FIELD: sports equipment. SUBSTANCE: string has core including at least two complex threads, which are composed of polyamide filaments twisted to form spiral thread, with coil space being within 15-120 mm, and enclosure made from polymeric material. Each complex has sheath containing polymeric binder. Complex threads are bound with polymeric binder and twisted into spiral, with coil space being within 20-70 mm and thread linear density of 29-187 tex. Ratio of polymeric binder and complex threads is within the range of 1: 40 to 1:5. Method involves tightening threads; forming belt from spaced threads; impregnating with polymeric binder; calibrating in spinneret and cooling under tension. Prior to introducing into spinneret, belt is subjected to spiral twisting with coil space of 15-120 mm and heating to temperature of 135-165 C in synchronism with tensioning for value of 80-220 H. EFFECT: increased efficiency, improved quality of strings. 3 cl, 1 dwg, 2 tbl
