Problems solved by technology

However, because the jet hank yarn dyeing rotates with the cantilever during the dyeing process, and there is relative friction between the hank yarn and the cantilever, which makes the wool knitting yarn hairy and felted, the jet hank yarn dyeing cannot completely replace the hank cabinet.

Embodiment 1

[0010] Such as figure 1 As shown, the soaking and alternating skein dyeing method described in this embodiment is to put a part of the skeins into the dye solution for dip dyeing, and the other part of the skeins to carry out leaching dyeing by pouring the dye solution. The leaching and Dip dyeing is carried out alternately. Said drip dyeing is a dyeing method in which the dye solution is poured on the skein yarn at intervals, and the dye solution flows down the skein yarn under the action of gravity. This dipping and alternating skein dyeing method uses a dye solution with a dyeing bath ratio of 1:14. The dye is a level-dyeing weak acid dye. The dyeing start temperature is 45°C, and the temperature is raised to 95°C at a rate of 1°C per minute. Finally, keep the temperature for 60 minutes, and the interval between forward and reverse conversion of the water pump is two minutes, so as to ensure that the dye liquor that plays the role of exhaust dyeing is alternately flowing i...

Embodiment 2

[0017] Such as figure 1 As shown, the immersion dyeing cabinet described in this embodiment is mainly composed of a cabinet body 1, a dye solution chamber 7 is provided on the upper part of the cabinet body 1 through an orifice plate 6, and a dye solution pool 4 is provided on the lower part of the cabinet body 1. A water pump 3 is provided in the dye liquor pool 4, and the water pump 3 is an axial flow pump, which is connected with a power unit through a transmission shaft 10 to provide power for the internal dye liquor circulation. The middle space of cabinet body 1 is divided into the cabinet interior space 5 of both sides by dividing plate 2, is provided with yarn bar 9 in cabinet interior space 5. When in use, the skein 8 is fixed on the yarn rod 9, and the rotation direction of the axial flow pump is intermittently and alternately reversed, so that the skein can be soaked and alternately dyed.

Abstract

The invention discloses a dip and spray alternate hank dyeing method, which is to perform dip dyeing and spray dying on hank yarns alternately regularly, and comprises that: one part of the hank yarns are placed into dye solution for dip dyeing and the other part of the hank yarns are sprayed with the dye solution for spray dyeing; and then the two parts of the hank yarns are subjected to the dipdyeing and spray dyeing alternately and interchangeably at intervals, and the step is repeated until the dyeing is completed. The dip dyeing and spray dyeing alternate method can effectively reduce the minimum dyeing bath ratio. The designed dip and spray alternate hank dyeing method effectively reduces the minimum dyeing bath ratio to less than 1:14, can reduce water quantity by 30 percent and vapor quantity by about 25 percent compared with the prior dip dyeing method, and can effectively achieve the aims of saving energy and water and reducing the discharge amount of sewage and carbon dioxide. Through the dyeing method, the dyed hank yarns have even color and meet the requirement of weaving sweaters, and the color fastness can meet the pure wool standard of International Wool Secretariat IWS through detection.

Description

technical field [0001] The invention relates to the field of textile printing and dyeing, especially the field of dyeing of hank yarns. Background technique [0002] The current skein dyeing generally adopts two kinds of sub-cabinet dip dyeing and jet dyeing. The characteristic of the skein cabinet type dip dyeing is that the skein is always soaked in the dye solution during the dyeing process, the skein is suspended on the upper and lower yarn rods, and the dye solution flows alternately in forward and reverse directions. The flow of the dye solution is continuous, but The minimum dyeing bath ratio of this method (the mass ratio of the dyed object and the skein to the dye liquor) is 1:20, which is relatively high compared to the jet skein dyeing, resulting in the water consumption and consumption of this dyeing method. The steam volume is relatively high. Jet-type skein dyeing is to put the skein on the cantilever with nozzle holes, and the dye solution is sprayed onto th...
