The rotary rubbing colorfastness tester is an instrument used to test the colorfastness of textiles by simulating the color changes of the garment during rubbing and washing. This article will introduce the technical specifications of the rotary rubbing color fastness tester in detail to help users better understand and use the instrument.
First, the test principle.
The rotary rubbing colorfastness tester uses a rotary friction device to evaluate the color fastness of a specimen by rubbing it against a standard cotton cloth to simulate the mechanical action during the actual washing process. The instrument can be widely used to test the color fastness of cotton, wool, silk, linen and other textiles.
Second, technical indicators.
1.Test head material: made of high-quality stainless steel material, corrosion resistance, improve service life.
2.Test pressure: Adjustable test pressure to adapt to different thickness specimens to ensure the accuracy of test results.
3.Test speed: Adjustable test speed to meet different test needs and ensure the reliability of test results.
4.Rotation mode: The rotation mode without JI speed regulation is adopted, which is convenient for users to adjust the rotation speed according to different samples.
5.Friction times: The friction times can be set to meet the test requirements of different standards.
6.Auto-stop: Equipped with an auto-stop function, the instrument will automatically stop rotating when the preset number of frictions is reached.
7.Data processing: The instrument can automatically record the test data and generate a test report, which is convenient for users to analyze and process the test results.
8.Specimen grips: High-precision grips are used to ensure that the specimen will not slip or shift during the test.
9.Power supply: It supports two power supply modes: AC and DC, which is convenient for users to choose according to different needs.
10.Dimensions: Compact and lightweight, easy for users to move and operate.
3. How to use.
1.The textile sample to be tested is placed on a standard cotton cloth and secured with a clamp.
2.According to the requirements of the test standard, adjust the parameters such as test pressure, speed and number of frictions.
3.Press the start button to start the test.
4.During the test, observe the friction between the specimen and the standard cotton cloth and record the test data.
5.When a preset number of frictions is reached, the instrument automatically stops rotating.
6.The specimen is removed, the color change is observed, and the test report is recorded.
7.Based on the test data and analysis results, the color fastness of the garment is evaluated.
4. Precautions.
1.Before use, please read the user manual carefully to understand the technical indicators and usage methods of the instrument.
2.Do not use the instrument in wet or rainy weather to avoid damage to the instrument.
3.Do not place anything on the friction head to avoid affecting the test results.
4.During use, if any abnormal situation is found, please stop using it immediately and contact after-sales service personnel for inspection and maintenance in time.
V. Conclusions. Rotary rubbing color fastness tester is a kind of GAO effect, accurate textile color fastness testing instrument, its technical indicators include test head material, test pressure, test speed, rotation mode, friction times, automatic stop, data processing, specimen fixture and power supply, etc. During use, users should adjust the relevant parameters according to the test requirements to ensure the accuracy and reliability of the test results. At the same time, it is also necessary to pay attention to relevant matters in the process of use to ensure the normal use and prolongation of the service life of the instrument.
