Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a dyeing method, in particular to a cotton yarn dyeing method for weaving denim fabrics. Background technique [0002] Denim is an enduring traditional clothing fabric. The traditional production method of denim fabric is to indigo-dye the primary color yarn used for the warp direction, and then make the warp yarn after dyeing into a weaving beam, and then weave the cloth. Denim fabric is a yarn-dyed fabric that is dyed first and then woven. The warp yarns are oxidized and dyed indigo, while the weft yarns are not oxidized and dyed. The above are the commonly used production processes and conventional denim in denim manufacturers at home and abroad. At the same time, the existing dye vats for dyeing denim have a single structure and a single dyeing and processing operation mode, which leads to problems such as low dyeing efficiency, poor printing and dyeing uniformity, low dye ...
