Abstract
The invention discloses a supercritical carbon dioxide nutbutton dyeing kettle and a dyeing technology thereof. The dyeing kettle comprises a kettle body, and the bottom of the kettle body is provided with a carbon dioxide fluid and dye inlet and a carbon dioxide fluid and dye outlet. When dyeing is performed, carbon dioxide fluid and dye at the bottom flow into the kettle body to impact on buttons and drive the buttons to be dyed in a non-static mode, therefore, the buttons can move under the variable speed impact of air flow, and the dyeing defects at the overlapping positions of the buttons are avoided. Meanwhile, the bottom of a barrel body of the dyeing kettle is designed to be of an inverted-trapezoidal structure, and therefore the problem that the buttons cannot be dyed due to the fact that the buttons cannot make contact with the carbon dioxide fluid carrying the dye is solved. By adopting the dyeing technology, the buttons which are rich and complete in color can be obtained, the dyed products do not need aftertreatment such as cleaning and drying, waterless dyeing is achieved in the overall process, the production cost is saved, the dyeing quality is improved, and the environmental pollution is reduced.
Description
Technical field
The present invention's is related to technical field of textile printing, more particularly to supercritical carbon dioxide fruit button dyeing caldron and its
Non-aqueous dyeing technique.
Background technology
China is the country of a shortage of water resources, and water resource environment is also constantly deteriorating, along with the waste with water, water
Resource situation is even more and allows of no optimist.The traditional water bath dyeing of button, mainly with water as medium, in dyeing course, substantial amounts of dye
The chemical substance such as material, auxiliary agent and surfactant causes severe contamination to environment, resistant to elevated temperatures colouring agent kind is few, colour system not
Entirely, adding Masterbatch causes button production process unstable, governs the sustainable development of garment accessories industry.2l centuries are to easy
The requirement of controlling, high efficiency, nonstaining property and reusable edible is increasingly projected.It is developed in the overcritical of last century Mo
Carbon dioxide waterless staining technique is considered as a kind of " green, can holding because of outstanding features such as its is pollution-free, short route, high efficiency

Using the structure it is easy to disassemble and washing, improve staining efficiency.
Used as preferred technical scheme, the upper end of the cylinder is provided with lid with holes.Using the structure, it is easy to dress to take knob
Button can be directly loadable into by the hole of lid with holes, after dyeing terminates in the case where lid is not opened when button, i.e. practical application
Button can also be directly taken out by the hole of lid with holes in the case where lid is not opened.On the other hand, the lid with holes
Can moderate control CO 2 fluid and dyestuff the rate of outflow.
Used as preferred technical scheme, the lid with holes is provided with draw ring, convenient to pull out cylinder.
Above-mentioned supercritical carbon dioxide fruit button dyeing caldron, in dyeing course, carries the overcritical dioxy of dyestuff
Change carbon by the carbon dioxide and dyestuff entrance of kettle, the chassis with holes of cylinder body bottom, curved surface netware are flowed through successively and enters cylinder, shape
Button dyeing is carried out into eddy airstream.The carbon dioxide for carrying some dyes flows out from carbon dioxide outlet, forms circulation, dyeing
Button circulating with supercritical carbon dioxide in kettle, gradually completes dyeing.
Used as preferred technical scheme, the sealing kettle cover is flexibly connected by opening clip soon with the kettle.
Used as preferred technical scheme, the periphery of the kettle is provided with heating jacket, to heat and be incubated, the heating
The bottom of chuck is provided with thermal medium entrance, and top is provided with thermal medium outlet.
Used as preferred technical scheme, the cylinder is provided with cylinder twist portion, the kettle and is provided with kettle twist portion, described
Cylinder is connected by cylinder twist portion with kettle with kettle twist portion.
The supercritical carbon dioxide of carrying dyestuff carries out the molecular dynamics mechanism of button dyeing in cylinder：It is dissolved in
Dyestuff in supercritical carbon dioxide fluid moves closer to material interface into Dynamic Boundary layer, when dyestuff is near material interface
Afterwards, by the close material of diffusion of itself, when molecular force is sufficiently large, dyestuff is adsorbed by material, and dyestuff is formed inside and outside material
Concentration difference, completes the absorption set of dyestuff, so as to realize the non-aqueous dyeing of supercritical carbon dioxide fluid.
Another object of the present invention is to provide carries out fruit button using above-mentioned supercritical carbon dioxide fruit button dyeing caldron
