The DSW Jet offers vast potential for optimising existing machines. On the one hand, considerable air savings of up to 30% can be achieved in the DSY (differential shrinkage yarn) process. Combining FDY and POY yarn makes it possible to create interesting structural effects in the fabric. On the other hand, a higher number of knots as well as knot uniformity with the same air consumption can be achieved in the DW draw-packaging process for plain yarns when POY or FDY yarns are combined.
