Method of Fabricating Color Jacquard Fabric

Abstract

This invention discloses a method of fabricating color jacquard fabric, comprising the processes of design and fabrication of pattern card, loom preparation, looming and weaving. The steps of design and fabrication of pattern card are: reading target image for jacquard into a computer; adjusting the image and setting parameters; selecting pixel value according to image dimensions; modifying the image; dividing the modified target image into motif image and auxiliary pattern around the motif image, designing and making the pattern card of motif image and auxiliary pattern of different design characteristics by jacquard design software; and finally combining said two pattern cards into a pattern card that represents the image and pattern of different characteristics in one fabric with corresponding warp and filling yarns. The invention can provide vivid lifelike picture of fabric, integrating rich color representation and artful pattern.

DETAILED DESCRIPTION OF THE INVENTION

Embodiment: making a color scenery picture to a color jacquard photograph 27 cm wide and 20 cm high with framed and edging pattern. The design uses 3000 warp yarns (white) that adopt 2/22.2/24.4 dtex mulberry silk and 4000 filling yarns (scarlet, yellow mid, cyan blue and black) that adopt 40 dtex color nylon yarn. As shown in FIG. 1, the operating steps are:

• • 1. Scan a color scenery picture (as shown in FIG. 2 and FIG. 4) with a color scanner connected to a computer, beginning with a preview;
  • 2. Adjust scanning parameters according to the image of preview. In the case of 300 dpi resolution, the warp (longitudinal) pixels should be 3485 and weft (lateral) pixels 2450;
  • 3. Adjust the color, brightness and contrast of the image scanned. Then make scanning and save the image in a disk; 4.Scan the edging pattern (as shown in FIG. 2 and FIG. 3) designed for frame and save the image in a disk;
  • 5. Open professional computer-aided design software and conduct combined image design, mainly including image design, adjustment, treatment, cropping and despeckle, so as to ensure part of scenery picture to be positioned in the framed pattern, then adjust the combined image dimensions to 3000×2100 pixels;
  • 6. After adjusting image dimensions, conduct color separation on scenery part in four procedures to obtain four color separation files (scarlet, yellow mid, cyan blue and black);
  • 7. Open said image files in CAD software and conduct pattern card fabrication. For example, open red color separated image file in CAD software to configure it to several transitional textures from red to white. Then conduct such processes to yellow, blue and black color separated image files. As a result, every set of warp and filling yarns weaving constitutes a set of solid color pattern card with the variation of light and shade;
  • 8. Combine said four pattern cards in the order of scarlet, yellow mid, cyan blue and black with the identical order to correspondent wefting yarns. If needed, the four color pattern cards can be stringed and combined in this step;
  • 9. Open the file of edging pattern designed for frame and conduct pattern card fabrication;
  • 10. Conduct skeleton edge enhancement of pattern design and paint different colors onto different texture of frame pattern. For example, if there are two textures of frame pattern design and a ground weave, white may be applied to ground weave, tangerine to pattern design A and golf green to pattern design B. Tangerine and golf green may be configured separately as a set of warp figure comprising mainly warp float and weft figure comprising mainly weft float. If figure flat painting is not simple circulating texture, manual yarn interlacing treatment may be conducted in design as needed with identical coloring of figure flat painting and skeleton edge enhancement;
  • 11. Make the pattern card in accordance with the pattern design and texture configuration;
  • 12. Combine the pattern cards made from step 5 to 7 and the pattern card made from step 8 to 11 to form a complete pattern card file, namely the combining of two matching pattern cards with precise coordination of order and structure at the joint of two pattern cards;
  • 13. Finally input fabricated pattern card and relevant parameters in electronic jacquard loom for later use;
  • 14. Install warp yarns and weft yarns. For warp yarns, adopt 3000 white mulberry silk yarns arranged in a density of 111 yarns per cm. For weft yarns, adopt scarlet, yellow mid, cyan blue and black nylon yarns with wefting order identical to correspondent pattern cards and arranged in a density of 50 yarns per cm×4 sets;
  • 15. Start loom to weave a jacquard fabric that represents not only elegant sense of reality embodied by manual design cis interlacing but also rich color and lifelike scenery picture.
