[0035] In addition, if there are terms such as "first" and "second", these terms are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present application, if there is a term "plurality", the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0037] In the present application, unless otherwise clearly specified and limited, if there is a description such as a first feature being "on" or "under" a second feature, the meaning may be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium.

[0039] The following will further elaborate on the embodiments of this application with reference to the Figures 1-5 accompanying drawings.

[0040] Figure 1 FIG. shows a schematic structural diagram of a liquid transfer direction detection device in an embodiment of this application. Referring to Figure 1 FIG., a liquid transfer direction detection device provided in an embodiment of this application includes: a liquid supply pipeline for transporting a conductive liquid to a fabric to be tested; a detection unit for contacting the fabric to be tested, the detection unit includes a plurality of detection areas, the detection areas are sectors centered on the center of the detection unit, and the detection areas are insulated from each other; a control unit (not shown in the figure), connected to each detection area, for collecting detection signals corresponding to each detection area and determining the liquid transfer direction corresponding to the fabric to be tested based on the detection signals.

[0041] Among them, the liquid supply pipeline is arranged above the fabric to be tested, and the conductive liquid is dripped onto the fabric to be tested. The conductive liquid diffuses on the fabric to be tested, and the fabric to be tested containing the conductive liquid becomes a conductor and conducts within the diffusion range; in the detection unit, the detection areas in contact with the fabric to be tested within the diffusion range of the conductive liquid form a conductive loop, and the control unit can collect the corresponding detection signals; the detection areas in contact with the fabric to be tested outside the diffusion range of the conductive liquid cannot form a conductive loop, and the detection signals collected by the control unit are 0 values. In this way, the control unit can determine the conductive detection areas according to the detection signals, and thus determine the transfer direction of the conductive liquid in the fabric to be tested according to the direction corresponding to the detection areas.

[0042] Exemplarily, the conductive liquid can be liquid water, and the liquid water can be a sodium chloride solution with a concentration of 9 g / L, and the solution conductivity is (16.0 ± 0.2) mS at 25 °C. The conductive liquid transported by the liquid supply pipeline to the fabric to be tested during each detection process is (0.22 ± 0.01) g. Another example is that the conductive liquid can also be a sodium chloride solution with other solution concentrations or other doped ionic liquids.

[0043] In one possible implementation, the position where the conductive liquid drips onto the fabric to be tested can be set as the center of the detection unit. In another possible implementation, the conductive liquid can be transmitted to any position of the fabric to be tested, the mapping relationship between the transmission position of the conductive liquid and the detection position of the detection unit is obtained, and the transfer direction of the conductive liquid is determined according to the mapping relationship.

[0044] The above liquid transfer direction detection device includes: a liquid supply pipeline for transmitting the conductive liquid to the fabric to be tested; a detection unit for contacting the fabric to be tested, the detection unit includes a plurality of detection areas, the detection areas are sectors centered on the center of the detection unit, and the detection areas are insulated from each other; a control unit connected to each detection area for collecting the detection signals corresponding to each detection area and determining the liquid transfer direction corresponding to the fabric to be tested based on the detection signals. In this embodiment, by detecting multiple possible conductive liquid diffusion directions of the fabric to be tested through multiple detection areas, the transfer direction of the conductive liquid in the fabric to be tested can be accurately and reliably determined, so as to better evaluate the liquid conduction performance of the fabric to be tested and improve the production efficiency of textile fabrics.

[0045] Figure 2 The structural schematic diagram of the first detection part in an embodiment of the present application is shown. Refer to Figure 1 and Figure 2 In an embodiment of the present application, the detection unit in the liquid transfer direction detection device includes: a first detection part and a second detection part, the first detection part and the second detection part are arranged opposite to each other; the first detection part includes a plurality of first detection areas, and each first detection area is used to contact the first surface of the fabric to be tested; the second detection part includes a plurality of second detection areas, and each second detection area is used to contact the second surface of the fabric to be tested, and the first surface and the second surface face away from each other.

[0046] Among them, the first detection area is a sector centered on the center of the first detection part; the second detection area is a sector centered on the center of the second detection part.

[0047] In one possible implementation, the first detection part includes a substrate, and the center of the substrate is the center of each first detection area. Exemplarily, Figure 2 the substrate shown in includes a connecting part and a mounting part, the mounting part is a rounded rectangle, and the connecting part is a rectangular part connected to the narrow side of the mounting part. The center of the first detection part is the center of the mounting part, that is, the intersection of the midpoint connection line of the long sides of the mounting part and the midpoint connection line of the narrow sides is the center of each first detection area.

