Singer 5x90 Needles for Sewing Machines

Knitting needles for Singer home sewing machines, 5 pcs, strength 90

Knitted needles. The spherical needle needles have a rounder tip, which prevents the meshes from creeping and tearing, as they pass between the fibers.

Singer needles for sewing machines have a color marking of the needle type on the shaft:
 
 Metallic (for metallic threads - without color marking), Quilting (for quilting - purple marking), Universal (universal for all fabrics - red marking), Overlock 14SH (for overlocks - without color marking), Microtex (for microfiber, silk - black marking), Jeans (for denim - blue marking), Leather (for leather and imitation leather - brown marking), Hemstitch (for hemming - without color marking), Embroidery (for embroidery machines - white marking), Stretch (for knitwear - yellow marking) , Overlock 14U (for overlocks - unmarked).
 
 Furthermore, the needles are marked in color, according to the strength of the needle (needle size). The designation 100 corresponds to a needle width of 1 mm. The designations are as follows:
 
 60/08 (without color marking), 70/09 (green marking), 80/12 (orange marking), 90/14 (blue marking), 100/16 (purple marking), 110/18 (yellow marking), 130 / 21 (red marking).
 
 We choose the needle strength with regard to the type of material. The thread must always pass easily through the needle, it must not jam.
 
 - Light and thin materials require thin needles, then we choose thin threads
 - Thick materials require thicker needles, then we can choose thicker threads

Singer recommends changing the needle after 6 - 8 hours of sewing (sewing hours), this time is recommended and depends on the type of fabric.
