[0023] The preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0024] As used herein, the term "including" and its variations mean open inclusion, i.e., "including but not limited to". Unless otherwise stated, the term "or" means "and / or". The term "based on" means "based at least in part on". The terms "an example embodiment" and "an embodiment" mean "at least one example embodiment". The term "another embodiment" means "at least one additional embodiment". The terms "first", "second", etc. may refer to different or the same objects.

[0025] As described above, natural plant extracts can be used as dyeing liquid to dye fabrics such as silk protein fabrics or plant fiber fabrics. For example, yam is often used in the dyeing process of Xiangyunsha. Specifically, in the traditional Xiangyunsha dyeing process, the yarn blank is impregnated with yam juice, and the impregnated yarn blank is placed in the sun for exposure. After repeated several times, mud, washing, drying and other processes are performed, so that the Xiangyunsha can be dyed.

[0026] However, in practice, all the processes in the above Xiangyun yarn dyeing process must be completed by manpower. For example, workers need to press the yarn blank into the yam juice by hand and constantly turn the yarn blank in the yam juice so that all parts of the yarn blank are stained with the yam juice. For another example, during the drying process, workers need to place bamboo poles to press the Xiangyun yarn to ensure that the Xiangyun yarn is flat against the grass, and they also need to frequently kick the bamboo poles to move their positions to prevent the parts of the Xiangyun yarn pressed by the bamboo poles from drying.

[0027] In summary, the shortcomings of traditional fabric dyeing solutions are: excessive reliance on manual operation, low dyeing efficiency, and different climatic conditions and operations of different workers can easily cause unstable and uneven fabric dyeing effects.

[0028] In order to at least partially solve one or more of the above-mentioned problems and other potential problems, an exemplary embodiment of the present invention proposes a device for fabric dyeing, by making the device include: a dyeing trough and a lighting unit arranged in sequence and at intervals along the winding direction of the fabric, wherein the dyeing trough is configured to contain dye liquid for dyeing the fabric transferred thereto, and the lighting unit is arranged at the outlet side of the dyeing trough and is configured to illuminate the fabric transferred thereto so as to change the color of the dyed fabric. The present invention can automatically perform processes such as dyeing and lighting on the fabric, thereby improving the efficiency of fabric dyeing; in addition, by making the lighting unit include at least one cylindrical lighting mechanism, the cylindrical lighting mechanism at least includes an outer shell and a light-emitting device arranged inside the outer shell, the present invention can provide controllable and stable lighting to the fabric to achieve exposure of the fabric, avoid the influence of adverse climates such as cloudy days and rainy days on fabric dyeing, and improve the stability and uniformity of the fabric dyeing effect.

[0029] The following will be combined Figures 1 to 5 , the device for fabric dyeing provided by the present invention is described in detail. The "fabric" herein may refer to, for example, silk protein fabric, plant fiber fabric, etc., but is not limited thereto. In some embodiments, the fabric may be a silk protein fabric for forming Xiangyun yarn.

[0030] Figure 1 Schematic diagram of an apparatus 100 for dyeing fabric according to some embodiments of the present invention is shown. Figure 1 As shown, the device 100 includes a dyeing tank 110 and an illumination unit 120 arranged in sequence along the winding direction of the fabric, and the illumination unit 120 is arranged at the outlet side of the dyeing tank 110.

In some embodiments, the concentration detection unit may also be replaced by a sugar content detection unit or a density detection unit to determine the concentration of the dye solution in the chamber 112 by collecting the sugar content or density of the dye solution in the chamber 112.

[0038] The liquid inlet and the liquid outlet can be used to add dye solution into the chamber 112 and to discharge the dye solution from the chamber 112 , respectively, so as to reduce the liquid level of the dye solution in the chamber 112 .

In some examples, the cloth receiving unit may optionally include one or more of the following devices: for example, a drying device for drying the fabric output from the illumination unit 120, a winding device for winding the fabric, a stacking device for stacking the fabric after drying, etc.

[0043] According to some further embodiments of the present invention, the device 100 may further include a control unit (not shown) for controlling the device 100 .

[0044] Regarding the control unit 160, it may have one or more integrated or discrete processing units, including special processing units such as a graphics processing unit (GPU), a field programmable gate array (FPGA), and an application-specific integrated circuit (ASIC), as well as a general processing unit such as a CPU.

