step jacquard

[attachment=18088]

The main steps of designing and fabricating the pattern card of rich color image are:

A. Adjust the light-shade gradation of target image displayed in the computer and on the chromatogram, configure several colors to conduct color clustering as required;

B. Conduct color segmentation according to the configuration in the above-mentioned step A and combine with black & white into plentiful color combination, then input texture of pattern card successively as per light-shade relation.

C. Save the above-mentioned design to a pattern card file.

A step between B and C may be added that the pattern cards of several colors clustered in B should be stringed and combined to weave more colored fabric.

In pattern card fabrication, computerized image color clustering is adopted. Firstly cut down image colors to only several colors and then conduct color combination. As above said, color combination can provide more than a thousand of colors and these combined colors can form a lifelike weaving image to a verisimilitude extent greatly higher than common color jacquard with just scores of colors. Since the method needs only several kinds of color yarn (some tendentious color yarns may be added if needed), the fabric is characterized by easy fabrication, simple operation and freewill color combination.

The main steps of fabricating auxiliary pattern card are:

A. Conduct skeleton edge enhancement of auxiliary pattern according to design requirements and paint different colors onto different texture. The color of figure flat painting shall be identical to the color of edge enhancement. The color filled in edge enhancement may be selected at will so long as different colors are painted for different texture to show the distinction.

B. Add interlacing points at figure flat painting with non simple circulating texture, that is, if no simple circulating texture is represented at figure flat painting, interlacing points should be necessarily added to limit overlong warp or filling yarn floats and simultaneously enhance expressive force. This kind of interlacing points consist of plate interlacing, cis interlacing and fancy interlacing as required, while manual interlacing should adopt cis interlacing and fancy interlacing to preferably embody jacquard characteristics.



The steps of said loom preparation are as follows:
(1) Use one color yarn as warp or filling yarn from several color or black/white yarns required by the design, with other color yarns as the other yarn left in warp or filling yarn, and conduct the processes of warp beaming and cop winding;

(2) Adjust looming parameters according to varieties and specifications, such as the size, density and silk yarn variety.

Said steps of looming and weaving are:

install the finished pattern card in the loom and start the loom to fabricate the color jacquard fabric of different design characteristics.

Said motif image relates to the image to design the pattern card in accordance with computerized color clustering. Both motif image and auxiliary pattern do not depend on their locations or occupied areas but depend on the means of forming, and the locations and occupied areas of both motif image and auxiliary pattern can be interchanged.

The advantages of this invention lie in that the fabrics produced by this invention can represent not only the beauty like manual interlacing but also the vivid and beautiful color interweaving effect of texture produced by computer software, namely, simultaneously representing: strong dimensional style of manual designed pattern, vivid shaping and rich color patterns designed by the method of computerized color clustering; patterns of fabrics are jointed skillfully, displaying colorful, vivid and lifelike picture with high ornamental value.
