DIGITAL DESIGN OF JACQUARD WEAVES BASED ON ARAHWEAVE

Summary/Abstract: Arahne is a software company specialized in developing CAD/CAM textile weaving software. Its three products, ArahPaint, ArahWeave and ArahDrape as a complete package serve in weaving industry since 1992. These programs help from drawing in seamless repeat pattern and in fabric density (ArahPaint), to dobby and jacquard weaving (ArahWeave) and to apply a fabric texture or simulation over a photo of an existing final product (ArahDrape). The designing of weave structures is influenced by the characteristics of the fibers, the manner of arrangement of fibers in yarn, the different type of weave structures and fabric surface finishes. ArahWeave is a very powerful program, which immediately allows the realistic visualization of the fabric simulation, both in 2D and 3D format, for any change of structural fabric characteristics (weaves, threads pattern, yarns, colors, regulator, denting, variable density etc.). In this paper, the authors present the structural design methods for the jacquard simple and compound structures, with monochromatic and multi-colored effects, by exploiting ArahWeave program. When a fabric is woven with a particular weave structure using two or more colors in a particular pattern, a color and weave effect is produced. Multi-colored effects in a jacquard weave structure require of more than one system of yarns in the warp and weft and reveal multiple warp or weft colors. Color and weave effects allow to observe the effect that a color plan, namely the order of warping and the order of wafting, will produce for a given weave structure. ArahWeave program serves as a useful experimental tool in assessing of the color expression in designing of the ornamental textile fabrics, before setting up a jacquard loom.
