The needle of system UY 163 GAS 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 Kansai (classes MAC-100, PX-301-2S, PX-302-4W, PX-302-5W), Global (classes 1102, 1112, 1162, 5302) and Union Special (classes 53100, 53300, 53400, 53100 OTHER CLASS).
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).
