METHOD OF MAKING CORD AND CORD Russian patent published in 2012 - IPC D02G3/00 

FIELD: textile, paper.

SUBSTANCE: method involves preparation of aramid fibers and subsequent braid of core. Preparation of fibers for weaving is accomplished by cabling and winding on the supply packages installed on the cord-braiding machine. For braiding, aramid fibers single or cabled in 2÷10 threads of linear density from 9.0 to 600 tex are used. As a core, single aramid fibers of linear density from 9.0 to 3600 tex are used, and carbon fibers single or cabled in two or more threads of linear density from 100 to 3700 tex. The number of weaving is set from 1.0 to 12.0 per 1 cm. The number of fibers for braiding is taken from 3 to 64 to obtain a cord of minimum diameter 1.0 mm.

EFFECT: invention enables to increase the strength of the resulting cord while simultaneous simplifying the technology of its manufacturing.
