FIELD: textiles, paper.
SUBSTANCE: invention relates to light industry and relates to cords of cellulose multifilament yarns with increased titre of individual elementary yarn. The cord comprises the cellulose multifilament yarn, has a strength of at least 35 cN/tex, and the individual elementary yarns of the multifilament yarn have a titre of at least 2.3 dtex. The structure of the cord with a twist factor is Tf=185 during fatigue test with the use of a disc with the settings of compression/expansion of -20/+2%, and the number of cycles equal to 855.000 performed and evaluated according to ASTM D 6588, it has at least 1.1 times higher fatigue resistance than that of the cord with the same twist coefficient and with the titre of individual elementary yarn equal ≤2.0 dtex.
EFFECT: invention provides a cord with improved fatigue properties, ie higher fatigue resistance than the conventional cords with the titre of individual elementary yarn of 1 to 2 dtex.
