Preferably, in the washing process, the temperature is preferably controlled to be between 85 and 100 ℃, and an excessively high temperature cannot be adopted, so that the fabric has insufficient color vividness and loses light color.

Preferably, a proper amount of citric acid aid is added in the washing process, and the addition of the citric acid aid can ensure that the brightness of the fabric color is more saturated and the instability of color fastness can be controlled. In the embodiment of the invention, the amount of citric acid aid added is determined according to the size of the dye vat and the thickness of the fabric, and is generally about 1/10, and excessive amounts will result in unacceptable pH.

In conclusion, the processing method of the wool fabric provided by the invention has the advantages that the wool yarn is woven into the grey fabric, the grey fabric is bleached, treated at high temperature for shaping, the upper yarn slurry is dried, then the digital printer is used for spray painting operation, and the fabric subjected to the spray painting operation is subjected to sealing evaporation, high-temperature washing and high-temperature shaping, so that the purpose of performing high-quality digital printing on the wool fabric is realized.

From another aspect, the process steps and effects of the method for processing and treating digital printed wool fabric according to the present invention are described in more detail with reference to fig. 1 and 2.

FIG. 1 is a flow chart of steps of a processing method of a digital printed wool fabric. As shown in figure 1, the processing method of the digital printed wool fabric comprises the following steps:

and step S1, weaving the wool yarns into grey cloth, bleaching the grey cloth to enable the color of the fabric to be a bleached color, and then carrying out high-temperature treatment and shaping. In the specific implementation of the invention, 66 Australian wool yarns, yarns with the twist number of not less than 1200 and 1250 (the sliver rotates 360 degrees around the axis of the sliver to form one twist), after being woven into grey cloth, the grey cloth is bleached for 20-30 minutes, and then the grey cloth is shaped at the high temperature of 100 and 110 degrees, so that the width of the grey cloth is uniform.

And step S2, applying cotton yarn slurry on the fabric after high-temperature setting, and drying. In the specific embodiment of the invention, the fabric after high-temperature setting is subjected to cotton yarn sizing agent at 90-110 ℃ and is dried at the same time.

And step S3, spreading the fabric coated with the sizing agent on a digital printer, performing spray painting operation, directly spraying and painting on the wool fabric, and simultaneously drying and rolling the fabric to enable the color to permeate into the fabric. In the embodiment of the invention, before the spray painting operation is executed, the printing size and the color plate are adjusted, then the fabric coated with the sizing agent is flatly laid on a digital printer table, is set through a computer program, is directly sprayed and painted on the wool fabric, and is dried and rolled at the same time, so that the color permeates into the fabric.

And step S4, sealing and steaming the fabric processed in the step S3 to stabilize and thoroughly infiltrate the color into the yarns of the fabric. In the embodiment of the invention, the fabric processed in the step S3 is put into a steam box with the temperature of 100-110 ℃ for sealing and steaming, so that the stable color can be more thoroughly infiltrated into the yarns of the fabric.

Preferably, the fabric is placed in the steamer while a barrier, such as a backing cloth, is placed on the surface of the fabric to prevent staining of the fabric when the fabric rolls in the steamer.

Preferably, in order to ensure the qualified color fastness, the steamed fabric needs to be cooled for about 30 minutes to ensure the qualified color fastness.

And step S5, washing the steamed fabric with high-temperature water to wash off the loose color on the surface of the fabric. In the specific embodiment of the invention, the step of high-temperature washing is carried out in the overflow cylinder, the washing time is preferably 30-50 minutes, namely, the steamed fabric is put into the overflow cylinder and washed by high-temperature washing for 30-50 minutes to remove the loose color on the surface of the fabric. Preferably, in the washing process, the temperature is preferably controlled to be between 85 and 100 ℃, and an excessively high temperature cannot be adopted, so that the fabric has insufficient color vividness and loses light color.

Preferably, a proper amount of citric acid aid is added in the washing process, and the addition of the citric acid aid can ensure that the brightness of the fabric color is more saturated and the instability of color fastness can be controlled. In the embodiment of the invention, the amount of citric acid aid added is determined according to the size of the dye vat and the thickness of the fabric, and is generally about 1/10, and excessive amounts will result in unacceptable pH.

