TWISTED REINFORCED THREAD MANUFACTURE METHOD Russian patent published in 1997 - IPC

FIELD: textile industry, in particular, production of thread for sewing industry, shoes making, knitted product industry, rubber product manufacture and polygraphy. SUBSTANCE: method involves forming single reinforced threads on spinning machine by winding filaments of required length around synthetic core filament to form sheath about it; rewinding and slubbing single reinforced threads and twisting them in direction opposed to that of single reinforced thread. Prior to forming single reinforced threads, their sheaths are treated with nonconductive compound promoting cohesiveness of sheath filaments with synthetic core filament. Winding of sheathing filaments about synthetic core filament is effectuated with twisting coefficient of 28-31. Slubbed single reinforced threads are twisted at twisting coefficient 1-11% below or equal to that of single reinforced thread. EFFECT: increased efficiency, simplified method and improved quality of thread. 2 tbl