[0048] Among them, the fabric to be tested can be applied to textiles in different functional scenarios, and different materials or treatment methods may be used on the front and back sides, resulting in different liquid transfer performances on both sides. Exemplarily, for the fabric to be tested used in outdoor clothing, the outer layer may have a waterproof coating, while the inner layer has a moisture absorption and sweat discharge function.

[0049] In this embodiment, the first detection unit is used to detect the transfer direction of the conductive liquid on the first side of the fabric to be tested, and the second detection unit is used to detect the transfer direction of the conductive liquid on the second side of the fabric to be tested, so as to detect the liquid transfer directions of the conductive liquid on the first side and the second side of the fabric to be tested that face away from each other, and evaluate the performance of the fabric to be tested in the corresponding application scenario. For the fabric to be tested that requires material uniformity, by detecting the liquid transfer directions of the first side and the second side, it is determined whether there are defects such as non-uniformity in the fabric manufacturing process, ensuring product consistency and reliability.

[0050] Continue to refer to Figure 2 In the liquid transfer direction detection device provided in an embodiment of the present application, the included angle between the axes of two adjacent first detection regions is a uniform preset angle.

[0051] Exemplarily, the first detection unit may include 8 first detection regions, and the included angle between the axes of two adjacent first detection regions is 45°, and the axis is the angular bisector of the central angle of the first detection region. In the angle coordinate system as shown in Figure 2 , the axis angles of each first detection region are 0°, 45°, 90°, 135°, 180°, 225°, 270°, and 315° respectively.

[0052] Another exemplarily, the first detection unit may include 4 first detection regions, and the included angle between the axes of two adjacent first detection regions is 90°. Referring to the angle coordinate system shown in Figure 2 , the axis angles of each first detection region may be 0°, 90°, 180°, and 270° respectively.

[0053] In this embodiment, uniformly distributed first detection regions are arranged on the first detection unit. When the conductive liquid diffuses to a certain first detection region on the fabric to be tested, the control unit can collect the detection signal of this first detection region, so as to determine the corresponding liquid transfer direction of the fabric to be tested. The smaller the central angle of the first detection region in the first detection unit, the more the number of first detection regions, the more detailed the determined liquid transfer direction, but the corresponding resource consumption will also increase. Preferably, the first detection unit may be provided with 8 first detection regions, and the included angle between the axes of two adjacent first detection regions is 45°.

[0054] Figure 3 shows a schematic structural diagram of the first detection unit in another embodiment of the present application. Referring to Figure 2 and Figure 3 In the liquid transfer direction detection device provided in an embodiment of the present application, the first detection region includes: a plurality of first detection arcs, the first detection arc is an arc with the center of the first detection region as the center of the circle, and the radius of the first detection arc is less than or equal to the radius of the first detection region.

[0055] Among them, a plurality of first detection arcs and the boundary line of the first detection area form concentric circular arcs, and the first detection arcs are insulated from each other.

[0056] Exemplarily, as Figure 3 shown, a set of concentric circles is constructed with the center of the first detection part as the center of the circle, a total of 13, numbered 0 to 12. The first detection arc is the arc where the first detection area intersects the concentric circles with odd numbers. That is, as Figure 3 shown in the first detection area, there are 6 first detection arcs, which are respectively the arcs where the first detection area intersects the circles numbered 1, 3, 5, 7, 9, and 11.

[0057] In a possible implementation manner, as Figure 3 shown, the diameters of the circles numbered 0 to 12 are 3.5, 8.5, 13.5, 18, 22.5, 27, 31.5, 36, 40.5, 45, 49.5, 54, and 58.5 respectively, with the unit of millimeters (mm). The value range of the radius of the first detection area can be greater than or equal to 58.5 mm.

[0058] In a possible implementation manner, the radii corresponding to the plurality of first detection arcs form an arithmetic sequence.

[0059] In a possible implementation manner, the first detection arc includes: a plurality of detection probes, and the plurality of detection probes are evenly distributed around the axis of the first detection area.

[0060] Among them, as Figure 2 and Figure 3 shown, a dot in the figure represents a detection probe, and the number of probes on each first detection arc is 1 to 3. Exemplarily, if the number of probes on the first detection arc is 1, the probe is set at the midpoint of the first detection arc, that is, the intersection point of the first detection arc and the axis of its corresponding first detection area; if the number of probes on the first detection arc is 2, the probes are set on both sides of the midpoint of the first detection arc, and the distance of each probe from the midpoint of the first detection arc is equal; if the number of probes on the first detection arc is 3, one of the probes is set at the midpoint of the first detection arc, and the other two probes are set on both sides of the midpoint of the first detection arc, and the distance between adjacent two probes is equal. Exemplarily, the diameter of the probe can be 1.54 mm or 1.2 mm.

