Electric friction decolorization testing machineA smart testing device developed according to standards such as ASTM F1319, AATCC 8/165, BS 1006 D02, GB/T 3920, IS0 105 D02/112, JIS L0849, M&S C8/C8A, NEXT TM6, etc.

Electric friction decolorization testing machine suitable for the industry

This instrument is suitable for all fabrics on or inside textiles such as yarn, yarn dyed, printed and dyed, as well as toy products

The electric friction decolorization testing machine is designed as a whole, mainly composed of a base, a friction transmission mechanism, and a counter. The sample and sandpaper are fixed on one side of the base with a sample clamp. The handle is shaken to make the friction head with white cotton cloth move back and forth on the sample with a specified stroke, causing the white cotton cloth and the sample to rub against each other. After ten frictions, the degree of color adhesion on the white cotton cloth is observed and compared with a gray card to evaluate the stability of the dyeing or surface coating of the fabric sample, providing reference data for material evaluation and selection.

sample preparation

1.1 The sample and standard friction white cloth shall be conditioned in a constant temperature and humidity environment.

When the sample has multiple colors, all colors should be rubbed together.

1.3 If the area of each color is large enough, separate samples must be taken.

1.4 Cut the sample and perform dry friction and wet friction separately, ensuring that all colors are rubbed.

If the front and back of the sample are made of different materials and colors, both sides must undergo an open abrasion color fastness test.

1.6 Dry and wet rubbing fastness should not be repeated in the same part of the sample.

dry friction

2.1 Place the sample flat on the friction tester with sandpaper, ensuring that the length direction of the sample is consistent with the movement direction of the instrument, and fix the sample on the pressure plate. The sample should be clamped flat.

2.2 Fix the standard friction white cloth on the friction head, clamp it with a spring clip, and gently place the friction head on the sample;

2.3 It should be ensured that the sample does not slide or wrinkle during friction;

2.4 Place the friction head on the specimen. Connect the power and press the POVER button. Set the number of tests.

Press the START button to start the test. When the number of tests reaches the set value, the instrument automatically stops.

2.6 Remove the standard friction white cotton cloth and compare and grade it using a color chart.

Wet friction

3.1 Fully immerse the standard friction white cloth in distilled water;

3.2 After removal, squeeze it into filter paper to achieve a certain moisture content;

3.3 The remaining steps are the same as the dry friction test steps mentioned above;

Result processing

Before rating, gently use transparent adhesive to remove loose fluff from the white cloth.

4.2 Place three layers of unused friction white cloth under the friction white cloth to be evaluated, and evaluate the staining level of the friction small white cloth according to the standard staining gray card.
