The document discusses several types of software used for textile and fabric simulation and design. It describes programs for simulating weaving patterns and colors, developing technical textiles, simulating knitting at the yarn level for computer graphics, and optimizing setup of textile production machinery. It also mentions software for jacquard weaving design, dobby loom planning, knitting simulation, yarn scheduling simulation, and braiding machine configuration. The software aims to reduce costs and improve efficiency in textile design and manufacturing.
