Description

Technical Field

[0001] This utility model relates to the technical field of fabric quality inspection, and in particular to a device for testing the color fastness to rubbing of polyester fabric. Background Technology

[0002] Color fastness to rubbing refers to the ability of textiles to resist color fading when subjected to friction, and it is one of the important indicators for measuring the quality of textiles. In the textile industry, this property directly affects the color stability of clothing, home furnishings, and other products during daily use (such as wearing, washing, and friction contact). Testing color fastness to rubbing typically involves simulating actual friction scenarios, using a specific device to rub the fabric repeatedly against a friction material (such as cotton pads or wool), observing the color change on the fabric surface and the degree of staining by the friction material. According to relevant regulations such as national standard GB / T 3920, the test is divided into two types: dry rubbing and wet rubbing. The former uses a dry rubbing cloth, and the latter uses a wet rubbing cloth. After rubbing, the color fastness grade is evaluated by comparing it with a standard staining grey card (grades 1-5, with grade 5 being the best). This indicator not only affects the durability of the product's appearance but also involves consumer health (such as the possibility of dye fading coming into contact with skin) and market competitiveness; therefore, it is a mandatory test item in the textile production and quality inspection process.

[0003] In the textile industry, polyester fabric is a commonly used material, and its color fastness to rubbing is an important indicator for evaluating product quality, requiring testing according to standards such as GB / T 3920. Existing testing devices have certain shortcomings in practical applications. For example, the pulling components are mostly unidirectional and single-unit, leading to uneven force on the fabric during friction, affecting testing efficiency and stability. Furthermore, color card holders are usually set up independently, requiring frequent sample movement for color comparison, increasing operational steps. Utility Model Content

The integrated design of the color card holder and the testing area simplifies the color comparison process. The overall structure is compact and practical, which can efficiently complete the testing of the color fastness to rubbing of polyester fabric, improve the convenience of the testing operation and the intuitiveness of the result comparison, and meet the actual application needs of quality testing in the textile industry.

[0006] To achieve the above objectives, this utility model proposes a device for testing the color fastness to rubbing of polyester fabric, comprising: a base; two sets of pulling components symmetrically mounted on the base; a friction component disposed on the base; a color card holder fixed on the base; and a driving mechanism connected to the pulling components.

[0020] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0021] The following description, in conjunction with the accompanying drawings, describes the polyester fabric rubbing color fastness testing device according to an embodiment of the present invention.

[0022] like Figures 1-4 As shown, the polyester fabric rubbing color fastness testing device of this utility model embodiment includes:

[0023] Base 1;

[0024] Pulling components 2, in two sets, are symmetrically installed on the base 1;

[0025] Friction member 3, the friction member 3 being disposed on the base 1;

[0026] The color card holder 4 is fixed on the base 1;

[0027] The drive mechanism 5 is connected to the pulling component 2 via a transmission.

[0028] Specifically, sample loading: Tie the two ends of the polyester fabric into the pull rings 204 on both sides respectively, adjust the material of the friction pad 308 (for example, use cotton pads when testing dry rubbing color fastness, and use wet cotton pads when testing wet rubbing), and turn the knob to make the friction pad 308 stick tightly to the fabric (the pressure is controlled by the screw torque, with a preset value of 0.5 N·m).

[0029] Operation: Start the drive motor 506, drive the gear 505 to rotate, alternately drive the two drums 202 to wind / unwind, and the polyester cloth moves back and forth on the surface of the friction plate 308 (stroke 80mm, speed 100mm / s) to simulate the actual friction scenario (such as the friction of the fabric when wearing clothing).

[0030] Test: After 100 rubbing cycles (the number can be set by the motor controller), stop the operation, take out the color matching card, compare the color of the rubbing area of ​​the fabric with the color matching card, and evaluate the color fastness grade according to GB / T3920 standard (staining gray card grade 1-5).

[0031] In one embodiment of this utility model, the pulling component 2 includes:

[0032] The stand 201 is fixed to the base 1;

[0033] The drum 202 is rotatably connected to the stand 201;

[0034] The tape 203 is wound around the drum 202 at one end and has a pull ring 204 at the other end.

[0035] Specifically, in the pulling component 2, the stand 201 is a three-dimensional support structure made of aluminum alloy, with a 50mm diameter nylon drum 202 installed inside. The two ends of the drum can rotate flexibly through bearings, and the spiral groove design on its surface can guide the winding tape 203 to wind evenly and avoid deviation. The winding tape is made of 15mm wide high-strength polyester fiber tape, and the winding tape 203 can stably clamp the edge of the polyester fabric, and the reciprocating pulling of the fabric is achieved in conjunction with the winding and unwinding action of the drum.

[0036] In one embodiment of this utility model, the friction member 3 includes:

[0037] A clamping seat 301 is fixed to the base 1;

[0038] The first clamping block 302 is fixed to one side of the clamping seat 301;

[0039] The movable block 303 is slidably connected to the slide rail 305 inside the clamping seat 301, and a second clamping block 304 is fixed thereon.

[0040] Screw 307, which passes through the threaded bearing seat 306 on the clamping seat 301, and is threadedly connected to the moving block 303;

[0041] Friction plate 308, the number of friction plates 308 is two sets, the friction plates 308 are sandwiched between the first clamping block 302 and the second clamping block 304.

[0042] Specifically, the end knob drives the moving block 303 to move closer to or further away from the first clamping block 302, thereby adjusting the contact pressure between the two sets of friction plates 308 and the polyester fabric. The friction plates 308 adopt a detachable design and are embedded into the clamping block slot through elastic buckles. Different materials such as cotton and wool can be replaced according to the testing standards to meet the requirements of dry / wet rubbing color fastness testing.

