METHOD OF PRODUCTION OF TWIST THREAD Russian patent published in 1998 - IPC

FIELD: methods of production of twist thread on ring-spinning machine. SUBSTANCE: the offered method for production of twist thread on ring-spinning machine provides for passing of two separate flows of semifinished product through drawing mechanism and upon passing, formed components are joined together, and imparted twisting to twist thread is extended to the components to lend them twist of same direction and value. Supplied to each separated flow of semifinished product passed through drawing mechanism are core threads, and upon leaving the drawing mechanism, prior to joining together, reinforced components are formed by web winding on core threads. Web fibers prior to their winding on threads are treated with compounds to reduce friction and to increase conductivity. Core threads are preliminarily twisted with twist opposite in direction to that imparted to twist thread and with value less than that of twist thread by a factor of 1.3-1.5. EFFECT: higher efficiency. 2 cl, 3 tbl
