Description

Technical Field

[0001] The utility model relates to the field of textile equipment, in particular to an automatic distribution system for pre-treatment additives. Background Art

In the prior art, many printing and dyeing factories still manually configure the solution of a preset proportion, or uniformly distribute it through a liquid distribution center. However, if it is used independently, or the factory has only one production line, these two methods of liquid distribution will cause a certain degree of solution waste, and workers are very likely to make mistakes when manually configuring these solutions, thus affecting the effect of cloth pre-treatment.
