Abstract

The invention provides a production technological process of environment-friendly jean. The production technological process of the environment-friendly jean is characterized in that a false twisting process is added between a spinning process and a spooling process, slivers are excessively pre-twisted in the axial direction, and twisting turns of the same numbers but in different twisting directions are formed on the silvers; in a dyeing process, sulfur dye containing glucose is adsorbed; an ammonia removal process is conducted in a high-temperature high-pressure tank, so that remaining ammonia in fabric is evaporated, and the evaporated ammonia is collected and delivered back to a mercerizing process so as to be continuously used. The invention further provides a production line of the environment-friendly jean. The production line comprises a spinning unit with a false twisting device, a dyeing unit for conducting the dyeing process and a liquid ammonia finishing unit composed of a fabric mercerizing device, an ammonia removal device, an ammonia recovery circulating device and a controller. The use amount of electricity, water and chemical articles can be saved, production efficiency is improved, labor resources are saved, and the discharging amount of sewage and pollutants is reduced.
