Abstract: a kind of invention. Knitted fabric The process of bleaching and dyeing is divided into three stages: pretreatment, dyeing and after treatment. In the process of pretreatment, the billet is treated by cold pad batch treatment in the rolling mill and washed in the washing equipment. The liquid ratio of the billet is 100 to 110% and the heap is set at 4~12. The dyed blank is dyed into the dyeing machine, and then washed in the dyeing machine. The dyestuff includes the dyes, salts and fixative added in sequence. The post-processing means that the billet discharge machine is washed in the washing equipment and then is softened, and finally dehydrated is made into the undetermined cloth. The advantages are: dyeing machine is only used for dyeing, greatly improving the billet output rate, reducing energy consumption and quality control; segmented process reduces the quality of the pre-processing problem; the process is independent, ensuring the quality of the post process, fixing the color and softening outside the dyeing machine, reducing the dye cylinder washing, softening the dyed gray fabric, and softening it. Effect Superiority.

Sovereignty: a knitted fabric segmented style Bleaching and dyeing process After cold pad batch treatment in the rolling mill, the water is washed in the washing equipment. The cold rolling process is to store the billet after rolling. After the rolling, the liquid ratio of the billet is 100 to 110% and 4~12 hours. The dyeing section refers to the dyeing of the billet before dyeing into the dyeing machine with added dyeing ingredients, and then the washing process is carried out in the dyeing machine. The dyeing ingredients include the dyes, salts and fixative added in sequence. The post-processing means that the dyed billet discharge machine is washed in the washing machine and washed in the wash water, and then is softened and dehydrated to make the undetermined cloth. The bleaching and dyeing process is divided into three parts: pretreatment, dyeing and post-processing, and the dyeing and post-processing of the pre treated knitted fabric is characterized by that the pretreatment is the blank.
