Description

Technical Field

[0001] The utility model generally relates to fabric dyeing, and in particular to a dyeing device and a dyeing system for performing a dyeing process on a target fabric. Background Art

[0002] The traditional scheme of using dyes containing natural plant extracts to color the target fabric usually includes: manually and repeatedly dyeing the target fabric with dyes containing natural plant extracts, and repeatedly using sunlight to dry the dyed target fabric. Taking the coloring method of Xiangyunsha as an example, it usually includes: manually soaking the mulberry silk fabric in yam juice, then laying the soaked mulberry silk fabric on the grass to dry it in the sun, and then repeatedly soaking and drying it until the mulberry silk fabric presents the target color (such as brown). Subsequently, iron-rich mud is used to apply it on one side, and it is laid flat in the sun for exposure, and then it undergoes cleaning and other processes to finally form Xiangyunsha.

[0003] In the above-mentioned traditional schemes, there is no machinery or equipment for continuous dyeing and coloring of the target fabric, and the traditional dyeing efficiency of manual dyeing and sun exposure is low. In addition, the manual dyeing and sun exposure methods are prone to cause the dyeing effect to be easily affected by weather changes, temperature and humidity differences at the paving position, and present an unstable and uneven state. For example, the dyeing effect between target fabrics of the same process and different batches is quite different, and the dyeing of different areas of the same target fabric is uneven and uneven in depth. In addition, the manual soaking, paving and drying methods result in low dyeing efficiency.

[0033] As described above, the conventional scheme for coloring a target fabric has the following disadvantages: the dyeing effect of dyeing with a dye containing a natural plant extract is unstable and uneven, and the dyeing efficiency is low.

[0034] In order to at least partially solve one or more of the above problems and other potential problems, an exemplary embodiment of the present invention proposes a coloring device for coloring a target fabric, wherein the coloring device includes: a dipping unit, a light source irradiation area (including a box and a light source) and a transmission device, and the dipping unit performs an infiltration treatment on the target fabric input into the dipping treatment liquid (the dipping treatment liquid contains a natural plant extract); the light source irradiation area is configured to perform an irradiation treatment for a predetermined time on the target fabric input into the light source irradiation area so that the color of the target fabric changes, and the light source includes a light wave with a wavelength that meets a predetermined wavelength range; and The transmission device is configured to at least input and output the target fabric into and out of the light source irradiation area. The utility model can automatically and continuously complete the impregnation and irradiation treatment of the target fabric without manual impregnation, tiling and sun exposure, thereby significantly improving the dyeing efficiency of dyeing with natural plant extracts; in addition, by performing irradiation treatment for a predetermined time with a light source containing a light wave with a wavelength that meets a predetermined wavelength range, the utility model can provide irradiation treatment in a controllable and stable manner, thereby avoiding the problem of instability and unevenness of the dyeing effect caused by weather reasons and differences in tiling positions, and significantly improving the stability and uniformity of the dyeing effect. Therefore, the utility model can not only significantly improve the stability and uniformity of the dyeing effect of dyeing with a dye containing a natural plant extract, but also significantly improve the dyeing efficiency.

[0035] Figure 1 Schematic diagram of a coloring device according to some embodiments of the present utility model is shown. Figure 1 As shown, the coloring device 100 includes: a dipping unit 110 and a light source irradiation area 120. The dipping unit 110 contains a dipping treatment liquid (the dipping treatment liquid contains a natural plant extract), and the dipping unit 110 is used to perform an infiltration treatment on the target fabric of the dipping treatment liquid input to the dipping unit 110. The light source irradiation area 120 is used to perform an irradiation treatment on the target fabric input to the light source irradiation area and treated by the dipping treatment liquid, so that the color of the target fabric changes. In some embodiments, the coloring device 100 also includes a control unit 160.

[0036] Regarding the dip coating unit 110, it includes, for example, a receiving chamber for receiving the dip coating treatment liquid. In some embodiments, the receiving chamber is configured to have a cubic shape, or a hexahedron with an inverted trapezoidal cross section. In some embodiments, the dip coating unit 110 is further provided with a temperature detection unit, a liquid level detection unit, a concentration detection unit or a sugar content detection unit, a heating unit, a liquid outlet, and a liquid inlet.

[0037] As for the liquid inlet, it is used to add the dip coating treatment liquid into the containing cavity.

[0038] As for the liquid outlet, it is used to discharge the dip coating treatment liquid in the accommodation chamber so as to lower the liquid level of the dip coating treatment liquid.

