With the SINCRO FFM - PREMIUM and SINCRO T FFM - PREMIUM machines, it is possible to produce FAPP™ packages (FAdis Precision Package) with a low density, which allow retraction margins of the yarn during the dyeing phase, thus keeping a good residual elasticity percentage of the elasticized yarn.
Thanks to this more and more evolved technology, it is possible to process not only stretch polyamide yarns, but also all those elasticized yarns whose main prerogative is to maintain a high degree of residual elasticity after dyeing, such as for example, elasticized viscose, nylon PBT, polyester T400 and other similar yarns.
