Sergers Mastering Your BERNINA® Needle Chart Never use a needle bigger than size 90/14 in your serger; larger needles can interfere with looper movement and cause damage. Ball Point 70-90 Has a rounded point. 70 for lingerie, nylon, jersey; 80 for T-shirt; 90 for sweatshirt fleece. Stretch 70-90 A stretch needle has a more rounded point and a blue anti-cling coating which helps to prevent skipped stitches in knits and elastic. Sometimes used on Ultrasuede®, vinyl, and plastic. Universal 60-90 A compromise between a sharp and a ballpoint needle; can be used on both wovens and knits. 60 - very fine batiste 70 - broadcloth 80 - trigger and gabardine 90 - denim and twill Jeans 70-90 Has a sharp point and a shaft that is less prone to flex. The sharpness of the needles makes it better for use on denim and woven fabrics where a clean stitch is desired. Microtex 60-90 Sharp (Schmetz) A sharp point with a thin shaft. 60-90 corresponds to the weight of the fabric; as the fabric gets heavier or denser, the number is higher. Specially designed for microfiber fabrics. Microfiber assort'd The thin, tapered point of this needle causes less (Lammertz) (75 & 90) damage to fabric when seaming and cross seaming. Quilting Topstitch 80-90 A sharp point with a large eye and deep groove. Use with heavier fabrics - the large groove cradles heavy threads. Embroidery 75-90 (Schmetz) Metafil (Lammertz) Sharp needle with a large eye and groove; also has a coating and a larger scarf. For use with embroidery thread - prevents shredding of rayon or metallic threads. Two threads may be used through the eye of an 80 or 90 needle. Leather 80-90 Point is a sharp cutting wedge. Used for leather only. Not for vinyl or simulated leathers. MASTERING YOUR BERNINA® SERGERS 6/2006 7 ©2006 BERNINA® of America, Inc.
