The work devoted to complex research of the pro­duction technology of reinforced sewing threads 35 LL. These threads consist from two core-spun polyes­ter yarns of linear density 16,7 tex.

Machine setting parameters were recommended for improving the quality of core-spun yarns for sew­ing threads manufacturing. The influence of ring spinning machine settings parameters on core-spun yarns properties was determined. It was recognized that the substantial increase of the yarn quality is achieved by reduction of slivers and rovings linear densities . The optimal range of the input tension of polyester filament yarn in the core-spun yarns pro­duction was determined.

The trials of produced sewing thread have proven the efficiency of the developed recommendations.

Complex research of work of spinning eqiupment by manufacturing of reinforced sewing threads
