Abstract
Description
Technical Field
[0001] This utility model belongs to the field of textile testing, and in particular relates to a fixture for testing the color fastness of textiles to sunlight. Background Technology
[0002] Sunlight color fastness is a common test item in the color fastness group of textile testing laboratories. The number of daily tests is stable and does not change significantly with the seasons.
[0003] Currently, the national standard method is GB / T 8427-2008. Compared with domestic and foreign sun-drying equipment, Q-SUN equipment is convenient to use, easy to maintain, and has a low operating cost. It is equipped in many textile testing laboratories. It can sun-dry according to both the national standard GB / T 8427-2008 (or ISO 105B02) and the American standard (AATCC TM16), making it an ideal sun-drying machine for many textile testing laboratories.
[0004] The existing equipment uses the manufacturer's standard sample clamps and is equipped with a long-arc xenon lamp and a filter tube. When switching to the standard operating program, the filter tube needs to be replaced. However, replacing the filter tube requires disassembling the lamp while the equipment is off. This is not only time-consuming but also carries the risk of damaging the fragile lamp tube. Frequent replacement of the lamp tube and filter tube easily damages both, especially the more delicate and slender lamp tube. In one laboratory, an experimenter broke a lamp tube while replacing the filter tube. Other laboratories have experienced malfunctions and shutdowns of the sun exposure machine due to improper lamp tube installation or removal.
[0005] To address this issue, a fixture for testing the light fastness of textiles was developed to solve the problem of inconvenient sample taking and placement and filter replacement during textile testing. Utility Model Content
[0006] The main technical problem solved by this utility model is to provide a fixture for testing the color fastness of textiles to sunlight, which allows for the replacement of test samples without shutting down the machine, and facilitates the replacement of equipment. This standard testing method simplifies the difficulty of daily use of the equipment, reduces lamp damage and equipment malfunction alarms caused by lamp replacement, ensures the stability of the experimental testing process, and promotes the optimization of the sunlight exposure machine. It is highly practical.
[0007] To solve the above-mentioned technical problems, the present invention provides a technical solution: a fixture for testing the light fastness of textiles, comprising a fixture body, wherein the fixture body is provided with a hollow mounting cavity with an opening on the front side, and light-transmitting holes and through holes are respectively provided on both sides of the mounting cavity, and ventilation holes are provided on the back side, wherein multiple equally spaced positioning strips are provided on the top and bottom of the mounting cavity to form a first clamping grid, a second clamping grid and a third clamping grid, wherein a first layer of filter glass is provided in the first clamping grid, a second layer of filter glass is provided in the second clamping grid, and a test sample is provided in the third clamping grid, wherein a protruding insert plate is provided on the bottom side of the light-transmitting hole of the mounting cavity.
[0008] In a preferred embodiment of the present invention, the tooling body has a transversely protruding side gripper longitudinally arranged on the back side of the through hole.
[0009] In a preferred embodiment of the present invention, the tooling body is provided with multiple sets of mounting cavities in the longitudinal direction.
[0010] In a preferred embodiment of this utility model, the mounting cavity is provided in two sets.
[0011] In a preferred embodiment of this utility model, a plurality of ventilation holes are arranged longitudinally at equal intervals on the back of the mounting cavity.
[0012] In a preferred embodiment of this utility model, a sheet spring is also provided on the same side of the plurality of positioning strips.
[0013] In a preferred embodiment of the present invention, a baffle plate is also provided in the third compartment of the mounting cavity.
[0014] In a preferred embodiment of this utility model, the shielding plate is provided with a light-transmitting hole.
[0015] The beneficial effects of this utility model are as follows: The fixture for testing the color fastness of textiles to sunlight can change test samples without turning off the machine, and it is very convenient to change the test standard method of the equipment. It simplifies the difficulty of daily use of the equipment, reduces lamp damage and equipment malfunction alarms caused by lamp replacement, ensures the stability of the experimental test process, and also promotes the optimization of the sunlight exposure machine. It has good practicality. Attached Figure Description

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0018] Please see Figures 1-6 As shown, the embodiments of this utility model include: A fixture for testing the color fastness of textiles to sunlight includes a fixture body 1.
[0019] The tooling body 1 is provided with a hollow mounting cavity 2 with an opening on the front side. The mounting cavity 2 is used to install textiles and color fastness testing components.
[0020] The tooling body 1 has light-transmitting holes 3 and through holes 4 on both sides of the mounting cavity 2, and multiple ventilation holes 5 are arranged longitudinally at equal intervals on the back. The light-transmitting holes 3 are used to transmit light, and the through holes 4 and ventilation holes 5 are used to provide ventilation inside the tooling body 1.
[0021] The tooling body 1 has multiple sets of mounting cavities 2 arranged longitudinally. In this application, the mounting cavity 2 is provided in two sets to provide simultaneous operation of two sets of textiles.

[0027] Here, we take the national standard (GB / T 8427) for color fastness to sunlight of textiles and the instrument (Q-SUN Xe-2) setting conditions as an example: According to the national standard (GB / T 8427), the equipment should be set to the exposure conditions such as temperature, humidity and irradiance. Generally, the normal conditions can be selected.
[0028]
[0029] The light source and filter use a xenon arc lamp light source, combined with a Window IR filter (both the inner and outer layers are infrared filter glass sheets).
[0030] Light transmittance requirements: ≥90% for the 380nm-750nm band, and 0% for the 310nm-320nm band to block short-wave ultraviolet radiation.
[0031] Blackboard temperature: 50℃ (under moderate effective humidity conditions).
[0032] Humidity calibration: Daily calibration is required using a humidity control standard (red cotton fabric). When the color difference between the exposed and unexposed parts reaches level 4 on the gray scale, it should be consistent with the color change of level 5 on the blue wool standard.
[0033] Radiation: The radiation in the 300nm-400nm band is 42W / m².
[0034] Blue wool standard sample: Use European Blue Label grade 1-8, and the exposure endpoint is determined according to the degree of color change of the target blue label.
[0035] Prepare the sample according to the standard requirements, then use one hand to grab the side gripping edge 7 of the tool body 1 and pull it out of the equipment, and then use the other hand to grab the insert plate 6 and gently place it flat on the table so that the opening side is facing out.
[0036] The first layer of filter glass is an infrared filter glass placed in the first clamping compartment 9. The second layer of filter glass is an infrared filter glass placed in the second clamping compartment 10. The test sample is clamped together with the shielding plate 13 and placed in the third clamping compartment 11.
[0037] After placing it in place, grasp the side gripping edge 7 of the tool body 1 with one hand and the insert plate 6 with the other hand, and gently place it into the turntable inside the equipment to secure it firmly. Then you can close the door and start testing.
[0038] After the test, gently remove the fixture body 1 and take out the sample and shield 13, and prepare for rating.
