some rows of stitches repeated in different widths, so you get a spherical structure with a very homogeneous Structure. Again, the needles should only be inactivated over a few courses, so that too strong Deformation of the knitted fabric can be avoided at one point.
  • the width (number of needles) of inactivation be changed alternately, so that this also results in a Scattering of the deformed areas in the deformation area can be achieved.
  • These points are at the points an inactivated area to a knitted area Adjacent area.
  • a distributed increase / decrease in stitches within the Knitted fabrics can be used in a particularly advantageous manner Achieve use of twin needles.
  • twin needles For example, with the A and B needles of the twin needle are knitted alternately, which gives you a stitch count that is twice the number corresponds to the active twin needles or conventional needles. If you want to reduce the number of stitches, you knit just continue with one of the A or B needles of the twin needle. This results in a reduction in the number of stitches to Half with the same width of the active area of the Needle bed. This reduction can also be done in other stages be achieved if you reduce to one of the two Needles of the twinned needle not with every twinned needle but e.g. just every second. There is also an increase in Achieve a number of stitches if you start with knitting one of the two needles of the twin needle to knit with passes over two needles, the two needles being the twin needle be operated successively.
  • Fig. 1 shows a knitting scheme for producing an approximately spherical Knitted fabric.
  • the figure actually shows that knitted textile surface 10.
  • the shape of the textile is now achieved in that within a mutual area b the textile surface 10 needles partially or completely inactivated be so that in this area over one or more Rows of needles are not knitted.
  • the needles are then activated with the last ones knitted stitches. This means that while the time of the lack of activation of the needles in the peripheral area b of the knitted fabric 10 certain areas of the course just drop out.
  • the courses before and after the dropped Area are simply knitted together, which the knitted fabric in this area according to the number of not knitted courses are pulled together.
  • the Points at which deformation occurs are the Points 11.
  • the inactivated areas border to the knitted areas. Therefore, it is preferred the width of the inactivated area, i.e. the number of the inactivated needles varies constantly, so that the deformation points 11 evenly within the deformation range b are distributed. In this way you avoid further a defined structuring of the acceptance, which in turn with weakening the knitted fabric.
  • the mutual The distance between the inactivations 12, 14, 16 is relatively constant, so that the deformation points 11 also in the direction of meshing have an approximately uniform distance.
  • the needles are in a first short area 12 inactivated, which for example only goes over 20 needles.
  • the stitches are inactivated in an area 14 which is extends over the entire width b of the shaped region.
  • the In this case, inactivation would e.g. Affect 60 needles.
  • the needles are over activated a width 16 between the two above Widths, e.g. with 40 needles. So the deformation points 11 evenly distributed over the width of deformation b.
  • the inactivated areas 12, 14, 16 are again and again interrupted by knitted areas 18, in which What is knitted over the entire width of the knitted fabric Direction of meshing at approximately uniform intervals Points 21 leads.
  • Knitted fabric 10 In the middle of the knitted fabric 10 runs Area 20 where knitting is carried out while continuing outward an area 22 extends in which the knitted fabric in one Distance of several rows of stitches that have not already been knitted having. Take these non-knitted areas towards the outside, as can easily be seen from the drawing leaves. If you keep in mind that the knitted sections 18 joined together at their upper and lower edges are, it is easy to understand that that shown in Fig. 1 Knitted fabric 10 have an approximately spherical shape likely.
  • the inactivation 12, 14, 16 runs in the knitted fabric in each case over two successive courses. Of course it is possible to have different inactivated areas 12, 14, 16 without interleaved areas 18 hang directly together if you have a stronger deformation wants to achieve.
  • the degree of deformation is determined by the distance, i.e. the sequence of inactivations and the breadth of Deactivation areas 12, 14, 16 are set. The wider the inactivation areas and the sequence of inactivations are the greater the deformation.
  • FIG. 1 shows a process for producing three-dimensional Describes knitting structures by inactivating needles
  • 2 and 3 show a knitting method in which a three-dimensional Form by increasing or decreasing stitches will be produced.
  • 2 shows a method in which the three-dimensional shape of the knitted fabric in one defined area 30 takes place.
  • first stage 32 doubles one stitch, i.e. a stitch in split two stitches so that instead of one There are now two wales.
  • the two are split again Wales in two wales so that now there are four wales, which are still at 36 once split into eight wales.
  • the area 30 is the widest.
  • two stitches are pulled together in one stitch, i.e.
  • the knitted fabric is under an elevated mechanical load due to the deformation in this Border area. This deformation is associated with an earlier one Wear or fatigue of the material or with an increased Susceptibility to mechanical stress.
  • the increase takes place according to the invention not in an area 30 as in FIG. 2, but on five different places 50, 52, 54, 56, 58, at each one stitch divided into two stitches (split) and then can be combined again into a stitch.
  • the duration of the division is different for the five positions, so that a homogeneous distribution of the increase / decrease points is within the knitted fabric.
  • the Areas 50, 52, 54, 56, 58 of the increase / decrease knitted through Wales 60 arranged to increase homogeneity serve the knitted fabric in the entire molded area.
  • the shape of the knitted fabric is much more homogeneous than that of the State of the art and that such a knitted fabric is much more resistant against mechanical stress and premature Is material fatigue.
  • the geometry of the three-dimensional molded area can also be better by the invention are controlled and that by the distance between the positions 50, 52, 54, 56, 58 and over the length of the increase or decrease on each single digit 50, 52, 54, 56, 58. In the present example is in the middle range, i.e. the area of greatest bulge the longest increase in existence. In the adjacent ones Digits 52, 56 the increase is less long and in the am Outlying areas 50, 58 the increase is only relatively short, e.g. the increase / splitting extends over one to ten rows of stitches.
  • the present invention is therefore suitable for generating all possible geometric shapes such as spheres, cones and all types bulges of regular or irregular nature.
  • Both the increase / decrease in the stitches and the partial Inactivation of the needles in a row of stitches can be done in one uneven spacing and to a different extent respectively. It can continue to be controlled or statistical, in order to achieve the highest possible homogeneity. In the Distribution of these sites and the distribution of the size of the increase / decrease / inactivation however, care must be taken that overall an approximately uniform shape of the knitted fabric the entire area is achieved.
