Description

Technical Field

[0001] This utility model relates to the technical field of fabric performance testing, and in particular to a testing device for the washability of fabrics. Background Technology

[0002] Fabric dyeing is an important process in the textile industry. Different dyes and dyeing methods affect the colorfastness of fabrics, that is, the ability of colors to be retained during washing and daily use. Because washing with hot water opens up the fabric fibers, making the dye easier to wash away, and the strong agitation and excessive drying of the washing machine can also cause color fading, it is usually necessary to test the colorfastness of fabrics by subjecting them to multiple simulated washing environments in order to assess their quality.

[0003] In the existing technology, the color fastness of fabrics needs to be washed frequently. After each wash, if the clothes are bleed color, the cleanliness of the water will decrease. If the wastewater mixed with the bleed pigment is used, the pigment may re-adhere to the fabric, affecting the test results of the next washing process. Frequent replacement of clean water will also generate a large amount of wastewater, which will increase the cost of fabric testing. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a testing device for the water resistance performance of fabrics, so as to solve the technical problems mentioned in the background art.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Example:

[0030] Reference Figure 1 - Figure 6 This utility model discloses a testing device for the water resistance performance of fabrics, comprising:

[0031] The base 1 has a circular groove 5 on the top left side and a water storage cavity 6 on the right side.

[0032] A pulsator washer 2 is installed inside a circular trough 5 and is used to wash fabrics;

[0033] The water changing component 3 is located at the bottom of the base 1 and is used to change the water in the impeller washer 2;

[0034] The filter assembly 4 is disposed in the water storage chamber 6. The filter assembly 4 includes a float 41, a filter plate 42, a buzzer alarm 43, and a pressure switch 44. The float 41 is slidably disposed in the water storage chamber 6. A through groove 7 is provided in the middle of the float 41. The filter plate 42 is connected to the through groove 7 through a quick-release piece 8. A slide table 9 is fixedly connected to one side of the float 41. A connecting block 11 is fixedly connected to the inner wall of the water storage chamber 6 above the slide table 9. The buzzer alarm 43 is fixedly connected to the top of the connecting block 11. A pressure switch 44 for turning on the buzzer alarm 43 is fixedly connected to the top of the slide table 9.

[0035] A slide rod 10 is slidably connected to the middle of the slide table 9, and the top end of the slide rod 10 is fixedly connected to the connecting block 11.

[0036] In this embodiment, observation Figure 1 and Figure 2 It can be observed that a circular groove 5 is provided on the top left side of the base 1, and a pulsator washer 2 is installed in the groove 5. The pulsator washer 2 is equivalent to a common pulsator washing machine on the market. By placing the pulsator at the bottom of the washing tub, the motor drives the pulsator to rotate. The rotation of the pulsator generates water flow, causing the fabric to tumble up and down and left and right in the water, thus completing the washing of the fabric.

[0037] After washing, the water needs to be changed and the fabric washed multiple times to test its water resistance. Figure 3 It can be seen that a water storage chamber 6 is provided on the top right side of the base 1, and a water exchange component 3 is provided at the bottom of the base 1 to draw the sewage in the impeller 2 into the water storage chamber 6. After washing, the water in the impeller 2 can be drawn out and injected into the water storage chamber 6, and then new water can be added to the impeller 2 to replace the washing water.

[0038] Since the wash fastness test for fabrics focuses on colorfastness, it measures color fading through multiple washes. Therefore, the test for this fabric will not result in significant color fading, preventing the wastewater from being deeply dyed. However, even this minor color fading will leave a small amount of pigment in the wastewater. This pigment can then re-adhere to the clothing when the wastewater is reused, affecting the test results. Furthermore, frequent changes in the water will generate a large amount of wastewater, increasing the cost of fabric testing.

[0039] Therefore, observe Figure 3It can be seen that a filter assembly 4 is installed in the water storage chamber 6. The filter assembly 4 includes a float 41, a filter plate 42, a buzzer alarm 43, and a pressure switch 44. The float 41 is slidably installed in the water storage chamber 6. A through groove 7 is opened in the middle of the float 41. The filter plate 42 is connected to the through groove 7 through a quick-release piece 8. A slide table 9 is fixedly connected to one side of the float 41. A connecting block 11 is fixedly connected to the inner wall of the water storage chamber 6 above the slide table 9. The buzzer alarm 43 is fixedly connected to the top of the connecting block 11. A pressure switch 44 for turning on the buzzer alarm 43 is fixedly connected to the top of the slide table 9. A slide rod 10 is slidably connected to the middle of the slide table 9. The top of the slide rod 10 is fixedly connected to the connecting block 11.

