The needle of system DIX1 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 Juki (classes LK, LU, LUH, LK - 1850 G), Happo (classes DI, DI - 4 A, DI - 4 C, DI - 6 A) and Seiko (classes D, DI, TE, D - 1 ALL CLASSES).
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).