And step S6, performing high-temperature shaping on the fabric after washing to ensure the uniformity of the fabric width. In the embodiment of the invention, the washed fabric enters the high-temperature setting machine at the temperature of 100-.

Experiments prove that the digital printing and spray-painting of the wool fabric can be well realized by the processing method, as shown in figure 2, the digital printing process breaks through the rigid property of the traditional wool fabric, various beautiful patterns can be clearly printed on the thick wool fabric like photos by digital spray-painting, and the application universality of the wool fabric is improved.

In conclusion, the processing method of the digital printing wool fabric provided by the invention has the advantages that the wool yarns are woven into the grey fabric, the grey fabric is bleached, treated at high temperature for shaping, the upper yarn slurry is dried, then the digital printer is used for carrying out the spray painting operation, and the fabric subjected to the spray painting operation is subjected to sealing evaporation, high-temperature washing and high-temperature shaping, so that the purpose of carrying out high-quality digital printing on the wool fabric is realized.

In addition, the inventor also finds that: when the sharpness of a printed and dyed image is changed drastically, the dyeing effect, including indexes such as color fastness and color saturation, cannot reach a better level easily because the dynamic performance of a driving motor connected with a nozzle is not enough to drive the nozzle to eject corresponding dye with enough mechanical dynamics, so that the color is switched quickly at a local position of a wool fabric. But this reduces the efficiency and speed of the overall dyeing process. The inventors therefore propose a new concept with the object of driving the head to operate at a higher speed (without having to decelerate) and with a precise spray volume, i.e. to obtain sufficient mechanical dynamic performance of the head, by giving a new driving method to the motor connected to the head so that the electrical energy of the motor can be output with superior dynamic performance when the head passes through a partial image in which the sharpness changes drastically.

Preferably, the first and second power storage assemblies are connected to a motor for driving the nozzle, so that enough electric energy is stored for supplying the motor with larger electric energy in real time when the image sharpness of the printing is larger or the image sharpness change rate is larger, and the motor has larger dynamic performance. The rate of change of image sharpness is greater than 35% per 0.1 second, or greater than 75% per inch of length of print, then in one embodiment the method shown in figure 3 is proposed for the management of electrical power drive to the motor. In an embodiment illustrated in fig. 3, a method for managing regulation of power output of a first electrical storage component and a second electrical storage component coupled in series to power a motor driving a spray head is presented, comprising:

utilizing one or more switching cells in a first switching on-off mode to couple a drive motor in parallel to the first electrical storage component during charging in step S3-1;

in step S3-2, calculating/defining a first battery characteristic curve of the first power storage assembly during charging, using an energy storage control unit;

in step S3-3, calculating/defining a second battery characteristic curve of the second power storage assembly during charging, using the energy storage control unit;

in step S3-4, calculating/defining, with the energy storage control unit, a second switching on-off pattern to be implemented to the one or more switching cells from the first battery characteristic curve and a second battery characteristic curve, wherein the second switching on-off pattern couples the drive motor in parallel to the second electrical storage component during charging; and

in step S3-5, a second switching on/off pattern is implemented on the one or more switching cells using the control circuit.

Optionally, in the electrical energy output regulation method of some embodiments, the first battery characteristic curve comprises a first potential difference across an anode and a cathode of the first electrical storage component, and wherein the second battery characteristic curve comprises a second potential difference across an anode and a cathode of the second electrical storage component.

Optionally, in the power output regulation method of some embodiments, wherein calculating/defining the second switching on/off pattern to be implemented to the one or more switching cells according to the first battery characteristic curve and the second battery characteristic curve comprises calculating/defining a difference between the first potential difference and the second potential difference.

Optionally, in the power output adjustment method of some embodiments, the first battery characteristic curve includes a first accumulated time during which the first electrical storage assembly is coupled to the drive motor, and wherein the second battery characteristic curve includes a second accumulated time during which the second electrical storage assembly is coupled to the drive motor.