[0040] When it is time to wash the fabric, first add clean water to the water storage chamber 6. As the clean water is injected, the float 41 will move up, causing the slide table 9 to gradually approach the top of the slide rod 10 until the pressure switch 44 contacts the connecting block 11 and activates the buzzer alarm 43 to indicate that the water is full.

[0041] Then you can put the fabric into the pulsator 2. After the fabric is placed, you can turn on the water exchange component 3 to inject clean water into the pulsator 2. Finally, you can turn on the pulsator 2 to wash the fabric.

[0042] After one washing cycle is completed, the water needs to be changed for a second wash. At this time, the wastewater can be pumped into the storage chamber 6 through the water exchange component 3. As the wastewater is injected, it comes into contact with the filter plate 42. When the wastewater quickly passes through the filter plate 42, any small amount of pigment particles mixed in the wastewater can be adsorbed by the filter plate 42, thus clarifying the water and preventing the continuous use of washing water from affecting the subsequent fabric washing and testing results. As the water level in the storage chamber 6 gradually increases, the float 41 rises again until the buzzer alarm 43 sounds again, at which point the next round of fabric washing can begin, effectively saving water resources.

[0043] The sliding rod 10 can provide assistance when the float 41 moves up and down, making its movement smoother and more stable, so that when the float 41 moves to the top, the pressure switch 44 can stably contact the connecting block 11.

[0044] The filter plate 42 mentioned above uses renewable adsorbents such as activated carbon and ion exchange resins, which are all materials that can adsorb dye molecules and reduce the color of water. They can be used to adsorb a small amount of pigment mixed in the sewage after the fabric is washed, so as to ensure the effect of sewage filtration.

[0045] In a further preferred embodiment of this utility model, such as Figure 3As shown, the water exchange assembly 3 includes a main pipe 31, a branch pipe 32, and a water pump 33. One end of the main pipe 31 is connected to the drain outlet of the impeller washer 2, and the other end is fixedly connected to the top of the water storage chamber 6. The outer wall of the main pipe 31 is connected to the branch pipe 32, and the end of the branch pipe 32 away from the main pipe 31 is connected to the bottom of the water storage chamber 6. The main pipe 31 and the branch pipe 32 are respectively connected to water pumps 33 for pumping water and water injection. After the fabric is washed, the sewage can be pumped away by the water pump 33 on the main pipe 31. Then the sewage will be sprayed out from the top of the water storage chamber 6, thereby ensuring that the sewage comes into contact with the filter plate 42 to achieve sewage filtration.

[0046] After the wastewater filtration is completed, the water filtered at the bottom of the water storage chamber 6 can be injected into the impeller washer 2 through the water pump 33 on the branch pipe 32 to replace the washing water.

[0047] In a further preferred embodiment of this utility model, such as Figure 6 As shown, by connecting a one-way valve 12 at the connection between the main pipe 31 and the branch pipe 32, the water in the branch pipe 32 flows into the main pipe 31 in one direction. This can prevent sewage from entering the water storage chamber 6 through the branch pipe 32 and contaminating the clean water filtered by the filter plate 42 when the main pipe 31 is pumped out, thus further ensuring the filtration effect of sewage.

[0048] In a further preferred embodiment of this utility model, such as Figure 5 As shown, the quick-release part 8 includes a support ring 81 and a connecting frame 82. The support ring 81 is fixedly connected to the bottom of the through groove 7. The connecting frame 82 is placed inside the support ring 81. The filter plate 42 is fixedly connected to the top of the connecting frame 82. This facilitates the quick installation of the filter plate 42 and makes the replacement and maintenance of the filter plate 42 more convenient.

[0049] At the same time Figure 4 It can also be found that the bottom of the support ring 81 is higher than the bottom of the float 41, which can prevent the filter plate 42 located at the top of the quick-release piece 8 from contacting the water when the float 41 is in contact with the water. This prevents water from seeping into the filter plate 42 due to surface tension, thereby preventing the filter plate 42 from being in contact with water for a long time, which would cause the pores inside the filter plate 42, such as activated carbon and ion exchange resin, to be blocked by non-pigment dissolved substances or other impurities in the water, thus reducing its adsorption capacity.

[0050] In a further preferred embodiment of this utility model, such as Figure 3 As shown, a water inlet hole 13 communicating with the water storage cavity 6 is provided on the outer wall of the base 1, and a water inlet connector 14 is installed at the opening of the water inlet hole 13, which facilitates the injection of water into the water storage cavity 6.

[0051] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