[0039] The temperature detection unit is used to collect temperature data of the dipping treatment liquid. The liquid level detection unit is used to collect liquid level data of the dipping treatment liquid. The concentration detection unit or the sugar content detection unit is used to collect concentration or sugar content data of the dipping treatment liquid respectively.

[0040] In some embodiments, the coloring device 100 further includes a dipping guide roller, and the dipping guide roller 112 is disposed below the liquid level of the dipping treatment liquid contained in the dipping unit 110, and is used to completely immerse the target fabric input into the dipping unit 110 below the liquid level of the dipping treatment liquid. Regarding the light source irradiation area 120, it includes, for example, one or more boxes 124 and a light source disposed inside the box. For example, each box includes a cavity 126 and one or more groups of light sources 122 disposed in the cavity.

[0041] The box 124 is used to confine the light emitted by the light source into a cavity 126 surrounded by the shell, and to provide a space for the target fabric 102 to be transmitted in the irradiation area of ​​the light source.

[0042] In some embodiments, one or more in-box guide devices are provided inside each box, and the guide devices are configured so that the transmission path of the target fabric in the box includes one or more rotating cloth running sections, and the light source is arranged in the space surrounded by the rotating cloth running sections so that one side of the target fabric transmitted in the rotating cloth running sections is illuminated by the light source.

[0043] The guide device in the box is, for example, a guide roller 128 inside the box. For example, the transmission path of the target fabric in the box is guided to a rotary cloth running section by one or more guide rollers inside the box. It should be understood that the distance between the rotary cloth running section and the light source is configured to be associated with the flatness of the target fabric in the irradiation area of ​​the input light source. For example, if the flatness of the target fabric is higher, the distance between the rotary cloth running section and the light source can be closer, thereby further improving the efficiency of the irradiation treatment. If the flatness of the target fabric is low, if the rotary cloth running section is too close to the light source, uneven irradiation will result, which will lead to uneven color change of the target fabric. In some embodiments, the rotary cloth running section includes, for example, any of the following: multiple sections with different transmission directions, arc-shaped cloth running sections, U-shaped cloth running sections, etc. In some embodiments, the rotary cloth running section is, for example, a U-shaped cloth running section. The transmission path of the target fabric in each box includes at least one or more U-shaped cloth running sections. Each box is provided with one or more groups of the light sources, and each U-shaped cloth running section includes a first section 129-1 and a second section 129-2 which are parallel to each other. A group of light sources is arranged between the first section 129-1 and the second section 129-2 of each U-shaped cloth running section, so that the first surface of the target fabric is irradiated by the same group of light sources when the target fabric passes through the first section 129-1 and the second section 129-2. Accordingly, the transmission mode of the target fabric in the box includes: passing through the first section along the first transmission direction, and passing through the second section along the second transmission direction, wherein the first section is parallel to the second section, and the same group of light sources is arranged between the first section and the second section, so that the first surface of the target fabric is irradiated by the same group of light sources when the target fabric passes through the first section and the second section. It should be understood that by irradiating the target fabric with both sides of the same group of light sources at the same time, the utilization rate of the light sources can be significantly improved, and the time required for the color change of the target fabric can be shortened.

[0044] In some embodiments, the light source irradiation area includes a plurality of boxes. The coloring device may further include a target fabric adjustment area disposed between adjacent boxes in the plurality of boxes, the target fabric adjustment area being configured so that the target fabric can be centered or flattened in the transmission path between the adjacent boxes. Figure 1 As shown, Figure 1 The light source irradiation area 120 in the embodiment includes two boxes 124. A target fabric adjustment area (e.g., Figure 4 In some embodiments, one or more guide rollers 128 disposed in the cavity 126 of each box 124 are used to guide the target fabric moving in the first transport direction in the box 124 to move in the second transport direction. The first transport direction and the second transport direction are opposite. For example, Figure 1As shown, the first transmission direction is the uplink direction, and the second transmission direction is the downlink direction.

[0045] In other embodiments, the light source irradiation area includes a box. Figure 2 Schematic diagram of a coloring device 200 according to some other embodiments of the present utility model is shown.

The plurality of box internal guide rollers, for example, include a plurality of first box internal guide rollers 128-1 located above the cavity 126 and a plurality of second box internal guide rollers 128-2 located below the cavity. The first box internal guide roller 128-1 is used, for example, to guide the target fabric moving in the first transmission direction in the box to move in the second transmission direction. The second box internal guide roller 128-2 is used, for example, to guide the target fabric moving in the second transmission direction in the box to move in the first transmission direction.

