The needle of system 328 FL-E has a normal round point for working woven and knit fabrics. It is used in industrial lockstitch and general-purpose sewing machines for everyday garment and textile manufacturing. Suitable machine classes are found, among others, at H.J.Dahmen Steppomat-Textilmaschinen (classes ECOMAT, ECOMAT SERIE ET DOPPELNAHT AUbisM, STEPPOMAT SERIE G, STEPPOMAT SERIE GT DOPPELNAHT AUbisM) and Dahmen (classes ECOMAT, ECOMAT SERIE ET DOPPELNAHT AUTOM, STEPPOMAT SERIE G ALL CLASSES, STEPPOMAT SERIE GT DOPPELNAHT AUTOM).
Thinner needle sizes are used, among others, for light, fine woven and knit fabrics such as blouse and shirt fabrics, and the thicker versions for heavy, multi-layer woven and knit fabrics as well as technical textiles. As sewing thread, a matching thickness is usually recommended depending on the needle size chosen, e.g. from Amann Serafil or Rasant (polyester).
