METHOD FOR TREATMENT OF ARAMID MONOFIL, MONOFIL, MONOFIL ROPE, ARTICLE, METHOD FOR ARTICLE PRODUCTION, PNEUMATIC TIRE CASING Russian patent published in 1998 - IPC

FIELD: production of fibers of industrial application used, in particular, in tire industry. SUBSTANCE: method involves treatment with plasma in gas medium of aramide monofil with diameter D = 40-480 mcm, textile number of 1.7-260 tex, strength T, cN/tex satisfying relation T ≥ 170-D/3, module of not less than 2000 cN/tex. Treatment is carried out at reduced or atmospheric pressure until wettability index of monofil corresponds to relation WW_SL ≥ 120, where WW_SL is reciprocal to work of adhesion of solid body with liquid expressed in MJ/sq.m².. Treated monofils are formed in rope. Contacting of these monofils or rope with rubber composition and subsequent vulcanization result in reinforced articles. Casings of pneumatic tires are also made from said monofils treated with plasma. EFFECT: higher efficiency. 12 cl, 4 tbl
