CAD FOR JACQUARD WEAVE<br />
For do<strong>in</strong>g jacquard, CAD is a production necessity. Complicated patterns and picture<br />
effects are made possible by the computer programme <strong>in</strong>struct<strong>in</strong>g the loom to move the<br />
threads <strong>in</strong>to new positions. The traditional jacquard design<strong>in</strong>g starts with the conversion<br />
<strong>of</strong> a sketch or design concept <strong>in</strong>to a po<strong>in</strong>t paper rendition <strong>of</strong> the pattern. Grids on po<strong>in</strong>t<br />
paper represents wrap & weft yarns <strong>of</strong> a fabric. A designer pa<strong>in</strong>ts the design concept with<br />
complex weave effects. This whole process takes several days before complete design<br />
concept pa<strong>in</strong>ted on square graph paper. After the po<strong>in</strong>t paper is completed a card cutter<br />
read the po<strong>in</strong>t paper l<strong>in</strong>e by l<strong>in</strong>e and then translates it <strong>in</strong>to a jacquard card, us<strong>in</strong>g a card<br />
punch<strong>in</strong>g mach<strong>in</strong>e. Production <strong>of</strong> a jacquard from the start <strong>of</strong> the po<strong>in</strong>t paper pa<strong>in</strong>t<strong>in</strong>g<br />
process through to the production <strong>of</strong> the jacquard card set <strong>of</strong>ten requires at least 2-3<br />
weeks, even then there is always possibility <strong>of</strong> manual errors <strong>in</strong> design, pa<strong>in</strong>t<strong>in</strong>g & card<br />

Process <strong>of</strong> jacquard design<strong>in</strong>g by CAD/CAM<br />
In the Jacquard design <strong>system</strong>, a s<strong>of</strong>tware package is developed to represent the warps &<br />
wefts <strong>in</strong> graphical form on the monitors screen. The very first step to create the jacquard<br />
design is to choose the motif. It can be get by scann<strong>in</strong>g the art work or draw<strong>in</strong>g a outl<strong>in</strong>e<br />
<strong>of</strong> a picture. The various tools present <strong>in</strong> computer s<strong>of</strong>tware helps to make a beautiful<br />
design <strong>in</strong> just no time. The design is edited now to make it perfect as required and can be<br />
set <strong>in</strong>to desired repeat, color & size.<br />
It may be required to fit <strong>in</strong> a particular number <strong>of</strong> hooks and picks. Every four sides <strong>of</strong><br />
motif may be checked for a match etc. After this the process depends on application. A<br />
jacquard designer may <strong>in</strong>troduce the weaves (b<strong>in</strong>d<strong>in</strong>gs) on each <strong>of</strong> the colors <strong>in</strong> the<br />
design. The designers just have to specify the weaves. The s<strong>of</strong>tware <strong>of</strong> CAD
