Q. In a circular knitting machine what kind of needle is used?

Latch needles are designed to be used in circular knitting machines. While most circular knitting machines only employ a single type of latch needle an interlock machine uses two. Instead of two cylinders for two sets of needles and sinkers like in a double jersey machine a single jersey machine just has one cylinder. Single-jersey machines employ knitting-machine needles and sinkers while double-jersey machines have needles organized in both the cylinder and the dial. For instance this prevents the need for side seams when sewing shirts using body size machines. Circular knitting is typically used for making outerwear like T-shirts as well as leisure and athletics lingerie and sleepwear like bra materials and technological textiles like smart shirts.
