Description

Technical Field

[0001] The invention relates to the technical field of color fastness detection, in particular to a detection device for detecting color fastness of fabrics. Background Art

[0002] Fabric color fastness testing is an important means to evaluate the color stability of fabrics. It usually uses friction color fastness test, washing color fastness test, light color fastness test, perspiration color fastness test, chemical reagent color fastness test and other methods to test color fastness. Among them, the washing color fastness test is used to evaluate the color stability of fabrics during the washing process. It is often divided into home washing color fastness test and industrial washing color fastness test. When conducting a home washing color fastness test, it is necessary to simulate the home laundry environment, put the fabric sample into water containing standard detergent for washing, and evaluate the color change of the fabric after washing. After the fabric is contaminated by pollutants, the fabric is washed with a mallet, which is a common washing method in daily life. The existing washing color fastness detection device can only imitate the working mode of the washing machine to wash the fabric, resulting in poor detection effect.

[0003] The patent document with announcement number CN209894668U discloses a textile washing color fastness test device, including a device housing, a cover plate, a groove, a clamping device, a container, a driving motor, a connecting block, a stirring roller, a rotating block, a stirring rod, a motor support seat, a heating plate, a supporting plate and a drain pipe. The top of the device housing is provided with a groove, one side of the groove is provided with a cover plate, the cover plate is rotatably connected to the device housing through a hinge, one side of the groove is provided with a clamping device, and one side of the clamping device is provided with a container. This textile washing color fastness test device can not only effectively test the washing color fastness of textiles, but also simply disassemble the container through the clamping device, and then clean the container, which will not affect the next test of the textile, the test is more accurate, the detection accuracy of the process is improved, and the production efficiency is improved under the premise of ensuring the quality of the product. However, the patent still has the following problems in actual use: The washing color fastness testing device can only realize the washing process of the fabric by rotating the stirring roller. When in use, it is difficult to simulate the process of hitting the fabric with a mallet during the home washing process, resulting in a poor effect of the washing test. In addition, the method of stirring the fabric sample with a stirring roller can easily cause the fabric sample to be entangled in the stirring roller, resulting in poor contact between the fabric and the cleaning solution, and easily causing damage to the fabric sample, thereby affecting the effect of the fabric color fastness test.
