Usually includes the following steps. The specific operation may vary slightly depending on the equipment model. Please refer to the equipment manual:

Preparation

1. Check the equipment

① Confirm that all parts of the tensile machine (clamp, handle, dial, etc.) are intact.

② Ensure that the clamp is clean and free of oil or residue to avoid affecting the test results.

2. Calibrate the equipment (first use or regular calibration)

Adjust the pointer to zero according to the manual, or use a standard weight to verify the accuracy of the reading.

3. Prepare the sample

(1) Sew the button to be tested on the standard fabric (or keep the button on the original garment), ensuring that the seam is firm.

(2) Cut the fabric and leave enough area around the button (usually ≥5cm×5cm) for clamping.

Test steps

1. Fix the sample

Upper clamp: clamp the fabric (avoid the seam) and ensure that the fabric is flat and does not slide.

Lower clamp: Clamp the button (if it is a four-hole button, it needs to be fixed with a special clamp or hook).

Note: The direction of the clamp must be consistent with the force direction of the button (such as vertical or horizontal stretching).

2. Start the test

(1) Slowly turn the handle or pull the lever to apply tension at a constant speed (usually the speed recommended is 10-15cm/min).

(2) Observe the connection between the button and the fabric until the button falls off or the stitching breaks.

3. Record data

(1) Read the maximum tension value indicated by the pointer (usually in Newtons N or pounds-force lbf).

(2) Record the damage form when the button falls off (such as stitching breakage, button fragmentation, etc.).

Post-test operation

1. Reset the equipment

(1) Loosen the clamp, remove the sample, and return the handle of the tensile machine to its original position.

(2) Clean the thread or fabric fragments remaining in the clamp.

2. Data analysis

Compare the test results with industry standards (such as ASTM D4846, ISO 13935, etc.) to determine whether the button is qualified.

Precautions

Safe operation: Avoid rapid force or overload testing to prevent the fixture from breaking and injuring people.

Environmental conditions: It is recommended to test in a standard temperature and humidity environment (such as 23±2℃, 50±5%RH).

Multiple tests: It is recommended to test the same button 3-5 times and take the average value to improve accuracy.

Common problem handling

The pointer does not return to zero: Check whether the spring or lever is stuck, and contact the manufacturer for calibration if necessary.

Button slips: Replace the fixture or use an anti-slip pad to enhance the clamping force.

If more detailed guidance is required, please provide the equipment model or refer to the specific manual.

I. Instrument overview

The manual rubbing color fastness tester is used to evaluate the color transfer degree of textiles, leather, coated fabrics and other materials under dry or wet rubbing conditions. The equipment is easy to operate and is suitable for rapid color fastness testing in laboratories or factories. It complies with relevant standards (such as GB/T 3920, ISO 105-X12, AATCC 8, etc.).

II. Test principle

By manually operating the friction device, the standard friction cloth is rubbed back and forth on the surface of the sample with the specified pressure and number of frictions, and the color staining of the friction cloth is observed and compared with the standard grayscale sample card for rating.

III. Operation steps

1. Preparation

Sample preparation:

Cut the sample to be tested with a size of ≥20cm×5cm (adjusted according to the standard), ensuring that the surface is flat, wrinkle-free and stain-free.

Rubbing cloth cutting: Use standard bleached cotton cloth (as specified in GB/T 7568) and cut it into a 5cm×5cm square.

Wet friction test: The friction cloth needs to be soaked with distilled water, and the moisture content is controlled at 100±5% (the moisture can be controlled by wringing).

2. Install the friction cloth

Wrap the friction cloth flatly on the friction head (usually a round friction head with a diameter of 16mm) and fix it with a rubber band or a fixing clip to ensure that there is no looseness or wrinkles.

3. Fix the sample

Spread the sample to be tested flat on the test bench or flat table and fix it with a clamp to prevent movement.

4. Manual friction test

Dry friction test:

1. Press the friction head wrapped with the friction cloth vertically on the surface of the sample.

2. Apply standard pressure (usually 9N or as required by the standard).

3. Rub back and forth 10 times at a uniform speed in the straight direction (one way is about 10cm, speed is about 1 time/second).

Wet friction test:

1. After the friction cloth is soaked, gently squeeze out excess water (avoid dripping).

2. Perform the test according to the dry friction steps. After the friction is completed, remove the friction cloth and dry it immediately.

5. Result evaluation

After the friction cloth is dry (wet friction needs to be dried naturally), compare it with the standard staining gray scale sample card (such as ISO 105-A03) and evaluate the staining level (level 5 is the best and level 1 is the worst).

Record the test results of dry friction and wet friction, and use the lower level as the final evaluation.
