Cloth dyeing method for discontinuous patterns

Abstract

The invention discloses a cloth dyeing method for discontinuous patterns. The cloth dyeing method comprises the steps that dye liquor is sprayed to a to-be-dyed cloth in the rotating process in a cloth dyeing machine, after dye is sprayed to the whole length of the to-be-dyed cloth at least once by a dye liquor nozzle of the cloth dyeing machine, one part of the to-be-dyed cloth forms a wavy intermediate product in the cloth dyeing machine, and then the liquor level of the dye liquor in the cloth dyeing machine is gradually increased; then, the pressure in the cloth dyeing machine is changed by utilizing short-time rapid heating, so that one part of the intermediate product is gradually floated to be above the liquid level of the dyeing liquid, the other part of the intermediate product issoaked in the dyeing liquid, then, the temperature in the dyeing machine is maintained at the heating temperature for a period of time to finish color development, and dyed cloth with discontinuous patterns is generated.

Description

technical field [0001] The invention relates to a method of dyeing cloth, in particular to a method of dyeing cloth which can provide discontinuous patterns. Background technique [0002] In the field of fabric dyeing, the dyeing method used for man-made fibers, such as polyamide (PA), usually involves the step of adding acid to change the pH value of the dye solution, and further make the man-made fibers bond with acid dye molecules In addition, it also usually involves different processes such as heating, color development, water washing and color fixing. [0003] At present, it is widely used in the dyeing method of rope dyeing machine. The color of the finished product is mostly single and the pattern is fixed, and the product variability is low; if the product needs to have irregular or discontinuous patterns, you need to use it. Ink-jet printing machine; however, the conventional ink-jet printing machine needs multiple workstations in the production process of a produ...

Problems solved by technology

[0003] At present, it is widely used in the dyeing method of rope dyeing machine. The color of the finished product is mostly single and the pattern is fixed, and the product variability is low; if the product needs to have irregular or discontinuous patterns, you need to use it. Ink-jet printing machine; however, the conventional ink-jet printing machine needs multiple workstations in the production process of a product, which consumes a lot of manpower and man-hours, and although discontinuous patterns can be artificially designed, usually The finished product of inkjet printing is within a certain length, and the pattern will still be repetitive

Therefore, the usual method of dyeing cloth is missing
