  • Patent number: 10662558
    Abstract: A method for producing a double jersey fabric on a double jersey, single jacquard circular knitting machine includes steps of knitting a front side of the fabric on a cylinder (C) and knitting the rear side of the fabric on a dial (D) of the machine, knitting a base yarn on a rear side of the fabric, except for connecting points where the base yarn is knitted on the front side of the fabric. The method additionally includes steps of inserting a pattern yarn before a start of a pattern unit, which is produced using the pattern yarn, knitting the pattern yarn on the front side of the fabric in the pattern unit and cutting off the pattern yarn after the pattern unit.
