Definitions

  • the invention relates to patterned fabric, in particular jacquard fabric according to the preamble of claim 1 and a method for its production according to the preamble of claim 11.
  • WO 00/60151 describes a patterned fabric and a method for its production in fabric technology with warp threads that form a shed and with weft threads.
  • this method at least four weft threads of different basic colors, which form a thread group, are inserted in a specific, constant order, such that a constant cell is formed together with a warp thread.
  • the weft threads are tied off by regular ties with repeat repetition so that a color cell with a certain color impression is created.
  • a weaving program is created to produce a jacquard fabric with a representation. For this purpose, the representation on a template is broken down into weavable pixels or color cells. Due to the low resolution of the human eye, the mixed colors are generated in the tissue.
  • DE 44 38 535 discloses a method for jacquard weaving a colored fabric.
  • a representation to be woven is broken down based on the locking method known from printing technology.
  • an original is transferred to a computer by scanning and displayed on the screen with a very high number of colors.
  • the colors are then reduced to a representable or desired number of colors.
  • this number of colors is broken down into halftone dots, ie into pixels with the colors red, yellow and blue as well as black and white, the halftone dot being the size of a weavable dot.
  • the weaving program is created using computer technology, with each grid point corresponding to a weaving point. These weaving points are tied using the classic jacquard process, ie regular ties with repeat repetitions are used.
  • the known method has significant disadvantages.
  • An experienced specialist with binding experience is absolutely necessary to carry out the process. It has been found that in the case of woven colored representations in the colors yellow, red and blue, the color mixture is poor, i.e. they do not have all the colors of the original. As a rule, corrections are necessary to improve the woven appearance. Such corrections can, however, only be carried out by an experienced specialist with binding experience.
  • color separation for reprography it can be assumed that a color mixture occurs in the area between the printing inks during the printing process. In other words, the printed color dots are not clearly limited, but the printing colors of the neighboring color dots partially flow into one another in the edge area.
  • the representation is broken down into grid points, which form a web point with a clear boundary. The mixing effects are to be created by the low resolution of the human eye.
  • the object of the invention is to improve the patterned fabric mentioned at the outset, in particular jacquard fabric and the process mentioned at the outset for its production. According to the invention, this is achieved by:
  • the fabric according to the invention consists of warp threads and weft threads which form a thread group and are bound with a warp thread in a cell in such a way that the cell has a certain color impression.
  • the cell is formed by ties which are irregular in the warp direction and weft direction without repeating repeat of at least two warp threads and two weft threads.
  • the irregular weave advantageously results in an improved re-production of the representation to be woven in the tissue.
  • At least one weft thread of the thread group can cross at least one warp thread above on the face side of the fabric, so that a point is represented with a color.
  • further weft threads of the thread group can be arranged above the warp thread.
  • the weft threads can also float.
  • the fabric advantageously has weft threads with different base colors.
  • the thread group can consist of weft threads in the colors black and white.
  • the thread group advantageously comprises weft threads in the basic colors red, green, blue, yellow, black and white or magenta, cyan, yellow, black and white.
  • weft threads For larger, single-color areas, it is advantageous if regular binding is provided. It is advantageous if the weft threads float over a maximum of forty-eight warp threads on the face side of the fabric, because this gives the face side of the fabric a better impression. The fact that the weft threads float over a minimum of four warp threads on the back of the fabric advantageously improves the overall impression of the fabric.
  • a file format is created from a template of the representation to be woven and the representation to be woven in pixels from at least four selected basic colors disassembled.
  • each base color is broken down into pixels with a color depth of 8 bits.
  • the pixels of the base colors are each saved on a separate bitmap and then the color depth for each base color is reduced to 2-bit.
  • the bitmaps of the basic colors are then shifted by one pixel each and then combined to form a further bitmap with the basic colors.
  • a weaving program for a jacquard weaving machine is created, which provides for the use of irregular weaves without repeat repetition of weaves and according to which the fabric is produced on the jacquard weaving machine
  • a file format is created from a specified file format, which has a high resolution and represents a reproduction of the representation in the tissue true to the original.
  • the file format is transferred to a web program and converted into a webable data format.
  • the fabric density can advantageously be improved.
  • the bindings are determined on the basis of the data in the further bitmap and a predetermined warp / weft ratio is included when the web program is created.
  • the execution of the entry device can be simplified in an advantageous manner.
  • the sequence of the base color of the weft threads can advantageously be freely selected when entering, so that the representation to be woven can be adapted to the color impression of the template.
