Cone yarn anhydrous dyeing equipment and method and product

Abstract

The invention provides cone yarn anhydrous dyeing equipment and method and a product. The cone yarn anhydrous dyeing equipment comprises a dye kettle, a dyeing kettle, a recycling kettle and a dyeing circulating system communicated with the dye kettle, the dyeing kettle and the recycling kettle. The cone yarn anhydrous dyeing equipment is characterized in that a cone yarn inlet is formed in the top of the dyeing kettle, a sealing cover is arranged on the cone yarn inlet, a yarn center shaft is vertically arranged in the middle in the dyeing kettle, and the yarn center shaft is an air outlet pipe with fluid release holes formed in the pipe wall; an air inlet pipe is arranged at the bottom of the dyeing kettle and communicated with the air outlet pipe, and a dyeing kettle outlet is formed in the dyeing kettle; the dyeing circulating system comprises a CO2 gas storage cylinder, a booster pump, a circulating pump and a pipeline. Various dyes are placed in the dye kettle, cone yarn is placed in the dyeing kettle, CO2 is introduced into the dye kettle, the dyes are gradually dissolved and reach the dyeing kettle along with CO2 fluid, and the coloring and dispersing processes are started. The advantages of being high in production efficiency, good in level dyeing effect, high in safety and suitable for anhydrous dyeing of the dacron cone yarn are achieved.

Description

technical field [0001] The invention belongs to the technical field of dyeing and relates to a supercritical CO 2 Anhydrous dyeing technology, specifically a kind of anhydrous dyeing equipment, dyeing method and products for bobbins. Background technique [0002] my country is a country with a serious shortage of water resources, and the environment of water resources is also deteriorating. Coupled with the waste of water, the situation of water resources is not optimistic. In the traditional dyeing process, we usually use water as the main medium. A large number of chemical substances such as dyes and surfactants will have a negative impact on the sustainable development of the environment. In addition, neutralization, sedimentation and other treatments are required for the sewage discharged from dyeing, which requires a lot of manpower and material resources. According to incomplete statistics, the annual water consumption of my country's textile printing and dyeing ind...

Problems solved by technology

However, in the small and medium-sized equipment disclosed above, its process technology is not mature

Moreover, in the patent literature that can be retrieved at present, it has not been found that there is a polyester cheese dyeing technology disclosure with mature technology.

The dyeing of the cheese is that the yarn is wound on a metal or disposable plastic tube, and it needs to rely on the force of the circulating pump to penetrate the yarn from the inner layer to the outer layer, but because the fabric yarn on the warp beam is at rest state, only relying on the forced circulation of the fluid to drive the dye through the yarn, so it is easily affected by factors such as the mass transfer path of the fluid, resulting in a decrease in level dyeing

In addition, due to the high density of the cheese, it also increases the design requirements and difficulty of the circulation pump, which also puts forward more stringent requirements on the key components of the dyeing system
