Problems solved by technology

[0004] Although the double-cylinder dyeing machine disclosed in this patent can make the dyeing effect better, one end of the yarn hanging frame of the double-cylinder dyeing machine is a suspended end, and the carrying capacity is poor; without a pedal device, the operator cannot conveniently move the upper yarn The thread is taken off, and the operation is laborious; there is no preparation method for the dye solution, so a dyeing method that can more effectively dye the cotton yarn for weaving denim fabrics is designed

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 ...
