The Rubbing color fastness tester is an instrument for testing whether textiles fade or stain when rubbed. It can simulate different rubbing conditions, such as dry rubbing, wet rubbing, organic solvent rubbing, etc., to evaluate the color fastness performance of textiles. rubbing color fastness tester is widely used in apparel, home textiles, automotive interiors, and other fields, and is an important tool for textile quality control.

So, what are the key factors to consider when choosing a rubbing color fastness tester? In this blog post, I will introduce five tips for choosing a rubbing color fastness tester, which I hope will help you make an informed decision.

What are the key factors to consider when selecting a rubbing color fastness tester?

1. Standards compatibility. Different countries and regions have different standards and specifications that require the use of different rubbing color fastness testing methods and parameters. Therefore, when choosing a rubbing color fastness tester, make sure it can meet the standards you need, such as GB/T 3920, ISO 105-X12, AATCC 8, etc. If you need to meet more than one standard at the same time, then it is best to choose a rubbing color fastness tester that can automatically switch between different test modes and conditions, which can save time and cost.

2. Friction head design. The friction head is the core component of the rubbing color fastness tester, which directly contacts the sample under test and determines the accuracy and stability of the test. In the selection of rubbing color fastness tester, pay attention to the friction head shape, size, weight, material and other factors, whether it meets the standard requirements. In general, the rubbing head should be round or square, size 9 × 9cm or 5 × 5cm, weigh 900g or 550g, and material of stainless steel or white brass. In addition, also pay attention to whether the friction head can automatically adjust the pressure and angle to adapt to different textile types and thicknesses.

3. Friction speed and the number of times. Rubbing speed and the number of times is an important parameter affecting the rubbing color fastness test results, they reflect the actual use of textiles subjected to the intensity and frequency of friction. In the choice of rubbing color fastness tester, according to the standard requirements or their own needs, choose the appropriate friction speed and a number of times. In general, the rubbing speed is 30 to 60 times per minute and the number of times is 10 to 100. If you need to conduct more demanding or more flexible testing, then it is best to choose a rubbing color fastness tester that can freely set the speed and number of rubbing.

4. wet white cloth supply method. Wet white cloth is the standard material used for wet rubbing test, it can visually show the degree of fading or staining after rubbing with the sample under test.
