The UY 133 GS SES needle (needle system UY 133 GS) has a small ball point for working knit fabrics, without damaging the loops. It is used in industrial chainstitch and general-purpose sewing machines. Suitable machine classes are found, among others, at Union Special (classes 54200 AZ 2 12 529, 54200 K, 54200 KA, 54200 KAZ 643), Rimoldi (classes 174, 176, 174 - 10- 4LL- 01, 176 ALL CLASSES) and Productos Sigma (classes B).
The available needle sizes are used, among others, for heavy, dense knit fabrics and technical knits. As sewing thread, a matching thickness is usually recommended depending on the needle size chosen, e.g. from Amann Serafil or Rasant; for very stretchy seams, a texturised thread also works well. The ball point glides between the loops instead of piercing them, keeping the seam clean and undamaged.
