[0002] The liquid wicking performance of textiles is an important indicator of the hygroscopic performance of textiles. It affects the coloring and finishing efficiency of textiles, and also affects the wearing comfort of textiles after being made into products. The vertical wicking method is an important method for testing the moisture conductivity of fabrics. The principle is to place the sample vertically and immerse the bottom of the sample in water. At this time, the sample will wick the water upward. The liquid wicking performance of textiles can be judged by measuring the wicking length of the sample within a given time or the time required for the sample to wick a given distance. However, when the samples in the prior art are tested for vertical wicking performance, most of them are observed manually, resulting in the problem of easy judgment errors when testing the sample wicking performance.

[0035] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0036] Please refer to Figures 1 to 4 As shown, in an embodiment of the present invention, a textile wicking test device is provided for vertical wicking test of textiles, and the textile wicking test device comprises:

[0037] A workbench 1, a detection container 2, a sample clamping frame 3, a sample detection component 4 and a lifting mechanism 5. The detection container 2 is arranged on the workbench 1, and is used to contain liquid. The sample clamping frame 3 is arranged on the workbench 1, and is used to clamp the sample so that the sample is suspended above the detection container 2, and one end of the sample extends into the detection container 2 to contact the liquid. The sample detection component 4 is located on one side of the sample clamping frame 3, and the sample detection component 4 has a transmitting part and a detecting part, the transmitting part is used to transmit a detection signal to the sample, and the detecting part is used to receive the detection signal reflected by the sample and detect the intensity of the above detection signal. The lifting mechanism 5 is arranged on the workbench 1, and the driving end of the lifting mechanism 5 is connected to the sample detection component 4, and is used to drive the sample detection component 4 to rise and fall relative to the workbench 1.

[0038] The workbench 1 refers to a support member with a certain area on the top, and the shape of the workbench 1 is not limited here. The detection container 2 refers to a member that can hold water or other liquids, and an opening can be provided on the top of the detection container 2 to facilitate the end of the sample to enter the detection container 2 from the top of the detection container 2.

[0039] The sample detection component 4 is a component that can transmit a detection signal to the sample and detect the detection signal reflected by the sample. At least a part of the sample detection component 4 is an electrical component, so that the sample detection component 4 can send the detected signal to the control unit 6 or the computer.

[0040] The working principle of the fabric wicking test device in this embodiment is as follows:

[0041] When testing textiles, one end of the sample is fixed above the test container 2 through the sample clamping frame 3, and the other end of the sample is extended into the test container 2 and contacts the liquid in the test container 2. The test signal is transmitted to the sample by the transmitting part on the sample detection component 4, and the intensity of the test signal reflected at a preset point on the sample is detected by the detection part. The wicking performance of the sample can be measured by utilizing the property change of the sample before and after being soaked in the liquid, which causes the intensity of the test signal reflected before and after the sample is soaked to change. The sample detection component 4 can be stopped at a preset height by the lifting mechanism 5, and a preset point on the sample is continuously measured. When the detection part detects that the test signal reflected at this point changes significantly, the measurement time is recorded, and the time required for the sample to wick to the preset height can be obtained. Alternatively, after the end of the sample has been immersed in the liquid for a preset time, the lifting mechanism 5 can be used to drive the sample detection component 4 to scan the sample at a uniform speed. At this time, the intensity of the detection signal reflected by the sample detected by the detection unit will have an obvious change in the positions where the sample is immersed and not immersed. By recording the height position of the lifting mechanism 5 when the intensity of the detection signal changes significantly, the vertical wicking distance of the sample within the preset time can be obtained.

[0042] The textile wicking test device provided by the present invention utilizes the property change of the sample before and after being infiltrated by liquid, which causes the detection signal intensity reflected by the sample before and after being infiltrated to change. The detection unit detects the detection signal intensity reflected by the preset point on the sample to measure the wicking performance of the sample. At the same time, the height position of the sample detection component 4 is adjusted by the lifting mechanism 5. Compared with the method of using manual timing and observing the sample at the same time in the prior art, the sample detection component 4 is used to cooperate with the lifting mechanism 5 to perform automatic detection and record the results, which can reduce the consumption of labor costs, and can also avoid the judgment errors caused by manual detection to a certain extent, and improve the accuracy of detection.

[0043] It should be noted that, in order to facilitate the use of the textile wicking test device, a computer for recording and analyzing data, a control unit 6 for controlling the movement of the action parts in the device, and a power supply unit can also be provided on the workbench 1. Of course, the functions of recording and analyzing data and controlling the movement of the action parts in the device can also be achieved by a computer at the same time. The power supply unit can be powered by an external power supply or by a battery. The above features are all conventional settings of automated equipment, so they will not be repeated here.

[0044] In an optional embodiment, a protective cover (not shown) is further provided on the workbench 1, and the detection container 2, the sample detection assembly 4 and the sample holder 3 can all be provided inside the protective cover.

Specifically, the light emitting unit 41 refers to a component that can emit light in a preset direction, and realizes luminescence by converting electrical energy into light energy. The light intensity detection unit 42 refers to an electrical component that can convert light energy into an electrical signal, such as a photosensitive component. The light intensity detection unit 42 can also change the intensity of the electric signal emitted by itself when the intensity of the light reflected by the sample changes, and the purpose of sending an electric signal to the computer or control unit 6 is achieved by the cooperation of the light intensity detection unit 42 and the detection circuit. The light emitting unit 41 can emit light to illuminate a point area or an end area on the sample. At the same time, the intensity of the light reflected by the sample before and after the wicking infiltration will change. At this time, the light intensity detection unit 42 is used to detect the intensity of the light reflected on the sample to realize the detection of the sample wicking position, which can make the detection more accurate.

Specifically, a light emitting diode is a commonly used light emitting device that emits light by releasing energy through the recombination of electrons and holes. A light emitting diode can efficiently convert electrical energy into light energy, and the light emitting unit 41 using a light emitting diode can save more energy. A photodiode, also called a photosensitive diode (photodiode), is a light detector that can convert light into a current or voltage signal according to the mode of use. The tube core often uses a PN junction (PN junction) with a photosensitive feature, which is very sensitive to changes in light, has unidirectional conductivity, and changes electrical characteristics when the light intensity is different. Therefore, the intensity of light can be used to change the current in the circuit.

[0065] The transmitting part in the sample detection component 4 transmits the detection light to the sample, and the control unit 6 obtains the light intensity at the preset point on the sample according to the preset frequency through the detection part in the sample detection component 4. When the light intensity at the preset point on the sample has an obvious step, the sample detection component 4 stops the detection and records the time;

[0066] The wicking rate of the sample is calculated according to the formula, which is:

[0072] The sample detection assembly 4 is moved to the highest point of the sample by the lifting mechanism 5, one end of the sample is fixed on the sample holder 3, and the other end of the sample is inserted into the liquid inside the detection container 2;

[0073] After the other end of the sample is inserted into the liquid for a preset time, the emitting unit emits detection light to the sample, and drives the sample detection assembly 4 to scan from the top of the sample to the liquid surface at a preset speed through the lifting mechanism 5. The control unit 6 controls the detection unit to obtain the light intensity at each position on the entire sample according to the preset frequency.

[0074] The wicking rate of the sample is calculated according to the formula, which is:

[0075] S=D2 / T2

[0076] Where S is the wicking rate of the sample, D2 is the height from the liquid surface where the light intensity step occurs on the sample, and T2 is the preset time for the other end of the sample to be inserted into the liquid;

[0077] Remove the sample from the sample holder 3 and repeat the above steps until the test is completed.
