METHOD OF ARAMID CORD TREATMENT Russian patent published in 2008 - IPC D01F11/08 D06M15/39 D06M15/693 D06M101/36 

FIELD: technological processes.

SUBSTANCE: invention is related to production technology of synthetic cord, in particular, to impregnation and thermal treatment of aramid cord, and may be used in tyre and rubber industry. Aramid cord of all brands is impregnated with latex-resorcin-formaldehyde or latex-resorcin-formaldehyde-soot compounds on the basis of latexes "ДБА"-1, "СКД"-1s and 5% solution of resin "СФ"-282, with concentration of 12-14%. Then cord is thermally treated to residual moisture of 0.5-1.0% at 120-140°C with load of 400-800 kg/cloth. Cord produced by this method is repeatedly impregnated and thermally treated according to the same modes.

EFFECT: simplified treatment of aramid cord; reduction of power inputs; improvement of its physical-mechanical properties and increase of operability of tyres and rubber items.
