Problems solved by technology

However, because carbon dioxide is a non-polar substance, it can only dissolve small molecules and low-polarity dyes, and then carry them to the dyeing and finishing tank to complete the dyeing of textile fiber materials; for most dyes except disperse dyes, it is difficult to dissolve In supercritical carbon dioxide fluid

Embodiment 1

[0041] Place 1000g of Disperse Blue 60 in the sample chamber of the material unit in the dye finishing agent kettle. During the dyeing and finishing process, under the conditions of 120°C and 24MPa, supercritical carbon dioxide fluid enters the material unit 12 from the fluid inlet 101 and passes through the fluid distributor 102 After uniform distribution, it diffuses from the outside into the sample chamber composed of aggregation distributor I 103 and aggregation distributor II 104, blowing and dissolving the dye located therein. Carry the carbon dioxide that dyestuff enters fluid channel 105 through the hole that distributes on fluid channel 105 subsequently, flow through the fluid outlet 106 of material unit 12 and the carbon dioxide fluid outlet 11 of dye finishing agent kettle and enter into the dyeing and finishing tank that textiles is contained, realize its Dyeing of inner textiles. At the same time, the carbon dioxide fluid in the dyeing and finishing kettle flows o...

Embodiment 2

[0044] Place 500g of Disperse Red 60 in the sample chamber of the material unit in the dye finishing agent tank. During the dyeing and finishing process, under the conditions of 120°C and 30MPa, the supercritical carbon dioxide fluid enters the material unit 12 from the fluid inlet 101 and passes through the fluid distributor 102 After uniform distribution, it diffuses from the outside into the sample chamber composed of aggregation distributor I 103 and aggregation distributor II 104, blowing and dissolving the dye located therein. Carry the carbon dioxide that dyestuff enters fluid channel 105 through the hole that distributes on fluid channel 105 subsequently, flow through the fluid outlet 106 of material unit 12 and the carbon dioxide fluid outlet 11 of dye finishing agent kettle and enter into the dyeing and finishing tank that textiles is contained, realize its Dyeing of inner textiles. At the same time, the carbon dioxide fluid in the dyeing and finishing kettle flows o...

Embodiment 3

[0047] Place 100g of Disperse Yellow 119 in the sample chamber of the material unit in the dye finishing agent tank. During the dyeing and finishing process, under the conditions of 80°C and 15MPa, the supercritical carbon dioxide fluid enters the material unit 12 from the fluid inlet 101 and passes through the fluid distributor 102 After uniform distribution, it diffuses from the outside into the sample chamber composed of aggregation distributor I 103 and aggregation distributor II 104, blowing and dissolving the dye located therein. Carry the carbon dioxide that dyestuff enters fluid channel 105 through the hole that distributes on fluid channel 105 subsequently, flow through the fluid outlet 106 of material unit 12 and the carbon dioxide fluid outlet 11 of dye finishing agent kettle and enter into the dyeing and finishing tank that textiles is contained, realize its Dyeing of inner textiles.

Abstract

The invention relates to a dye finishing agent kettle in supercritical carbon dioxide anhydrous dyeing and finishing equipment. The dye finishing agent kettle comprises a material unit which is of a column structure, and an aggregation distributor I and an aggregation distributor II are arranged in the material unit; the aggregation distributor I is located on the lower portion of a column and is of a funnel structure, and a large-end opening faces upwards; the aggregation distributor II is located on the upper portion of the column and is of a funnel structure, and a large-end opening faces downwards; a space forced by the aggregation distributor I, the aggregation distributor II and a column shell serves as a sample room; a fluid channel is formed between the aggregation distributor I and the aggregation distributor II, the upper end of the fluid channel is connected with a fluid outlet, and the lower end of the fluid channel is connected with a fluid distributor. According to the dye finishing agent kettle, not only can the solubility of dye be improved, but also the insoluble dye can be carried in a physical dispersion mode to enter the interior of the dyeing and finishing kettle, and therefore the dissolution and delivery problems of polar dye such as direct dye and activated dye in supercritical carbon dioxide are solved.

Description

technical field [0001] The invention relates to a dye finishing agent kettle in supercritical carbon dioxide anhydrous dyeing and finishing equipment, in particular to a dye finishing agent kettle in supercritical carbon dioxide fluid anhydrous dyeing and finishing equipment used in textile and dyeing and finishing industries. Background technique [0002] In recent years, supercritical fluid technology has been significantly improved and expanded from basic theoretical research to practical application, and has penetrated into supercritical fluid dyeing, supercritical fluid extraction, supercritical fluid chemical reaction, supercritical fluid cleaning technology and many other field. Carbon dioxide, the main greenhouse gas, is the most commonly used supercritical fluid. Its critical temperature and critical pressure are relatively mild, 31.1 °C and 7.38 MPa respectively, and carbon dioxide is non-toxic, molecular polarity is weak, and it has a four-order moment structure....