[0045] According to an embodiment of the present invention, the control unit may be connected to other units in the device 100, such as Figure 1The dye tank 110 and the illumination unit 120 shown in the figure, as well as the cloth supply unit, the cloth receiving unit, etc. not shown in the figure, exchange data via wired or wireless means. In some examples, the control unit can control the temperature, liquid level, and concentration of the dye liquid in the dye tank 110 via wired or wireless means. For example, the control unit can control the temperature sensor in the temperature control unit of the dye tank 110 to detect the temperature of the dye liquid in the chamber, and control the heater based on the detected temperature of the dye liquid so that the dye liquid in the chamber maintains a predetermined temperature; the control unit can also control the liquid level detection unit of the dye tank 110 to detect the liquid level of the dye liquid in the chamber, and control the liquid inlet to add the dye liquid to the chamber or control the liquid outlet to discharge the dye liquid from the chamber based on the detected liquid level of the dye liquid, so that the liquid level of the dye liquid in the chamber is maintained at a predetermined height; the control unit can also control the concentration detection unit of the dye tank 110 to detect the concentration of the dye liquid in the chamber, and determine whether the concentration of the dye liquid in the current chamber meets the predetermined condition based on the detected concentration of the dye liquid.

[0046] Figure 2 FIG. 2 shows a schematic diagram of a cylindrical illumination mechanism 200 according to an embodiment of the present invention. Figure 2 As shown, the cylindrical lighting mechanism 200 includes a cylinder 221, a housing 222 and a light emitting device 223 disposed inside the housing. It should be understood that the cylindrical lighting mechanism 200 may further include additional units not shown, and the scope of the present invention is not limited in this respect.

[0047] Regarding the cylinder 221, its axis may coincide with the axis of the cylindrical illumination mechanism 200. According to an embodiment of the present invention, the axis of the cylinder 221 may be configured to be coupled with a rotating mechanism so that the cylinder 221 may rotate around the axis of the cylindrical illumination mechanism 200, thereby driving the fabric on the cylinder to rotate with the cylinder 221 to realize the transmission of the fabric in the cylindrical illumination mechanism 200. For example, in some embodiments, the fabric may be transmitted along the outer side wall of the cylinder 221.

[0048] Regarding the housing 222, it can be arranged at the periphery of the cylindrical illumination mechanism 200, so that a cavity is formed between the housing 222 and the cylinder 221, for accommodating the light emitting device 223. In some embodiments of the present invention, the side of the housing 222 facing the cylinder 221 is set as a mirror surface, so that the light emitted by the light emitting device 223 can be reflected back to the cylinder 221 via the mirror surface, so as to illuminate the fabric transmitted along the outer side wall of the cylinder 221, thereby improving the illumination efficiency of the fabric.

[0049] Regarding the light emitting device 223, it can be configured to be arranged around the cylinder 221 to provide illumination to the fabric transmitted on the outer wall of the cylinder 221. According to an embodiment of the present invention, the light emitting device 223 can be configured to emit light of a predetermined wavelength. For example, in some embodiments, the light emitting device 223 can be configured to emit light with a wavelength range of less than or equal to 500nm (such as light with a wavelength of less than or equal to 500nm and greater than or equal to 200nm, light with a wavelength of less than or equal to 400nm, or light with a wavelength of less than or equal to 200nm). Further, in some examples, of all the light emitted by the light emitting device 223, the radiation amount of light with a wavelength of less than or equal to 500nm and greater than or equal to 200nm can account for at least 10% of the total radiation amount of all the light; in some other examples, the radiation amount of light with a wavelength of less than or equal to 400nm can account for more than 50% of the total radiation amount of all the light.

[0050] According to some embodiments of the present invention, the light emitting device 223 may include a plurality of light emitting tubes arranged in parallel, and each light emitting tube is at the same distance from the outer wall of the cylinder 221, whereby the fabric transmitted along the outer wall of the cylinder can be exposed to light of equal intensity, thereby improving the uniformity of fabric dyeing.

