Rubbing Color Fastness Tester

Manual friction fastness tester is the most commonly used instrument for the textile industry to detect the color fastness of the fabric to dry and wet rubbing. Under certain conditions, the sample is rubbed against the standard small white cloth. Assess the degree of color  transfer to the small white cloth with gray scale. The tester is equipped with crank arm, counter, stainless steel sample holder, 16mm or 25mm diameter test head (providing 9N + 10% vertical pressure).

Application

This instrument is applicable to the test of color fastness in textile, knitwear, leather, electrochemical plate and printing

Accessories and consumables:

1. Friction cloth clamping clip

2. Standard friction sandpaper

3. Small white friction cloth (AATCC/ISO standard)

4. Friction small white cloth (SDC)

5. Calibration fabric

6. Grey card (color) -ISO/BS standard

7. Grey card (stained) -AATCC standard

Standards 

BS 1006 D02: Textiles—Tests for colorfastness—Part D02: Colorfastness to rubbing

ISO 105 D02 X12: Textiles—Tests for colorfastness—Part D02: Colorfastness to rubbing

AATCC 8 & AATCC 165: Standards of the American Society of Textile Chemists and Dyestuffs

GB/T 3920: Textiles—Tests for colorfastness—Colorfastness to rubbing

Feature

1. Strong Standard Compatibility

It is presumed to comply with core domestic and international testing standards such as GB/T 3920. ISO 105 X12. and AATCC 8. meeting the friction color fastness testing needs of various industries including textiles, leather, and coated materials. It is compatible with both dry and wet friction testing scenarios.

2. Precise and Controllable Test Parameters

As a professional testing device, it is likely equipped with standard friction heads (such as 16mm circular or 16mm × 25mm rectangular), applying a stable pressure of approximately 9N. Key parameters such as friction stroke and speed (e.g., 60 cycles/minute) can be precisely adjusted, ensuring the repeatability and accuracy of test data.

3. Optimized Operation and Efficiency

It may feature a single-station or multi-station design (to accommodate different testing volume requirements), utilizing an electric drive system and supporting automatic stop and alarm after a preset number of friction cycles. It is likely equipped with a simple operating interface (such as a touchscreen) for easy parameter setting and sample loading/unloading, reducing manual operation costs.

4. Durable Structure and Easy Maintenance

The machine body is likely made of high-strength materials such as aluminum alloy, and the friction moving parts use wear-resistant materials, ensuring smooth and quiet operation. The design emphasizes ease of maintenance, requiring no frequent or complex maintenance, extending the equipment's lifespan.

Test Procedures

1. Sample preparation:

1. 1 The sample and standard small white friction cloth need  to be moisturized in a constant temperature and humidity environment.

1. 2 When the sample has many colors, all colors should be rubbed.

1. 3 if the area of various colors is large enough,take different colored smaple separately.

1. 4 To make dry friction and wet friction, ensure that all colors are rubbed.

1. 5 If the two sides of the sample are made of different materials and colors, the test will be done on both the two sides.

1. 6 Dry and wet rubbing fastness test should not be repeatedly done in the same part of the sample.

2. Dry friction:

2. 1  Place the sample flat on the tester with sandpaper laid on. Make the lengitudinal direction of the specimen consistent with the moving direction of the instrument and fix the sample on the pressing plate, and the sample should be flat.

2. 2 Apply the standard friction cloth to the friction head, tighten with the spring clamp, and place the friction head on the sample.

2. 3 Ensure that the sample has no slip or wrinkle when the friction starts;

2. 4 Put the friction head on the sample. Connect the POWER and press the POWER button. Set test times.

2. 5 Start the test by pressing the START button. When the test number reaches the set value, the instrument automatically stops.

2. 6 Remove the standard white friction cotton cloth and compare for rating with the gray card.

3. Wet friction:

3. 1 Completely wet the standard friction cloth in distilled water;

3. 2 Squeeze the friction cotton in the filter paper after taking out, but contain certain water content;

3. 3 The remaining steps are the same as the above dry friction test;

4. Result processing:

4. 1 Before rating, use scotch tape to gently stick the loose fluff off the white cloth.

4. 2 Place three layers of unused friction white cloth under the white cloth to be assessed, and the color rating of the small white cloth should be evaluated by reference to the standard stained grey scale.

5. Test report:

5. 1  Report standard method

5. 2  Report dry friction and wet friction results respectively.
