Cone yarn dyeing system

Abstract

The invention relates to a cone yarn dyeing system which is characterized by comprising a high-pressure circular dip dyeing mechanism and a normal-pressure brush dyeing mechanism, wherein the high-pressure circular dip dyeing mechanism is connected in series with the normal-pressure brush dyeing mechanism; the high-pressure circular dip dyeing mechanism performs dip dyeing on cone yarns to achieve primary dyeing; and the cone yarns after the dip dyeing are subjected to brush dyeing by the normal-pressure brush dyeing mechanism to achieve secondary dyeing. According to the system, the traditional single vat dyeing is now changed into double vat yarn dyeing; with the adoption of a bidirectional circulation pump, the front and back dyeing of the yarns in two vats can be achieved; technical requirements are met; a dyeing effect is guaranteed; compared with the traditional dyeing machine, the dyeing system only requires half of a dyeing solution to dye the same quantity of the yarns; the consumption of the dyeing solution is greatly reduced; at the same time, the consumption of heating steam can also be reduced with the reduction of the consumption of the dyeing solution; and the production cost is greatly lowered.

Description

technical field [0001] The invention relates to the field of package yarn dyeing, in particular to a package yarn dyeing system. Background technique [0002] Traditional dyeing methods mostly use water as the carrier of the dye to dye the object to be dyed under normal pressure. However, on the one hand, the dyeing process not only needs to consume a large amount of water resources, but also a large amount of waste water seriously pollutes the environment and is difficult to recycle, which seriously restricts economic development. On the other hand, since the dyeing is carried out under normal pressure, it takes a long time for the gas adsorbed on the object to be dyed to be discharged after the dyeing solution is input and the dyeing starts. The air in the air often hinders the infiltration of the dye solution, so the dyeing time of the dyed object is long, the energy consumption is relatively large, the dyeing is uneven and prone to color difference. [0003] In the dye...
