What is the testing principle of the 6-Station Pilling Tester?

The core testing principle of the 6 Station Pilling Tester is based on simulating the abrasion process that textiles experience during daily use. Through standardized friction action, pilling is generated on the fabric surface, and the degree of pilling is then evaluated by comparison with standard reference images.

Key Points of the Testing Principle

Multi-Station Simultaneous Testing

The equipment is equipped with six independent test stations, allowing multiple samples to be tested simultaneously, significantly improving testing efficiency.

Friction Method

The tester uses a Lissajous motion trajectory, where the friction head applies constant pressure and moves in a defined elliptical path. This creates multi-directional friction on the fabric surface, more realistically simulating the complex rubbing conditions experienced during actual wearing.

Test Standards

The testing method complies with major international standards, such as GB/T, ISO, and ASTM, ensuring consistency and comparability of results across laboratories.

Evaluation Method

After testing, the samples are compared with standard pilling reference grades (1–5 scale):

Grade 5: Almost no pilling

Grade 1: Severe pilling

This grading system provides a clear and standardized evaluation of fabric appearance durability.

Control System

The equipment is typically equipped with a digital timer (0–9999 minutes) and a touchscreen or LCD control panel, allowing precise setting of test duration and rotational parameters.

The 6 Station Pilling Tester evaluates fabric pilling resistance by reproducing real-world friction conditions through controlled Lissajous motion. Combined with standardized grading methods and multi-station efficiency, it provides a reliable and repeatable solution for textile performance assessment.

What is the operating procedure for the 6-Station Pilling Tester?

The 6 Station Pilling Tester is equipped with six independent testing stations, allowing multiple groups of samples to be tested simultaneously, significantly improving testing efficiency.

A typical operating procedure is as follows:

1. Pre-Test Preparation

Sample Preparation

Cut samples at a position no less than 1/10 of the fabric width from the selvedge, avoiding wrinkled or defective areas.

Prepare specimens in either 320 mm × 320 mm square shape or Φ175 mm circular shape.

Prepare six specimens per test group (two from left, middle, and right positions), and clearly mark warp and weft directions.

Instrument Calibration

Verify the instrument condition weekly using standard reference fabrics.

Clean nylon brushes with acetone and polish them using 320-grit sandpaper to remove residual fibers and ensure consistency.

2. Test Procedure

Brushing Stage (for brush-type pilling tester)

Install the brushing plate on the rotating platform with bristles facing upward.

Fix all specimens on the fixture with the face side outward, each mounted with a 660 ± 5 g weight and a 3 mm soft rubber pad.

Run the tester for 4 minutes ± 10 seconds.

Pilling Formation Stage

Fix specimens on the rotating platform with the face side upward.

(For certain standards, Series A and Series B samples may be stacked face-to-face.)

Run the tester for 2 minutes ± 10 seconds.

3. Result Evaluation

Compare the tested samples with standard reference images (e.g., ASTM D3512 5-grade photo standards).

Pilling grades are evaluated on a 1–5 scale, with 0.5 increments allowed (e.g., 3.5 grade):

Grade 5: No pilling

Grade 4: Slight pilling

Grade 3: Moderate pilling

Grade 2: Severe pilling

Grade 1: Very severe pilling

4. Precautions

Different standards (ASTM, ISO, GB) may vary in sample size, test duration, brush type, and other parameters. The appropriate method should be selected according to product specifications or customer requirements.

Although the six-station design allows parallel testing, results from each station must be recorded independently to ensure accuracy and traceability.

The 6 Station Pilling Tester evaluates fabric pilling performance through standardized brushing and friction processes. Its multi-station design ensures high efficiency, while strict procedural control guarantees reliable and repeatable test results for textile quality assessment.

How to Maintain a Six-Station Pilling Tester?

To ensure long-term stable operation, measurement accuracy, and service life of the 6 Station Pilling Tester, a systematic maintenance procedure should be followed.

1. Cleaning and Maintenance

After each test, use a soft brush or lint-free cloth to remove fiber debris and dust from the worktable, fixtures, abrasives, and sample holders.

Avoid using corrosive or strong solvent-based cleaning agents, as they may damage metal or plastic components.

If the equipment is equipped with a touchscreen or LCD control panel, clean it with a slightly damp soft cloth. Direct water spraying is strictly prohibited.

2. Lubrication and Mechanical Inspection

Regularly check whether key moving components—such as the drive mechanism, guide rails, and rotating shafts—operate smoothly.

If necessary, apply a small amount of dedicated lubricant according to the instruction manual. Avoid excessive lubrication, which may attract dust accumulation.

Ensure that the six independent stations, counters, and positioning systems operate properly without jamming or deviation.

3. Calibration and Accuracy Verification

At least once a year, perform full calibration, including:

Pressure loading system calibration (e.g., using standard weights such as 9 kPa / 12 kPa)

Verification of rotational trajectory accuracy (Lissajous motion pattern)

Synchronization check of counting systems

Standard fabric samples should be used periodically to verify performance consistency, and pilling grade results should be recorded for comparison.

4. Environmental Control

The equipment should be placed in a clean, stable environment with:

Temperature: 15–30°C

Relative Humidity: 30%–60%

Avoid direct sunlight, strong vibration, and high-humidity conditions to prevent sensor drift and mechanical deformation.

5. Troubleshooting

If issues such as single-station failure, counting errors, or pressure instability occur, check the following first:

Whether the fixture is properly installed

Whether the drive belt or gear system is loose or worn

Whether the sensor is blocked or entangled with fibers

Proper maintenance of the 6 Station Pilling Tester is essential to ensure accurate and repeatable test results. Regular cleaning, lubrication, calibration, and environmental control can significantly improve equipment reliability and extend its service life.