[0061] In a possible implementation manner, the structure of the second detection part is exactly the same as that of the first detection part.

[0062] In a possible implementation, the first detection unit is disposed above the fabric to be tested, and the second detection unit is disposed below the fabric to be tested. The second detection area includes a plurality of second detection arcs, and each second detection arc includes a plurality of detection probes. The positions of the detection probes in the second detection unit are the same as those of the detection probes in the first detection unit. The diameter of the detection probes in the second detection arc is smaller than that of the detection probes in the first detection arc. Exemplarily, the diameter of the detection probes in the first detection arc can be 1.54 mm, and the diameter of the detection probes in the second detection arc can be 1.2 mm.

[0063] In a possible implementation, referring to the foregoing embodiments, the first detection unit includes 8 first detection areas, and the angle between the axes of two adjacent first detection areas is 45°; there are 6 first detection arcs in each first detection area, which are the arcs where the first detection area intersects with the circles numbered 1, 3, 5, 7, 9, and 11. The concentric circle numbers are used as the numbers of the first detection arcs, and the number of probes on each first detection arc is shown in Table 1.

[0064] Table 1 Number of probes on each first detection arc in each first detection area

[0065]

[0066] Among them, 13 probes are arranged in each first detection area, for a total of 104 probes.

[0067] In a possible implementation, the multiple detection probes in the first detection arc are connected in series.

[0068] Among them, in combination with the foregoing embodiments, the first detection unit includes a substrate, and the center of the substrate is the center of each first detection area. The substrate can be a PCB board (Printed Circuit Board), and the detection probes are fixedly arranged on the substrate. The multiple detection probes in each first detection arc are connected in series. When one of the detection probes is conducted with the control unit, all the probes in this first detection arc are conducted with the control unit. Exemplarily, the detection probes can be fixed on the substrate by welding.

[0069] In a possible implementation, the first detection unit further includes a connection socket, which is fixedly arranged on the substrate. One end of the connection socket is electrically connected to the control unit, and the other end of the connection socket is electrically connected to each first detection arc through the substrate. Exemplarily, the connection socket can be fixedly arranged at the connection part of the substrate.

[0070] In a possible implementation, the test display window of the control unit is as Figure 4 shown. The control unit collects the detection signals of each first detection arc in each first detection area, obtains the detection data of each first detection area, and generates as according to the detection dataFigure 4 The transfer radar chart shown. Among them, Sample represents the name of the fabric to be tested; Side represents the test surface of the fabric to be tested, and the test surface includes a first surface and a second surface. The first surface can be Top, and the second surface can be Bottom. That is, when the fabric to be tested is placed horizontally, the first detection part contacts the top surface of the fabric to be tested, and the second detection part contacts the bottom surface of the fabric to be tested; 1[0’] in the Top row represents the first first detection area, and the axis angle of the first first detection area is 0°; 2[45’] represents the second first detection area, and the axis angle of the second first detection area is 45°, and so on; Roundness is the roundness of the diffusion area of the conductive liquid in the fabric to be tested calculated according to the detection data of each first detection area. The roundness value ranges from [0,1]. The closer it is to 0, the more irregular or slender the diffusion area shape is, and the closer it is to 1, the closer the diffusion area is to a standard circle; Area is the area of the diffusion area calculated according to the detection data.

[0071] In a possible implementation manner, the control unit is further configured to time and calculate the transfer speed of the conductive liquid in the fabric to be tested: The control unit starts timing from the moment when the conductive liquid drips onto the fabric to be tested, and uses the conduction conditions of each detection area to collect the detection signals corresponding to each detection area within a preset time interval to obtain the detection data of each detection area, so as to determine the transfer speed of the conductive liquid in each transfer direction on the fabric to be tested.

[0072] In this embodiment, a plurality of first detection arcs with different radii are arranged in the first detection area. In this way, if the probe in the first detection arc is within the diffusion range of the conductive liquid, the probe and the control unit form a conduction loop, and the control unit can collect the detection signal corresponding to the first detection arc; if the probe of the first detection arc is not within the diffusion range of the conductive liquid, the probe and the control unit cannot conduct, and the detection signal corresponding to the first detection arc collected by the control unit is a 0 value; the control unit can determine the transfer direction of the conductive liquid on the fabric to be tested according to the collected detection signal, and further determine the transfer distance in the transfer direction according to the radius of the conductive first detection arc, improving the detection accuracy of the liquid transfer direction detection device.

