Simulation

From a quality standpoint, DesignScope® victor offers one of the best simulations for woven fabrics available in the market today. Years ago, EAT (as one of the first CAD/CAM suppliers) had based their simulation program on a full JC file. JC files contain all information for the control of jacquard weaving loom combinations. The JC formats are better known under the name of the machine manufacturers, such as Stäubli, Bonas, Grosse, Schleicher etc. The simulation module mirrors the entire complex process of weaving. This idea has been captured in EAT's Think-Tank.

Control functions such as active hooks, thread densities, thread sequences, etc. are taken into account, as well as thread qualities, materials and colors. Respecting all these parameters, in addition to the reed draw-in and the up/down information for the shed, the module determines the dynamic behavior and the progression of all thread systems and then corrects them to capture the real product. The image file created by that process is then displayed on the monitor and may be printed out at the user's discretion. Quick Repeat can be used in this module, and a Microsoft Word file can be generated and printed out for documentation purposes.

To define the yarns used in a simulation, EAT does not scan the actual yarn. Yarns are created within the EAT software and are stored in a yarn database as an archive. This database offers the definition of all kinds of yarns, from simple ones all the way to complex novelty yarns with substantially different color mixes. Novelty effects and color mixes may be distributed among the yarn in defined length segments (e.g. 0.5 m, 1 m, 20 m, 100 m etc.) or in random mode. All individual threads defined in this way can then be twisted together to create a plied yarn with user-defined twists per a certain length unit. The advantage of this process is visible in the actual fabric simulation. Opposed to a scanned yarn, this method does not create any repeat defects that don?t happen in the real woven sample. In addition, all defined yarn colors and colorways can be modified without recalculation of the simulation. This is extremely important when developing different colorways of a design. To get a more accurate visual impression of a developed yarn, DesignScope® victor software offers isolated displays of threads or yarns: single, plied or even simulated in a small area using with a selected base weave and warp weft size.

The newest development in EAT's simulation module right now is the terry simulation. With the demand for high-quality standards, EAT actually succeeded to derive the complete loop development from the JC information of terry jacquard looms. This also includes variable pile lengths. Therefore, EAT does not display previously set standard loop effects like other CAD/CAM manufacturers may need to.
