Description

High-efficiency double impregnation mechanism of continuous expansion CPB dyeing/bleaching feather

The present invention relates to the technical field of continuous expansion CPB (cold-pad-batch) dyeing/bleaching equipment, and in particular, to a structural improvement aspect of a trough dyeing operation method and a folder dyeing operation method. .

In the continuous expansion CPB (cold-pad-batch) dyeing/bleaching facility, the fabric is usually impregnated by a trough dyeing operation method or a folder dyeing operation method, and then again with a uniform press-fitting roller. The treatment liquid is immersed. In the expansion CPB dyeing/bleaching facility, in addition to the linear pressure and average degree of immersing the treatment liquid with a uniform press-fitting roller, the impregnation effect before immersing the treatment liquid with a uniform press-fitting roller is also very important; In a uniform press-fit roller of the same linear pressure, if the fabric impregnation is not sufficient, several problems arise; When dyeing, if the amount of impregnation of the fabric left-middle-right is not sufficient, deviations easily occur in immersing the treatment liquid with a uniform press-fit roller, resulting in a left-middle-right color difference or dyeing stain; If the fabric impregnation is not sufficient during CPB bleaching, deviations easily occur in the immersion formed by uniformly press-fitting with a roller, and the left-middle-right capillary effect is not consistent; If the amount of impregnation between the front and rear sections of the fabric is unstable during dyeing, there is an easy deviation in the immersion formed by uniformly press-fitting with a roller, resulting in color differences at the front and rear ends of the fabric roll; During CPB bleaching, if the fabric impregnation is unstable, deviations easily occur in the immersion formed by uniformly press-fitting with a roller, resulting in inconsistent capillary effects at the front and rear ends of the fabric roll. Therefore, the quality of the expanded CPB dyeing/bleaching of the fabric is mainly determined by the impregnation effect before forming the immersion by uniformly press-fitting with a roller.

In a normal situation, when the gilling fabric is expanded CPB dyeing/bleached, since the structure of the gilling fabric is relatively dense, the gilling operation method is used; When the guiling fabric passes through one or more guide rollers inside the immersion trough, the fabric is allowed to absorb the work fluid inside the immersion trough for a relatively long period of time, and the fabric is immersed while passing through the uniform press-in roller from bottom to top, Drain the fabric and wrap it with a roll. However, the disadvantage is, the more guide rollers there are, the greater the running tension becomes. At the same time, some of the guide roller quantity also directly affects the capacity of the work fluid inside the immersion trough, and if the capacity of the factory fluid inside the immersion trough is too large, the circulation time of the work fluid directly increases and affects the work solution stability, and it is easy to follow. There is a color difference at the stage.

Since there is a disadvantage of increasing the tension when using the dip dyeing method, in a normal situation, when performing expansion CPB dyeing/bleaching, the structure of the knitted fabric relatively easily affects the quality by changing the tension, so most of the folder dyeing operation methods And use; The knitted fabric is first passed through an opentop plate from top to bottom, the curled edges are unfolded according to the traditional method of the knitted fabric, and then impregnated in a V-shaped clamping trough; V-type clamping trough is formed by press-fitting two uniform press-fit rollers and then sealing the V-shaped space formed at the top on both sides.The inside of the V-type clamping trough has very little work fluid capacity, and the V-type clamping trough for knitted fabrics After being impregnated by passing through, it is directly wound into a roll through a uniform press-fitting roller. However, the disadvantage is that the time for the fabric to contact the working fluid is very short, so in the current knitted fabric with a large number of yarn counts, it is not possible to immerse the treatment liquid through a uniform press-fitting roller while the fabric is sufficiently impregnated with sufficient time. Therefore, color differences and staining problems easily appear.

When all Guilling fabrics are dyed/bleached for expansion CPB, the same mode of impregnation operation is used; In addition, 1) under conditions where the tension is controllable; 2) under sufficient impregnation effect; 3) In the condition that the working fluid volume is low; the most desirable technical solution can be constructed if the most sufficiently impregnated under the same three conditions.

Overall, the present invention was created to sufficiently ensure the impregnation effect under conditions in which the tension is controllable, and to solve the technical problem in which the treatment liquid immersion is uneven due to insufficient impregnation of the fabric in the dyeing trough. Expression expansion CPB (cold-pad-batch) dye / bleach to provide a high-efficiency dual impregnation mechanism of the padder (padder).