[0051] like Figure 2 As shown, the cylindrical illumination mechanism 200 may further include: a first guide wheel 224A and a second guide wheel 224B, wherein the first guide wheel 224A is configured to allow the fabric to be transferred to the inside of the cylindrical illumination mechanism 200 via the first guide wheel 224A, and the second guide wheel 224B is configured to allow the fabric to be output from the cylindrical illumination mechanism 200 via the second guide wheel 224B. Specifically, the fabric may be transferred to the inside of the cylindrical illumination mechanism 200 via the first guide wheel 224A, and the fabric may be attached to the outer wall of the cylinder 221 under the guidance of the first guide wheel 224A, so that the fabric can be transferred clockwise along the outer wall of the cylinder 221 to the second guide wheel 224B, and output from the cylindrical illumination mechanism 200 via the second guide wheel 224B.

[0052] In summary, through Figure 2 In the cylindrical lighting mechanism 200 shown, the distance between the light emitting device 223 and the outer wall of the cylinder 221 is the same at all locations, and the fabric is transmitted along the outer wall of the cylinder 221, that is, the distance between the light emitting device 223 and the fabric can remain unchanged, so that the fabric receives the same light intensity, thereby improving the uniformity of fabric dyeing.

[0053] Further, according to the concept of the present invention, the number of cylindrical illumination mechanisms included in the illumination unit can be set according to the desired color of the fabric. In other words, the illumination unit can include one or more cylindrical illumination mechanisms for illuminating the dyed fabric.

[0054] Figure 3 A schematic diagram of an apparatus 300 for dyeing fabric according to some other embodiments of the present invention is shown. It should be understood that the apparatus 300 may further include additional units not shown, and the scope of the present invention is not limited in this respect.

[0055] like Figure 3 As shown, the device 300 includes a dyeing tank 310, an illumination unit 320 and a cloth tightening device 330 which are arranged in sequence along the winding direction of the fabric, wherein the illumination unit 320 includes two cylindrical illumination mechanisms, namely a first cylindrical illumination mechanism 321 and a second cylindrical illumination mechanism 322.

[0056] Regarding the dyeing tank 310, it may have the same Figure 1 The dyeing tank 110 has the same structure as the dyeing tank 110, which will not be described here.

[0057] The first cylindrical illumination mechanism 321 and the second cylindrical illumination mechanism 322 may both have the same Figure 2 The cylindrical illumination mechanism 200 has the same structure as the cylindrical illumination mechanism 200, which will not be described here. In this embodiment, the fabric dyed by the dyeing tank 310 is successively illuminated by the first cylindrical illumination mechanism 321 and the second cylindrical illumination mechanism 322, so that the color of the fabric can reach a predetermined color. According to the inventive concept of the present invention, the wavelengths of the light emitted by the light emitting devices in the first cylindrical illumination mechanism 321 and the second cylindrical illumination mechanism 322 can be the same or different.

[0058] On this basis, in some other examples of the present invention, the first cylindrical lighting mechanism 321 and the second cylindrical lighting mechanism 322 can be used to perform lighting treatment on different surfaces of the fabric respectively.

[0059] Regarding the cloth tightening device 330, it can be used to adjust the warp tension of the fabric so that the fabric transmitted through the device 300 can meet the warp tension requirement. The cloth tightening device 330 can be a bracket, a cloth tightening rod, a tension adjustment mechanism, etc. Further, as Figure 3 As shown, the cloth tightening device 330 may further include a cloth collecting unit 331 for collecting the fabric output by the illumination unit 320. For the cloth collecting unit 331, reference may be made to the above description of Figure 1 The description will not be repeated here.

[0060] In some other embodiments of the present invention, the illumination unit of the device provided by the present invention may additionally include a plate-shaped illumination mechanism for illuminating the dyed fabric.

[0061] Figure 4 A schematic diagram of an apparatus 400 for dyeing fabric according to yet other embodiments of the present invention is shown. It should be understood that the apparatus 400 may further include additional units not shown, and the scope of the present invention is not limited in this respect.

[0062] like Figure 4 As shown, the device 400 includes a dyeing tank 410, an illumination unit 420 and a cloth tightening device 430 which are arranged in sequence along the winding direction of the fabric, wherein the illumination unit 420 includes a plate-shaped illumination mechanism 421, a first cylindrical illumination mechanism 422 and a second cylindrical illumination mechanism 423.

