Turbulent current type cheese dyeing method and apparatus thereof

Abstract

The invention belongs to the technical field of dyeing textile material, and relates to a turbulence type cheese dyeing method. The cheese is dipped in dye vat, in which dye liquor cyclically flows, for dyeing, and the dye liquor cyclically flows in the amplitude changed turbulence mode in the dye vat. A turbulence type cheese dyeing device comprises a dye vat accommodating the dye liquor, the dye vat is provided with a main pump driving the dye liquor to cyclically flow, and the main pump drives the dye liquor to flow cyclically in the amplitude changed turbulence mode in the dye vat. The dye liquor cyclically flows in the amplitude changed turbulence mode, thereby maximally making the dye liquor evenly pass through the cheese without a dead angle, and avoiding the occurrence of impermeable dyeing and inside-and-outside difference. As a method of making even dye only by increasing pump speed is saved, the aim of energy conservation is achieved. Because a motor of the main pump operates with changed rotation speed, the power is saved by 30 to 50%. Moreover, the problems of low strength and excessive hairy feather due to impact of liquid flow on yarn are solved, and the strength of the original fabric is maintained.

Description

technical field [0001] The invention belongs to the technical field of textile material dyeing, and in particular relates to a turbulent cheese dyeing method for cheese dyeing, and also relates to a turbulent cheese dyeing device. Background technique [0002] At present, common dyeing methods such as figure 1 As shown, the yarn is first wound layer by layer onto the dyeing tube for dyeing to form a cheese 7, then a plurality of cheeses 7 are mounted on the cheese bracket 6, and then the cheese loaded with the cheese 7 The yarn bracket 6 is erected and hung into the dye vat 1 containing the dye solution. Finally, seal the dye vat 1, drive the main pump 2 to rotate, so that the dye liquor flows in the dye vat under high temperature and high pressure conditions, and the dye liquor will circulate outward from the middle of the cheese, and the cheese 7 will pass through the dye vat for a certain period of time. stained by soaking. The main pump of the above-mentioned dyeing m...

AI Technical Summary

Problems solved by technology

The main pump of the above-mentioned dyeing method is to keep the dyeing liquid circulating and dyeing at a constant speed, so that the liquid flow direction of the dyeing liquid flowing through the cheese 7 is as follows: figure 2 As shown by the arrow in the middle, the liquid flow is laminar flow, and the direction of the dye liquid flow does not change, which is easy to cause different liquid flows at different cheese positions, and what is more serious is that some liquid flows rarely reach "Dead corners", resulting in some positions being impermeable and internal and external differences

In order to make the dyeing uniform, the m
