In general the synthetic filament yarn has no twist or very low twist.
But after proceed next steps the yarn has become one direction
twist lets assume yarn was false twisted into S-direction.
yarn 1st. heater S I 2nd. heater Z
S : S-twist friction unit
I : intermingling nozzle
Z : Z-twist de-torque nozzle

The S-twist false twist yarn moves to second heater where torque force
is reduced by de-torque nozzle
The parameters that control the de-torque are :
* air pressure
* over feed % through second heater.
* heater temperature
* yarn speed |
