Description

Technical Field

[0001] The invention belongs to the technical field of fabric pilling testing, and particularly relates to a fabric pilling testing device and an analysis method. Background Art

[0002] Textiles, an integral part of daily life, are constantly exposed to friction, stretching, twisting, and bending from contact with the skin and the surrounding environment. These effects, combined with prolonged and varying degrees of friction and stretching, can gradually lead to pilling, spandex exposure, fiber breakage, and bulging. These changes can severely impact the comfort and aesthetics of fabrics and garments. For example, prolonged friction between the armhole and side seam of a shirt can cause pilling in these areas, particularly on knitted fabrics, severely impacting the garment's appearance. Rigorous performance testing of these areas of textiles before use is essential. Therefore, a fabric pilling testing device and analysis method have been designed to assess the pilling susceptibility of textiles before use and assess their quality. Summary of the Invention

[0039] See also Figure 5 The pilling test and analysis system includes a data acquisition module, an analysis module and a processing module. The data acquisition module includes an image acquisition submodule 1, an image acquisition submodule 2 and an image acquisition submodule 3. The image acquisition submodule 1 is electrically connected to the first camera 15, and the image acquisition submodule 2 is electrically connected to the second camera 16.

[0040] The analysis module includes an area recognition submodule and a comparison submodule. The area recognition submodule is electrically connected to the first image acquisition submodule, and the comparison submodule is electrically connected to the second image acquisition submodule.

[0041] The processing module includes a prompting submodule and a marking submodule.

[0042] The pilling test analysis system includes the following steps:

[0043] Step 1: Wrap the textile around the winding rollers 3 on both sides of the top plate 1, start the motors 2 on both sides to drive the winding rollers 3 to rotate in opposite directions to straighten the textile;

[0044] Step 2: When the textile is straightened, the second camera 16 is used to capture the shape and position of the side of the textile, and transmits the signal to the comparison submodule;

[0045] Specifically, after the textile is installed, the side view of the straightened textile is transmitted to the second image acquisition submodule via the second camera 16 , and serves as a side reference for subsequent testing of the textile.

[0046] Step 3: Start the test component to detect whether the surface of the textile is prone to pilling, and then analyze the pilling area of the textile through the area recognition submodule.

[0047] Step 4: When testing whether there are hair balls on the surface of the textile, the second camera 16 is activated in real time to shoot the side of the textile, identify the deformation degree of the side of the textile, and judge the quality of the textile during deformation.

[0048] Step 5: Determine the overall quality of the textile based on the pilling area on the textile surface and the quality of the textile when deformed.

[0049] Step 3 includes the following specific steps:

[0050] Step 3-a: Start the cylinder 6 to extend, so that the friction strip 11 on the pressing plate 10 contacts the surface of the textile, and start the linear drive to drive the support frame 7 to move on the slide rail 13;

[0051] Step 3-b: When the support frame 7 moves, it drives the friction strip 11 on the pressure plate 10 to rub the textile. At this time, the first camera 15 captures the surface of the textile and transmits the signal to the image acquisition submodule 1;

[0052] Step 3-c: The image acquisition submodule repeatedly transmits the signal to the area recognition submodule to determine the pilling area of the textile;

[0053]

[0054] Step 4 includes the following specific steps:

[0055] Step 4-a: When the support frame 7 moves, it presses the textile downward, causing the textile to bend. The second camera 16 takes a photo of the bent textile and transmits it to the image acquisition sub-module 2;

[0056] Step 4-b: Using the comparison submodule, the previously captured reference image is compared with the currently captured side image to determine the degree of deformation of the textile under pressure.

[0057]

[0058] Step 4-c: When the textile is subjected to pressure from the pressing plate 10, the friction ball 14 comes into contact with the textile to further determine whether lines are drawn on the textile surface;

[0059] Specifically, since the friction strip 11 is made of a flexible material, when the friction strip 11 is subjected to force, the friction balls 14 inside will be exposed through the outlet 4 and contact the surface of the textile. When the surface burrs of the friction balls 14 hook out the lines of the textile, it indicates that a large gap is generated in the middle of the textile when the textile is deformed. When the surface burrs of the friction balls 14 do not hook out the lines of the textile, it indicates that no gap is generated in the middle of the textile when the textile is deformed.

[0060] Step 4-d: Determine the quality of the textile during deformation based on the degree of deformation and whether the yarn is hooked;

[0061] Specifically, when the deformation degree is relatively small, no lines are drawn, indicating that the quality of the textile when deformed is good. When lines are drawn, it means that the quality of the textile when deformed is poor, and a signal is transmitted to the prompt submodule, indicating that the product is unqualified.

[0062] Step 5 includes the following specific steps:

[0063] Step 5-a: If the pilling area of the textile is low and the quality of the textile when deformed is good, it means that the overall quality of the textile is good. The staff will remove the textile and place it in the placement slot 9;

[0064] Step 5-b: When the pilling area of the textile is low and the quality of the textile during deformation is poor, the signal is transmitted to the marking submodule, which marks it and the staff repairs the line;

[0065] Step 5-c: If the pilling area of the textile is high, a signal is transmitted to the prompt submodule, indicating that the product is unqualified.
