METHOD FOR MANUFACTURE OF TWISTED REINFORCED THREAD Russian patent published in 2006 - IPC D02G3/38 

FIELD: textile industry, in particular, manufacture of twisted reinforced thread.

SUBSTANCE: method involves introducing two non-twisted complex threads into fibrous flow of semi-finished product obtained in the process of drawing by means of drawer of ring spinning machine; determining distance between threads by multiplying empiric coefficient of 0.7-1.3 by partial of dividing the value of linear density of joining thread (tex) by value of linear density of joining thread fiber (tex), said values being multiplied by diameter of joining thread fiber (mm); in formed twisting triangle, twisting threads together with joining thread while dividing joining thread fibers into two parts to produce reinforced components, which are in their turn twisted together with each other.

EFFECT: improved physico-mechanical properties of threads owing to creating homogeneous elastoplastic composition, and increased wear-resistance of thread.