[0046] Regarding the guide roller inside the box, it is arranged inside the box to change the transmission direction of the target fabric in the box. In some embodiments, the guide roller inside the box can also be arranged above the box. In some embodiments, the target fabric moving in the first transmission direction in the box 124 is guided by the guide roller inside the box to move in the second transmission direction. Among them, the first transmission direction and the second transmission direction are opposite. In some embodiments, the first transmission direction is, for example, one direction horizontally to the left or horizontally to the right, and the second transmission direction is another direction horizontally to the left or horizontally to the right. In some embodiments, the first transmission direction is one direction of the upward or downward movement, and the second transmission direction is another direction of the upward or downward movement. It should be understood that making the first transmission direction of the transmission direction of the target fabric one direction of the upward or downward movement is conducive to maintaining better flatness of the target fabric during the cloth running and being irradiated by the light source.

The radiation amount of light waves with wavelengths that meet the predetermined wavelength range accounts for at least 10% of the total radiation amount of the light source. In other embodiments, the predetermined wavelength range is a wavelength less than or equal to 400nm. The radiation amount of light waves with wavelengths that meet the predetermined wavelength range accounts for more than 50% of the total radiation amount of the light source. In some embodiments, the predetermined wavelength range is less than or equal to 200nm.

[0072] Regarding the method of inputting the target fabric that has been treated by the dipping treatment liquid into the light source irradiation area, for example, it includes: inputting the target fabric that has been treated by the dipping treatment liquid into the light source irradiation area in a first transmission direction via a box input guide roller 121. The first transmission direction input is, for example, but not limited to, an upward direction, which is parallel to the light source. Regarding the box input guide roller 121, it is, for example, configured at the box input side below the box.

[0073] Regarding the method for irradiating the target fabric with the light source set in the light source irradiation area for a predetermined time, it includes, for example: allowing the target fabric to be input into the box and pass through the first section along the first transmission direction, and pass through the second section along the second transmission direction, so that when the target fabric passes through the first section and the second section, the first side of the target fabric is irradiated by the same group of light sources, the first transmission direction and the second transmission direction are opposite, and the same group of light sources is arranged between the first section and the second section. It should be understood that by arranging the same group of light sources between the first section and the second section, both sides of the same group of light sources can irradiate the first side of the fabric target fabric at the same time, which is conducive to significantly improving the utilization rate of the light source and reducing energy consumption. In addition, the characteristics of Xiangyunsha having a dark color on one side and a light color on the other side can also be achieved.

[0074] As for the light source, it is, for example, a group of light sources consisting of multiple rows of tubular light sources parallel to each other, wherein each row of the multiple rows of tubular light sources extends, for example, in a horizontal direction. Figure 3 The ends of multiple rows of tubular light sources parallel to each other are schematically illustrated in FIG. In addition, the spacing between adjacent rows of tubular light sources in the multiple rows of tubular light sources is configured, for example, so that the amount of radiation irradiated on the target fabric is uniform. In addition, the distance between the first section and the second section and the light source is associated with the flatness of the target fabric. For example, the distance between the first section and the second section and the light source is, for example, 4 to 5 centimeters.

[0075] At step 506, the target fabric with its color changed is output from the light source irradiation area.

[0076] For example, the target fabric irradiated by the light source (e.g., the target fabric leaving the second section) is guided to the target fabric adjustment area via the box output guide roller 127 so as to transfer the target fabric to the box input guide roller 121 of the next box, as shown in FIG. Figure 1 In some embodiments, the target fabric irradiated by the light source is guided to the drying device via the box output guide roller 127, such as Figure 2 as shown, or for example Figure 1 Or indicated by the box output guide roller 127 of the second box in 3.

