Description
Technical Field
The present application relates to the field of dyeing machines, and more particularly to a method and system for low bath ratio fast level dyeing.
Background
Levelling, dyeing efficiency and bath ratio are three important factors in consideration of the performance of the dyeing machine. The bath ratio refers to the weight ratio between the fabric and the dye liquor during dyeing. The bath ratio is divided into large and small, and it is common in the industry to refer to a small bath ratio of 1:10 or less and a low bath ratio of 1:7 or less. The bath ratio is directly related to the water consumption in the dyeing process, so that the wastewater discharge after dyeing is directly related, and the development of the low bath ratio dyeing technology has very important significance for energy conservation, emission reduction and green production in the field of textile printing and dyeing.
However, the use of low bath ratios has a negative effect on levelling. On one hand, after the bath ratio is reduced, the dye uptake is increased quickly, slow dyeing cannot be achieved, uniform dyeing is difficult to achieve, on the other hand, the free water amount is reduced, the fabric cannot be fully soaked in the dye liquor, the incidence rate of re-dyeing after dye desorption is low, namely transfer dyeing cannot be achieved, and therefore the level dyeing property is reduced. The leveling property of the fabric is reduced along with the reduction of the bath ratio, and particularly after the bath ratio is less than 1:4, the leveling property is remarkably reduced.
Meanwhile, the dyeing efficiency directly affects the production efficiency and the enterprise profit. The active search for methods with low bath ratio, high levelling property and high dyeing efficiency remains a problem for continued research in the art.
Disclosure of Invention
To improve levelling and dyeing efficiency at low bath ratios, the present application provides a method and system for low bath ratio fast levelling.
In a first aspect, the application provides a method for low bath ratio fast level dyeing, which adopts the following technical scheme:
a method for low bath ratio quick level dyeing adjusts a longitudinal circulation system of a dyeing machine:
the longitudinal circulating system comprises a longitudinal circulating driving piece which is connected between the bottom of the dye vat and a nozzle of the spraying device and is used for driving the circulation of the dye liquor, and a longitudinal circulating pipeline which is connected with the bottom of the dye vat, the longitudinal circulating driving piece and the nozzle;
arranging a longitudinal circulating pipeline between the longitudinal circulating driving member and the bottom of the dye vat into a form of containing a plurality of longitudinal circulating return pipes; the connecting part of the longitudinal circulation backflow pipe and the dye vat is a longitudinal circulation backflow connecting port, so that the longitudinal circulation backflow connecting ports are distributed at the bottom of the dye vat at intervals.
Practice proves that the method can effectively improve the leveling property, improve the dyeing efficiency and reduce the bath ratio, and is analyzed as follows.
The following is an analysis made by the inventors of the present application of the principle of the above-described method of the present application in improving leveling property:
the mechanism of dyeing the fabric by the dye in the dye solution is that after the dye solution is contacted with the fabric, the dye in the dye solution is close to a fabric fiber dynamic boundary layer, the dye breaks through the boundary layer and diffuses to the surface of the fiber to further diffuse into the fiber and combine with the fiber, and meanwhile, part of the dye is attached to the fabric to be separated from the dye solution, so that the concentration of the dye solution is reduced.
In conventional dyeing machines, the fabric is completely immersed in the dyeing liquor, known as dip-exchange dyeing, which is a dyeing form with a large bath ratio. The low bath ratio dyeing machine adopts a cloth-liquid separation mode, the adopted dye liquor is less, and the fabric is continuously contacted with the dye liquor sprayed by a nozzle in the circulating operation process, so that the fabric is colored.
When the circulating system and the dye vat only have one longitudinal circulating reflux connecting port, the dye liquor is extracted from the dye vat close to the longitudinal circulating reflux connecting port by each circulation of the circulating pump, and the part of the dye liquor is conveyed to the nozzle for next contact exchange dyeing with the fabric, and the dye liquor of the dye vat far away from the longitudinal circulating reflux connecting port can reach the longitudinal circulating reflux connecting port and be extracted after flowing through a long path. Because every contact exchange dyeing all can make the dye liquor concentration appear the decline phenomenon, along with the continuous going on of dyeing process, compare with whole dye liquor in the dye vat, the number of cycles that the dye liquor that is close to the longitudinal circulation backward flow connector of dye vat participates in is many, the concentration is in relatively lower state, makes the whole uneven concentration of dye liquor in the dye vat from this, this the poor condition of level-dyeing nature appears easily in actual dyeing process. When the circulating system and different areas at the bottom of the dye vat are provided with the longitudinal circulating reflux connectors, the probability that the dye liquor in different areas at the bottom of the dye vat participates in circulation is more equal, so that the phenomena of more circulating times and low concentration of the part of the dye liquor can be effectively reduced, the phenomenon of uneven concentration of the whole dye liquor is improved, and the level dyeing rate is improved.
