When people wear clothes or wash clothes for a long time, the fiber head on the surface of the fabric will be loose due to friction and sliding, which will be exposed on the surface of the fabric, forming fuzz. Because of their good wear resistance, these trichomes will tangle into small balls when they continue to be subjected to external friction. Pilling is one of the important factors affecting the hand feel, appearance and wearing performance of the fabric, and also an important indicator of the quality of clothing products. There are four common methods for Pilling Test: circle track method, Martin Dale method, rolling box method and random rolling method. At present, our company can provide you with the following two test methods.

Testing of physical and chemical properties of fabrics, including but not limited to cotton, linen, silk, woolen, leather fabrics, chemical fiber fabrics, blended fabrics, modal fabrics, etc

1. Circle track method

This method is widely used in woven and knitted fabrics.

Test principle:

According to the specified method and test parameters, nylon brush and fabric abrasive or only fabric abrasive shall be used to make the sample friction and pilling. Then the pilling performance was evaluated by visual description under the specified light conditions. Parameters of circle track method can be selected according to fabric type, and those with product standard can be selected according to product standard requirements: such as GB / t4802.1-2008.

2. Martin Dale method

This method is mainly used for knitted fabrics, woven fabrics, especially home textile products.

Test principle:

Under the specified pressure, the circular sample is rubbed with the same fabric or wool abrasive fabric with the locus of Lissajous pattern. The specimen can rotate freely around the central axis perpendicular to the plane of the specimen. After the specified friction stage, the pilling or pilling grade of the sample shall be evaluated by visual description.

Common standards: such as GB / t4802.2-2008 iso5670, bs3424 / 5690, BS EN iso12947-1, BS EN iso12945-2, etc.

3. roll box method

This method is mostly used in knitted fabrics, especially wool fabrics.

Test principle:

The test sample installed on the polyurethane pipe shall be overturned in the wooden box with constant rotation speed and cork lining. After the specified turning times, the pilling and / or pilling performance is evaluated by visual description.

Common standards: GB / T 4802.3, ISO 12945.1, bs5811, JIS l1076, IWS tm152, M & sp18, p18b, p18c, p21a, next19, etc

4. Random roll method

Test principle:

The pilling performance of the fabric can be tested by the random turning pilling tester. Under the rotating action of stainless steel blade in the independent stainless steel sample test room, the continuous, random friction and test time between the fabric to be tested and cork lining are controlled by timer and audio alarm. Compressed air can also be injected into the test room to enhance the overturning and friction.

Common standards: GB / t4802.4, iso12945.3, ASTM d3512, ASTM d1375, etc.
