Definitions

  • the invention relates to a method for realistic Simulation of a warp and weft thread real fabric with a pattern.
  • the invention is based on the object to demonstrate the method of the type mentioned, in which the tissue including its pattern can be visualized without that weaving of the fabric becomes necessary. In doing so preferably different types of fabric, also in one individual tissues can be summarized, representable be.
  • the invention proposes a method for solving the problem according to claim 1.
  • the pattern for the tissue to be displayed be shown on a graphic template or be entered into a data processing system can.
  • the other embodiment assumes that already A disk exists that contains information about a tissue contains.
  • the patterns are marked with a Data processing system recorded and, if necessary, for example on a screen.
  • the sample can be scanned from a template or directly on a Screen. After that, the tissue warp and weft threads forming a crossing scheme assigned, whereby the bonds are determined from those the tissue should exist.
  • the second embodiment assumes that the pattern already - for example on a punch card saved - available. There can already be data about the crossing pattern of the warp and weft threads must be present. Depending on the information already available the missing information in this embodiment added. The pattern and possibly the Crossing scheme on any storage medium be saved.
  • the pattern and the crossing scheme are in one Data processing system recorded. Then under Consideration of the thread-specific parameters and the Fabric parameters of the course of the warp and weft threads certainly. In particular, the control functions for a weaving machine. To this extent there is a characteristic difference to teaching according to textile practice International, Vol. 43, No. 1, 1988, pp. 39-44, which is considered to be the closest prior art. That there Described design process for shaft-patterned fabrics is limited to the visual representation of a fabric. It leaves essential tissue parameters, especially those that come from real weaving technology in a weaving machine, disregarded, e.g. the harness division, control the shot density or the like.
  • EP 0 302 576 B1 describes a method for simulating of a dyed fabric.
  • the colors of the Tissue with colors measured spectrophotometrically compared and corrected so that the simulated and the actual colors match.
  • this known methods only the colors are considered.
  • the look of a actually woven fabric becomes strong just because of this Factors determined.
  • the simulated tissue is said to be the tissue reproduce as accurately as possible. Because of neglect this one, which decisively determines the appearance of a fabric Factors, the simulated tissue shows deviations from one actual tissue so that an assessment of whether that simulated fabric to be woven or not, difficult is.
  • Figure 1 shows a so-called Plain weave, each with a warp and Cross the weft thread, the warp threads vertical and the Weft threads run horizontally.
  • the plain weave is additionally in a dual representation, in this case in the form of a so-called binding cartridge.
  • the space represents between two vertical lines K a warp thread and between two horizontal lines S a weft thread.
  • To mark the crossing points, that is, the crossing of the warp and weft threads is on all places where the warp threads over the weft threads lie (chain runs), the square in question black marking has been highlighted here.
  • Corresponding the white squares on top indicate weft threads (Draft of the chain).
  • FIG 2 is a so-called Panama weave, consisting of two intersecting warp and Weft threads are formed, along with the associated one Binding cartridge shown analog.
  • the process according to the invention determines the crossing scheme, for example in the dual representation in the form of the binding cartridge, the mesh.
  • the Crossing points of the warp and weft threads through their respective spatial coordinates can be determined. For example when using a Cartesian coordinate system (x, y, z) where the orientation of the z-axis is the depth describes a crossing point of a warp and Weft by an x and y value and by two z values, az value of the warp thread and az value of the Weft, determined.
  • the diameter can also be added the threads are taken into account, the influence on the respective z coordinates.
  • the thread-specific parameters can be the number of Color components of a single thread and their distribution, the formation of the thread surface and / or the material of the thread.
  • the number and distribution of colors that make up a putting together a single thread influences the appearance of one Fabric.
  • the thread surface also has a decisive one Influence on the look, for example, a fluffy one Thread in a fabric works differently than a thread with one smooth surface.
  • a Fancy yarns are taken into account.
  • the material of a thread strongly determines the behavior of one Thread in a fabric.
  • a thread that is loosely spun covers a lot more under this thread arranged more thread than a thread that is very tight is spun.
  • the course of the warp and weft threads is also determined by the Tissue parameters determined.
  • the material feed at Weaving means the speed at which the goods is subtracted, the strength of the fabric and thus the mutual, changing the appearance of the tissue, Influence the threading together. The faster the Material feed runs, the looser it is Cohesion of threads and the lower the Change in shape of individual yarn sections.
  • Warp threads are taken into account when weaving. Let also specify the control functions for a weaving machine.
  • the appearance of a fabric can also be determined by the Floating behavior of the threads, the prevention of individual Threads, the thread course at the crossing points and through different types of bindings can be influenced.
  • Floating behavior means that a Weft over several adjacent warps on the Top is guided.
  • a weft that is not like in the plain weave (Figure 1) alternately above and below neighboring warp threads, but over several neighboring warp threads are widened much stronger on the surface. In contrast to when the weft is tied runs over several Warp threads on the underside.
  • the warp and weft course corrected in this way can optically on an output unit, for example a Screen, or through an output device, for example a printer to be made visible.
  • the individual warp and weft threads of the fabric can also Colors can be assigned. It is advantageous if the Colors assigned to the threads after the gradient has been corrected because the colors then correspond to the aforementioned Correction factors on the actual visual impression in real tissue can be adjusted without that Tissue must be determined again, so that time and therefore Costs can be saved. By using colors it is also checked whether the tissue is displayed correctly.
  • the colors of the depicted Fabric matches the colors of the actual fabric can be achieved if the colors in Dependence on those that can be represented with the output unit Colors can be chosen. It is ensured that the Color representation also with the entered color values matches.
  • the color values specified, for example, in RGB coordinates can come from a color atlas in which the Coordinates are given.