The following is an analysis made by the inventors of the present application of the principle of the above-described method of the present application in terms of improving the dyeing efficiency:
it has been analyzed in the above description that when the circulating system and the dye vat have only one longitudinal circulating-returning connection port, the dye liquor close to the longitudinal circulating-returning connection port of the dye vat has a large number of circulating times and a relatively low concentration, and the dye liquor is the part of the dye liquor which returns to the nozzle and dyes the fabric, and the low concentration means that the dye in the dye liquor is small, and means that the dye diffused into the fabric fiber is less when the dye liquor contacts the fabric each time, thereby means that the dyeing requirement can be met by circulating more times, thereby prolonging the dyeing time and reducing the dyeing efficiency. The method can weaken the current situation that the circulation times of part of the dye liquor are large and the concentration is low, so that the concentration of the dye liquor and the amount of the dye diffused into the fabric fiber when the dye liquor contacts with the fabric each time are improved, the dyeing requirement can be met by the aid of fewer circulation times, the dyeing time is shortened, and the dyeing efficiency is improved.
The following is an analysis made by the inventors of the present application of the principle of the above-described method of the present application in reducing the bath ratio:
for contact exchange dyeing, the exchange frequency is increased, so that the effect of the original dye liquor can be achieved by using a smaller amount of dye liquor, namely, the bath ratio can be reduced by increasing the exchange frequency. In order to increase the frequency of switching, the following methods are mainly used in the related art: firstly, the amount of dye liquor outside the dye vat is reduced by improving the internal structure of the circulating pump or shortening the length of the pipeline, but the method has limitations; and secondly, the power of the circulating pump is increased to improve the circulating rate of the dye liquor, but the load and the energy consumption of the circulating pump are increased, and the jet force of the dye liquor at the nozzle is increased, so that the fabric is deformed.
It has been analyzed in the above description that the dye liquor close to the longitudinal recirculation connection port can be extracted directly so as to ensure a proper circulation and exchange frequency. And the dye liquor far away from the longitudinal circulation backflow connecting port can enter the next circulation only by flowing to the longitudinal circulation backflow connecting port, so that the circulation frequency of the part of the dye liquor far away from the longitudinal circulation backflow connecting port is actually reduced, the exchange frequency of the part of the dye liquor is reduced, the integral exchange frequency of the dye liquor is reduced, and the bath ratio is not adjustable. And when the circulating system and the different areas of dye vat bottom all have the longitudinal circulation backward flow connector, can effectively improve the phenomenon that the exchange frequency of the dye liquor of keeping away from the longitudinal circulation backward flow connector in traditional circulating system is low, can guarantee the holistic exchange frequency of dye liquor from this, so, adopt little bath ratio also can satisfy the dyeing demand.
In summary, the present application can simultaneously improve level-dyeing property, improve dyeing efficiency and reduce bath ratio by increasing the longitudinal circulation reflux connection port of the dye vat, which is not achieved by the existing circulation method at present, is a new inventive concept different from the existing related technology, and has outstanding substantive features and obvious progress for the field.

The inventor considers that the same is related to the pumping of the dye liquor by the longitudinal circulating pump, when the longitudinal circulating return pipe is directly communicated with the longitudinal circulating pump, the path of all the dye liquor entering the circulation is more favorably shortened, the contact exchange frequency and the uniformity of the contact exchange frequency are improved, and the level dyeing property, the dyeing efficiency and the bath ratio are further improved.

Detailed Description
The present application is described in further detail below.
The circulation system of a conventional dyeing machine, as shown in figure 1, comprises a longitudinal circulation pump for driving the circulation of the dyeing liquor connected between the bottom of the vat and the nozzle of the spraying device, and a longitudinal circulation return pipe connecting the bottom of the vat, the longitudinal circulation pump and the nozzle. Under the drive of the longitudinal circulating pump, the dye liquor at the bottom of the dye vat flows back to the nozzle at the top of the dye vat through the longitudinal circulating return pipe so as to be used for dyeing fabrics.
