Example Embodiment

[0022] Example 1

[0023] A one-way cyclic dyeing process of cheese yarn, which drives the dye liquor to circulate unidirectionally from the inside of the cheese yarn to the outside through the change of the rotation speed of the main pump in the dyeing vat.

Example Embodiment

[0024] Example 2

[0025] A one-way cyclic dyeing process of cheese yarn, which drives the dye liquor to circulate unidirectionally from the inside of the cheese yarn to the outside through the change of the rotation speed of the main pump in the dyeing vat.

[0026] After the main pump runs at 70% full speed for 20 seconds, the speed is reduced by 20%, and after 20 seconds, it returns to 70% full speed alternate operation.

Example Embodiment

[0027] Example 3

[0028] A one-way cyclic dyeing process of cheese yarn, which drives the dye liquor to circulate unidirectionally from the inside of the cheese yarn to the outside through the change of the rotation speed of the main pump in the dyeing vat.

[0029] After the main pump runs at 95% full speed for 20 seconds, the speed is reduced by 20%, and after 20 seconds, it returns to 95% full speed alternate operation.

[0030] The liquor ratio of the dyeing is 1:3.

Abstract

The invention provides an unidirectional circulation dyeing process for cheese. The unidirectional circulation dyeing process for the cheese is characterized in that a single circulation mode is adopted by dyeing liquor, and the dyeing liquor is driven to circulate from the interior of the cheese to the exterior of the cheese through the changing of the rotating speed of a main pump in a dyeing vat. According to the unidirectional circulation dyeing process for the cheese, a dyeing pulse technique and a spray technique are adopted to change a circulation mode of the dyeing process as single outflow dyeing, only half or even lower water level of raw materials are soaked by the dyeing liquor, dyeing can be carried out, the bath ratio can be lowered to 1:3, and production water consumption can be reduced greatly.

Description

technical field [0001] The invention belongs to the technical field of dyeing of textile materials, and in particular relates to a unidirectional circular dyeing process of cheese. Background technique [0002] From the inner layer to the outer layer of the dyeing bobbin, the radius gradually increases, and the yarn capacity of each layer increases accordingly, but the effective flow rate of the main pump does not increase on each layer. That is to say, the flow rate of the dye liquor passing through the yarn layers at different radii is the same. When the dye liquor circulates positively from the inside to the outside, the area of ​​the yarn along the course increases gradually, and the dye liquor passing through the unit area increases with the increase of the radius. Increase and decrease, due to less dye and more yarn, the problem of deep inside and shallow outside will occur. [0003] When the dye liquor is in reverse circulation (from outside to inside), the linear de...
