ABSTRACT
This chapter provides information about the warp knitting process, limited to the patterning related topics. Each warp yarn, used for production of warp knitted fabrics, is formed from a single guide. For the graphical notation of the warp knitted structures, the complete motion process of the guides is recorded symbolically on paper. During the knitting process, the guide moves between the needles and this motion step is named “swing in”-the needles motion. The run-in influences the stability of the knitting process and the appearance of the fabrics significantly, because it determines the yarn tension during the knitting and the following relaxation processes directly. After the knitting process the fabric relaxes and passes the thermofixation process, which determines its final density of wales and courses per unit length. The repeat of the threading is as well important, especially if the different guides have partial threading or threading with different colours or materials.
