The needle of system 135X17 has a normal round point for working woven and knit fabrics. In the SERV 7 version, it also offers increased needle stability for secure seams. 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 ACF, ALS, AMS, APW), Brother (classes BAS -300E, BAS -311A, BAS -311E, BAS -311EL) and Singer (classes 61, 107, 111, 112).
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 (polyester) or Rasant (polyester/cotton).
