Q1: What is an electronic rubbing fastness tester?
A1: The electronic rubbing fastness Tester is a device used to test the color fastness performance of textiles, printed materials, or leather materials under dry/wet friction.
Evaluate whether dyes or pigments fall off or transfer during the friction process by simulating the friction process.

Q2: What materials is the electronic rubbing fastness tester suitable for?
A2: This device is suitable for various dyed or printed fabrics, leather, and synthetic leather, paper printing products, coating materials, and other samples that require friction fastness testing.

Q3: What is the working principle of an electronic rubbing fastness tester?
A3: Friction color fastness test is a method of simulating the friction scenario generated during actual wearing or use by repeatedly rubbing a standard friction white cloth against the tested sample under certain pressure and frequency. After the test is completed, observe whether there is staining transfer on the white cloth and compare the ratings using a gray card. It is usually divided into 5 levels, with 5 indicating no staining transfer and 1 indicating severe staining transfer.

Tips: How to use an electronic rubbing fastness tester?
An electronic rubbing fastness tester is a testing device used to determine the colorfastness of textiles to rubbing—also known as crocking. It helps check how much dye rubs off a fabric when it’s dry or wet. Here's a step-by-step guide on how to use a crockmeter properly:

1. Prepare the Sample: Cut a test specimen of the fabric (typically around 5x5 cm or larger depending on the crockmeter model).Place the fabric sample flat and securely on the base of the crockmeter, with the side to be tested facing up.

2. Prepare the Test Cloth: Use a standard white crocking cloth (usually cotton). For wet tests, moisten the crocking cloth with distilled water (not dripping wet—just damp).

3. Mount the Crocking Cloth: Wrap the crocking cloth tightly around the crockmeter finger (the rubbing head). Make sure there are no wrinkles or loose parts.

4. Set the Crockmeter: Place the rubbing finger (with the crocking cloth) in contact with the fabric sample. Typically, the crockmeter applies a standard pressure (around 9 N or 900 grams depending on standard used).

5. Run the Test: Operate the machine to perform a set number of rubs. Some machines are manual (turning a crank), others are motorized.

6. Evaluate the Result: Remove the crocking cloth after the test. Compare the amount of color transfer on the crocking cloth using a gray scale for staining.