Optionally, in the power output regulation method of some embodiments, calculating/defining the second switch on-off pattern to be implemented to the one or more switch units according to the first and second battery characteristics includes calculating/defining a difference between the first and second accumulated times.

Optionally, in the power output regulation method of some embodiments, further comprising calculating/defining a local charging parameter, wherein the local charging parameter comprises a preferred parameter mode for charging at a high voltage.

Optionally, in some embodiments, the method further comprises calculating/defining the series coupling of the first and second power storage assemblies at least partially according to the local charging parameter.

Optionally, in the power output regulation method of some embodiments, further comprising identifying whether an abnormality has occurred in the first power storage assembly or the second power storage assembly, wherein the calculating/defining of the second switching on/off pattern to be applied to the one or more switching units is further based at least in part on whether an abnormality has occurred based on the first battery characteristic curve and the second battery characteristic curve.

Optionally, in the power output regulating method of some embodiments, implementing a second switching on-off pattern to the one or more switching units further comprises: a pre-charge configuration is implemented at the one or more switching cells to reduce inrush current.

Optionally, in the power output regulation method of some embodiments, further comprising calculating/defining an elapsed time since a previous change in the switch configuration, wherein the calculating/defining the implementing of the second switch on/off pattern to the one or more switch units is further based at least in part on the elapsed time according to the first and second battery characteristics.

The first switch on-off pattern of one or more switches in these embodiments may also be referred to as: the first switch configuration may be understood or implemented as: for example, there are 3 switches SW1, SW2, SW 3. Wherein SW1, SW2 are in the on (power on) state and SW3 is in the off state. The on-off state of the switch is adjusted continuously according to the ink jet amount of the nozzle or the change percentage of the local sharpness in the design color, so that a driving force with better dynamic performance is given to the nozzle. For example, at other times it may become that all three switches SW1, SW2, SW3 are in an on state, or SW1 is in an on state, and SW2, SW3 are in an off/off state, which may be referred to as: a second switch on-off pattern.

In addition, the inventor also finds that: when the sharpness of the printed and dyed image is changed violently, the dyeing effect including indexes such as color fastness and color saturation cannot reach a better level easily in a high-temperature/normal-temperature state, and the dyeing pigment is likely to disperse on the wool fabric rather than gather and carry out local adhesion in the high-temperature/normal-temperature state, so that local color mixing is caused, the blurring degree of the image is improved, the color fidelity is reduced, and the sharpness of the image is also reduced. Therefore, the inventors propose a concept of reducing the temperature of the printing environment of the wool fabric with a temperature control curve having a certain gradient change characteristic when printing partial images having a large image sharpness change rate.

Preferably, the rate of change of image sharpness is greater than 35% per 0.1 second, or the rate of change of image sharpness of the print is greater than 75% per inch of length of the print, reducing the ambient temperature of the wool face fabric by a temperature gradient greater than 52 ℃/s.

The foregoing embodiments are merely illustrative of the principles and utilities of the present invention and are not intended to limit the invention. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the present invention. Therefore, the scope of the invention should be determined from the following claims.

In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Hardware Description Language), traffic, pl (core universal Programming Language), HDCal (jhdware Description Language), lang, Lola, HDL, laspam, hardward Description Language (vhr Description Language), vhal (Hardware Description Language), and vhigh-Language, which are currently used in most common. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.

The control unit may be implemented in any suitable way, for example, the control unit may take the form of, for example, a microprocessor or processor and a computer readable medium storing computer readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic control unit, and an embedded micro-control unit, examples of which include, but are not limited to, the following micro-control units: the ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20 and Silicone Labs C8051F320, the memory control unit may also be implemented as part of the control logic of the memory. Those skilled in the art will also appreciate that instead of implementing the control unit in pure computer readable program code, it is entirely possible to logically program the method steps such that the control unit performs the same functions in the form of logic gates, timers, flip-flops, switches, application specific integrated circuits, programmable logic control units, embedded micro control units, etc. Such a control unit may thus be regarded as a hardware component and the means included therein for performing the various functions may also be regarded as structures within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.
