Elastic dope dyed yarn composite of two colors and process of manufacturing same

A process of manufacturing an elastic dope dyed yarn composite of two colors, comprising the steps of:

• conveying a spin drawn yarn to a second rotating spinning drums unit via a first rotating spinning drums unit;
• conveying a partial oriented yarn to the second rotating spinning drums unit to join the spin drawn yarn via a third rotating spinning drums unit, a heater, and a false twister;
• conveying an elastic yarn to the second rotating spinning drums unit to join the SDY and the partial oriented yarn via a fourth rotating spinning drums unit;
• conveying the joined spin drawn yarn, the partial oriented yarn, and the elastic yarn to an airjet;
• and
• activating the airjet to twist and integrate the joined spin drawn yarn, the partial oriented yarn, and the elastic yarn as an elastic dope dyed yarn composite having two colors.