[0077] In the above scheme, by inputting the target fabric into the dipping unit at the coloring device, so that the target fabric is wetted by the dipping treatment liquid (containing natural plant extract) contained in the dipping unit; and inputting the target fabric after the wet treatment into the light source irradiation area, and irradiating the target fabric for a predetermined time by a light source including a light wave with a wavelength that meets the predetermined wavelength range, so that the color of the target fabric changes, and then outputting the target fabric with the changed color from the light source irradiation area, the utility model can automatically complete the wet treatment and irradiation treatment of the target fabric without manual immersion, tiling and sun exposure, thereby significantly improving the dyeing efficiency of dyeing with natural plant extract; in addition, by irradiating the target fabric with a light wave with a wavelength that meets the predetermined wavelength range for a predetermined time, the utility model can provide the irradiation treatment in a controllable and stable manner, thereby avoiding the problem of instability and unevenness of the dyeing effect caused by weather reasons and differences in tiling positions, and significantly improving the stability and uniformity of the dyeing effect. Therefore, the utility model can not only significantly improve the stability and uniformity of the dyeing effect of dyeing with a dye containing a natural plant extract, but also significantly improve the dyeing efficiency. Furthermore, since the utility model uses light waves with wavelengths in a predetermined wavelength range and light for a predetermined time to control the color change of the target fabric treated by natural plant extract, the utility model can significantly improve the coloring effect and color fastness of the target fabric, and make the color change controllable. For example, in terms of color fastness, the utility model can improve by at least 0.5 level compared with the traditional method.

[0078] Test data show that, taking Xiangyun yarn as an example, the traditional method of manual dyeing, flat laying and sun drying takes up a large area of ​​drying field, and each acre of land produces about 100 meters of target products per day. In the same area, multiple coloring equipment (for example, 24-hour operation) using the coloring method of the utility model can be configured, and the daily output can reach 50 times the daily output of the traditional method. Therefore, the utility model can not only significantly increase the output, but also help save land. In addition, the target fabric obtained by the dyeing effect of the utility model has a clean and flat surface, the depth of the base color can be controlled and adjusted, and the finished fabric has a stronger adaptability to subsequent processing, printing and dyeing.

[0079] In some embodiments, method 500 further includes: subjecting the target fabric in the output light source irradiation area to multiple rounds of infiltration treatment and irradiation treatment through the current coloring device, or the next or subsequent multiple coloring devices where the light source irradiation area is located, until the target fabric after the current round of irradiation treatment meets the predetermined attribute condition. Regarding the target fabric meeting the predetermined attribute condition, it is, for example, to make the target fabric meet the predetermined attribute condition about the attribute characteristics of Xiangyunsha. For example, the color of the target fabric is the target color of Xiangyunsha.

[0080] In some embodiments, Figure 3 As shown, the target fabric 102 of the light source irradiation area 120 of the output coloring device 300 is subjected to multiple rounds (for example, N rounds, N is a natural number greater than or equal to 2) of wetting treatment and irradiation treatment (or multiple rounds of wetting treatment, irradiation treatment and drying treatment) by the current coloring device 300 until the target fabric 102 subjected to the irradiation treatment by the current round (for example, the Nth round) of the coloring device 300 satisfies the predetermined attribute conditions regarding the attribute characteristics of Xiangyunsha.

[0081] In some embodiments, Figure 6 As shown, the coloring system includes a plurality of coloring devices arranged in sequence, for example, the first coloring device 600-1 to the Nth coloring device 600-N. Each of the plurality of coloring devices is, for example, the coloring device mentioned above. These plurality of coloring devices arranged in sequence are used to perform multiple rounds of coloring treatment on the target fabric, for example, the target fabric subjected to the corresponding round of coloring treatment by the previous coloring device in the adjacent coloring device is provided to the previous coloring device in the adjacent coloring device for the next round of coloring treatment, and each round of treatment in the multiple rounds of coloring treatment at least includes an infiltration treatment by the dipping treatment liquid and an irradiation treatment by the light source irradiation area. In some embodiments, each round of treatment in the multiple rounds of coloring treatment also includes a drying treatment. In some embodiments, the target fabric 102 outputting the light source irradiation area of ​​the first coloring device 600-1 is subjected to multiple rounds of infiltration treatment and irradiation treatment (or multiple rounds of infiltration treatment, irradiation treatment and drying treatment) by the next coloring device or the subsequent coloring devices until the target fabric irradiated by the coloring device (for example, the Nth coloring device 600-N) in the current round (for example, the Nth round) satisfies the predetermined attribute conditions of Xiangyun yarn. It should be understood that by adopting the above-mentioned means, the utility model can utilize the same coloring device or multiple coloring devices in succession to cycle through multiple rounds of infiltration treatment and irradiation treatment (or multiple rounds of infiltration treatment, irradiation treatment and drying treatment), thereby significantly improving the efficiency and degree of automation in manufacturing Xiangyunsha.

[0087] In some embodiments, Figure 3 As shown, the target fabric 102 after being dried by the drying unit 130 of the coloring device 300 is provided to the dipping unit 110 of the current coloring device 300 where the drying unit 300 is located, so as to undergo the next round of dipping treatment by the current coloring device 300.
