The needle of system UY 118 GAS has a normal round point for working woven and knit fabrics. It is used in industrial overlock, coverstitch and safety-stitch machines. Suitable machine classes are found, among others, at Yamato (classes FD, FD - 62 -01MR, FD - 62 -01MS, FD - 62 -02MR), Union Special (classes 35800 A, 35800 AA, 35800 AH, 35800 AJ) and Brother (classes FD6, FD6 - B 941, FD6 - B 942).
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).
