The UY 113 GS SES needle (needle system UY 113 GS) has a small ball point for working knit fabrics, without damaging the loops. In the SERV 7 version, it also offers increased needle stability for secure seams. It is used in industrial overlock, coverstitch and safety-stitch machines for elastic knit fabrics. Suitable machine classes are found, among others, at Rimoldi (classes 066, 264, 066 - 01 ALL CLASSES, 066 - 11- 09 TO 26), Renown (classes 22, 25, 26, 41) and Gemsy (classes GEM-1404, GEM-1404PL, GEM-1404PMD, GEM-1404PTV).
Thinner needle sizes are used, among others, for medium-weight knit fabrics for everyday garment production, and the thicker versions 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.
