Abstract

The present invention provides a production process characterized in that a false twisting process is added between a spinning process and a winding process so that yarn slivers undergo excessive pre-torsion in an axial direction and twists which are same in quantity but different in twisting direction are generated on the yarn slivers. Absorption of glucose-containing sulfur dyestuff is performed in a dyeing process. An ammonia removal process is performed in a high-temperature and high-pressure tank so that residual ammonia in a fabric is evaporated. The evaporated ammonia is collected and then fed back to a mercerizing process for continuous use. The present invention also provides a production line including a spinning unit having a false twisting device, a dyeing unit configured to realize the dyeing process, and a liquid ammonia finishing unit consisting of a fabric mercerizing device, an ammonia removal device, an ammonia recycling device and a controller.
