Description

Technical Field

[0001] This utility model relates to the field of fabric testing technology, and in particular to a multifunctional color fastness testing device for elastic woven fabrics. Background Technology

[0002] Elastic woven fabrics are widely used in sportswear, casual wear, and other fields due to their excellent stretch and resilience. Colorfastness is a key quality indicator of the fabric, directly affecting the product's appearance retention, durability, and safety when worn.

[0003] Currently, the testing of indicators such as wash fastness, rubbing fastness, and light fastness mainly follows national standards, requiring separate testing using specialized equipment such as wash fastness testers, rubbing fastness meters, and xenon arc lamp weathering testers. This decentralized testing model suffers from problems such as high equipment purchase costs, large laboratory space requirements, cumbersome operating procedures, and long processing times, especially when conducting comprehensive evaluations of samples across multiple parameters, resulting in low efficiency.

[0004] While some improved single-function testing devices exist in the existing technology, there is no integrated device that can effectively integrate the above-mentioned multiple core color fastness testing functions. To reduce costs and increase efficiency, we propose a multifunctional color fastness testing device for elastic woven fabrics. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-3 As shown, this embodiment is a multifunctional color fastness testing device for elastic woven fabrics, including a washing tank 1, a column 2 fixedly connected to the outer side of the bottom wall of the washing tank 1, a drive motor 3 fixedly connected to the center of the bottom wall of the washing tank 1, a central shaft 4 fixedly connected to the top output end of the drive motor 3, an agitator 5 connected to the outer wall of the central shaft 4, a bracket 6 fixedly connected to the top of the washing tank 1, a positioning box 7 fixedly connected to the upper end of the bracket 6, multiple strip-shaped openings 8 circumferentially opened on the side wall of the positioning box 7, a lifting seat 9 inside the positioning box 7, and a PLC controller 100 connected to the outer wall of the washing tank 1. By using the drive motor 3 to drive the central shaft 4 and the agitator 5 to rotate, the washing environment can be simulated to test the color fastness to washing.

[0023] A door 11 is hinged to the upper part of the outer wall of the washing tank 1. A drain pipe 12 is connected to the lower end of the washing tank 1. A control valve 13 is installed at the end of the drain pipe 12 to facilitate sample loading and washing solution replacement. A xenon arc lamp 14 is fixed to the top of the inner wall of the washing tank 1 to simulate sunlight irradiation. A transparent bag 15 is fixed to the lower part of the outer wall of the washing tank 1. A sample card 16 is inserted into the transparent bag 15 for comparison and rating.

[0024] The lower end of the positioning box 7 has a guide hole 71, and a guide rod 72 is movably inserted into the guide hole 71. The upper end of the guide rod 72 is fixedly connected to the lifting seat 9, and the lower end of the guide rod 72 is fixedly connected to the stop block 73. A return spring 74 is installed between the stop block 73 and the positioning box 7.

[0025] The bracket 6 is rotatably connected to a driven shaft 61. A bevel gear ring 62 and a cam 63 are fixed to the outer wall of the driven shaft 61. The upper end of the cam 63 abuts against the lower surface of the stop block 73. The bevel gear ring 62 is meshed with a bevel gear 64. The center of the bevel gear 64 is fixed to the upper end of the central shaft 4, which enables the central shaft 4 to rotate and the lifting seat 9 to rise and fall simultaneously.

[0026] A screw 91 is rotatably connected to the top center of the lifting seat 9. A knob 92 is fixed to the upper end of the screw 91. A nut seat 93 is screwed to the outer wall of the screw 91. A horizontal slide rail 94 is opened on the outer side of the top of the lifting seat 9. A slider 95 is slidably connected in the horizontal slide rail 94. A traction rod 96 is hinged between the top of the slider 95 and the nut seat 93. A friction head 97 is detachably installed at the end of the slider 95, which can perform abrasion fastness testing.

[0027] The friction head 97 is located between two adjacent strip openings 8, which facilitates friction treatment of the fabric.

[0028] The specific implementation method of this utility model is as follows:

[0029] When using this device, an external power supply is used. The elastic woven fabric sample to be tested is sewn with a standard lining fabric. After opening the door 11, it is placed in the washing tank 1 and a standard washing solution is added. Another set of samples is cut into strips and passed through the strip opening 8 of the positioning box 7 and then tied in place. The friction head 97 faces the fabric. The PLC controller 10 is used to start the drive motor 3. The central shaft 4 can drive the stirring blade 5 to rotate, thereby simulating the standard washing process. After the test, the control valve 13 is opened to discharge the liquid. After taking out the sample, it is dried according to the standard and compared with the sample card 16 for rating. It can complete the test of wash fastness. When the washing tank 1 is in a dry state, the sample and the blue wool standard sample are put into the xenon arc lamp 14 to irradiate the sample. After the irradiation, the degree of color change of the sample and the blue wool standard sample is compared to determine the light fastness grade.

[0030] While the central shaft 4 rotates, the top bevel gear 64 meshes with the transmission bevel gear ring 62, causing the driven shaft 61 to drive the cam 63 to rotate. The cam 63 periodically pushes the stop block 73, and the return spring 74 is used to reset it, so that the guide rod 72 can drive the lifting seat 9 to move up and down reciprocally. Vertical reciprocating friction is generated between the strip sample and the friction head 97. After the test is completed, the friction head 97 is removed, and the color fastness to rubbing is rated according to its degree of staining and compared with the sample card. The color fastness to rubbing can be tested. The screw 91 is rotated by rotating the knob 92, and the nut seat 93 can move up and down along the screw 91. The traction rod 96 pushes and pulls the slider 95 to move in the horizontal slide 94, which can adjust the normal pressure of the friction head 97 on the sample, thereby meeting different test requirements and improving the accuracy of the test results.

[0031] This device integrates multiple functions, including stirring, lifting and reciprocating, and pressure adjustment. It can integrate three major testing functions—washing, friction, and light exposure—into one device, saving space and cost.