Example 1
A method for low bath ratio fast level dyeing, as shown in fig. 2, the longitudinal circulation system of a traditional dyeing machine is regulated: the longitudinal circulating system comprises a longitudinal circulating pump which is connected between the bottom of the dye vat and a nozzle of the spraying device and is used for driving the circulation of the dye liquor, and a longitudinal circulating pipeline which is connected with the bottom of the dye vat, the longitudinal circulating driving part and the nozzle; arranging a longitudinal circulating pipeline between a longitudinal circulating pump and the bottom of the dye vat into a form of containing a plurality of longitudinal circulating return pipes; the connecting part of the longitudinal circulation backflow pipe and the dye vat is a longitudinal circulation backflow connecting port, so that the longitudinal circulation backflow connecting ports are distributed at the bottom of the dye vat at intervals.
The method has the advantages of simultaneously improving the leveling property, improving the dyeing efficiency and reducing the bath ratio. For the principle of action of the present application, the following analysis is made.
Improving the leveling property: when the circulating system and the dye vat only have one longitudinal circulating reflux connecting port, the dye liquor is extracted from the dye vat close to the longitudinal circulating reflux connecting port by each circulation of the circulating pump, and the part of the dye liquor is conveyed to the nozzle for next contact exchange dyeing with the fabric, and the dye liquor of the dye vat far away from the longitudinal circulating reflux connecting port can reach the longitudinal circulating reflux connecting port and be extracted after flowing through a long path. Because every contact exchange dyeing all can make the dye liquor concentration appear the decline phenomenon, along with the continuous going on of dyeing process, compare with whole dye liquor in the dye vat, the number of cycles that the dye liquor that is close to the longitudinal circulation backward flow connector of dye vat participates in is many, the concentration is in relatively lower state, makes the whole uneven concentration of dye liquor in the dye vat from this, this the poor condition of level-dyeing nature appears easily in actual dyeing process. When the circulating system and different areas at the bottom of the dye vat are provided with the longitudinal circulating reflux connectors, the probability that the dye liquor in different areas at the bottom of the dye vat participates in circulation is more equal, so that the phenomena of more circulating times and low concentration of the part of the dye liquor can be effectively reduced, the phenomenon of uneven concentration of the whole dye liquor is improved, and the level dyeing rate is improved.
The dyeing efficiency is improved: when the circulating system and the dye vat only have one longitudinal circulating reflux connecting port, the dye liquor close to the longitudinal circulating reflux connecting port of the dye vat has more circulation times and relatively low concentration, the part of the dye liquor reflows to the nozzle and dyes the fabric, the low concentration means less dye in the dye liquor, and the dye diffused into the fabric fiber is less when the dye liquor contacts the fabric each time, so that the dyeing requirement can be met by more circulation times, the dyeing time is prolonged, and the dyeing efficiency is reduced. The method can weaken the current situation that the circulation times of part of the dye liquor are large and the concentration is low, so that the concentration of the dye liquor and the amount of the dye diffused into the fabric fiber when the dye liquor contacts with the fabric each time are improved, the dyeing requirement can be met by the aid of fewer circulation times, the dyeing time is shortened, and the dyeing efficiency is improved.
And (3) reducing the bath ratio: the dye liquor close to the longitudinal circulation backflow connecting port can be directly extracted, so that normal circulation and exchange frequency can be guaranteed. And the dye liquor far away from the longitudinal circulation backflow connecting port can enter the next circulation only by flowing to the longitudinal circulation backflow connecting port, so that the circulation frequency of the part of the dye liquor far away from the longitudinal circulation backflow connecting port is actually reduced, the exchange frequency of the part of the dye liquor is reduced, the integral exchange frequency of the dye liquor is reduced, and the bath ratio is not adjustable. And when the circulating system and the different areas of dye vat bottom all have the longitudinal circulation backward flow connector, can effectively improve the phenomenon that the exchange frequency of the dye liquor of keeping away from the longitudinal circulation backward flow connector in traditional circulating system is low, can guarantee the holistic exchange frequency of dye liquor from this, so, adopt little bath ratio also can satisfy the dyeing demand.
Furthermore, the inventor intends to explain that, compared with the mode that a plurality of longitudinal circulation return pipes are converged into a pipeline and then are led into a longitudinal circulation pump, the mode that the plurality of longitudinal circulation return pipes are directly led into the longitudinal circulation pump through the plurality of liquid inlets by adopting the longitudinal circulation pump with the plurality of liquid inlets is beneficial to further strengthening the advantages of the application in the aspects of improving the level-dyeing property, improving the dyeing efficiency and reducing the bath ratio. The inventor considers that the same is related to the pumping of the dye liquor by the longitudinal circulating pump, when the longitudinal circulating return pipe is directly communicated with the longitudinal circulating pump, the path of all the dye liquor entering the circulation is more favorably shortened, the contact exchange frequency and the uniformity of the contact exchange frequency are improved, and the level dyeing property, the dyeing efficiency and the bath ratio are further improved.
