CAD APPLICATION FOR SIMPLE WOVEN FABRICS DESIGN
CAD APPLICATION FOR SIMPLE WOVEN FABRICS DESIGN

Summary/Abstract: Most existing woven fabrics on the market are “simple woven fabrics” (with a single warp/weft system). In the last decades, multiple companies have developed CAD/CAM applications that facilitate the designing and weaving process of this type of woven fabric (Dobby Designer from Apso, Dobby Designer from ScotWeave, ProWeave from Pointcarre, Design Dobby from Textronic etc.). This paper presents an original application for designing simple woven fabrics (TexD), developed by researchers from the Faculty of Textile, Leather and Industrial Management of Iasi. Unlike the existing applications mentioned earlier in which the weave is graphically built (point by point or as a result of combining the draft and lifting plan), TexD has an underlying analytical method which mathematically generates the weave using simple vector-based algorithms. This method allows for an instant and error-free generation of the weave design, which is time-saving and reduces the need of workforce. Based on a generated weave, a draft (with minimum number of shafts needed) and lift plan are also automatically provided. TexD can combine multiple different generating algorithms based on the direction of the warp/weft, which leads to obtaining complicated and distinctive designs while maintaining a low number of shafts. The application allows for colour management and contains essential design tools such as mirror, flip and reverse cloth. TexD has been used as a teaching tool at the Faculty of Textile-Leather and Industrial Management of Iasi for many years to great effect. Both the underlying method and the application itself are simple to understand and use and it is proven to incentivise creativity in students.