  • a weft thread of the thread group can be tied in such a way that the weft thread crosses over a warp thread on the face of the fabric. A color point is thereby advantageously formed. Two or more weft threads can also be tied in such a way that an effect of color mixing is achieved.
  • FIG. 1 is a block diagram of an execution of a manufacturing process for a
  • Fig. 3 shows an enlarged detail A of the template of Figure 2 on a larger scale after the color decomposition of the representation in selected
  • Fig. 9 is a block diagram of a further embodiment of the inventive
  • FIG. 12 is a top view of the fabric of FIG. 11.
  • FIGS. 1 to 4. 1 shows, in the form of a block diagram, the steps required for producing a jacquard fabric with an illustration.
  • 2 shows a template with the representation to be woven, which is converted into pixels by color decomposition and represents the basis for a weaving program (FIGS. 2 and 3).
  • An embodiment of a fabric according to the invention is then produced with a jacquard weaving machine and is described below.
  • FIG. 5 shows a binding cartridge for the fabric to be produced, according to which weft threads in the basic colors red R, green G, blue B, yellow Y, black S and white W are entered in a specific order.
  • This binding cartridge regulates the insertion of the weft threads and the movement of the warp threads (up and down). The binding takes place in accordance with the pixels generated during the color separation of the representation. As shown in Fig. 5, a red and a green pixel are to be created in the tissue.
  • the warp thread K1 is in the low compartment and the other warp threads in the high shed, so that after the red weft thread has tied, the warp thread K1 and the green weft thread crosses the warp thread K2 above (Fig. 6 and 7).
  • Several weft threads with different colors can also be tied in the same way in order to obtain a color mixture or shade.
  • the weft threads 11 float on the back of the fabric. It is also possible for the weft threads 11 to float on the face of the fabric. In order to improve the fabric structure, the float length of the weft threads is limited by a minimum of four warp threads 12 on the back or a maximum of forty-eight warp threads 12 on the face side.
  • the weft threads in the fabric are tied off by a regular weave.
  • the method comprises an image preparation 1, an image decomposition 2, a weaving program creation 3 and the weaving 4.
  • image preparation image data in a TIFF file format are scanned from a template, for example a photograph a program for the Image processing read in and displayed on a screen as an image of the representation to be woven.
  • a template for example a photograph a program for the Image processing read in and displayed on a screen as an image of the representation to be woven.
  • the image that appears on the screen has several thousand colors or tones.
  • the image is broken down based on what is displayed on the screen.
  • the basic colors cyan C, magenta M, yellow Y and black S are selected, which are used for weaving.
  • the image colors are then broken down into the basic colors and stored in pixels with a color depth of 8 bits for each basic color in a separate bitmap 6.
  • the color depth is then reduced to 2 bits, which forms a square pixel.
  • the gray levels are broken down into basic colors C, M, Y, S or white 0 and thus the basic color of the pixel is determined.
  • the bitmaps of the basic colors are offset by one pixel in the weft direction and put together on a further bitmap 7.
  • the weft sequence of the weft threads in the basic colors cyan, magenta, yellow, black and white is determined at the same time. These data are read into a CAD system 8 in a TIFF file format and displayed on the screen.
  • a weaving program for the jacquard weaving machine is created from this data, which provides for the use of irregular weaves without repeating weave repeats.
  • the ties are determined on the basis of the data read in and including a warp / weft ratio.
  • the data are represented as square pixels and transferred to a sample card 9, which show the pixels as square pixels of the display to be woven on the screen.
  • the weaving map 10 is then created, on the basis of which the jacquard weaving machine is controlled.
  • weft threads 11 are inserted in the weft sequence cyan, magenta, yellow, black and white as a thread group in a weft line.
  • the weft threads are tied by warp threads 12 in a cell, which by a binding is formed by two warp threads and at least two weft threads without repeat repetition.
  • FIG. 10 shows a binding cartridge for the fabric to be produced, which is derived from the weaving program.
  • This binding cartridge regulates the insertion of the weft threads and the movement of the warp threads (up and down).
  • the binding takes place in accordance with the pixels generated during the color decomposition of the representation.
  • a pixel with the base color cyan and one with the base color magenta are to be generated in the tissue.
  • the warp thread K1 is in the deep compartment and the other warp threads are in the high compartment, so that after the weft thread with the basic color magenta has been tied, the warp thread K3 crosses above (Fig. 11 and Fig. 12).
  • Several weft threads with different colors can also be tied in the same way in order to obtain a color mixture or shade.
