Methods for unraveling knitted fabrics and a machine for unraveling knitted fabrics in order to reuse the yarns of a knitted fabric to be unraveled; the methods providing that the yarns can be unraveled either by stretching and loosening the yarns or by twisting the yarn plies onto each other whatever the knit type and the number of yarns are and the methods having stretching-loosening and twisting characteristics. The machine for unraveling knitted fabrics operates by the use of the methods and includes units for unraveling knitted fabrics in a desired number, each of the units consisting of yarn guide passages, yarn feeders, a yarn winding unit, an optionally stretchable tension/reservoir arm wherein the position of the arm is detected by a sensor, and a mechanism for twisting yarns with plies, the yarn feeders and the yarn winding unit being able to rotate in two directions and being actuated by motors, the machine being able to unravel the yarns by controlling its own units individually or together in a particular number thereof, and determining that the yarns are loosened/stretched and determining the knit order via a control unit.