[0063] Regarding the plate-shaped illumination mechanism 421, it can be arranged between the dyeing tank and the cylindrical illumination mechanism. Figure 4 In the example shown, the plate-shaped illumination mechanism 421 is disposed between the dyeing tank 410 and the first cylindrical illumination mechanism 422. Figure 5 The structure of the plate-shaped illumination mechanism 421 is further described.

[0064] Figure 5 A schematic diagram of a plate-shaped illumination mechanism 421 according to an embodiment of the present invention is shown.

[0065] like Figure 5 As shown, the plate-shaped illumination mechanism 421 includes: a vertically arranged flat plate-shaped double-sided light-emitting device 425 , and a fabric roller 427 arranged above the flat plate-shaped double-sided light-emitting device 425 .

[0066] Regarding the flat double-sided light emitting device 425, it can be arranged in the cavity of the plate-shaped illumination mechanism 421 to illuminate the fabric transmitted to the inside of the flat double-sided light emitting device 425. According to an embodiment of the present invention, the flat double-sided light emitting device 425 may include a plurality of light emitting tubes arranged in parallel on the same vertical plane. Similarly, the flat double-sided light emitting device 425 can be configured to emit light of a predetermined wavelength. For example, in some embodiments, the flat double-sided light emitting device 425 can be configured to emit light with a wavelength range of less than or equal to 500nm (such as light with a wavelength less than or equal to 500nm and greater than or equal to 200nm, light with a wavelength less than or equal to 400nm, or light with a wavelength less than or equal to 200nm).

[0067] Regarding the fabric drum 427, it can be arranged inside the flat double-sided light emitting device 425, so that the fabric transmission path inside the flat double-sided light emitting device 425 includes one or more rotating fabric running sections. By arranging the flat double-sided light emitting device 425 in the space surrounded by the rotating fabric running sections, one side of the fabric transmitted in the rotating fabric running sections can be illuminated by the light emitted by the flat double-sided light emitting device 425.

[0068] According to an embodiment of the present invention, the flat-plate double-sided light-emitting device 425 is at the same distance from the left and right side walls of the plate-shaped lighting mechanism 421, and the fabric roller 427 is arranged directly above the flat-plate double-sided light-emitting device 425, so that during the transmission of the fabric in the plate-shaped lighting mechanism 421, the fabric can be simultaneously illuminated by both sides of the flat-plate double-sided light-emitting device 425, which significantly improves the utilization rate of the light-emitting device and shortens the time required for the color change of the fabric.

[0069] like Figure 5 As shown, the plate-shaped illumination mechanism 421 may further include: a third guide wheel 429A and a fourth guide wheel 429B, wherein the third guide wheel 429A is configured to allow the fabric to be transferred to the inside of the plate-shaped illumination mechanism 421 via the third guide wheel 429A, and the fourth guide wheel 429B is configured to allow the fabric to be output from the plate-shaped illumination mechanism 421 via the fourth guide wheel 429B. Specifically, the fabric may be transferred to the inside of the plate-shaped illumination mechanism 421 via the third guide wheel 429A, and then transferred through the rotary cloth feeding section via the fabric roller 427, and then output from the plate-shaped illumination mechanism 421 via the fourth guide wheel 429B.

[0070] In some other embodiments, the plate-shaped illumination mechanism 421 may further include a temperature regulating device so that the temperature inside the plate-shaped illumination mechanism 421 is controllable. Additionally, the plate-shaped illumination mechanism 421 may include a heat preservation structure, for example, the plate-shaped illumination mechanism 421 may be designed to be airtight so as to control the evaporation rate of water. In other embodiments, the plate-shaped illumination mechanism 421 may further include a circulating air device so that the humidity inside the plate-shaped illumination mechanism 421 is adjustable. According to the present invention, the temperature and humidity inside the plate-shaped illumination mechanism 421 are controlled so that the color change of the fabric is uniform.

[0071] In summary, by using Figure 5 The plate-shaped lighting mechanism 421 shown can make use of the double-sided luminous property of the flat double-sided light-emitting device 425, and use the two luminous surfaces of the flat double-sided light-emitting device 425 to simultaneously illuminate the fabric, so as to improve the utilization rate of the light-emitting device, shorten the time required for the color change of the fabric, and further improve the efficiency of fabric dyeing.
