Warp and weft patterns

To make our program easy and natural for both experienced textile designers, as creative designers not too familiar with weaving, we provide two ways of entering warp and weft pattern. Creative designers will click on the the yarn with mouse and draw the pattern directly in the fabric simulation. An experienced designer will prefer to write the warp/weft pattern in numerical way since he/she has precise ideas about what he/she wants to do and will not want to lose time by accurate mouse clicking (although zoom is available).

• Up to 25 different yarns in warp and 25 in weft can be used simultaneously.
• You can easily design patterns with up to 65520 threads.
• Besides drawing warp/weft pattern with mouse, you can also insert or delete threads anywhere in the pattern with mouse.
• If the user is drawing the warp/weft pattern with mouse, the program automatically rewrites the numerical warp/weft pattern.
• If the warp/weft is written in numerical way, it can be written as number of threads (2A 4B 2A 6C) or as length in millimeters (0.5A 1B 0.5A 1.5C) or sixteenths of inch. Conversion from number of threads to millimeters (inch/16) and vice versa is automatic.
• Two types of parenthesis are supported for entry of repeating patterns: 2a 10(1b 2c) - repeat 1b 2c 10 times; and 2a 10[1b 2c] - repeat 1b 2c until you use 10 threads. Nesting of parenthesis is allowed.
• Conversion of fabric from one density to another, and keeping the same repeat size is automatic
• Generation of a square design (e.g. tartan) with different density in warp and in weft is automatic
• It is possible to move warp/weft pattern by 1 or 8 threads in any direction, or to mirror it
• Fringe option permits view and print out edge of just warp (bottom) and weft (left) besides design, just like in real fabric. It looks like this.
• Sort option will rewrite the pattern so that it starts with yarn A, followed by B, etc., as this is required by production department of many mills.
• A special function enables you to split (or merge) weft across several weft selectors.
• Support for design of fabrics with two warp beams
• Double weft insertion support
• Loading, graphical browsing and saving warp or weft patterns
• Tools: editing decomposed, the Pattern generator, resizing warp/weft pattern, remapping yarns

This is how the warp and weft pattern editor looks:

Centering of the the warp or weft pattern according to total number of threads in the fabric width, or blanket width. You can center it manually or automatically.

The Editing decomposed function opens a whole new world to the "complicated" warp or weft patterns. It enables to divide the pattern by different criteria (custom, denting, two warp), which drastically reduced the time needed for writing a new pattern, or changing already created pattern.
Double face fabrics? No problem.
The following picture shows double layer weave in the Weave editor. We want to have one plaid fabric with twill weave on the top, and a different one on the back.

So, how to write a pattern for both sides, face and back? Open the Edit decomposed window from the Tools menu of the Edit warp and weft pattern window. You need to write pattern for the face fabric, and then pattern for the back fabric; both are quite simple. Program will automatically combine both patterns into one warp pattern. Of course, you also need to do this for the weft.

Below is the fabric simulation of the blanket; first the face side...

...and this is the back.