[0073] Continue to refer to Figure 2 and Figure 3 , in a liquid transfer direction detection device provided in an embodiment of the present application, the first detection part further includes: induction probes, which are arranged in a concentric circle distribution, and the concentric circles formed by the induction probes are concentric with each first detection area.

[0074] In a possible implementation manner, in combination with the foregoing embodiments, a set of 13 concentric circles are constructed with the center of the first detection part as the center of the circle, numbered from 0 to 12. The induction probes are evenly arranged on the concentric circles with even numbers, that is, on 7 circles numbered 0, 2, 4, 6, 8, 10, and 12. The induction probes on each circle are connected in series.

[0075] In a possible implementation manner, the number of probes arranged on 13 concentric circles numbered from 0 to 12 are 4, 8, 17, 16, 28, 16, 39, 16, 50, 24, 60, 24, and 72 respectively.

[0076] In this embodiment, when the induction probe is within the diffusion range of the conductive liquid on the fabric to be measured, the induction probe is conducted with the control unit, and the control unit can collect the detection signal corresponding to the induction probe, and then determine the position radius corresponding to the induction probe, and estimate the transfer area of the conductive liquid on the fabric to be measured.

[0077] Refer to Figures 1 to 4 , a liquid transfer direction detection device provided in an embodiment of the present application includes: a liquid supply pipeline for transporting a conductive liquid to the fabric to be measured; a detection unit for contacting the fabric to be measured. The detection unit includes a plurality of detection regions, and the detection regions are sectors with the center of the detection unit as the center of the circle. Each detection region is insulated from each other. The detection unit includes: a first detection part and a second detection part, and the first detection part and the second detection part are arranged opposite to each other; the first detection part includes a plurality of first detection regions, a substrate, and induction probes. Each first detection region is used to contact the first surface of the fabric to be measured; the second detection part includes a plurality of second detection regions, and each second detection region is used to contact the second surface of the fabric to be measured. The first surface and the second surface face away from each other; a control unit is connected to each detection region for collecting the detection signal corresponding to each detection region and determining the liquid transfer direction corresponding to the fabric to be measured based on the detection signal.

[0078] Wherein, the angle between the axes of two adjacent first detection regions is a uniform preset angle.

[0079] Wherein, the first detection region includes: a plurality of first detection arcs, and the first detection arc is an arc with the center of the first detection region as the center of the circle. The radius of the first detection arc is less than or equal to the radius of the first detection region.

[0080] Wherein, the first detection arc includes: a plurality of detection probes, and the plurality of detection probes are evenly distributed around the axis of the first detection region; the plurality of detection probes in the first detection arc are connected in series.

[0081] Wherein, the center of the substrate is the center of each first detection region; a plurality of detection probes are fixedly arranged on the substrate.

[0083] Figure 5 The flowchart of the liquid transfer direction detection method in an embodiment of the present application is shown, which is applied to the liquid transfer direction detection device in the above embodiment. The method includes:

[0084] Step 502, use the liquid supply pipeline to transport the conductive liquid to the fabric to be tested.

[0085] Step 504, collect the detection signals corresponding to each detection area.

[0086] In a possible implementation manner, the liquid transfer direction detection device uses a cyclic acquisition method to collect each detection area, that is, only one detection area is sent a collection signal at the same moment. If a detection signal can be received at this moment, it means that there is a probe conduction in this detection area. If the detection signal is 0, it means that there is no conduction loop in this detection area.

[0087] In this step, the cyclic acquisition method is used to collect the detection signals, which can effectively avoid the mutual influence between the first detection part and the second detection part, thereby ensuring the reliability and accuracy of the liquid transfer direction detection method.

[0088] Step 506, determine the liquid transfer direction corresponding to the fabric to be tested based on the detection signals.

[0089] In a possible implementation manner, the detection signal is a voltage signal; if the detection signal is greater than a preset threshold, the detection area corresponding to the detection signal is determined as the liquid transfer direction corresponding to the fabric to be tested. Exemplarily, the preset threshold can be 0. When the detection signal is greater than 0, it means that the probe in this detection area is conducted due to the diffusion of the conductive liquid; according to the detection signal and the preset detection area information, the liquid transfer direction can be determined, and the liquid transfer distance and the liquid transfer speed can also be determined.

[0090] The technical features of the above embodiments can be combined arbitrarily. For the sake of brief description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0091] The above embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it cannot be understood as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application.
