The needle of system B-27 has a normal round point for working woven and knit fabrics. It is used in industrial chainstitch and general-purpose sewing machines for everyday garment and textile manufacturing. Suitable machine classes are found, among others, at Siruba (classes 401, 504, 505F1-04, 512 bis 514), Kingtex (classes SH, SHF, SK, SH-7002-032-M02) and Yamato (classes 74 Series, 78 Series, AEF, AFZ).
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).
This needle also has a nickel-Teflon (NIT) coating: a special anti-adhesive coating with excellent sliding properties, high abrasion resistance and high corrosion resistance.
