Random Tumble Pilling Tester
Random Tumble Pilling Tester
The Random Tumble Pilling Tester is a specialized instrument designed to assess the pilling resistance of textile fabrics. Pilling refers to the formation of small, fuzzy balls (pills) on the fabric surface due to wear and friction. This tester simulates the wear conditions that fabrics experience during actual use, providing valuable data on their durability and appearance retention.
Purpose of Random Tumble Pilling Tester
The primary function of the Random Tumble Pilling Tester is to evaluate how fabrics resist pilling, fuzzing, and matting. This assessment is crucial for manufacturers aiming to ensure the longevity and aesthetic quality of their textile products.
Working Principle of Random Tumble Pilling Tester
The tester operates by placing fabric specimens into cylindrical test chambers lined with cork. Inside each chamber, a stainless steel impeller rotates at a high speed (typically around 1200 revolutions per minute), causing the fabric samples to tumble randomly. Compressed air is injected to enhance the tumbling action. This process simulates the friction and wear that fabrics undergo during regular use. After a predetermined duration, the samples are removed and visually assessed for pilling using standardized rating scales.

Features of Random Tumble Pilling Tester:
- Multiple Test Chambers – Typically comes with 2 or 4 cork-lined chambers for simultaneous testing of multiple fabric samples.
- High-Speed Rotating Impellers – Impellers rotate at around 1200 rpm to create intense, random tumbling motion.
- Compressed Air System – Ensures continuous fabric movement and realistic simulation of wear.
- Digital Timer- Allows precise setting of test duration with easy-to-read display.
- Viewing Windows- Transparent chamber doors for monitoring fabric movement during testing.
- Standard Compliant Design- Meets ASTM D3512, ISO 12945-3, GB/T 4802.4 and other major standards.
- Robust Construction- Durable materials and components designed for long-term laboratory use.
- Easy Sample Handling – Quick-open chamber lids and simple sample placement process.
- Compact Footprint- Saves space in laboratory environments.
How to Use Random Tumble Pilling Tester:
- Prepare Samples- Cut fabric into standard-sized specimens (usually circular or rectangular per ASTM/ISO specs)- Condition samples as per the standard (usually 24 hrs at 21°C, 65% RH).
- Load the Chambers – Place each sample into a cork-lined test chamber. – Add a small piece of gray cotton backing fabric if required by the method.
- Set Parameters – Adjust compressed air pressure (typically 14–21 kPa or 2–3 psi).
– Set the test time (e.g., 30–60 minutes) using the digital timer.
- Start the Test- Close the chamber doors and press start. – Impellers rotate, tumbling the samples randomly with air flow.
- Stop and Unload – Once the timer ends, remove the samples carefully.
- Evaluate Pilling – Compare the tested samples to standard pilling rating photographs or scales.
– Assign a rating from 1 (severe pilling) to 5 (no pilling).
- Record Results – Document the pilling grades and any observations.
