I. Introduction to the instrument

The ICI pilling tester is a professional test device used to evaluate the pilling performance of fabrics under friction, developed by the British Chemical Industry Company (ICI). The instrument quantitatively determines the anti-pilling performance of fabrics by simulating the friction of fabrics in daily use.

II. Instrument composition

1. Test box: accommodates test samples and friction devices.

2. Friction head: with abrasives of specific specifications.

3. Sample fixture: fix the test sample.

4. Counter: record the number of frictions.

5. Control system: set test parameters.

6. Vacuum cleaner: remove fiber scraps generated during the test.

III. Operation steps

1. Preparation before testing

(1) Place the instrument on a stable workbench and ensure it is level.

(2) Connect the power supply and check whether all parts of the instrument are normal.

(3) Prepare standard abrasives and fabric samples to be tested.

(4) Cut samples according to standard requirements (usually circular samples with a diameter of 140 mm).

2. Sample installation

(1) Fix the sample flatly on the sample fixture to avoid wrinkles.

(2) Ensure that there is no initial fuzzing or pilling on the sample surface.

(3) Install the standard abrasive on the friction head.

3. Parameter setting

(1) Set the number of frictions according to the test standard (usually 100-5000 times).

(2) Set the appropriate pressure (commonly 125g or 155g).

(3) Select the test mode (unidirectional or bidirectional friction).

4. Start the test

(1) Close the test chamber door.

(2) Start the instrument and start the friction test.

(3) Observe the sample status during the test (through the observation window).

5. Post-test operation

(1) After the test is completed, turn off the power.

(2) Carefully remove the test sample.

(3) Clean the abrasive and test chamber and prepare for the next test.

IV. Result evaluation

(1) Compare the tested samples with the standard samples for rating.

(2) Commonly used rating standards:

A. 5-level system: 5 is the best (no pilling), 1 is the worst (severe pilling).

B. Text description: none, slight, moderate, severe.

(3) A magnifying glass or microscope can be used for more accurate evaluation.

V. Precautions

1. Calibrate the instrument regularly to ensure the accuracy of the test results.

2. Keep the abrasive clean and in standard condition, and replace it regularly.

3. The test environment should be controlled under standard temperature and humidity conditions (usually 20±2℃, 65±2%RH).

4. Appropriate test parameters should be selected for different fabric types.

5. The sample should be balanced in a standard environment for at least 24 hours before testing.

6. Avoid direct contact with the abrasive surface with your hands during operation.

VI. Maintenance

1. Clean the inside of the instrument after each use

2. Check the lubrication of moving parts regularly

3. Cut off the power supply and cover to prevent dust when not in use for a long time

4. Perform regular professional maintenance as recommended by the manufacturer

By using the ICI pilling tester correctly, the anti-pilling performance of fabrics can be objectively evaluated, providing important data support for textile development and quality control.