[0043] In one embodiment of this utility model, the driving mechanism 5 includes:

[0044] Drive motor 506;

[0045] A drive gear 505 is connected to the output shaft of the drive motor 506;

[0046] The first incomplete gear 503 and the second incomplete gear 504 are both meshed with the drive gear 505.

[0047] The first gear 501 and the second gear 502 are coaxially connected. The first gear 501 is coaxially connected to the first incomplete gear 503, and the second gear 502 is coaxially connected to the second incomplete gear 504.

[0048] A shaft 508 is rotatably connected to a base 1. Both ends of the shaft 508 are provided with bevel gears 507. The input shafts of the two sets of pulling components 2 are provided with input bevel teeth. The two sets of bevel gears 507 are respectively meshed with the two sets of input bevel teeth.

[0049] Specifically, the drive mechanism 5 has a first incomplete gear 503 and a second incomplete gear 504 meshing on its two sides respectively. Both are half-tooth structures (tooth ratio of 180° circumference) and the tooth positions are complementary, ensuring that when the drive gear rotates, it alternately drives the first gear 501 and the second gear 502 (both coaxial with the incomplete gear) to rotate in one direction. The shaft 508 is horizontally mounted on the base 1 through a deep groove ball bearing, and bevel gears 507 are installed at both ends. It forms a 90° transmission with the input bevel gear (same module) of the pulling component, converting the rotational power of the gear set into the winding and unwinding action of the drum, realizing the reciprocating alternating pulling of the two pulling components 2. With the motor speed control (preset 10 rpm), it can accurately simulate the reciprocating frequency and stroke required for standard friction testing.

[0050] In one embodiment of the present invention, the friction plate 308 is detachably connected to the first clamping block 302 and the second clamping block 304.

[0051] Specifically, the friction plate 308 has T-shaped slots at both ends, which slide and cooperate with the T-shaped guide rails inside the first clamping block 302 and the second clamping block 304. After insertion, it is locked by the side elastic buckle. When disassembling, pressing the buckle can quickly replace it, which meets the switching requirements of different testing standards (such as GB / T3920, ISO105-X12) for friction materials (cotton / wool) and improves the versatility of the device.

[0052] In the actual operation process: 1. Sample preparation. Insert both ends of the polyester fabric sample into the pull rings 204 of the two-sided pulling components 2, and use the anti-slip teeth on the inside of the pull rings to clamp the edge of the fabric.

[0053] According to the testing standards (such as dry friction or wet friction), the friction pad 308 (such as cotton pad or wet cotton pad) in the friction component 3 can be quickly replaced through the T-shaped slot and elastic buckle, and the friction pad is clamped between the first clamping block 302 and the second clamping block 304.

[0054] Rotate the knob at the end of the screw 307 of the friction component 3 to drive the moving block 303 to slide along the slide rail 305, adjust the contact pressure between the friction plate 308 and the polyester fabric (preset screw torque 0.5 N·m), and ensure that the friction plate is in close contact with the fabric surface.

[0055] Insert a standard color matching card (such as GB / T3920 staining gray card) into the card slot of the color matching card holder 4 to facilitate subsequent color comparison.

[0056] II. Drive Operation. Start the drive motor 506, and its output shaft drives the drive gear 505 to rotate, which in turn meshes with the first incomplete gear 503 and the second incomplete gear 504 in sequence. Since the tooth distribution angles of the two are complementary (each occupies 180° of the circumference), the drive gear 505 drives the first gear 501 and the second gear 502 to rotate alternately in one direction when rotating.

[0057] The first gear 501 and the second gear 502 mesh with the input bevel gears of the pulling assembly 2 through the bevel gears 507 at both ends of the shaft 508, transmitting rotational power to the drum 202, thereby realizing the alternating winding and unwinding of the two drums.

[0058] The spiral grooves on the surface of the roll 202 guide the roll 203 to wind evenly, causing the polyester fabric to reciprocate linearly on the surface of the friction plate 308 (stroke 80mm, speed 100mm / s), simulating the friction scenario in actual wear.

[0059] III. Friction Detection and Data Acquisition. The motor controller presets the number of friction cycles (e.g., 100 times), and the drive motor 506 automatically stops after the set number of cycles is reached.

[0060] After stopping the operation, take out the polyester fabric sample and observe the color change of the rubbing area. Compare it with the standard color card on the color card holder 4. According to the GB / T3920 standard, the color fastness grade is evaluated by the staining gray card (grades 1-5): grade 5 is no staining (best color fastness), and grade 1 is severe staining (worst color fastness).

[0061] IV. Reset and Replacement. If repeated testing or sample replacement is required, loosen the friction plate 308 by rotating the screw 307 in the reverse direction, remove the old sample and install the new sample; if switching testing standards (such as dry / wet friction) is required, the friction plate material can be quickly disassembled and replaced.

[0062] The drive mechanism 5 can be reset manually or automatically, so that the drum 202 of the two-sided pulling components 2 returns to its initial position, ready for the next inspection.

[0063] In summary, the polyester fabric rubbing color fastness testing device of this utility model embodiment stably realizes the reciprocating rubbing action of polyester fabric. The adjustable structure of the rubbing component facilitates adaptation to different testing needs. The integrated design of the color card holder and the testing area simplifies the color comparison process. The overall structure is compact and practical, and can efficiently complete the rubbing color fastness testing of polyester fabric, improve the convenience of testing operation and the intuitiveness of result comparison, and meet the actual application needs of quality testing in the textile industry.
