Multifunctional ultrasonic ion continuous zero-discharge dyeing machine and dyeing process thereof

Abstract

The invention relates to a multifunctional ultrasonic ion continuous zero-discharge dyeing machine which comprises an unreeling system, an etherealization treatment system, an ionic reaction type drying system, an ultrasonic dyeing system, an infrared constant-temperature econtrol system and a reeling system. The invention also relates to a dyeing process of the multifunctional ultrasonic ion continuous zero-discharge dyeing machine. The dyeing process sequentially comprises the following steps of unreeling, performing etherealization treatment, drying, dyeing, performing color-fixation reduction econtrol drying, and reeling. The multifunctional ultrasonic ion continuous zero-discharge dyeing machine has the beneficial effects that the dry and wet rubbing fastness after dyeing is high, fading is not caused by soaping and alkali steaming, the process is simple, less pollution is generated, mass production can be realized, and the multifunctional ultrasonic ion continuous zero-discharge dyeing machine can be used for preparing shuttling yarns and is wide in application range.

Description

Technical field [0001] The invention relates to a multifunctional ultrasonic ion continuous zero-discharge dyeing machine and its dyeing process. Background technique [0002] Sulfur dyes are commonly used and indispensable raw materials in our printing and dyeing industry. In the past, sulfur dyes have long troubled us in the dyeing process: 1. poor color fastness; 2. shading is not bright enough; 3. strong Decrease; 4. The chromatogram is incomplete and can not achieve fresh colors; 5. The washing water consumption is large, the pollution is serious, and the COD value in the sewage is extremely high. [0003] Conventional dyeing adopts vulcanization dyeing process. The process flow is: unwinding → caustic soda penetrant boiling → dyeing → oxidation → washing → neutralization oxidation → drying → (sizing) → winding. The yarn obtained by conventional dyeing fades seriously. The wet and dry rubbing fastness is 2 to 3 grades, and the washing fastness is 3 to 3.5 grades. [0004] Afte...
