The 38 (R) needle (needle system 38) 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 Dürkopp Adler (classes 100-69, 527i-811, 527i-847, 550-867), Pfaff (classes 38 BIS 1937, 39 BIS 1937, 1245, 1295) and Rimoldi (classes 229 ALL CLASSES, 421 OTHER CLASS, 530 ALL CLASSES, 840 - 104).
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 medium-weight standard woven and knit fabrics for everyday garment production. 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).
