METHOD AND APPARATUS FOR PRODUCTION OF YARN THREAD Russian patent published in 2021 - IPC D01H13/04 

FIELD: yarns.

SUBSTANCE: invention relates to a method of production of a single yarn thread (3) formed by twisting at least two separate fibers (2a-2c). At the first stage of the method, at least two separate twistable fibers (2a-2c) are provided to form said one produced yarn thread (3). Said at least two provided fibers (2a-2c) are then fed into a spinning apparatus (6) comprising at least one element (10) in form of a spindle or bobbin, using a guiding apparatus (5) comprising multiple cylinder-like or cylindrical guiding elements (5a-5e). Said fed fibers (2a, 2b) are then twisted in the spinning apparatus (6) forming said one produced yarn thread (3). Said at least two fibers (2a, 2b) are therein fed into the spinning apparatus (6) by means of at least two separate cylinder-like or cylindrical guiding elements (5d, 5e) arranged so as to be spatially separated from each other in at least one spatial direction. The invention also relates to a yarn thread produced by the described method, a textile article containing a yarn thread and an apparatus for production of the thread.

EFFECT: invention allows to produce yarn threads exhibiting lower tendency to form neps and lower hairiness compared to previous technology.
