    Abstract: A method of producing at least one yarn formed by spinning at least two individual fibers, comprising the following steps: providing at least two individual fibers, to be spun to form the at least one yarn to be produced, feeding the at least two provided fibers to a spinning device comprising at least one spindle element or bobbin element via a guide device comprising a plurality of, in particular cylinder-like or cylindrical, guide elements, spinning the fed fibers in the spinning device, forming the at least one yarn to be produced, wherein the at least two individual fibers are fed to the spinning device via at least two separate, in particular cylinder-like or cylindrical, guide elements that are arranged such that they are spatially separated from one another in at least one spatial direction.

    Abstract: A method for making an elastic core yarn includes covering an elastic core having a fiber of natural rubber with metric count 200-1000 dtex with a cotton-based covering yarn. The elastic core and the covering yarn are conveyed such that the covering yarn laterally attains a proximity of the elastic core in a wrapping space. The covering yarn is helically wrapped about the elastic core. The conveying speed, and therefore the winding/unwinding speed, is selected such that the elastic core is stretched to a stretching ratio of at least two, and the covering yarn becomes twisted with a final twist direction opposite to its initial twist direction, and forms T coils per length unit of the elastic fiber set between a minimum value T0 and a maximum value T1. An elasticized yarn is thereby obtained, and a fabric, in particular a denim type fabric, is manufactured from this yarn.
